IntroductionNovec™ 1230 is a clean, safe fire fighting agent for use in total flooding automatic extinguishing systems It is intended as a long term replacement for Halon 1301 and, whilst maintaining the excellent fire suppression properties of Halon, has none of the environmental problems Storage and distribution requirements are similar to Halon and the majority of system components are identical However, Novec™ 1230 is not a direct replacement for existing Halon 1301 installations due to the difference in agent quantity and discharge characteristics The minimum Novec™ 1230 design concentration for Class A hazards is 42% for UL Listed systems For Class B hazards it is at least 585%

The US Environmental Protection Agency (EPA) accepts use in normally occupied areas where the concentration doesn't exceed 10% The safe use criteria has further been confirmed by the Halon Alternative Group (HAG) report Refer to NFPA 2001, 2008 edition “Clean Agent Fire Extinguishing Systems,” Section 1-5 “Safety,” for additional exposure requirements

The systems described in this manual are ‘engineered’ Engineered systems for example, may consist of several SAPPHIRE containers, modularised or manifolded together and connected via a pipe network to a number of discharge nozzles

Systems may be activated mechanically or electrically Mechanical manual actuation is via a manual actuator attached to the container valve Electrical actuation is via a removable side mounted solenoid or a top mounted electrical actuator Actuation can occur automatically via a signal from a detection and alarm control panel

Users of this manual should find that sufficient information is provided to plan, design, purchase components, install, operate and maintain the system However, in the event that part of the document is not understood, or if there is any concern as to the suitability of the protection, do not hesitate to contact one of our specialist engineers for the matter to be quickly resolved

Approvals and StandardsThe SAPPHIRE manufactured equipment and the Novec™ 1230 agent, manufactured by 3M™, have comprehensive approvals and listings providing further support to the overall product

Novec™ 1230 AgentApprovals include, but are not limited to:• Underwriters Laboratories Inc (UL) Recognised

Component

• NFPA 2001 Clean Agent Fire Extinguishing Systems (Listed Alternative)

• US EPA SNAP Rpt (Unrestricted Listed Alternative)

• Australian Industrial Chemicals Notification (Approved)

• German Institute for Environmental Hygiene and Medicine (Approved)

Manufactured Systems• Underwriters Laboratories Inc

SAPPHIRE systems are manufactured in strict accordance with the internationally recognised Quality assurance Standard, BS EN IS0 9000 and approved to ISO 9001SAPPHIRE Extinguishing System units are to be designed, installed, inspected, maintained, tested and recharged by qualified, trained personnel in accordance with The Standard on Clean Agent Fire Extinguishing Systems, NFPA2001, 2008 edition and to be used in accordance with Environmental Protection Agency (EPA) Significant New Alternatives Program (SNAP) Where determined to be appropriate by the authority having jurisdiction, other applicable standards may additionally be utilised to specific system requirements for these purposes

Health and SafetyA properly designed and installed extinguishing system should not present any significant health or safety problems, however, there are basic precautions to be taken to avoid accidents, and aspects of the system operation that should be understood End-users often require reassurance regarding the safety of personnel, and this can only be given if a thorough understanding of the properties of the agent and its effects in different situations are known Best practice should be observed

Novec™ 1230 extinguishes primarily through heat absorption, and does not sufficiently deplete oxygen levels

Therefore, exposure to Novec™ 1230 at the design concentration of 42%, and up to 100%, is not hazardous to health Exposure to higher concentrations is permissible for limited periods Refer to NFPA 2001, 2008 edition Section 1-5 “Safety,” for exposure requirements As with halons, the US EPA and the National Fire Protection Association (NFPA) recommend that unnecessary exposure to any agent be avoided and that personnel evacuate protected areas as quickly as possible to avoid the decomposition products of the fire

Novec™ 1230 will decompose at high temperatures to form halogen acids If so, their presence is readily detected as a sharp, pungent odour long before hazardous maximum exposure levels are reached Fire toxicity studies conclude that generally decomposition products from the fire itself, especially carbon monoxide, smoke, heat, and oxygen depletion, create a greater hazard

The noise created by the Novec™ 1230 agent discharging can be loud enough to startle people in the vicinity, but is unlikely to cause any permanent injury Turbulence caused by the high velocity discharge can dislodge substantial objects directly in its path, and cause enough general turbulence within the protected area to move paper and light objects

Direct contact with the vaporising liquid discharged from an Novec™ 1230 nozzle may have a chilling effect on objects and in extreme cases may cause frostbite to the skin The liquid phase vaporises rapidly when mixed with air and therefore limits the risk to the immediate vicinity of the nozzle Minor reduction in visibility may occur for a brief period due to the condensation of water vapour

! WARNING

The discharge of clean agent systems to extinguish a fire can result in a potential hazard to personnel from the natural form of the clean agent or from the products of combustion that results from exposure of the agent to the fire or hot surfaces Unnecessary exposure of personnel either to the natural agent or to the products of decomposition shall be avoided


First Aid

Refer to the Novec™ 1230 Material Safety Data Sheet within Appendix C

Novec™ 1230 Agent CharacteristicsNovec™ 1230 is a clean agent containing no particles or oily residues It is produced under ISO 9002 guidelines to strict manufacturing specifications ensuring product purity Novec™ 1230 leaves no residue or oily deposits on delicate electronic equipment, and can be removed from the protected space by ventilation

