5.0 Underground Fire Water Supply Mains and Interior Mains

Located within Roof Trusses

5.1 Pipe

Pipe used in underground water mains (loops) for site fire protection shall be a minimum of ten inches in

internal diameter. Six and eight inch pipes (internal diameter) are not acceptable due to excessive

friction loss characteristics. Water conditions shall dictate the schedule of pipe.

Required depth of cover for underground piping shall be in accordance with frost penetration in regional

charts that indicate required depth of cover. Refer to latest edition of NFPA 13 (see attached chart on

depth of bury).

Private fire service mains shall be looped or “gridded” to provide a dual water supply feed arrangement.

NOTE: Interior fire water mains within roof trusses shall only be installed with approval from Corporate

and GRC. Of major concern is the type of occupancies located beneath the interior fire main and for 20

feet in all directions. Not permitted are such occupancies as storage of combustibles, machining

operations using combustible cutting oil, hydraulic oil system under pressure, etc.

Riser lead-ins shall be 8-inch to the alarm check valve. Process Mains (refer to Standard #101) shall be a

minimum of 10-inches (internal diameter).

Sprinkler systems shall be designed so that one 8-inch lead-in main shall supply water to one sprinkler

riser/system. Manifolded sprinkler risers shall not be permitted without written permission from

Corporate.

Except for lead-in mains, water mains shall not be installed under buildings. Risers shall be located

adjacent to exterior walls unless written permission is obtained from Corporate and GRC.

Where existing underground mains and or lead-ins will be abandoned under a new floor slab, the entire

abandoned main shall be filled with grout and capped at both ends. The grout mixture and fill method

shall be specified by Chrysler Manufacturing Engineering Group (ME) and/or the architect.

Pipe type shall be restricted to the following:

- Cast iron

- Ductile iron

- Steel

- Polyvinyl Chloride (PVC) NOTE: Tracing tape should be installed per contract documents

- High Density Polyethylene (HDPE) Class 200: Tracing tape should be installed per contract

documents

Piping fittings and joints shall be restricted to the following methods:

- Welding

- Mechanical fittings

- Rolled Groove

- Threaded (flanged)

NOTE: Meg-A-Lug or similar type mechanical fittings shall not be used unless thrust blocks are

also used. GRC shall be contacted during design phase if such fittings shall be used

- Thermal Fusion (Butt) Welding: Used only for HDPE pipe installation

Standard 105 16

Non Metallic Pipe and Fittings:

All nonmetallic pipes shall be FM approved and Class 200 pressure rated. PVC pipe shall only be

coupled using mechanical joints. HDPE pipe can be joined using butt welding, mechanical joints or

“push on” bell and spigot.

All butt welding operations shall be conducted by trained and certified personnel.

Metallic Pipe and Fittings:

Schedule 10 and schedule 40 metallic pipes, for use in sprinkler systems, shall be UL or FM approved.

All pipes 6 inches and smaller (internal diameter) must have a MIC coating applied by the Mill. Eight

inch pipes and larger shall be schedule 10 MIC coated on special order from the Mill. A letter from the

Mill stating that the pipe has MIC coating is required from the contractor. This letter shall be submitted

to ME and as part of the plan review to GRC.

If the pipe is painted in the field or shop, the pipe id markings are not legible. In this case the Chrysler

ME Project Engineer or a member of Corporate must accept the pipe prior to painting.

Galvanized coated pipe is not acceptable for use in wet systems as an alternative to MIC coated pipe.

5.2.1 Cathodic Protection

If stray currents are suspected in the soil, all joints shall be bonded with low-resistance metallic ground

connections. A corrosion engineer/consultant is required to provide information on the corrosiveness of

the soil. NOTE: It maybe more cost-effective to just provide cathodic protection.

Methods, if required, for cathodic protection shall be sacrificial nuts, bituminous wrapping and coating,

or a combination of the above. A minimum of two sacrificial zinc anode nuts per connection is required.

Standard 105 17

5.3 Thrust Blocks, Piping Anchoring & Trench Backfill

Pipe anchoring is required to prevent joints from separating at bends, tees, plugs, and changes in pipe

diameter and hydrants due to unbalanced thrust created by water flow. Pipe anchoring is provided by

either using thrust blocks, rods and clamps, or locked mechanical fittings. No Meg-A-Lug (or similar

type) fittings shall be installed without thrust blocks. GRC shall be contacted during design phase if such

fittings shall be used.

Thrust blocks are constructed of concrete and are cast-in-place. Sizes are determined by code. See NFPA

13 and 24. An acceptable method (sheet metal, cinder blocks or plywood) shall be utilized to separate

adjacent thrust blocks when valves or hydrants are in close proximity to each other.

Any deviation from the above paragraphs, or other pipe anchoring methods, shall be referred to GRC

prior to submittal of plans for review.

The fire protection underground main installer or the Site General Contractor is responsible to

photograph all poured thrust blocks and to number them according to a plot plan of the site with all

hydrants, tees, valves etc labeled (these would be points where thrust blocks will be poured. As the job

progresses these photos shall be reviewed by a member of Corporate. These printed photos shall be left

on the job site in the Construction or ME trailer.

An alternative is to leave all thrust blocks uncovered for viewing by a member of the Corporate and/or

GRC.

When using HDPE underground piping follow the manufacturer’s instruction.

Standard 105 18

Underground Fire Line Pipe Trench and Bury

The minimum clear width of the fire underground main trench shall be one foot greater than the outside

diameter of the pipe. The maximum clear width of the trench shall not be greater than the pipe outside

diameter plus 2 feet.

The depth of the trench is based on surface loads and frost penetration. A minimum of 24 inch depth of

cover is required when frost is not a factor. Where frost is an issue then the pipe shall be buried 12 inches

below the recommended NFPA frost bury. The depth of cover shall be measured from the top of pipe to

finished grade.

The trench bottom shall be smooth and free from stones greater than 1 inch in diameter. Provide a

minimum 4 inch bottom cushion of stone (A6) or Class 2 sand for the pipe to rest on. ME Site

Representative or on site Testing Engineering Company must be consulted to determine if stone or sand

will be utilized for cushion and trench backfill.

If the soil is loamy or sandy A6 stone shall be used as the cushion and backfill material. A6 stone to be

used must meet the ASTM D448 requirements for a Standard size A67 aggregate size. This is basically a

mechanically crushed limestone with particle size not over 1 inch in diameter and minimum size of 3/8

inch. If the soil is clay then Class 2 sand may be used.

The cushion and backfill material shall be approved by ME Site Representative and be reviewed by

Corporate member prior to trench backfilling

5.4 Flushing of Underground Connections

All underground supply mains and lead-in connections shall be flushed to remove foreign materials

before connection is made to sprinkler piping. Flushing shall continue for a minimum of ten (10)

minutes. After ten (10) minutes, if the water is still not clear, continue flushing until water is clear. Care

shall be exercised during the flushing operation to assure that water flow will adequately drain without

producing damage to surroundings. Corporate shall be notified at least one week prior to the start of any

flushing. Representatives from Corporate and GRC must be present for all flushing.

Standard 105 19

installed at the lowest elevation of the system or portion of the system being tested. Gauge(s) used shall

be approved by member of Corporate and GRC.

No visible leakage shall be noted from the sprinkler piping. The amount of leakage for underground

piping shall not exceed two quarts (1.89 liters) per hour per 100 gaskets or joints. This permissible

leakage is not respective of (not directly proportional to) pipe diameter. The amount of leakage shall be

measured by pumping from a calibrated container to maintain required pressure during the two (2) hour

test. The amount of allowable leakage for valves is one fluid ounce per inch valve diameter per hour (30

milliliters) for each valve isolating the tested pipe section.

Hydrostatic testing of underground piping shall be performed before the trench is completely back-filled.

Piping shall be covered between joints to hold the piping in place. Joints, however, shall be left un-

covered so they can be observed for leakage during the test. When test “blanks” are used to isolate a

portion of the system, only self-indicating types shall be used. Each blank, if used, shall be inventoried

so that they can be totally removed from the system upon completion of testing.

