Wall mounted OS&Y valves are an acceptable installation for sprinkler systems when required pipe
length for an outside PIV is restricted. They should be avoided, if possible.
5.7 Hydrants
Hydrants provide water supply from the site underground fire water main to mobile fire equipment for
distribution.
For new construction projects, if required by AHJ, hydrants shall be provided on the underground main.
Hydrant spacing shall be a maximum of 300 feet around the perimeter of a building/site. Hydrants shall
be located a minimum of 40 feet from a building (unless physically impossible). Wall hydrants shall only
be utilized if the underground is not “looped” and protection is required on the “un-looped” side.
Private yard hydrants shall be provided only with two 2½-inch outlets or as directed by local AHJ and
approved by Corporate and GRC. Where existing on hydrants, pumper connections shall be welded shut.
Hydrants shall be provided with drainage capability and threads compatible with those used by the local

G4S Secure Solutions (G4S) Site Security Manager or on-site security representative.
5.8 Fire Department Connections (FDC)
Fire department connections shall be incorporated to private water fire protection systems as a
supplementary water supply to a city or fire pump supply (for pressure). Fire pumper connections shall
be installed on the discharge side of the fire pump(s). Additional fire department connections may be
required in conjunction with sprinkler systems if building size or special hazard warrants. Fire
department connections are not required for each sprinkler system.
5.9 Valves Pits
Backflow prevention devices adjacent to a city water supply are typically installed in valve pits. Valve
pits installed underground shall be constructed of concrete, shall be provided with drainage, and shall
have a ship’s ladder for entrance and exit of the pit for inspection and maintenance. NFPA 24 provides
specific design requirements for valve pits. Valve pits shall require confined space entry procedures for
entry; check with the S&PD safety representative.
Other devices required in a valve pit are shut-off valves, a metering device for monitoring consumed
water, and a strainer.
These devices can be installed in a fire pump house or in a pump room of a building, if approved by the
AHJ.
5.10 Backflow Prevention
Connections of site water to a city main shall have a check valve in the tie-in line to prohibit backflow of
site water into the city water supply. Local and state building codes shall be consulted for required or
allowed variations of check valve arrangements. Backflow preventors on fire pump systems shall be
located on the discharge side of the fire pump unless not allowed by the local AHJ.
Types of backflow prevention are as follows:

5.11 Hydrostatic Tests
All new piping, including underground piping and fire department connections, shall be hydrostatically
tested at not less than 200 PSI (13.8 bars) for two hours. When the maximum pressure in the system is
greater than 150 PSI (10.3 bars), the test pressure shall be 50 PSI (3.4 bars) above the maximum system
pressure. The test pressure shall be read at a gauge installed at the lowest elevation of the system or
portion of the system being tested.
No visible leakage shall be noted from the sprinkler piping. The amount of leakage for underground
piping shall not exceed two quarts 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 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.
Hydrostatic testing of sprinkler systems shall be witnessed by a member of Corporate and/or GRC or a
designated representative.
5.12 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 until the water “runs” clear. Care
shall be exercised during the flushing operation to assure that water flow will adequately drain without
producing damage to surroundings.
Flow rates, in accordance with latest edition of NFPA 13 They are as follows:
Flow Rate required to produce a velocity of 10 fps (3 m/s) in pipes
Pipe Size (in inches) Pipe Size (mm) Gallons/Minute Liters/Minute
4 102 390 1476
6 152 880 3331
8 203 1560 5905
10 254 2440 9235
12 305 3520 13323
If the water supply will not produce the required flow as shown above, the hydraulically designed
sprinkler system demand rate shall be used as a minimum. If the water supply will not produce the
desired hydraulically calculated demand rate, the maximum flow rate available for the pipe schedule
system shall be used.
Standard 106 22
All flushing operations of fire protection main and lead-in shall be witnessed by a member of Corporate
and GRC.