Novec™ 1230 is thermally and chemically stable, but without the extremely long atmospheric lifetimes associated with some other clean agents The atmospheric lifetime of Novec™ 1230 has been determined to be 5 days (Reference 3M™) The US EPA SNAP does not consider Novec™ 1230 to be a long lived substance when discharged, and as such has placed no restrictions on its use (Environmental Protection Agency’s Significant New Alternatives Program)

Typical areas that may be protected by a SAPPHIRE system are detailed below; the list is by no means exhaustive:

Bank VaultsLibrariesRare Book StoresElectronic Data ProcessingTelephone ExchangesStudiosCommunication CentresTransformer and SwitchroomsControl RoomsTest LaboratoriesFlammable Liquid Stores

The present understanding of the functioning of Novec™ 1230 is that its fire fighting effectiveness is achieved through heat absorption Complete suppression using Novec™ 1230 has the following advantages:

• Less visual obscurity and minimal risk to personnel

• Low toxicity

• Most effective when used with automatic detection to introduce Novec™ 1230 with a 10 second discharge

• The ability to prevent re-ignition providing concentration levels are maintained

Novec™ 1230 is stored as a liquid in approved IS 7285 (Part2): 2004 containers and is super-pressurised with dry nitrogen to 25 bar @ 21 °C (360 psi @ 70 °F)

! WARNING

Novec™ 1230 shall not be used on fires involving the following materials unless they have been tested to the satisfaction of the authority having jurisdiction:

• Certain chemicals or mixtures of chemicals, such as cellulose nitrate and gunpowder, that are capable of rapid oxidation in the absence of air

• Reactive metals such as lithium, sodium, potassium, magnesium, titanium, zirconium, uranium and plutonium

• Metal hydrides

• Chemicals capable of undergoing autothermal decomposition, such as certain organic peroxidase and hydrazine

Principle of OperationThe SAPPHIRE valve is a high-flow-rate device specially designed for use in fire systems Operation is by means of a pressure-differential piston Container pressure is used within the valve to create a positive force on the piston, sealing the valve closed Operation of the valve occurs when the upper chamber is vented faster than the ‘make up device’ in the shuttle can replace the pressure Thereby allowing, the shuttle to be forced up, and free flow of Novec™ 1230 from the valve Upper chamber pressure is released by the electrical, mechanical or pneumatic actuator

The valve incorporates the following features:• A pressure operated safety release device (burst disc)

• Main outlet, fitted with anti-recoil cap

• A connection for a pneumatic, mechanical or electrical actuator, fitted with safety cap

• A connection for an electrical solenoid

• A connection for the pneumatic actuation port

ManifoldsManifolds are fabricated sections of steel pipework They enable multiple containers to be connected to a common pipe network They may also be used in systems where main / reserve containers arrangements are required

Manifolding requirements are:• Use Schedule 40 black iron, galvanized, chrome-

plated, or stainless steel pipe conforming to ASTM A53, or A106 All fittings must be a minimum Class 300, malleable or ductile iron

• After welding, make certain all inlet holes in the pipe are clean of any weld spatter and are completely open

• Pipe unions are acceptable

• Reducing bushings and reducing fittings are allowed when reducing pipe size

• Cast iron pipe and fittings are not acceptable

• PTFE (Teflon) tape is the only acceptable pipe sealant and must be applied to male threads only Do not allow tape to overlap the pipe opening, as this could cause possible blockage of the agent Thread sealant or compound must not be used

• Before assembling the pipe and fittings, make certain all ends are carefully reamed and blown clear of chips, debris and scale The inside of pipe and fittings must be free of oil and dirt

Figure 28 - Typical Manifold System

System DesignThere are two main elements of system design The first is the risk assessment; determining the type of protection required, considerations such as ventilation, openings and restrictions; equipment location etc The second is calculating the quantity of Novec™ 1230 required, including floor and/or ceiling voids, positioning of nozzles, electrical requirements, etc

All systems are designed in accordance with NFPA 2001

Hazard AnalysisThe first, and one of the most important, exercises in planning a SAPPHIRE extinguishing system is the hazard survey The information derived from the survey should include risk assessment, environmental conditions, personnel considerations, system operation both in normal conditions and after a discharge, access and construction limitations, dimensions, volumes, and any special requirements

SAPPHIRE systems are suitable for use in normal commercial and industrial environments The minimum design concentration for Class A & C fires is 42% but differs for Class B fires To determine other recommended design concentrations for Class B flammable liquids, refer to the technical support centre All design concentration calculations are based on extinguishing concentrations plus 20% safety factor for Class A & C and 30% safety factor for Class B

All agent quantities are calculated at minimum design temperature to determine agent quantity Maximum achieved concentration should be calculated at the maximum anticipated enclosure temperature, and compared to NOAEL / LOAEL values, see Table 3

The Novec™ 1230 cupburner value* is 45% for commercial grade Heptane, and an extinguishing concentration of 35% for Class A materials

Calculations to determine minimum design concentration:

Cupburner or fire test concentration x safety factor

Safety factor: Class A = 12Class B = 13Class C = Class A

For Class A (Determined by fire test) -35 x 12 = 42%

For Class B (Commercial grade Heptane)-45% x 13 = 585%

For Class B (Other class B fuels)-cupburner x 13 = design concentration

For Class C -Use at least design concentration for Class A surfaces fires (42%)

For systems with only manual actuation -cupburner x 13 = design concentration but not less than 585%

Rugged environments, and those requiring intrinsically safe or flameproof equipment, require special consideration and should be discussed fully with the technical support centre before finalising a system design Novec™ 1230 is suitable for use with the following materials:

Class A Fires involving solid materials usually of an organic nature, in which combustion normally takes place with the formation of glowing embers

Class B Fires involving flammable liquids or liquefiable solids and flammable gases

Class C Fires involving energized electrical equipment where the electrical nonconductivity of the extinguishing media is of importance

* Cupburner and Cupburner value as defined in NFPA 2001

29


SAPPHIRE (UL)570805002011-03

Note: Certain materials in this group may require increased concentrations to achieve satisfactory extinguishment Consult the technical support centre for details of specific risk

Hazard VolumeIn total flooding applications the risk area must comprise an enclosed space with no significant openings so that the design concentration can be achieved and maintained Generally, the calculation is based on an empty area; the subsequent furniture and fittings having little effect on the actual concentration Similarly, large equipment cabinets and control panels should not be considered in the calculation as it is assumed that the internal area is required to be filled with agent

Each enclosed space is considered as a risk area and requires at least one nozzle A floor void, ceiling void, cable duct, etc, is treated as a separate adjacent area and requires simultaneous discharge to occur

Ceiling obstructions such as beams that are less than 300 mm (12 in) below the slab need not be considered Obstructions greater than 300 mm (12 in) can affect the distribution of agent and may require additional nozzles Consult the technical support centre if in doubt

To determine the volume refer to the site drawings, ensuring that the scale is accurate and that heights are denoted, or make a sketch of the area adding dimensions and any relevant details Calculate the volume of each area

Hazard StructureThe protected enclosure shall be bounded by rigid elements of building construction The ceiling should be not less than 03 m (1 ft) above the hazard

During agent discharge, the hazard enclosure will experience a pressure change Consideration should be given to mitigating these pressure changes

30


! CAUTION

Novec™ 1230 is not effective on the following: -

• Class A Deep seated fires

• Class D Combustible metals

• Chemicals capable of auto-thermal recomposition

• Chemicals capable of rapid oxidation

• Enclosures with hot surfaces (>400 °C) (752 °F)


VentilationIf the hazard enclosure has no means of adequate venting after discharge, consideration should be given to installing a normally closed means of ventilation with extraction arrangements which will discharge directly to atmosphere

Air conditioning and/or forced ventilation can affect the system performance and the quantity of agent required

(i) Self-contained air conditioning unit

A self-contained unit conditions the air within the enclosure and does not rely on a fresh air supply, or draw air from other parts of the building

If the hazard has a self-contained unit and it is located within the area without an outside air supply, no additional agent is required It is not necessary to shut down the unit prior to a discharge as the mixing effect is beneficial

(ii) Central air conditioning unit

A central air conditioning unit relies on air from outside and is often linked by ducts to other parts of the building, therefore, prior to a discharge, the unit should be shut down and/or dampers operated to close the ducts Sufficient time must be allowed for the plant to stop, or dampers to close, before discharge occurs

Dampers should be installed in both supply and return air ducts, as close as possible to the area The duct volume between the hazard and the damper must be added to the overall volume

Hazard TemperatureDetermine as accurately as possible the anticipated minimum and maximum temperatures likely to be experienced within the protected area Minimum agent quantity requirements are based on minimum temperature At maximum temperature, hazard concentration must not exceed the NOAEL/LOAEL values for normally occupied spaces, reference NFPA 2001, “Safety” section

Agent QuantitiesNormally the agent quantity is the weight required to produce the desired concentration at the lowest temperature within the hazard enclosure

Agent StorageNovec™ 1230 is stored as a liquid in appropriate containers to meet IS 7285 (Part 2): 2004 requirements Nitrogen in the container maintains a superpressurisation of 25 bar at 21 °C (360 psi at 70 °F) The chosen location should provide protection from severe weather, mechanical, chemical, or other types of damage

Once assembled, filled and pressurised the SAPPHIRE extinguishing system should not be exposed to temperatures outside the storage/operating temperature range of 0 to 55 °C (32 °F to 130 °F) This also includes while being in storage or transported

Hydraulic calculations assume an agent temperature of 21 °C (70 °F) When the storage temperature varies by 55 °C (10 °F), there is a risk that the system will not supply the designed quantity of extinguishing agent

Hazard FuelsAll fuels in the hazard must be identified and the corresponding agent concentration requirements assessed The design concentration (percent by volume) required for the hazard will be the highest concentration required by any one of the fuels present in the hazard

Personnel Safety

Symptoms of overexposure to concentrations greater than 100% may include dizziness, impaired coordination, reduced mental acuity, cardiac effects or unconsciousnessIn the event of overexposure, remove to fresh air immediately and summon medical assistance