Corporate shall be notified at least one week prior to the start of any hydrostatic testing. A representative

of Corporate and/or GRC or an approved representative must be present for all hydrostatic testing.

Upon buy off of a system all associated water supply control valves shall be identified, locked and

added to the Plant control valve inspection form.

Sprinkler installations involving 20 sprinklers or less are not required to be hydrostatically tested or

submitted to GRC for approval.

- Double Check Valve Assembly

- Check Valve

- Detector Check Valve

A low suction pressure regulating valve may be required by the local authority having jurisdiction (AHJ)

to prevent flowing water that will cause the residual pressure to drop below a predetermined rate, usually

20 PSI. These valves are not really backflow preventers.

Backflow preventers shall be FM approved. Install the backflow preventer, if required by the local AHJ,

on the discharge side of the fire pump. The local AHJ may require the backflow preventer to be installed

on the suction side of the pump.

Pressure loss of the backflow preventer shall be incorporated into the sprinkler system design hydraulics.

All devices shall be located above ground.

Standard 105 23

First Main Pump 130 Manual Off

Second Main Pump 120 Manual Off

Any deviations from these settings shall be approved by Corporate and GRC.

If the facility is equipped with both a Diesel and Electric main fire pump driver the Diesel shall be

the first to start. NOTE: Corporate and GRC may vary this requirement based upon an analysis of

“churn” pressure and discharge of water from pressure relief valves. (See attached chart on fire pump

piping criteria)

Standard 105 25

6.4 Jockey (Pressure Maintenance) Pump

Jockey pumps are provided to maintain pressure in fire protection water supply systems that have a fire

pump. A jockey pump operates to maintain pressure in the water supply system and prevents excessive

“wear” on fire pump(s).

Jockey pumps shall be listed by Underwriters Laboratories (U.L.).

Jockey pumps shall have a rated capacity sufficient to meet the demands of the water supply system.

Jockey pumps shall be selected to make up the allowable leakage rate in 10 minutes or 1 gpm (3.8

L/min), whichever is larger.

consultation with Corporate Fire Prevention Engineer and GRC.

Standard 105 27

7.0 Roof Decks

7.1 General

Roof decks shall be minimum Class I-90 insulated steel deck for wind uplift (PSF) and FM Class 1 for

flame spread. If an insulated roof deck other than I-90 is specified contact Corporate and GRC

FM Global approves a number of special roof insulation and roofing “systems”. These systems are used

to provide components of the roof deck, including vapor barriers, insulation, wind up-lift resistance and

adhering material that provides fire safety and wind resistance.

The FM Approval Guide and Data Sheet 1-28 and 1-29 shall be reviewed when considering types of roof

deck for an installation. Items such as ground roughness and distance from a coastline shall be

considered in determining the type of roof system.

Approved proprietary roofing systems and components shall be provided in accordance with the Factory

Mutual Approval Guide.

All thermal barrier boards, including gypsum board, shall be fastened in accordance with FM Data Sheet

1-29.

7.2 Roof Coverings

Roof covering range from combustible wood shingles with no fire retardant treatment to coverings that

are effective against severe external fire exposure. Well-designed fire resistive roof coverings can

minimize the likelihood of fire spread from one building to another.

7.2.1 Roof Covering Classifications - Factory Mutual Global

An insulated steel deck roof is designated FM Class 1 when the roof is constructed with deck

components that have met Factory Mutual Global limitations on heat release rate during testing.

When heat release from a tested roof assembly exceeds those limitations, the roof is designated FM Class

2.

7.2.2. Roof Covering Classification - NFPA

Three classes of fire resistive roof coverings in accordance with NFPA are as follows:

Class Coverings: Include roof coverings that are effective against severe fire exposures. These coverings

are not readily flammable, do not “carry” or communicate fire, have a high degree of fire protection to

the roof deck, do not slip from position and possess no flying brand hazard. They do not require frequent

repairs to maintain their fire retardant properties.

Class B Coverings: Include roof coverings that are effective against moderate fire exposures. These

coverings are not readily flammable, do not readily “carry” or communicate fire, have a moderate degree

of fire protection to the roof deck, do not slip from position and possess no flying brand hazard. They

may require repairs to maintain their fire retardant properties.

Class C Coverings: Include roof coverings that are effective against minimal fire exposure. These

coverings are not readily flammable, do not readily “carry” or communicate fire, have a slight degree of

fire protection to the roof decks, do not slip from position and possess no flying brand hazard. They

require repairs or renewals to maintain their fire retardant properties.

Building codes commonly require Class “A” or “B” coverings wherever fire resistive construction is

required or within requirements of local codes. Class “C” roofing is appropriate for other buildings.

Many municipalities specify Class “C” as the minimum standard for roofing.

Standard 105 28

Chrysler Group LLC will only accept Class “A” roof covering installations and Factory Mutual

Class 1 approved roofing systems unless deviations are approved by Corporate and GRC.

7.3 Construction

Insulated steel deck is constructed by first securing rigid insulation board to the upper surfaces of the

deck with insulation fasteners. A waterproof covering is then installed above the insulation. The built-up

roofing type is three to five piles of roofing felts adhered to the insulation and to each other with hot tar

or asphalt.

The single-ply membrane covering is also widely used. The ply is fastened to the deck and adhered to

the insulation or loosely laid and covered with stone ballast.

When a vapor barrier or retardant is needed, this single ply sheet can be placed directly on the deck, or in

some cases. Adhered to a minimum thickness insulation board mechanically fastened to the deck.

Steel decks roofs shall have slight slopes to permit water run-off and to prevent puddles from forming.

Any roof decks not covered in the above sections shall be referred to the Corporate Fire Prevention

Engineer for approval and comments such as standing seam, single ply membrane etc.

7.4 Standing Seam Roof Systems

This system is used in pre-engineered building structures. The roof system must meet all FM criteria.

Standard 105 29

8.0 Fire Walls & Partitions

8.1 General

Firewalls are interior walls that provide a fire separation between areas of the same building. Firewalls

are designed to prevent the spread of fire into or within a building, and to assure that the barrier will not

collapse during fire exposure. Firewalls shall be designed to maintain structural integrity to the extent

that collapse of the structure on either side of the firewall will not cause the wall to collapse. To

withstand heat expansion effects, firewalls are commonly made thicker than would be required by normal

fire resistance ratings. Walls may be buttressed by cross walls or pilasters if of considerable height or

length. Fire resistance ratings for firewalls range from three to six hours.

Fire partitions subdivide a floor or building area and extend from the floor to the underside of the floor

above. Fire partitions may be constructed of non-combustible, limited combustible or protected

combustible material and shall be attached to and supported by structural members having fire resistance

at least equal to the requirement of the partition. A fire partition normally possesses less fire resistance

than a firewall and does not extend from the basement through the roof, as does a firewall. Fire

resistance ratings for partitions range from one-half to two hours.

Fire walls and partitions are commonly constructed of masonry, wood or metal studs using fire resistive

materials.

Exterior walls, interior partitions and floor/ceiling assemblies are components that define the

architectural layout of rooms in a building. These components are used to provide privacy, security, and

protection from the elements and noise control. They also provide fire protection by delaying or

preventing fire from spreading from one room to an adjacent room. IF THESE WALLS HAVE

URETHANE FOAM INSULATION AND ARE OVER 30 FEET HIGH THEN THEY MUST BE

FACTORY MUTUAL GLOBEL APPROVED. THIS REQUIREMENT IS FOR EXTERIOR

AND INTERIOR WALLS.

The effectiveness of a barrier in preventing flames from moving from one room to another depends upon

the fire resistant construction of the barrier, the fuel load in the room, applied loading on the structural

components, the construction features and the effect of openings and penetrations in the barrier.

The most common cause of fire movement from one room to an adjacent room is through unprotected

openings in barriers. Code requirements and heavy duty construction are often rendered ineffective

because of uncontrolled openings in a partition, i.e., doors, windows, grilles, ducts, and other openings in

conjunction with a lack of protection of openings.

Fire doors shall be UL listed or FM approved. NOTE: ULC in Canada.