Standard 106 23
6.0 Water Supply
6.1 Suction Supply
Water supply to a fire pump shall be from a reliable supply source with adequate volume and pressure to
meet the required demand. Water supply sources are city water supply, elevated storage tanks, ground
level storage tanks, or underground storage tanks as approved by Corporate and GRC.
A connection to a city water supply shall be provided in accordance with NFPA 24. The connection,
thrust blocks, backflow prevention device, metering, shut-off valves and backfill shall be considered
when connecting to a city water supply. A manual tank level float shall be installed on all ground level
suction tanks. A temperature-indicating device shall also be installed and shall be located in the pump
house.
The suction tank shall be sized based upon the greatest sprinkler system design demand and hose stream
allowance. The water supply duration shall be for a minimum of two (2) hours.
6.2 Fire Pump House
Fire pump houses shall be of non-combustible construction. Pre-engineered (metal) pump houses are not
acceptable.
Fire pump houses shall be 100% protected by sprinklers when a diesel driven fire pump is present. The
sprinkler riser shall be located in the fire pump house. Sprinkler system water supply shall be from the
discharge side of the fire pump. The fire pump house shall be heated (40F) to prevent fire pumps and
piping from freezing.
If diesel engine-driven fire pump(s) are used, louvers operated by the fire pump controller are required to
provide combustion air to the fire pump(s). The louvers shall be located to ensure that any water mains
within the fire pump house are not exposed to cold weather drafts or sub-freezing temperatures.
Fire pump houses shall be locked. Keys and access shall be provided in accordance with a plant’s
emergency operating procedure. Locking of a fire pump house does not eliminate the need to lock the
control valves located in the fire pump house.
Drainage shall be provided to the exterior or floor drains to prevent flooding of the fire pump house
during the weekly “churn” test. All fire pumps shall sit on an elevated pad.
If diesel engine-driven fire pumps are used, containment shall be provided for the entire quantity of the
diesel fuel in the event of a diesel fuel leak or spill (either from diking or a tank within a tank). The fuel
tank size shall be sufficient to operate the given fire pump for a minimum of eight hours. This is
normally one gallon of fuel per horsepower plus 10%. The fuel tank shall be located inside of the fire
pump house. Each diesel driven fire pump shall have its own individual fuel tank.
A laminated piping schematic of the underground with valves, fire pumps, etc., shall be provided in the
fire pump house.
A telephone shall be provided in the pump house for emergency use.
Standard 106 24
6.3 Fire Pumps
Fire pumps shall be provided where required to meet volume and pressure demands for a building/site
fire protection water supply system, including sprinkler and hose demands. The largest sprinkler demand
with hose streams allowed shall be less than 120% of the gpm rating of the fire pump. If the largest
demand exceeds 120% of the gpm rating, the Corporate Fire Prevention Engineer shall be contacted
before the fire pump is ordered and installed.
Fire pumps shall be listed by Underwriters Laboratories (U.L.) and Factory Mutual (FM). NOTE: ULC
in Canada.
Fire pumps shall have a rated capacity sufficient to meet the largest fire protection system demand.
Fire pump location, size, driver type, and installation shall be in accordance with designer, NFPA, and
GRC, Corporate requirements.
If the fire pump serves one building, such as an office complex, the largest system demand would be the
most remote sprinkler system for the complex or the top-most sprinkler system for a multi-story building.
All fire pump couplings shall be a Falk T-10 or other FM approved metallic coupling only, no plastic
couplings. Alternatives such as all metal drive-shaft (U-joint) between the pump and driver are
acceptable as long as they are approved by GRC.
If the fire pump serves many buildings, such as a manufacturing (assembly) plant, the largest, remote
system demand would be a special hazard area, such as a paint spray booth water spray system,
flammable liquid storage room foam-water system, or a tire storage deluge system. The most demanding
of these systems would constitute the remote system demand for the plant/complex. (see attached chart
on fire pump piping requirements)
NOTE: All fire pumps and Jockey pumps will have individual pressure sensing lines.
Standard 106 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.) for fire protection services. FM does
not approve jockey pumps.
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.