31


! WARNING

Direct skin contact with Novec™ 1230 in the immediate area of discharge may cause frostbite

! CAUTION

To avoid possible injury, avoid any exposure to Novec™ 1230 in volume concentrations greater than 10% unless using self contained breathing apparatus Limit exposure times as in NFPA 2001, “Safety” section

SAPPHIRE (UL)570805002011-03

ManifoldsIt may be necessary to manifold agent containers to provide the required amount of agent for a hazard, or to make available the proper increments of agent weight for the protection of multiple hazards

Whenever containers are manifolded, the following rules must be observed

1 All containers connected to the same manifold or pipe must be the same size and filled with the same agent weight, pressure and fill density

2 Agent containers must be located in a single row and spaced according to section

3 A connected reserve may be employed in some circumstances providing a secondary supply of agent

4 Flexible discharge hoses and check valves must be used at each inlet

Agent DistributionDistribution piping will be installed only with approved piping as indicated in Section 5

Pipe size reductions may be made by using reducing tees or reducing bushings or reducing couplings

32



Agent Flow Characteristics

Nitrogen SuperpressurisationNitrogen is added to the SAPPHIRE containers This addition of nitrogen, known as superpressurisation, will cause a portion of the nitrogen to mix with the Novec™ 1230, the remaining portion of the nitrogen will remain in the vapour space above the liquid providing the increased propulsion necessary to discharge the Novec™ 1230 from the container

Flow in PipeIn a properly designed distribution piping network the flow of Novec™ 1230 will consist of a two phase mixture of liquid and vapour The properties of this mixture will vary with its composition; therefore, when the mixture contacts the pipeline walls, the friction decreases the density of the mixture resulting in a non-linear pressure drop and an increase in flow velocity

Another consequence of two-phase flow is the potential for separation of liquid and vapour In a properly designed pipe network, the velocity of the mixture will be high enough to maintain highly turbulent flow However, if the pipeline diameter is too large for the design flow rate, the two phases may separate, leading to alternate discharges of liquid and vapour (slugging) or layering of the two phases Therefore, the pipeline must be properly sized to keep the Novec™ 1230 flow turbulent enough to prevent phase separation

Initial Vapour DischargeAt the instant the discharge valve is opened, rapid expansion of the agent will cool the piping network

Trailing Vapour PressureDischarge time is defined as the average liquid discharge time through all nozzles in the system After the liquid portion of the discharge has been completed, there will be a short transition period followed by the delivery of the remaining Novec™ 1230 nitrogen mixture as a vapour This is due to flashing of the trailing edge of the fluid as it moves from the tank to the nozzles In some systems the transition period is relatively long; this can lead to confusion as to when the discharge is complete, possibly resulting in an inaccurate measurement of the discharge time

Nozzle Selection and LocationThe number of nozzles required is based on the hazard size and configuration and the coverage provided by the nozzle Nozzles are available in 7-port or 16-port versions to provide 180 or 360 degree discharge patterns respectively When considering the optimum nozzle location, the following factors should be taken into account

• Nozzle location is affected by the shape of the hazard area

• The maximum discharge radius is 91 m (30 ft) for a 360° nozzle and 150 m (4925 ft) for a 180° nozzle

• The maximum coverage area for either nozzle is 1672 m² (1800 ft²)

• Nozzle orifices must not be placed where they may discharge into nearby objects

• Nozzles must be installed a maximum of 300 mm (12 in) below the ceiling

• 43 m (14 ft) maximum protection height for a single row of 360° and 180° nozzle For ceiling heights over 43 m additional rows of nozzles may be added

• 180° nozzles must be mounted adjacent to a wall and must be located to cover the entire area

• 300 mm (12 in) minimum void height (ie Sub-floors and false ceilings)

• Sub-floor nozzles may be positioned either vertically down from the top of the sub-floor or vertically up from the bottom of the sub-floor

• Maximum distance 180° nozzles should be placed from a wall 300 mm (12 in), the minimum 50 mm (2 in) Measured from centre of the nozzle to the wall

• Nozzles located both above and below the container outlet, Maximum distance between them 91 m (30 ft)

• Nozzles located either above or below the container outlet, maximum distance between them 91 m (30 ft)

Design Example - CalculationsMinimum Agent Quantity is based on the hazard volume at the minimum anticipated temperature and concentration required To determine the minimum agent quantity the following equation is used:

W = (V/S) (C/100-C)

W = Weight of agent required (kg)

V = Hazard volume (m³)

S = Specific Vapour Volume (m³/kg)

S = 00664 + 0000274t

t = Design Temperature in Hazard Area (°C)

C = Required Novec™ 1230 Design Concentration (% by

volume) at Design Temperature (t)

Example:Calculation for two rooms and floor void with the following dimensions:

Switch Room: 70 x 69 x 25 = 1208 m³

Computer Room: 160 x 120 x 28 = 5376 m³

Floor Void: 160 x 120 x 034 = 653 m³

t = 21 °C for calculation example

Switch Room: (520% required design concentration example only)

W = 1208 x 52 = 918 kg0072154 (100-52)