All exterior metal foam (sandwich) panel walls shall be Factory Mutual approved when used for walls

over 30 feet in height

8.2 Fire Resistance

Building codes, through construction classification, identify fire resistive requirements of barriers.

Fire resistance ratings are determined by subjecting the barrier assembly to standard fire tests. Fire

resistance is the endurance time converted to duration in hours that is established by recognized

standards. Both combustible and non-combustible barriers can obtain fire resistance ratings from fire

tests. Fire doors and other protected openings shall have a fire resistance rating equal to or exceeding the

rating of the wall (partition).

Fire resistance of walls and partitions will delay or prevent flames from moving horizontally from one

room to an adjacent room. These assemblies are tested in accordance with NFPA #251, “Fire tests for

Building Construction and Materials”.

Standard 105 30

Large manufacturing and warehouse buildings are sub-divided into fire areas to limit the spread of fire.

Horizontal fire spread is limited by distance between building (as required by code) or by firewalls.

In multi-story buildings, vertical fire spread from one story to another is limited by the floor construction

and by wall enclosures around stairways, elevator shafts and other horizontal and vertical openings.

8.3 Application

Subdivision of a building through use of barriers is intended to independently limit property loss from a

single fire. However, fire suppression systems supplement passive barriers to provide an adequate fire

protection system. If sprinkler protection is impaired, reliance must be placed on passive barriers and

manual fire fighting operations for fire containment.

Area housing hazardous processes, equipment or materials shall be isolated from surrounding

occupancies. Paint mix rooms and paint operations shall be separated from metalworking operations and

other fuel and heat sources, flammable-liquid storage tanks from main-plant buildings, and storage from

manufacturing operations. Equipment or services of vital importance to uninterrupted production shall

also be separated from the fire or explosion hazards of surrounding buildings or occupancies. Power-

generation equipment shall be located in a segregated building. Power transformers and switchboards

shall be located in fire-resistive cutoff rooms or located outside. Storage of records and tracings shall be

in special vaults.

8.4 Parapets

Parapets prevent passage of fire over firewalls when the roof deck is combustible. Parapets shall extend

at least 30 inches above a combustible roof and shall be of non-combustible construction. Parapets shall

be an extension of the firewall, designed to break the continuity of embers and radiant heat from

spreading to an adjacent fire area. Class I insulated metal roof decks are not sufficiently combustible to

require parapets.

Standard 105 31

9.0 Smoke & Heat Venting

9.1 General

Ventilation is the planned and systematic removal of heat, smoke, and fire gases from a building.

Ventilation may be required in accordance with rescue efforts in order to protect occupants from smoke

and heat and to provide visibility and tenability during rescue operations.

Emergency exhaust (heat & smoke) vents shall be provided in storage areas and other high heat release

areas only when required by local codes and the AHJ.

Corporate and GRC do not required smoke and heat venting unless required by local AHJ.

Emergency exhaust wall vents shall be provided in conjunction with, but not in place of, fire rated walls

and fire detection and suppression systems.

Vents, where required, shall operate both automatically and mechanically. Automatically operated vents

shall be connected to the building/plant security system and designed to operate upon activation of the

fire alarm system or sprinkler system within that zone.

Vents shall be equipped to operate mechanically by provision of a fusible link. This link shall be one

temperature rating higher than the existing sprinklers in the area. For example, if sprinklers are 286°F,

use 360°F fusible links for heat and smoke vents.

Heat and smoke venting shall be provided at a ratio of 1 square foot per 30 square feet of room floor area

(1:30) or as required by local codes.

A powered exhaust option for up to 50 percent of required heat and smoke venting may be provided at a

ratio of 300 cubic feet per minute of exhaust volume per square foot of heat and smoke venting (300:1).

Dampers and smoke detectors shall be installed in ductwork/stacks in accordance with the Authority

Having Jurisdiction.

9.2 Vent Types

Heat and smoke vents are typically 16 to 100 square feet in area. Automatic vent operation is of two

types, i.e., fusible link type or “drop out” plastic. The fusible link type consists of a metal housing with

lids that depend upon a temperature rated fusible link to trip the lid mechanism. The drop out plastic

type depends upon a temperature sensitive, transparent or translucent thermoplastic dome that deforms

from its setting and falls out of the roof when heated beyond its temperature rating. Vents designated for

manual operation (in conjunction with automatic operation) are constructed with metal lids to resist

elevated fire temperatures and may be opened from the floor with wires and cables.

9.3 Explosion Relief Venting

Explosion relief venting (for the Paint Mix Room only) shall be provided at a ratio of 1 square foot per

50 cubic feet of volume (1:50). Explosion relief venting can be designed into either the roof or wall.

Explosion relief venting shall relieve at 20-25 pounds per square foot, but in no case less than the design

wind load pressure.

Explosion resistance shall be 100-125 pounds per square foot, but in no case less than five times the vent

release pressure.

Standard 105 32

9.4 Draft Curtains

Only in large buildings that are not sub-divided by walls or partitions, draft curtains are important for

prompt and positive actuation of vents because they bank up heat within the curtained area and limit the

spread of heat and smoke to the zone or area of fire origin.

Draft curtains are constructed of any substantial non-combustible material that will resist the passage of

smoke. Draft curtains are required only if needed due to local codes or in conjunction with ESFR

sprinkler heads.

The depth of draft curtains should be selected to correspond with the design depth of the smoke layer.

As a guideline curtain depth should not be less than 20% of the ceiling height to prevent spillage of

smoke under the curtain. Draft curtains used in conjunction with ESFR sprinklers only need to be 2 feet

deep.

The distance between draft curtains shall not exceed eight times the ceiling height so that smoke control

and actuation of roof vents within the curtained compartment will be effective. The distance between

draft curtains shall be not less than two times the ceiling height, unless the draft curtains extend to a

depth of at least 40% of the ceiling height.

Standard 105 33

10.0 Sprinkler System Requirements

10.1 Classification of Occupancy

The function (use) of a building as directed by the building code and the authority having jurisdiction is

the determining criteria for designing a sprinkler system as the system must be designed to protect against

the hazards inherent to the type of occupancy. Three main classes of occupancy are recognized in

accordance with NFPA. Sprinkler discharge densities, water supply requirements, spacing of sprinklers

and schedules of pipe sizes (if a pipe schedule is used) differ for each hazard.

The three main classifications of occupancy are light hazard, ordinary hazard, and extra hazard as

follows:

Light Hazard: Includes occupancies where the quantity and combustibility of material is low, and fires

with relatively low rates of heat release are expected. This class includes office buildings and computer

facilities.

Ordinary Hazard: This class includes ordinary mercantile, manufacturing and industrial properties. This

call is divided into two groups:

- Group I includes occupancies or portions of other occupancies where the combustibility is low,

quantity of combustibles is moderate, stockpiles of combustibles do not exceed 8 feet (2.4

meters), and fires with moderate rates of heat release are expected.

- Group II includes occupancies or portions of other occupancies where quantity and

combustibility of contents is moderate to high, stockpiles do not exceed 12 feet (3.7 meters),

and fires with moderate to high rates of heat release are expected.

- Extra Hazard: This class includes occupancies or portions of occupancies where quantity and

combustibility of contents is very high and flammable and combustible liquids, dust, lint, or

other materials are present, introducing the probability of rapidly developing fires with high

rates of heat release. Extra hazard occupancies involve a wide range of variables that produce

severe fires. The following shall be used to evaluate the severity of Extra Hazard (E. H.)

Occupancies.

- Group I involves an E. H. occupancy with little or no flammable or combustible liquids.

- Group II involves an E. H. occupancy with moderate to substantial amounts of flammable or

combustible liquids or where shielding of combustibles is extensive.

Examples of Ordinary Hazard Group I occupancies are automotive parking garages, electronic plants,

laundries, etc.

Example of Ordinary Hazard Group II occupancies are machine shops, metal working, repair garages,

wood machining, tire manufacturing, etc.

Examples of Extra Hazard Group I occupancies are some aircraft hangars, die casting, upholstering with

plastic foam, rubber reclaiming, printing with inks with flash points below 100°F, etc.

Examples of Extra Hazard Group II occupancies are flammable liquid spraying, flow coating, open oil

quenching, plastic processing, varnish & paint dipping, etc.