Standard 106 26
Chrysler Security Services staff shall be contacted before a jockey pump is replaced to ensure it is of
adequate capacity and pressure rating. . In no case should a jockey pump be sized such that it can
provide more than 175-psi on underground system. A pressure relief valve shall be required on the
discharge side of jockey pump system.
6.5 Fire Pump Types and Quantities
Fire pumps shall be either electric or diesel driven.
The number of water sources is determined by the dollar amount at risk at the site. Corporate insurance
along with the S&PD management shall determine this amount, then in discussion with the Loss
Prevention Consultant, the number of supplies can be determined.
Standard 106 27
70 Roof Decks
7.1 General – New Construction
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.
Factory Mutual 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 Factory Mutual 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.
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)
An insulated steel deck roof is designated Class I 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 Class II.
7.2.2 Roof Covering Classifications (NFPA)
Three classes of fire resistive roof coverings in accordance with NFPA are as follows:
Class A 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.
Chrysler Group LLC will only accept Class “A” roof covering installations!
Standard 106 28
7.3 Construction of Roofs
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.
Steel decks roofs shall have slight slopes to permit water run-off and to prevent puddles from forming.
All steel decks and their above deck components must be approved for use in a single installation. The
Corporate Office shall be contacted with all roof design criteria to determine their Class I compatibility.
7.4 Standing Seam Roof Systems
This system is used in pre-engineered building structures. The roof system must meet all FM criteria.
Standard 106 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 two 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,
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 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.
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 No. 251, “Fire tests for
Building Construction and Materials”.
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.
A minimum two (2) hour rated fire barrier wall shall be provided between the office and warehouse. The
AHJ may require a fire rating greater than two (2) hours. In multi-story buildings, vertical fire spread
Standard 106 30
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 fuel and heat sources,
flammable-liquid storage tanks from main-plant buildings, and storage from office 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.
Fire ratings and requirements are set by the local AHJ and local Building Code and Chrysler Group LLC.
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 106 31
9.0 Fire Alarm Systems
9.1 System Types
• For new or replaced fire alarm or evacuation systems see documents “A and B” under Standard 106 in
the FBOK
Fire protection signaling systems are classified according to the function they are expected to perform.
Types of systems are as follows:
9.1.1 Local Systems
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.
9.1.2 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 installed 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.
9.1.3 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.
9.1.4 Proprietary Systems
Proprietary and central station systems are similar in operation. The main difference is as follows:
- 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.
Standard 106 32
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.
Chrysler Group LLC’s PDC normally send signals from the proprietary panel to a certified central
station. The central station then calls the fire department and others on a predetermined basis. The
central station and alarm system type (manufacturer) shall be determined by Mopar Facilities and the
Mopar Security Manager.
9.2 Alarm Point Monitoring Requirements
Points to alarm include the following:
- Water flow switches (vane type and pressure switch)
- Control valves shall be locked in the wide-open position.
- Detectors (smoke, heat, flame)
- Manual pull stations
- Fire pump including selector power switch position, diesel engine trouble condition, pump
house power, etc. These are usually series trouble points in that a response to the fire pump
room is required to determine the exact problem
- Fire pump operating, firewater suction tank level, firewater suction tank temperature, diesel fuel tank
level (provide a low fuel switch to alarm at the 5/8 level of the diesel fuel tank), temperature of fire
pump house.
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 alarmed to a central station and locally where personnel are normally present.
- Supervisory Signal - In sprinklered 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 alarmed to a
central station and locally 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.
Standard 106 33
- Public areas of 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/strobe unit.
The fire alarm system shall comply with requirements of 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.
Standard 106 34

response type. NOTE: An all purpose type foam is available.
EXAMPLE TO SIZE A FOAM TANK USING 3% AFFF
1. Assumption- rack storage 5 tiers high
2. Assumption- Room size is greater than 3000 square feet. If room size is less than 3000 use that
figure x .4 gpm/ sq. ft.