Computer Room: (52% required design concentration example only)

W = 5376 x 52 = 4087 kg0072154 (100-52)

Floor Void: (52% required design concentration example only)

W = 653 x 52 = 496 kg0072154 (100-52)

When the minimum quantity of Novec™ 1230 has been calculated the weight is compared to the available agent container size The container size must be equal to or greater then the weight of agent (see Table 4)

With the appropriate container selected, the previous equation can be rearranged to determine the concentration based on the actual weight as containers are filled to the nearest kilogram

C = 100 WS WS + V

To calculate the required agent for each hazard volume as a percentage of the total agent required;

% Hazard Agent = Individual hazard volumeSum of hazard volumes

Switch Room: 1208/7237 = 167% of agent

Computer Room: 5376/7237 = 743% of agent

Floor Void: 653/7237 = 90% of agent

It is determined from the above that both the Switch Room and the Computer Room can be fed by one manifolded system using 5 x 120 litre containers, each filled with 101 kg of agent The Floor Void would use 1 x 80 litre container filled with 50 kg as it requires less than 10% of the total agent and therefore equates as follows (Separate tank is required for floor voids If protected with nozzle from computer room system, the piping would be outside the tee split limits)

Switch Room: 1208/6584 = 183% of agent

Computer Room: 5376/6584 = 817% of agent

Floor Void: 653/653 = 100% of agent

Actual agent to Switch Room :

0183 x 5 x 101 = 924 kg

Agent to Computer Room :

(5 x 101) - 924 = 4126 kg

After determining the minimum weight and concentra-tion, the maximumconcentration can be determined byrecalculating the equation based on the maximum tem-perature anticipated in each enclosure 270C (800F) maxi-mum design temperature This calculation is required todetermine if the maximum concentration is below theNOAEL limit for normally occupied areas

Switch Room: C = 100 x 1502 x 22538 = 736% (1502 x 2253) + 42626

Computer Room: C = 100 x 6778 x 22538 = 736% (6778 x 2253) + 192371

Floor Void: C = 100 x 80 x 22538 = 734% (80 x 2253) + 22754

The minimum enclosure concentrations can be calcu-lated based on the actual container fill (70oF minimumdesign temperature)

Switch Room: C = 100 x 1502 x2207 = 722% (1502x2207)+42626

Computer Room: C = 100 x 6778 x 2207 = 722% (6778 x 2207)+192371

Floor Void: C = 100 x 80 x 2207 = 72% (80 x 2207) + 22754

Figure 28 - Example Nozzle Location

Switch Room: 42626/234997 = 1814% of Agent

Computer Room: 192371/234997 = 819% of Agent

Floor Void: 22754/22754 = 100% of Agent

Actual agent to switch Room :

01814 x 3 x 276 = 1502 lbs

Agent to Computer room :

Piping PracticesDue to the two phase flow of Novec™ 1230, certain piping practices must be adhered to, mainly that the flow split must be on the horizontal plane There are two types of tee used in SAPPHIRE systems, a through/side tee and a bull tee Both have limitations on the minimum and maximum allowable flow splits which are detailed on page 36

It should also be noted that system designers shall allow a minimum of 10 times the nominal pipe diameter around tee splits before any change of direction

System designers should aim to design as far as possible balanced pipe networks, use minimum lengths of pipe, use minimum numbers of elbows, maximize pipe volume before the first tee and incorporate similar pipe run lengths to nozzles

IntroductionIn determining the quantity of Novec™ 1230 required for a particular application, it is important to assess the hazard area correctly The following information will need to be determined as discussed in Section 3

1 Hazard Volume

2 Minimum Room Temperature

3 Hazard Type

4 Height above sea-level

The Hazard volume can be determined by calculating the room volume and deducting any impermeable volumes that may be contained within the area The anticipated temperature of the Hazard area will normally be advised by the client The agent concentration is dependant upon the type of hazard being protected and hazard altitude The quantity of Novec™ 1230 can be calculated by using the flooding factors (Table 8: Metric / Table 9: Imperial) or by using the formula (Novec™ 1230 Equation Calculations) and then multiplying by the altitude correction factor (Table 10)

Example:

Hazard Volume: 280 m³Room Temperature: 20 °CAgent Concentration: 42%Flooding Factor: 060992

Quantity of Novec™ 1230 required: 0.60992 x 280 = 170.8 kg

Note: Specific Vapour Volume data shown in Tables 8 and 9 are experimentally derived values and the specific vapour volume equation (S) has a correlation coefficient of 099 However the equation can be used to give a close approximation of required agent quantities

Table 9: Novec™ 1230 Weight Calculations Imperial

Table 10: Altitude Correction FactorAt elevations above sea-level, Novec™ 1230 has a greater specific volume because of the reduced atmospheric pressure A system designed for sea-level conditions will therefore develop an actual higher concentration at levels above sea-level and an actual lower concentration at levels below sea-level The adjusted agent quantity is calculated by multiplying W (from the equation on the left) by the altitude correction factor The design quantity of the clean agent shall be adjusted to compensate for ambient pressure that vary more than 11 percent (equivalent to approximately 915 m (3000 ft) of elevation change) from standard sea level pressure 760 mm Hg at 0 °C (2992 in Hg at 70 °F)