While classification of occupancies into three broad categories serves as a basic guide, each individual

area of occupancy (hazard) shall be evaluated, as it may be more severe than the criteria with which the

building sprinkler system is designed, thus requiring review and up-grade of the fire protection system.

In each of the three building classifications, the system may be either follow an appropriate piping

schedule or the system may be hydraulically calculated. Hydraulically calculated systems are required on

all new Chrysler Group LLC facilities/buildings and are preferable for renovated facilities.

Maximum coverage area per sprinkler head is 130 sq. feet and maximum length on the branch line

between heads is 15 ft.

Sprinkler design criteria for buildings over 30 feet in height must be established by Chrysler Group LLC

Corporate Fire Prevention Engineer and Loss Prevention Service Provider GRC.

Ductwork shall be designed for a minimum of 30-gpm for the most remote 10 sprinklers. Sprinkler

protection is required in ductwork 100 square inches of cross-sectional in rectangular or square area and

above whenever the ducts are combustible, handle solvent laden air, is a pathway for combustible dusts

or particulate matter or where combustible residues can collect on the ductwork interior. Round ductwork

10” in diameter and larger requires sprinkler protection. Maximum spacing between sprinkler heads shall

be 10ft.

Contractor shall use 1.4 times the square foot of the most remote area for the length of the remote branch

line.

NOTE: Use 100-psi as maximum design pressure at the base of riser for any sprinkler system. For office

occupancies, this maximum design pressure may be increased to 110-psi with approval obtained from the

Corporate Fire Prevention Engineer.

This is acceptable based upon:

a). Design criteria shall remain as 0.80-gpm per square foot over most remote 2,000 square feet plus

500-gpm hose stream allowance.

b). Additionally the design criteria shall be proven to ensure systems can deliver 1.0-gpm per square

foot over the most remote four sprinklers within a minimum end head pressure of 25-psi for this criteria.

c). Sprinkler spacing shall be limited to maximum 150 square feet per sprinkler and minimum 100

square feet per sprinkler coverage. Layout should be designed to be a square pattern or as close to a

square as possible with maximum distance between sprinklers being 12.5 feet and minimum 10 feet.

d). Design calculations for remote area shall use the 1.4 shaping design for number of heads flowing in

remote area.

e). Use 165°F or 212°F (temperature) rated sprinklers.

f). Installation must be in accordance with manufacturer's listing requirements and NFPA #13 including

all obstruction rules (including pipe shadow) but pipe hangers shall meet ME pipe hanger standard.

g). There must be a minimum three foot ceiling level partition between systems using EC-25 sprinklers

and adjacent sprinkler systems that do not have EC-25 sprinklers i.e., standard response sprinklers.

h). Storage of exposed plastic components and containers shall be limited to 20 feet in a 35 foot

building. Any storage racks shall be open frame with wire mesh shelves or no shelves. Solid and

slatted shelves are not accepted unless in-rack sprinklers are installed.

10.3 Sprinkler Heads (see table)

Sprinkler head type (upright or pendent) should be determined in conjunction with the room design

parameters.

Early Suppression/Fast response (ESFR) sprinklers are becoming a widely used concept in moderate and

high hazard environments and are acceptable for use within Chrysler Group LLC facilities/buildings.

ESFR sprinklers have an extra large orifice and deflector and are designed to produce larger water drops

that quickly pierce a rapidly developing fire, particularly rack storage facilities. ESFR sprinklers also

have a sensitive fusible element that provides fast response to heat. Installations involving ESFR

sprinklers must follow the guidelines within Factory Mutual Data Sheet 2-2 and NFPA #13, latest

editions.

Guidelines for ESFR sprinkler applications shall be found in the latest version of FM Global Data Sheet

2-2 and NFPA #13, latest editions. General guidelines shall be as follows:

Building height - 40 feet or less (roof slope with maximum 2 inches per foot)

Storage height - 35 feet or less

Type of Storage - Rack or Pallets

Not allowed with occupancies involving hydraulic oil under pressure

Chrysler Security Services and GRC shall be consulted before specifying the use of ESFR sprinklers

Standard 105 37

NOTE: There is now an ESFR sprinkler with a K-factor of 25. Presently it is not approved for the

storage of exposed, unexpanded nor expanded plastic storage.

FM Global and NFPA have cancelled as of May 2001 the 45 foot allowance for K-14 and K-16.8 ESFR

sprinklers. They will no longer permit the use of K-14 and K-16.8 ESFR sprinklers for palletized storage

up to 35 feet under a ceiling/roof height up to 45 feet. They will now require one level of in-rack

sprinklers to protect the above storage scenario.

Sidewall sprinkler heads shall not be considered for use in accordance with this Standard.

Sprinklers can be concealed, semi-recessed, or surface mounted design for finished ceiling areas. For

unfinished ceiling areas, sprinklers are exposed in the pendent or up-right position.

FM Global approved Extra Large Orifice (ELO) can be used in lieu of standard orifice sprinkler heads if

approved by GRC. ELO sprinklers are not the same as neither Large Drop nor ESFR sprinklers. ELO

sprinklers have the same nominal K-factor as Large Drop sprinklers but they are not the same and can not

be interchanged.

Before Large Drop sprinklers are recommended, an analysis is required to ensure the model and

manufacturer are approved for the specific application.

All sprinklers that are susceptible to being coated with paint or other foreign materials shall be protected

by an approved method.

Bags over sprinklers - 0.003-inch (0.076 mm) cellophane secured with a rubber band or zip tie.

Sprinkler heads shall be covered with protective cellophane bags (available from Corporate).

Bags shall be attached to the sprinkler head base using zip ties or rubber bands. Zip ties and rubber bands

shall be placed so that they do not interfere with the sprinkler head discharge. Tape is not an acceptable

method for securing the bags.

14.3.2.1 Carbon Dioxide Protection

Carbon Dioxide Fire Protection System Minimum Requirements

Scope:

This section contains minimum requirements for carbon dioxide fire protection systems. It includes only

the basic essentials to make the standard workable in the hands of those trained & skilled in this field.

Only those with the proper training and experience shall design, install, inspect, and maintain this

equipment. Examples of proper training would be factory certification by a particular system

manufacturer.

The entire system shall comply with the most current edition of NFPA #12 and this Standard.

Systems:

Two major types of carbon dioxide systems are used at Chrysler Group LLC facilities – Total Flooding

systems and Local Application systems.

Total Flooding System – consists of a fixed supply of carbon dioxide normally connected to fixed piping

with nozzles arranged to discharge carbon dioxide into an enclosed space or enclosed space around the

hazard.

Local Application System - consists of a fixed supply of carbon dioxide normally connected to fixed

piping with nozzles arranged to discharge carbon dioxide directly on the burning materials.

Agent Storage Containers:

Carbon dioxide extinguishing systems use either high-pressure storage units (cylinders at room

temperature usually in 75 or 100 lb. capacity for industrial applications) or low pressure storage units

(large refrigerated tanks – ¾ ton or larger). Ansul’s Mini-bulk low-pressure system range from 500-lb. to

1,500-lb. Capacity and are considered low- pressure systems.

System storage container selection is primarily based upon economics that is strongly influenced by

hardware requirements. Typically, selecting a low-pressure storage container becomes more favorable as

system carbon dioxide requirement increase. Multiple timed discharges are also possible with low-

pressure storage containers.

High Pressure – Indicates that the carbon dioxide is stored in pressure containers at atmospheric

temperatures. At 70 F, the pressure in this type storage is 850 psi.

Low Pressure - Indicates that the carbon dioxide is stored in pressure containers at controlled

temperatures, at 0 F. At 0 F, the pressure in this type storage is 300 psi.

Extinguishing Mechanism:

Carbon dioxide extinguishes a fire by oxygen depletion and reducing the oxygen content from the normal

21% in air to 15%. This will extinguish most fires. The cooling effect created by a carbon dioxide

discharge is of little significance. Since it is a gas, it will penetrate and spread to all parts of a hazard.

Carbon dioxide does have a density about 50% greater than the density of air.