3. Ceiling demand = .4 gpm/sq. ft. for 3000 sq. ft. = 1200 gpm
4. Rack demand = 4 levels x 6 hds./level x 30 gpm/hd.= 720 gpm 5 tiers of storage requires 4 levels of
in-racks
5. Balance demand = 120 gpm
6. Total demand =3 + 4 + 5 = 2040 gpm
7. Total duration = 20 minutes
8. Total foam demand = 6 x 7 x 3% = 2040 x 20 x .03 = 1224 gallons of foam
9. The required foam tank size is based upon the actual calculated foam demand by the installing
contractor.
Additional sprinkler protection shall be provided under all elevated tote storage racks.

Standard 106 37
12.0 Inside Fire Hose & Fire Extinguishers
12.1 General
NFPA No. 13, 2007 edition does not require 1.5-inch fire hose drops or hose stations if approved by
local AHJ. If fire hose drops are required by local AHJ, fire hose control valves (1.5”) must have built-in
pressure limiting device that limits pressure to 80-psi. Pressure limiting disks shall not be used as a
method to reduce pressure.

14.0 Automatic Sprinkler System
14.1 Classification of Occupancy
The function (use) of a building, as directed by the building code and the Authority Having Jurisdiction,
is the determining criterion 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 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.
- 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 Extra Hazard occupancies with little or no flammable or combustible liquids.
- Group II involves Extra Hazard occupancies 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.
Standard 106 41
14.2 Design Densities
Minimum sprinkler system design densities shall be as follows for PDC warehousing and support areas:
NOTE: Use 100 PSI as maximum design pressure at the base of the riser.

per square foot for the most remote 4,000 square feet. Sprinkler head type (up-right or pendent) should
be determined in conjunction with the room design parameters.
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 latest edition of Factory Mutual Data Sheet 2-2 and NFPA
13.
Guidelines for ESFR sprinkler applications shall be found in the latest version of NFPA No. 13 and
Factory Mutual Data Sheet 2-2. 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
- Corporate and GRC shall be consulted before specifying the use of ESFR sprinklers
Note: If a Depot is protected by ESFR sprinklers at the ceiling and a mezzanine area is provided,
sprinkler protection beneath the mezzanine must use FM Global approved quick-response sprinklers with
Standard 106 42
water shields. The sprinkler design criteria for any mezzanine shall include a minimum of two ESFR
heads as part of the hydraulic calculations.
Side-wall 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.

Computer rooms shall have a fire resistance rating of at least one hour and shall be located adjacent to
non-hazardous processes or operations. Openings in floors or walls shall be sealed to maintain the
intended rating of the barrier.
Interior finish shall be non-combustible.
Raised floors are common with computer rooms to channel equipment cables and to provide ventilation
to the computer room. Raised floors shall be non-combustible. Carpeting is permitted if it has a flame
spread rating of 25 or less.
Mechanical ventilation equipment shutdown is required as part of suppression system actuation.
15.1.2 Fire Protection
Fire suppression for computer rooms shall consist of sprinklers and clean agent.
If only under-floor protection is provided for a computer room, carbon dioxide is acceptable.
A purge fan is not required by Corporate, but may be requested in consultation with the end user.
When a purge fan is used for the removal of gas and unburned particles of combustion, the fan must be
interlocked so that if the fan is running the gas agent cannot be discharged. Control of the switch
controlling the purge system shall be within the gas agent locked release control panel and switch shall be
monitored or other suitable method used to ensure fan cannot operate during a gas agent discharge.
Sprinkler design density shall be 0.15 GPM per square foot for the most remote 2,500 square feet.
Equipment shutdown, dampers, door closers, and sealing of all penetrations and openings are required
for effective suppression system operation.
Standard 106 46
If the room is used as a terminal room only, with no mainframe, then sprinkler protection only is
adequate. Smoke detectors by themselves with no sprinklers are not considered adequate fire protection.
Tape carousels, if provided, shall be protected with a total flood suppression system.
A smoke detector is not required over the release control panel as Chrysler Group LLC 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.