Engineered SystemsEngineered systems are based on a Hydraulic Flow Program developed by Hughes Associates Inc The program predicts the two phase flow of Novec™ 1230 and nitrogen through a pipe network Information detailing the enclosure is entered and the program calculates the required pipe sizes, nozzle drill sizes, average nozzle pressures and discharge time For further information on the Flow Program, refer to the Hughes Flow Program User’s Manual

As system design calculations are critical to the success of the extinguishing system, only trained personnel are permitted to perform system calculations If in the future, other companies wish to use the program, representatives will be required to attend a formal training session All system calculations are conducted ‘in house’ or by authorised suppliers

Note: The calculation method has been designed for specific types of fittings, pipes, and pipe inside diameter When these limitations are not maintained, there is a risk that the system will not supply the required quantity of extinguishing agent

Program ParametersWhen designing pipe network systems, the following design parameters should be considered to avoid system reject when running the calculation

• 50 bar (73 psi) minimum nozzle pressure

• 80% maximum agent in pipe

• Between 6 - 10 seconds discharge time

• 10 - 35 % side tee split

• 30 -70 % bull tee split

• 05 kg/l (312 lb/ft³) - 12 kg/l (749 lb/ft³) fill density

• Max liquid arrival time imbalance of 10 seconds

• Maximum liquid run out time of 20 seconds

• Maximum nozzle height is 43 m (140 ft)

• Minimum of 10% agent in pipe before first tee

• Maximum of 20 nozzles per system

• Maximum of 10 enclosures per system

• The ratio between the nozzle area and the pipe cross sectional area immediately preceding the nozzle is limited to a minimum of 020 (20%) and a maximum of 080 (80%)

(For extended discharge consult the technical support centre)

• Combining the correct containers to obtain the required quantity of agent within a specific hazard area

A typical 80 mm (3 in), three port manifold assembly consists of the manifold, three check valves and an end cap Each check valve is screwed to the manifold

1 Fix the back channels of the mounting brackets to the wall at the appropriate heights (see Table 14), using suitable anchor type bolts (not supplied)

2 Position the containers against the back channels with the valve outlets pointing left at the required spacing for the manifold ports

3 Insert the container straps at top and bottom and secure with the bolts provided (see Figure 42)

Manifold Bracket Installation1 Fix the two back vertical channels to the wall at the

appropriate height using suitable anchor type bolts (see Table 15)

Back channels are used to ensure that the appropriate height adjustment is available when connecting the discharge hose from the valve outlet to the manifold check valve (see Figure 43)

2 Locate and secure the cantilever brackets to each channel using M10 x 40 mm Hex Head screw and uninut long spring 10 mm

3 Locate manifold brackets in cantilever channel and unirax end caps

4 Remove anti-recoil cap and attach discharge hose between valve and manifold Adjust cantilever height as required and secure in position

5 For safety remove discharge hose and replace safety caps, while pipework is installed

Figure 62 - Low Pressure Switch Wiring (Parallel).

Discharge Pressure Switch (Continued)There are two ways this switch can be wired; for feedback to a control panel or, for direct equipment shutdown

For pressure switch feedback to a panel, the toggle on the switch should read “OFF” and the switch should be oriented such that the toggle is pointing downward, facing the plunger, with an EOL resistor wired across the terminals as shown This orientation allows for the contacts of the switch to be open at atmospheric pressure so the panel will see the EOL device When the system is actuated, the plunger will cause the switch to close, creating short circuit and indicating a discharge at the panel

For direct equipment shutdown, the toggle position is reversed from above: the toggle is moved to the “ON” position (such that the contacts are closed during normal operation) with the orientation remaining the same (toggle pointed down towards the plunger) Both contacts can then be used to wire to equipment, one side to a rated power source (120 VAC, 250 VDC, etc) and the other to the equipment being controlled This will allow for the circuit to open up upon system actuation, interrupting current flow to the equipment being controlled

Low Pressure SwitchAll container valves are ‘Factory fitted’ with low pressure warning switches Voltage input can be applied to either terminalThe low pressure switch can be connected two different ways, in parallel or in series with the end of line (EOL) device The prefered method is in parallel with the EOL device as this will allow the panel to differentiate between an open-circuit fault in the wiring and an actual low container pressure supervisory conditionConnecting the low pressure switch in series with the EOL device may result in some authorities having jurisdiction (AHJs) not accepting this particular wiring scheme

Completion ProceduresFor ease of reference completion procedures may be subdivided into the following sections;

• Pre Checks and Visual Inspections

• Final Connections

• Hand over Procedures

Pre-checks and Visual Inspections

General

When the installation is complete, and before making the final connections, the following checks should be made:

Mechanical Checks

Inspect protected area closely for conformance to original risk specifications and for enclosable openings or sources of agent loss which may have been overlooked in the original specification

• Building work should be thoroughly checked to ensure that enclosures have been properly constructed and that voids in floors and above suspended ceilings have been sealed

• All back channels should be secured firmly to the wall or bulk head

• Containers should be securely held within brackets

• Piping should be securely fixed within hangers

• All pipe connections must be tight

• Nozzles to be the proper type, correctly placed, and properly orientated

• Check model and weight markings on container nameplates to verify that correct containers and charges have been installed as required