Standard 105 47

Applications:

Based upon Chrysler Group LLC Corporate Standards, carbon dioxide shall not be a replacement for

providing automatic sprinkler protection, unless approved by the Chrysler Group LLC Corporate Fire

Prevention engineer. A carbon dioxide fire suppression system can be used to provide supplemental fire

protection in the following areas:

Within machine enclosures, associated ductwork and oil mist collector(s) using combustible cutting

oil.

NOTE: Carbon dioxide protection can be omitted within horizontal ductwork and oil mist collector if all

three of the following conditions are met and approved by local AHJ:

1). There is a damper on all vertical ductwork interlocked to close automatically prior to discharge of the

carbon dioxide system.

2). All horizontal ductwork and oil mist collector(s) have automatic sprinkler protection. Also, the

ductwork must be designed to hold the additional weight of the sprinkler water discharge.

3). Carbon dioxide system is designed to protect the entire machine enclosure and vertical ductwork.

Within unmanned pits such as caster/camber, roll test, BSR pits, etc. (if manned pits, HFC-227ea

(FM-200) shall be used)

Within normally unmanned rooms, if approved by the Corporate Fire Prevention engineer. An

example is a dynamometer test cell.

Beneath raised floor of a data/computer room(s).

Heat-treat operations using combustible quench oil (local application).

Sequence of Operation using fixed temperature heat detectors:

Rooms (dynamometer, engine test, etc.):

Minimum two detectors

Activation of alarms within room, outside room and on Release control panel upon activation of 1st

detector.

Activation of all interlocks upon activation of 1st detector.

Discharge of carbon dioxide gas after a 30 second pneumatic time delay upon activation of 1st

detector.

Pneumatic siren or sirens

NOTE: Pneumatic time delay not required on systems protecting high hazard fires such as flammable

liquids.

Machinery Enclosure when protected is required:

Minimum two detectors

Activation of alarms on equipment and release control panel upon activation of 1st detector.

Activation of all interlocks upon activation of 2nd

detector.

Discharge of carbon dioxide gas upon activation of 2nd

detector with no time delay.

NOTE: Sequence of Operation for each protected machinery enclosures must be reviewed on a case-by-

case basis due to various factors that may apply. It is critical that contractor contact Chrysler Group LLC

Corporate Fire Prevention Engineer and GRC prior to engineering the protection so that any factors can

be reviewed prior to designing the protection.

Hazards to Personnel (Also refer to latest edition of NFPA #12):

The discharge of carbon dioxide in fire-extinguishing concentration creates serious hazards to personnel,

such as suffocation and reduced visibility during and after the discharge period. In any use of carbon

dioxide, consideration shall be given to the possibility that personnel could be trapped in or enter into an

atmosphere made hazardous by a carbon dioxide discharge. In addition to the protected space,

consideration shall also be given to the possibility of carbon dioxide drifting and settling into adjacent

places outside of the protected space. Consideration shall also be given to cylinder storage areas where

the carbon dioxide can collect in the event of a discharge from a safety relief device of a storage

container. Suitable safeguards shall be provided to ensure prompt evacuation, to prevent entry into such

Standard 105 48

atmospheres, and to provide means for prompt rescue of any trapped personnel. Personnel training shall

Standard 105 59

16.0 Fire Alarm Systems & Release control panels

For new or replaced fire alarm systems see document “A” under Standard 105 in the

FBOK

16.1 System Types

Fire protection signaling systems are classified according to the function they are expected to perform.

Types of systems are as follows:

16.1.1 Local System

The purpose of a local protective signaling system is to sound local alarm signals for evacuation of the

protected building.

The basic features of a local protective signaling system are:

- A control panel.

- A primary (main) power supply that usually is the local power service.

- A secondary (stand-by) power supply (batteries).

- Initiating devices such as detectors, manual fire alarm boxes, water-flow alarm devices, and

other alarm initiating devices.

- Signaling devices such as bells, horns, speakers or central station annunciation.

A local alarm system may not relay a signal automatically to a central station or fire department.

Therefore, when a local alarm “sounds” and the system is not connected to a central station or fire

department (typically in office buildings) personnel must notify the fire department.

The fire alarm control panel’s outer most enclosure shall have a locking mechanism (hasp) that can be

secured with a pad lock. This pad lock shall be supplied to the installing contractor by the local G4S

Secure Solutions Site Security Manager.

16.1.2 Auxiliary Systems

An auxiliary protective signaling system has circuitry connecting alarm initiating devices to the

municipal fire alarm system (fire department) either through a master fire alarm box or through a

dedicated telephone line connected directly to the municipal communication central switchboard. The

signal received by the fire department is the same received when someone manually activates any

municipal fire alarm box.




16.1.3 Remote (Central) Station Systems

A remote station signaling system has an alarm signal that is received at a remote location that is attended

by trained personnel 24 hours a day (constantly attended). The receiving equipment is located at a

facility other than the fire department, such as a police station or telephone answering service. The signal

is transmitted over a leased telephone line, and is indicated audibly and visually at the remote station.

Remote station personnel notify the fire department of the alarm.




Standard 105 60

16.1.4 Proprietary Systems

The proprietary system is a widely used type of control unit in large commercial and industrial

occupancies.

Proprietary and central station systems are similar in operation. The main difference is as follows:

The station (location) receiving the fire alarm signal in a proprietary system is operated by personnel

with a proprietary interest in the protected buildings (on-site).

Central station system is staffed by operators who perform the service for a fee and have no proprietary

interest in the protected buildings.

The proprietary system receiving station is a security office within or near the building (or group of

buildings) protected by the system.

Many existing proprietary systems have separate initiating device circuits for each building zone or

subsection, similar to the local, auxiliary, and remote station systems. With the increasing use of

electronics, proprietary systems for larger buildings have signals multiplexing and built-in computer

systems. These systems receive all signals from the building over one or more pairs of wires and

determine the exact location of a fire by use of different frequencies or digitally coded information

transmitted over the multiplex system.




16.2 Points to Alarm

Points to alarm include the following:

- Water flow switches (vane type and pressure switch)

The alarm contractor shall make the initial setting on the water flow alarms. The maximum time

for the water flow to received alarm at the proprietary or central station shall be no longer than

90 seconds.

- All water flow alarms must be able to be tested. This is accomplished by piping the alarm line to

a fixed drain or into the water wash in a paint shop. If the above is not accessible then a 5/8”

quick disconnection to accept a 5/8 inch garden type hose.

- Valves (exterior valves, SCV, PIV, Wall valves do not require tamper switches. A means to

lock the valves shall be supplied. Lock NPN code 35-610-0864

- Detectors (smoke, heat, flame)

- Manual pull stations

Fire Pumps - NOTE: P = Alarm at control panel F = Alarm received at remote location

- Fire pump running (started) = F

- Switch off Automatic = F

- Loss of operating electric power = P

- Phase reversal on line side of the motor = P

- Low fuel supply = P provide a low fuel switch to alarm at the 5/8 level of the diesel

fuel tank

- Controller main switch in “off” or “manual” position = F

- Low lubricating oil pressure = P

- High engine temperature = P

- Battery charger failure = P

- Overspeed= P

- Low pump house temperature (42 oF) = P

- Suction supply water level below normal = P

- Suction supply water low tank temperature (42oF ) = P

If these alarms have a common audible signal, each condition shall be visually shown (individually) at

the fire pump use controller, and at the Plant’s Proprietary Alarm Panel.

Standard 105 61

- Special Suppression Systems

- Discharge of Agent

- System trouble

Fire alarm systems provide several distinct types of audible signals as follows:

- Trouble Signal - A “trouble signal” is given when a fault occurs in a supervised (monitored)

device or circuit of a protective signaling system. Circuits that are normally supervised included

main power, alarm initiating and alarm signaling circuits. Trouble signals for remote station

auxiliary systems are received at a central supervisory station. In local and proprietary systems,

trouble signals are “sounded” in areas where personnel are normally present.