15.2 Offices
15.2.1 Construction
All office areas shall use non-combustible interior partitions, floors, ceilings, and wall coverings (flame
spread rating of 25 or less).
The entire office shall be cut-off from the warehouse area by a minimuim of a two (2) hour rated wall or
greater if specified by the AHJ and the local Building Code.
15.2.2 Fire Protection
All office areas shall be provided with wet pipe sprinklers. The design density shall not be less than .15
gpm per square feet for the most remote 2,500 square feet. Protection is also required above any
suspended ceiling if combustible construction or materials are present.

Carousels are motorized and retrieval systems that revolve around a fixed base.
They have two long parallel sides connected by short round ends. Most carousels revolve in a horizontal
plane and are 8 to 10 feet high with 1 or 2 picking levels. The width of the bin spaces and containers is
generally uniform in size.
15.3.2 Fire Protection
- The area shall be designated “No Smoking.”
- The area shall be draft curtained (5 feet deep) from the remainder of the warehouse if ESFR
sprinklers are used to protect the warehouse.
- Approved smoke detector shall be installed at the ceiling level to shut down the carousel
movement. Where the operator can “see” the entire carousel and uses a “dead-person” type
control to transverse the carousel, detector are not required.
- Provide 1½-inch fire hoses to reach all areas of the carousel.
- Sprinkler protection at the ceiling designed for a density of .30 GPM per square foot over the
most remote 4,000 square feet.
- Two levels of in-rack sprinklers are required (generally). One level just above the first level
mezzanine and the other level at approximately one-half the distance from the floor to the
underside of the mezzanine.
- In-rack sprinklers shall be fed separately from the ceiling sprinklers and can be located between
carousel units.
- Sprinklers are needed interior to each carousel unit if the units do not have solid backs to
prevent flame spread.
- If sprinkler clearance above the top of the carousel exceeds 20 feet, then a solid non-
combustible barrier 3 to 10 feet above the carousels with sprinkler located below the barrier.
Standard 106 47
- For prompt operation of the in-rack sprinklers, a continuous solid shield directly above the in-
rack sprinklers “running” the full length of the carousel shall be provided. This “heat
collecting” strip may be supported from the sprinkler piping.
- An eight-foot clear aisle shall be provided around the carousel unit.
15.4 Automatic Storage & Retrieval Systems - ASRS
Each ASRS system is unique; thus fire protection and construction guidelines shall be established after
consultation with GRC and Chrysler Security Services staff. In general, in-rack sprinkler protection as
well as “face” sprinklers are required as well as solid barriers.
Standard 106 48
16.0 Rack Shelving
16.1 Solid and Slatted
Solid and slatted shelves shall not be utilized in rack storage. For purposes of this Standard, slatted
shelves are considered the same as solid shelves.
Solid shelves, in existing PDC locations, shall be removed and replaced with open wire grates that
provide adequate sprinkler water penetration.
16.2 Wire Mesh
All new shelving for all racks shall be open wire mesh to allow sprinkler water penetration into the racks.
The use of open metal mesh does not negate the need for in-rack sprinklers where required due to the
rack heights or multiple rows.
Standard 106 49
17.0 Racking Categories and Fire Protection
17.1 Commodity Classification
The following are the insurance carrier guidelines for commodity classification. These classifications are
used to determine the correct sprinkler design. Generally PDC warehousing is considered “Plastic
Commodity” when designing a new warehouse.
- Class I: Essentially non-combustible commodities in light cardboard or paper packaging
materials. There should be no plastics in the product or packaging materials unless the inclusion
of the plastic does not change the overall combustibility of the commodity from the basic
definition. For example, a light plastic film wrapping around metal cans to replace a light paper
wrapping would be a significant change in the overall combustibility.
- Class II: Essentially non-combustible commodities in heavy corrugated cardboard or wood
packaging. There should be no plastics in the product or packaging material unless the
inclusion of the plastic does not change the overall combustibility of the commodity from the
basic definition. For example, small polystyrene foam corner blocks in the wood crating of a
piece of machinery would not require a change in the Class II classification.