• Verify that all warning and instruction plates are mounted where required

Electrical Checks

The electrical systems may include interfaces with many other systems for alarm, indication, actuation, shutdown, etc For complex electrical systems the scope and operating requirements will be described in other documents Electrical checks are given below for a basic system using electrical actuation of the container valve;

• Remove top mounted electrical actuator from valve Check that electrical actuator is activated when system is triggered

During detection system actuation verify the following functions operate;

• All apertures in hazard enclosure are closed by dampers or other suitable methods

• Provide 292 bar (4235 psi) pressure to the master container valve pilot hose

• Verify all pneumatic actuator pistons are in the fired position

60


! CAUTION

The completion of the installation system, commissioning tests and hand-over may occur before the area is ready for use In the event of delay between hand-over and the risk area being available for protection, then the system must be left in a ‘safe’ condition to avoid accidental discharge The system must only be made operative once the area for protection has been completed and is operational


Hand-over ProceduresThe entire system shall be thoroughly inspected to make sure that it is complete and that all tests required during installation have been properly carried out In addition, the following items are particularly important1 A container should be refilled or replaced when it

shows a loss in agent quantity of more than 5% or a loss in pressure (adjusted for temperature) of more than 10% (Operating pressure of unit at 25 bar at 21 °C, 360 psi at 70 °F) Refer to Appendix A for pressures at other container temperatures

2 Check container weight information label against system requirement If there is any doubt or if there has been a loss of weight, then the container must be weighed

3 Make sure the system is armed and the actuating systems are operational

Ensure adequate escape routes with directional signs are provided Issue of the appropriate documentation shall constitute completion of the Hand-over procedure

Appropriate records shall be issued by fire and/or insurance authorities as to the suitability, acceptability and availability of the system for the hazard area

• Check for leaks There must be less than 10% loss in pressure within 1 minute)

Before replacing the pneumatic actuators, ensure that all pistons are fully reset (see Figure 52) After reinstalling the pneumatic actuators, reconnect the pilot hose to the master container valve adaptor (see Figure 54)

Final Connections

Discharge Piping

The final connection of the discharge piping occurs at the container valve assembly For single container systems, the valve anti-recoil cap can be removed and the discharge pipe connected to the container outlet For multi-container systems, the valve anti-recoil caps can be removed and all discharge hoses fitted

IntroductionThe hazard integrity is the ability to retain the discharged Novec™ 1230 For a total flooding extinguishing system to be effective, the design concentration must be achieved and then maintained for at least ten minutes The only method of testing the agent retention within the protected area is to verify the integrity of the enclosure by applying proven test procedures

The enclosure integrity test has been developed to locate the source of leaks and, from the data collected, predict the retention time, proving system performance and removing the need for actual Novec™ 1230 discharge In order to determine with any degree of confidence that the hazard area will hold the gas for the required time period, where necessary an Enclosure Integrity Test in accordance with NFPA 2001 appendix C or the authority having jurisdiction must be conducted

PrincipleThe test is conducted with a device known as a door fan, which has been used in the energy conservation field for over 25 years It has three basic components as follows:

• An adjustable panel that fits in the doorway of the protected area

• A calibrated fixed speed fan

• A variable speed fan

The pressure created by the door fan causes the air to move through leaks in the enclosure at high speed making it easy to pinpoint where leaks exist A cool chemical smoke or other air current indicator is used to detect the approximate size and location of leaks

Equivalent Leakage Area (ELA)The test to measure the ELA is conducted by blowing air into or out of the enclosure to develop the same pressure differential as would be created by the discharging Novec™ 1230 By measuring the air flow required it becomes possible to calculate the ELA, which is the total of all cracks, gaps and holes in the enclosure The leakage measurement achieved by taking air out of the enclosure (depressurisation), and then blowing air into the enclosure (pressurisation), is then averaged

Below Ceiling Leakage Area (BCLA)Experience has shown that leakage above a suspended ceiling has a negligible effect on the Novec™ 1230 concentration Like water leaking from the holes in the bottom of a swimming pool, Novec™ 1230 tends to escape from leaks in the lower part of the enclosure due to the weight of the mixture above it The rate at which Novec™ 1230 is lost is therefore primarily governed by the leakage below the floor, and walls beneath the ceiling This is called the Below Ceiling Leakage Area

Predicting Retention TimeOnce the ELA, BCLA and static pressures have been measured the next step is to calculate the retention time of the enclosure The formula is derived from a standard engineering/fluid dynamics principle The result of the calculation is the number of minutes it takes for the Novec™ 1230/air interface to reach the minimum protected height required, normally about 75% of the enclosure area

Slab to Slab WallsThe only major limitation is that it cannot be used to accurately predict a retention time if the perimeter walls do not extend from slab to slab The enclosure will almost invariably fail due to extensive leakage through the ceiling tiles

Coordination and PlanningIt should only be necessary to conduct one integrity test, therefore it is essential to ensure that the enclosure is ready, and that the relevant people have been informed Having established that any outstanding works are completed prior to the test date, advise all interested parties in writing, if necessary outlining the testing method and principles involved