- Supervisory Signal - In sprinkled occupancies, a sprinkler “supervisory signal” is given when a

critical component in the sprinkler system is in an abnormal condition. These conditions

include such factors as low water service pressure, loss of power to a fire pump, closing of a

water supply valve, low water level of a water supply tank, or near freezing temperature in an

outdoor water supply tank. Local and proprietary system supervisory signals are usually

“sounded” in areas where personnel are normally present. Remote station and auxiliary system

supervisory signals are received at the receiving station.

- Alarm Signal - When a fire is detected, an alarm signal is transmitted upon operation of either a

manual or automatic initiating device (manual pull station, suppression system, or detector).

Although alarm signals generally involve the sounding of audible signals throughout a building,

signals may be “sounded” only in the vicinity of the immediate fire area of large buildings. The

alarm signal may be a taped or live voice message broadcast over a fire alarm speaker system.

These signals are either coded or un-coded as follows:

- Non-coded Signal - Alarm signals produced by a fire alarm system may be continuous sounding

throughout the protected area. When these devices are “sounded” continuously, the system is

“non-coded”.

- Coded Signal - When devices are sounded intermittently in a prescribed pattern, the system is

referred to as a “coded” system. Coded signal systems vary in size, depending upon the size and

needs of the alarm system.

Signals can be audible or audible/visible.

Because public buildings must be accessible to handicapped people, fire alarm system must include

visual alarm signals to alert occupants with impaired hearing and in high noise areas by use of a

combination horn/light unit. (Refer to American with Disabilities Act guidelines)

The fire alarm system shall comply with requirements of the latest edition of NFPA Standard #72 for

Protected Premises Signaling Systems. The system shall be electrically supervised Class ‘A’ Style 6 and

monitor the integrity of all conductors.

The system contractor/supplier is responsible for programming (reprogramming) all points at the head

end. The point descriptor shall be obtained from the local Wakenhut (G4S) Site Security Manager.

Special suppression systems shall send a signal to the head end on the 1st alarm signal. This signal shall

be received as an “alarm” point and not a “trouble” signal.

Standard 105 62

16.3 Evacuation Systems

For new or replaced evacuation systems see document “B” under Standard 105 in the FBOK

Evacuations tomes shall have a sound level at least 15 dB above the ambient sound level or 5 dB above

the maximum sound level having a duration of at least 60 seconds whichever is greater, measured 5 feet

above the floor. The sound level shall not exceed 115 dB.

Emergency evacuation systems shall be capable of producing three distinct tones:

Fire/evacuation – Provide three (3) 0.5 seconds tones spaced 0.5 seconds apart followed by a

1.5 second pause. This pattern must be repeated for at least three (3) minutes.

Take cover/seek shelter – Provide a continuous bi-tone (high/low) oscillation for at least three

(3) minutes.

All clear/recall – Provide a continuous signal-tone for at least one (1) minute.

Shelter in place – Ability to provide a 4th

tone is required for any new evacuation system. The

tone pattern will be determined once NFPA 72 is revised to require this 4th

tone.

All tones must be manually selectable form the head end. These tones must be distinct and not used for

any other plant signaling systems. The only acceptable method for multiple tones is to use speakers and

not horns for the evacuation system.

The evacuation system's software shall be programmed such that if communication between a field panel

and the head end is lost, the field panels while going into the “degrade” mode DOES NOT activate the

evacuation alarm if a signal is received at the "degraded" panel.

In response to this loss of communication, local Plant Security is required to send a person to monitor the

"degraded" panel until repairs have been made and or communications is reestablished with the head end.

This procedure shall be followed when working with a "Class B" system. If the system is a style 6 (or 7)

or "Class A" system, then the loss of communication is recorded, but the network panels will continue to

function. Alarms can still be received and acknowledged from the panel in the security console room.

Repairs shall be made as soon as possible to the system as required.

Exposed wiring for speakers as well as any amplifier boxes must be run in rigid conduit from the device

up to the bottom chord of ceiling truss. Wiring may then run in bridle rings or cable trays such that there

is nor sagging below the bottom cord of the truss. The distance between bridle rings shall not exceed 10

feet. In office area exposed wire shall be run in IMT up to the suspended ceiling.

Testing of the completed system shall be done with representatives from Plant Engineering, local Plant

Security and Corporate. The local authority having jurisdiction (AHJ) involvement shall be determined

on a plant by plant basis by local Plant Management. A sound meter shall be utilized for all speaker

testing.

16.4 Fire Release Panels

The following is a basic description of release control panels (RCP) acceptable for use at Chrysler Group

LLC facilities for the release of a fire suppression agent such as HFC-227ea (FM-200), HFC-125

(ECARO), Pro-inert or carbon dioxide, , dry chemical, high-speed deluge, etc. NOTE: Since these

panels can be used to activate a fire alarm, the manufacturer commonly refers to these as Fire Alarm

Control Panels (FACP). When used to release a fire suppression agent as well as activate a fire alarm,

refer to the given panel as a release control panel and the panel used to activate the building fire alarm

(evacuation) system as the fire alarm control panel. At a given facility, several RCPs may be connected

to one FACP.

Standard 105 63

The release control panel is only one component of the entire fire suppression system. The name of the

given panel or the manufacturer is generally used to describe the entire system. It takes several

devices/components to makeup a fixed fire suppression (protection) system. These include such devices

as manual pulls, smoke detectors, heat detectors, flame detector, strobes, horns, speakers, modules,

relays, cable, conduit, extinguishing agent, cylinders, tanks, batteries, etc.

Normally the release control panel is located within a large painted red NEMA 12 cabinet/enclosure that

also contains various relays, modules, switches, batteries, power supply, battery charger, wiring, etc. This

panel must be located outside the protected space.

The release control panel’s outer most enclosure shall have a locking mechanism (hasp) that can be



The release control panel contains the CPU (microprocessor).Addressable Release control

panels have a keypad that can be used to program the panel.

Release control panels contains relays and terminal blocks used to attach wires connected to the power

supply, Notification Alarm Circuits (NAC), Initiating Device Circuits (IDC), and Signaling Line

Circuit(s), etc. The RCP contains and executes all control-by-event programs for specific action due to

detection of a fire. It stores all the system’s operational parameters (programmed) in non-volatile

memory (different from the history memory (buffer)). The RCP contains the real clock for the date and

time used for the history memory to display and print “alarm” and “trouble” events.

The following are two sections from Chrysler Group LLC - Corporate Fire Protection Standard #101.

The releasing control panel shall be UL listed and Factory Mutual approved, per panels listed in Section

4.4 or Chrysler Group LLC approved equal. The control panel shall provide power for all fire sensors

with twenty-four (24) hour battery backup. The control panel shall have the following features:

- The control panel shall be capable of linking up to a minimum of one hundred

twenty-seven (127) addressable devices per circuits.

- The control panel shall provide a separate custom thirty-two (32) character

message for each addressable device.

- The control panel shall provide a non-volatile memory that retains all alarms

or trouble conditions in the event both primary and secondary power is lost. Memory shall be

accessible through use of an IBM Compatible Personal Computer.

The control panel shall be field programmable using an IBM Personal Computer without reprogramming

of computer chips or by other means.

Electrical conduits shall only enter fire release control cabinets/enclosures from the side.

Penetrations to the fire release control cabinet enclosure shall only be performed by the fire

release control panel installer or under their supervision.

A smoke detector is not required over the release control panel as Chrysler has determined that this panel

is not part of the building fire alarm system. However, if the AHJ requires this detector, then it shall be

wired (separate address) to the building fire alarm system, and not the release control panel.

Standard 105 64

16.5 Proprietary Products

The following products shall be exclusively used for their respective services in accordance with this

Standard:

Equipment Manufacturer

Fire Alarm &

Evacuation Systems Siemens, Notifier and Simplex/Grinnell

Cla-Valve

Model 7100KH Cla-Val Company

Bete Nozzle

TF Series Bete Fog Nozzles, Inc.

IR3 Detector

X-3301A21W1 Detector Electronics/Detronics (Preferred Unit)

Cheetah/Cheetah Xi Fike Corporation

Some definitions are in order to explain the differences in Release control panels and fixed fire suppression

systems.