- Class III: Commodities produced from ordinary combustibles such as wood, paper and natural
fibers in cartons with a limited amount of plastic in the product or in the packaging material.
However, the combined amounts of any such plastic in the product, packing, and container shall
not exceed 10% of either the volume or the weight of an individual commodity.
- High density, solid plastics shall not exceed 10% of the weight of the product or packaging
material (not including pallet).
- Cellular plastics shall not exceed 10% of the volume of the product or packaging material (not
including pallets).
NOTE: This does not mean that there could be 10% plastics in the entire warehouse, but that the
combination of packaging and product in individual loads could have up to 10% plastic.
- Class IV: This commodity classification encompasses the following products that have an
above-average rate-of-heat release. Plastic, Class I, II, or III commodities that contain more
than a negligible amount of plastics in the actual product or in the packaging material.
However, the combined amounts of any such plastics in the products, packing, and container
shall not exceed 25% or either the volume or the weight of an individual commodity, or a
configuration that presents an abnormal amount of exposed surfaces.
- High density, solid plastics shall not exceed 25% of the weight of the product or packaging
material (not including pallet).
- Cellular plastics shall not exceed 25% of the volume of the product or packaging material (not
including pallet). NOTE: This does not mean there could be 25% plastics in the entire
warehouse, but that the combined packaging and product in individual loads could have up to
25% plastic.
- There are two manufacturers of fire retardant treated, expanded plastic packaging material that
have been listed by FM as a Class IV commodity. The packaging material, an expanded
polyurethane, is injected into the carton to form around the product. If the product itself is a
Class I through III commodity, the carton containing the product and this packaging system
would be considered a Class IV commodity. The listed packaging systems are:
- Carpenter Packaging Company’s “Richguard IV Polyurethane Expanded Plastic
Material.”
- Sealed Air Corporation’s “Guardpak Polyurethane Expanded Plastic Packaging
Material.”
NFPA Standard No. 13 is then consulted after the commodity classification and storage
arrangements are determined to design the sprinkler systems, in-rack (if required), etc.
Standard 106 50
17.2 Rack Types
This Standard refers to the following rack classification. Any deviations from these classes shall be
referred to Chrysler Security Services staff and the PDC Security Management.
- Single Row
- Double Row
- Multiple Row
- Portable
- Bin
- Palletized
17.3 Fire Protection Requirements
The following information is required to determine the most economic and practical fire protection for
any rack storage situation:
- Building height and clearance above the top of storage to sprinkler deflectors.
- Maximum Anticipated Storage Height.
- Commodity description and classification.
- Type of storage handling, i.e.; clamp truck, automatic stacker, etc.
- Type of packaging (cartoned, uncartoned, encapsulated, etc.).
- Aisle width.
- Shelves.
- Number of storage tiers.
- Available water supplies.
- Sprinkler system type (wet or dry).
Once the information is obtained, proper design can be obtained. General guidelines are not part of the
scope of this Standard. The above information is required and then after discussion with Corporate and
GRC a protection scheme is designed.
Single and double row rack storage to 15 feet with plastic commodities and mesh shelves do not require
in-rack sprinklers when stored under an ESFR or 0.60-gpm design sprinkler system.
Single and double row rack storage to 20 feet with plastic commodities and mesh shelves do not require
in-rack sprinkler when stored under an ESFR.
Single, double and multiple row rack storage up to 25 feet with plastic commodities and mesh shelves
does not require in-rack sprinklers when stored under an ESFR sprinkler system.
Portable, bin and palletized storage up to 15 feet can be stored under a 0.60-gpm design or ESFR
Portable, bin and palletized storage up to 20 feet can be stored under an ESFR sprinkler system.
All expanded plastic (urethane) will require in-rack sprinklers at every tier of rack storage.

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.
The ability to provide a 4th
tone must be provided as a shelter in place 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.
Exposed wiring for horns and 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, Chrysler
Security Services. The local authority having jurisdiction (AHJ) involvement shall be determined on a
plant by plant basis by Plant Management. A sound meter shall be utilized for all speaker testing.