Addressable release control panel: A release control panel that has the ability to display the

programmed address (name) of the device or devices that have been activated due to a fire condition,

manual action, or electrical “short” or “open”, etc. Each device associated with the system is assigned an

address (name) which when programmed correctly is identified by the microprocessor of the RCP.

Should an alarm or trouble condition occur, the assigned address of the device is known rather than just a

zone that contains multiple devices. NOTE: Devices connected to an addressable RCP must be approved

for use with that panel. A conventional device will not work on an addressable RCP.

Conventional release control panel: A release control panel that does not display the name of the

device that has been activated or “trouble” condition but only displays the zone that the device is

connected to. Generally, rather than a readable display, only a light (LED) on the RCP is lit. If a zone

goes into a “trouble” condition, each device and associated connections and wiring must be examined

until the device, connection, and/or problem with the wiring is discovered and repaired.

Non-volatile History Buffer: Memory of previous activities will not be lost upon loss of all electrical

power sources i.e., AC or battery. All U. L. Listed addressable RCP have a non-volatile history buffer

that records all events of the panel including alarm and trouble conditions, loss of A.C. power, loss of

battery charge, low battery condition, etc. Some conventional RCP do have a non-volatile history.

The three proprietary detector control panels (really RCP’s) are addressable RCP with non-volatile

history buffer (memory). Conventional RCP are not acceptable not only due to the downtime required to

trace the entire system to discover (and repair) the source of the trouble but only an addressable RCP can

be used to cause the agent discharge or not discharge based upon the programming of the devices. Many

RCP used within Chrysler Group LLC facilities are connected to two forms of fire suppression (gas agent

and a water spray). Only an addressable RCP can be used to discharge one agent over the other, or

discharge both with a time lag based upon how a device is programmed (based upon its assigned

address). Addressable RCPs are completely field programmable and configurable from the front panel

keyboard.

Standard 105 65

For the ME group, generally the machine manufacturer subcontracts the fire suppression system(s) to a

Chrysler Group LLC approved and licensed fire protection contractor. The fire protection contractor

used is based upon what panel manufacturer’s equipment is already at the plant. For a new plant, this is

not an issue unless the new facility will under the control of an adjacent facility that has a preference for

a particular manufacturer.

If the bid is an open bid, a few pre-qualified fire protection contractors bid the project(s) and generally

the contractor with the lowest bid gets the work.

Key manufacturers that make fire suppression systems and equipment used at Chrysler Group LLC

facilities are Detector Electronics/Detronics, Notifier, Fike, Fenwal and Siemens.

Once a fire protection contractor is contracted, the fire suppression system installed will be a system

using equipment from the distributor of the fire protection contractor. There are some devices that may

be used regardless of the distributor. But if a Fike RCP (for example) will be installed, the associated

devices used in the installation will be manufactured by Fike (or compatible with Fike).

There are dry contacts (relay) within the RCP that are connected to various interlocks related to the

machining operations. Before a gas agent is discharged, certain operations are interlocked to shutdown.

Electrical power to the protected machine/equipment is shut-off using a dry contact. Generally the

systems are designed to allow a machining sequence to be completed before the electric power is

disconnected. This interlock includes the cutting oil pump(s).

Dampers within exhaust ductwork will be interlocked to close using a dry contact. Hydraulic pumps are

interlocked to shut-off before the gas agent is discharged. Also, air handlers and/or oil mist units are

interlocked to shut-off before the agent is discharged.

SINGLE HAZARD PANELS (SHP)

SHP’s are normally not acceptable for any Chrysler Group LLC installation. Written permission must be

obtained in advance from the Chrysler Group LLC Corporate Fire Prevention Engineer. NOTE: A

contractor shall not automatically bid using a SHP unless the Chrysler Group LLC specifications

specifically state that a SHP can be used. Bidding a project using a SHP without specific written

instructions shall require the contractor to supply an addressable Release control panel at no additional

cost to Chrysler Group LLC.

Items that will be considered upon accepting a SHP for a particular project are:

1). Number of detection devices required, including detector required over Release control panel.

2). Fact that SHP have no history buffer which might be critical to have for a particular application.

3). SHP panels usually only have two detection circuits, both are usually required for providing

sequential zoning within the room or equipment. Therefore, additional cost may have to be calculated for

installing the smoke detector over the SHP to the building’s fire alarm system.

4) By-pass switches within an enclosure that can be locked with a Chrysler Group LLC provided padlock

will required. Individual switches will include, as a minimum - AC-power, DC-power, detection circuits,

any interlock circuits, and purge fan control circuit.

If a SHP is acceptable to the Chrysler Group LLC Corporate Fire Prevention Engineer, only this engineer

shall approve the manufacturer and model of the SHP to be installed.

Any SHP for a system protecting a room shall not be installed within the protected room.

Standard 105 66

17.0 Interlocks

All safety interlocks shall be direct (hard) wired to the shut-down devices and not the programmable

control panel enclosure.

Interlocks connected by software shall comply with the additional requirements:

1. The shutdowns are programmed in the PLC safety logic

The following equipment shall be interlocked to shutdown upon actuation:

Assembly (Conveyor) Line

Supply and Return Ventilation – only upon booth sprinkler operation (for new installations the

ventilation supply and return runs continuously)

Power Supply to Paint Spray Booth Painting Equipment

Electrostatic spray systems shall be interlocked to de-energize when not in use.

17.4 Computer Room

Computer and ventilation equipment shall be interlocked to shutdown, and ventilation dampers

interlocked to close upon actuation of a gas system detector, manual pull station or suppression system

pressure switch. Since two detection zones are required as part of a gas system actuation, shutdown of

equipment takes place upon detection by either the first or second zone of detection. Refer to Chrysler

Group LLC Fire Protection Standard #103, “Acceptance Test Standards”, for proper system operation

and sequence of interlocked shutdown requirements.

Once the initial acceptance test of the shutdown interlocks is witnessed by a member of the Corporate or

GRC and documented, yearly shutdown testing does not have to be conducted. However, if additional

equipment or modifications to the existing computer room are made in the previous year then shutdown

testing shall be conducted and witnessed by a member of the Corporate or GRC.

Standard 105 69

18.0 Fire Protection During Construction

18.1 General

Fires during construction operations are an imminent threat. Fire potential is inherently greater during

these operations than in the completed structure due to the presence of large quantities of combustible

materials and ignition sources. Arson is also a threat during construction operations due to excessive

combustible materials and open access at the construction site.

A construction fire safety program shall encompass the following:

- Housekeeping

- On-site Security

- Installation of Fire Suppression Systems (as Construction Progresses)

- Organization and Training of an On-Site Fire Brigade

- Communications

- Protection of Special Hazards

18.2 Hazards of Construction

Building construction requires considerable amounts of combustible building materials to perform the

task.

Fire retardant tarpaulins or materials of similar fire retardant characteristics (fire retardant treated wood)

shall be used for covering the building supplies and temporary enclosure of buildings.

Concrete should be poured as quickly as possible after combustible forms have been constructed. The

combustible forms shall be removed as soon as possible after the concrete has set properly.

Fireproofing material should be applied to structural members as soon as possible to afford fire

protection to structural members.

Trash accumulation can present a fire hazard at the construction site. Daily cleanup of debris is required

to remove the hazard and provide an orderly-working environment. Trash containers shall be provided

on site for proper storage of debris. Combustible trash shall be removed daily.

Cutting, burning, and welding operations provide an ignition source. A Hot Work permit system for

cutting, welding and burning operations, as specified by fire protection standards and the insurance

carrier, provides controls for safe “hot” work operations.

Portable heaters are an ignition source and must be U.L. listed.

Small quantities of flammable liquids can be safely handled and stored in approved safety containers.

Flammable liquids shall be stored in an isolated location. Bulk quantities of flammable or combustible

liquids shall not be allowed.

Internal combustion engines shall be placed to avoid exhaust discharge near combustibles. The engine

shall be shut down during re-fueling to prevent flash fires. Internal combustion engine driven equipment

shall not be used below grade.

The use of tar kettles shall be permitted outdoors away from combustibles or on a non-combustible floor

or roof of a building.

temperature sprinkler heads. This protection based on the type of column can be a one-(1) hour rated

coating or sidewall sprinklers at the 15 feet level.

Pile sizes shall be limited to 2,000 square feet with a minimum 8 feet aisle for manual fire fighting.

Standard 105 73

See CFS 106 for storage requirement details

19.3 Assembly “In” Plant Vehicle Gas Fill Operations

This applies to all Assembly Plants that have inside gasoline fill operations which utilize a containment

pit and fuel farm where gasoline is piped to a manual or semi-automatic robotic fill system.

Gasoline shall be piped through a preset meter and dispense less than ½ of the vehicle fuel tank capacity

(this will prevent an overfilled tank if a vehicle is fueled on the next shift).

The tank farm fuel pumping system shall not pressurize the system greater than 45-50 psi.

Provide in the pit an automatic or semi automatic water wash, gaseous agent suppression with rate of rise

heat detection and a wet pipe automatic sprinkler system with a separate control valve. Continuous low

level ventilation shall be provided. Airflow switches should be monitored. The exhaust ductwork shall

also be provided with automatic wet pipe with sprinklers installed maximum on 10 –12 ft. centers.

Interlocks shall be provided such that the ventilation system is de-energized when the gaseous agent

suppression system is activated. In addition the main dispensing pumps shall be deactivated.

Provide area signage with “No smoking or open flames” as well as stripping the “red” area zone for 20 ft.

minimum in all directions. Signs stating “Only approved cell phones, pagers and radios allowed in area”

should be posted in area.

Electrical equipment shall be classified for the area.

Pit ventilation shall be interlocked such that if not proven the gas dispensers will not operate

Provide portable first aid fire fighting equipment throughout the area.

Standard 105 74

Do not allow walkie talkies, pagers, cell phones etc. in the area unless they are approved by a recognized

testing agency for use in hazardous locations.

Provide an emergency fuel tank shutdown button in two remote locations from the gas fill operation.

Shutdown button should be interlocked to shutdown conveyor and activate water wash system.

Provide a spring loaded fusible link valve where the incoming gasoline line penetrates the main building

floor or wall and a valve near the fuel pumping equipment.

The gasoline piping from the entry point into the building and the connection point of the fuel dispensers

shall be seamless or welded seam whenever it will be over equipment or processes that emit sparks or

produces heat. These would include welders, ovens and furnaces. The welding of the piping system must

be done by or supervised by a certified welder in pressure piping welding.

All plans for the fuel fill operation or any modifications to the area must be submitted in writing to

Corporate Fire Engineer and GRC for review and comment.

19.4 Hydraulic Fluid Systems

Hydraulic Fluid Systems - New Installations:

Use an FM approved less flammable hydraulic fluid where possible.

Before purchasing new hydraulic equipment, the manufacturer of the equipment should be consulted to

determine if an FM approved less flammable hydraulic fluid could be used in their equipment. Ensure

pumps, seals, gaskets, packing and other system components are checked to ensure they are suitable for

the approved less flammable fluid to be used.

Petroleum based hydraulic fluid systems:

1). Emergency shutoff switches should be provided for shutting down hydraulic pumps in the event of a

pipe failure or fire. Switches shall be well marked and readily accessible under any anticipated fire

conditions.

2). Flexible hose used for connections should be steel reinforced, designed for the hydraulic fluid being

used and capable of withstanding four times the maximum working pressure. Hoses should not rub

against other objects as a result of machine movement, vibration, or pressure surges.

3). Avoid using threaded pipe. However, if used, weld joints using a qualified welder following

American Welding Society (AWS) or ANSI/ASME procedures. A safety factor of eight over maximum

working pressures should be used.

4). Secure/anchor all pipe and tubing to minimize failure due to vibration.

Fire Protection for Petroleum Based Hydraulic Oil Systems:

Sprinkler protection shall be provided over all hydraulic oil equipment unless written permission is

obtained from the Chrysler Group LLC Corporate Fire Prevention Engineer or GRC.

NOTE: Normally this will only occur over a single small hydraulic system associated with a detached

operation located in a non-combustible structure and located adjacent to non-combustible occupancy

(ignition sources normally not present) and the business interruption potential is low i.e., lost production

can be readily made up by other existing equipment and damaged equipment can be readily replaced. A

provision for prompt manual shutdown of the system must be provided.

Standard 105 75

Besides automatic sprinkler protection, the additional degree of protection will depend on two issues –

1). The total quantity of petroleum based hydraulic oil that can be released from hydraulic equipment,

assuming that the pumps are not shutoff and 2) the normal presence of ignition sources during operating

the equipment such as molten metal, heaters, or other hot surfaces above the auto-ignition temperature of

the oil being used, open flames or spark producing equipment, such as welding machines.

As a minimum, provide automatic sprinklers over the hydraulic equipment and at least 20 feet beyond in

all directions. Also, provide sprinkler protection for all shielded areas, such as pits beneath equipment or

platforms.

Sprinkler protection may be dictated by the surrounding occupancy. Based upon Chrysler Group LLC

Standards, minimum sprinkler design shall be 0.30-gpm per sq. ft. over the most remote 4,000 sq. ft. plus

500-gpm hose stream allowance using 286°F sprinklers.

Portable fire extinguishers (Class ABC) suitable for flammable liquids fires shall be provided. Provide a

minimum of a 15# CO2 or 20# dry chemical unit for the area

For any petroleum based hydraulic oil system(s) with individual reservoirs/tanks containing more than

100-gallons of petroleum-based hydraulic oil or aggregate 100-gallon within 20-feet of individual tanks,

an automatic actuated means for shutting down the oil pump(s) and shutting off the flow from

accumulators for hydraulic systems may be required.

If required by the Chrysler Group LLC Corporate Fire Prevention Engineer:

Automatic shutdown of the hydraulic system(s) can be best accomplished by using a thermally actuated

fire detection system (such as linear heat detection wire) located directly above the hydraulic operated

equipment and at least 20 feet beyond in all directions. Interlock the thermally actuated fire detection

system with the emergency stop switch or power supply to the oil pump. The thermal detection device

should be rated at least 50ºF above the highest anticipated operating environment temperature.

The use of using a sprinkler water flow switch as a method to automatically shutoff the hydraulic system

should be discouraged. Same is true for oil reservoir liquid level switches unless it can be proven to

activate the power interlock before 25-gallons or less of hydraulic oil are released.

Large Capacity Systems:

Very large (1,000 gallons or greater capacity) petroleum-base hydraulic oil systems should be located in

a minimum one-hour rated cutoff room protected by automatic sprinklers.

FM Approved Less Hazardous Fluids:

FM approved less hazardous fluids are either of the high water base (oil-in-water emulsion), water-in-oil

emulsion, water-glycol, or synthetic types. These are referred to Internationally as HF-A, HF-B, HF-C

and HF-D fluids respectively.

HF-A fluids contain 90% or more water. They are usually used in light-duty applications –pressure below

1,000 psi using special pumps. Recommended temperature limits are 40ºF to 120ºF.

HF-B fluids consist of 35% to 40% water in mineral oil, with a small amount of emulsifying agent, rust

inhibitors and anti-wear additives. Recommended temperature limits are 15ºF to 150ºF.

HF-C fluids consist of 35% to 50% water for fire resistance, ethylene or propylene glycol to improve low

temperature properties, and additives for proper viscosity and resistance to corrosion, wear and bacteria.

Recommended temperature limits are 0ºF to 150ºF with normal operations at 120ºF to 150ºF.

Most synthetic fluids (HF-D fluids) are one of four types: phosphate esters, chlorinated hydrocarbons,

blends of phosphate esters and chlorinated hydrocarbons, and fluids containing other compositions.

Recommended temperature limits are 20ºF to 200ºF.

Standard 105 76

Synthetic fluids are not compatible with natural rubber, Buna, or neoprene seals or hoses. Synthetic

fluids also may attack metal protective paints, lacquers and electrical wiring insulation.

19.5 Platforms

Platforms (solid and/or grated flooring):

Platforms that are 36-inches or higher, above finished floor, and wider than 48 inches shall be protected

by one of the following methods:

a) An approved skirting method around the perimeter that prevents any storage from being