19.3 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 to be introduced
below the platform.
b) Automatic sprinkler protection designed to provide a minimum density of 0.30-gpm per square
feet over the most remote 4,000 square feet (or entire platform area) plus 500-gpm hose stream
allowance for platforms up to six-feet in height. Platforms six-feet and over in height shall have
sprinkler protection designed to provide a minimum density of 0.60-gpm per square feet over
the most remote 4,000 square feet (or entire platform area) plus 500-gpm hose stream allowance
or as stated by the Corporate Fire Prevention Engineer.
Standard 106 53
An approved skirting method shall be composed of one of the following:
a) Sheet metal panels attached around the perimeter by fasteners such as bolts, screws, clips, etc.
Panels shall be able to be removed for a visual inspection and cleaning of any debris that may
collect in the area below the platform.
b) Horizontal metal bars (such as Unistrut) or framework attached to the platform’s vertical
supports and spaced a maximum of 12-inches between horizontal metal bars. Metal bars shall be
attached by a method where access is available for cleaning any debris under the platform.
A process above the platform that involves flammable or combustible liquids requires automatic
sprinkler protection to be installed regardless of platform height.
Platforms less than 36-inches in height, not utilizing flammable or combustible liquids, shall be arranged
for visual management and cleaning but will not require skirting or automatic sprinkler protection unless
required by the local Authority Having Jurisdiction (AHJ).
19.4 Air Conditioning Replacement Fluid (HFO-1234yf)
HFO-1234yf characteristics:
1. Gaseous
2. Clear
3. Slight Odor
4. Flammable Gas Under Pressure
5. Ignition Temperature 761 degrees F (405 degrees C)
6. Explosive Limits 6.2 % - 12.3 %
7. Vapor heavier than air (vapor density 4)
8. NFPA Hazard Classification – Health 2, Flammability 4
All canisters of HFO-1234yf shall be stored inside a flammable liquid room or an approved flammable
liquid cabinet.
19.5 Rubber Tire Storage
Rubber tires are stored in Canadian Depots in an interlaced (see drawings) fashion using portable racks
(palletiers) to a height of 20 feet. Tires are generally not stored in US Depots.
This section is a general summary of NFPA No. 13 on rubber tire storage. The definition section of CFS
106 has information on rubber tire storage.
The arrangement of storage is vital to the sprinkler design density. Drawings of the various storage
arrangements and racks are included at the end of section 19.3.
NFPA 13 and any applicable IRI Interpretive guides must be utilized for the protection of rubber tire
storage in Chrysler Group LLC National and Field Depots.
Storage Using Standard Spray Sprinklers
Pyramid piles on side up to 5 feet- .19gpm/2000 sq. ft.
Tires on tread on floor 5-12 feet- .3gpm/2500 sq. ft.
Portable racks on side storage up to 5 feet. - .19 gpm/2000 sq. ft.
5-20 feet- see NFPA
20-25 feet- .6 gpm/5000 sq. ft.
Standard 106 54
Storage Using ESFR Sprinkler Protection
On side, on tread, portable racks- up to 25 feet storage in a 30 feet building – design 12 heads at 50 psi
up to 25 feet in a 35 feet building- design 12 heads at 75 psi
Laced tires in portable racks up to 25 feet in a 30 feet building- design 20 heads at 75 psi
In buildings used for tire storage the required sprinkler protection shall extend 15 feet beyond the
perimeter of the tire storage area.
Refer all tire storage over 25 feet to this office for review and development of applicable protection
recommendations
Inside small fire hose stations must be provided for final extinguishment of rubber tires.
Column steel protection is required when on floor or on side storage in portable racks are over 15 feet.
This requirement can be waived if ceiling protection can provide both a .90 gpm/sq ft. density over the
most remote 3000 sq. ft. and a .6 gpm per sq. feet density over the most remote 5000 sq. ft. using high
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 2000 square feet with a minimum 8 feet aisle for manual fire fighting.