62



Integrity Test Procedure

Evaluation. The enclosure and immediate surrounding area is initially examined visually to assess the readiness for testing, the existence of any attached spaces that could affect the results, and that there is an adequate relief area and return air path The volume of the enclosure is confirmed and the highest equipment measured to ascertain the required level for retention time

Preparation. All doors outside the area that are required to be open for the test are wedged open with suitable notices posted to advise personnel Where voids are protected by Novec™ 1230, tiles are removed to ensure a uniform air flow

The enclosure is put in the state it would be in prior to a discharge, eg ventilation system shut down, dampers closed, etc

Note: Equipment within the enclosure that does not affect the integrity may be left running even if it will be shut down in the event of a discharge, preventing unnecessary disruption and inconvenience

Ventilation. Air conditioning and/or forced ventilation can affect the system performance and the quantity of agent required

(i) Self-contained air conditioning unit

A self-contained unit conditions the air within the enclosure and does not rely on a fresh air supply, or draw air from other parts of the building If the hazard has a self-contained unit and it is located within the area without an outside air supply, no additional agent is required It is not necessary to shut down the unit prior to a discharge as the mixing effect is beneficial However if the air-conditioning unit is left running, a depleting concentration rather than a descending Novec™ 1230/air interface will be formed The concentration will be depleted due to leakage Therefore overgassing the enclosure may help to obtain the required ten minute retention time at minimum concentration

(ii) Central air conditioning unit

A central air conditioning unit relies on air from outside and is often linked by ducts to other parts of the building, therefore, prior to a discharge, the unit should be shut down and/or dampers operated to close the ducts Sufficient time must be allowed for the plant to stop, or dampers to close, before discharge occurs

Dampers should be installed in both supply and return air ducts, as close as possible to the area The duct volume between the hazard and the damper must be added to the overall volume

Door Fan Installation. A door fan unit is installed in the designated test door in accordance with the manufacturer’s instructions

The gauges are zeroed by taking them to full scale deflection and holding for approximately ten seconds, after which the gauges are gently tapped and zeroed

Enclosure Evaluation

Static Pressure Measurements. With the door fan equipment fully installed and set up, but with all openings closed, a measurement of any pressure difference between the enclosure and the relief area is made If the measurement is unduly high its causes are ascertained and if possible permanently reduced or eliminated

Total Enclosure Leakage Method. Using an adequate range on one fan, or a number of fans, a pressure difference of between column pressure and column pressure plus 30% is created The pressure difference, and the air flow required to generate this, is then recorded This is carried out for both pressurisation and depressurisation modes The total equivalent leakage area and the predicted retention time is calculated

Suspended Ceiling Leakage Neutralisation Method. This procedure is used to improve the accuracy of the predicted retention time where a reasonable air-tight ceiling exists, whether or not the ceiling is protected with Novec™ 1230

Note. Leak paths through the ceiling may be temporarily sealed

The volumes above and below the false ceiling are depres-surised to the same extent but using separate fans This is confirmed by using cool chemical smoke to check that no air is flowing through the false ceiling

Readings of the pressure difference between the enclo-sure, relief area, and the air flow through the fan(s) used to depressurise the room and false ceiling are made, and then the procedure is repeated in the pressurisation mode The below ceiling leakage area is then calculated and used in conjunction with the ELA to predict a revised retention time

Leakage LocationIf the enclosure fails the test, or if the client requests, an inspection of the enclosure with the door fan running can be made This makes it possible to locate the source of any leakage by using cool chemical smoke This procedure also tests the efficiency of any dampers, etc

General CommentsPersonnel required to work in the protected area should be conversant with the detection and extinguishing equipment installed, and trained in fire procedures All life-saving equipment must be properly maintained

The method of system operation is chosen at the design stage to suit the protection required for the hazard area and the environmental factors appropriate to that area This part of the document provides information relevant to ALL the standard operational systems to cover the eventuality of changes to, or expansion of the original design

System Detection and Actuation

GeneralEach system is designed to suit the hazard area, whether the area is normally manned or unmanned, and whether the detection/actuation devices are to be manual or automatic The permutation of systems is large but from an operational point of view, the systems are best grouped as:-

• Manual

• Fully Automatic

• Automatic with Manual Intervention

Manual SystemManual systems depend on human detection of a fire in the hazard area and prompt action to actuate the manual actuator for the Novec™ 1230 system to discharge and flood the protected area and extinguish the fire

All other instructions associated with manual operation form part of the user’s procedures on safety precautions and fire drill If required assistance can be provided to help the user prepare procedures for safety and fire precautions

Fully Automatic SystemWhere a sensitive fire detection system is included for the automatic release of extinguishing agent, the system shall only be capable of automatic release once two or more sensors detect the fire

The number of detectors and their spacing is designed to ensure a satisfactory response time To ensure personnel may safely evacuate the risk area an adjustable time delay should be fitted such that sufficient time may elapse prior to system discharge Ideally, the delay period shall not exceed 30 seconds

Prior to system discharge (and at the commencement of any time delay period) a clearly audible alarm different from any other used shall sound and continue until the complete system is reset In areas of high ambient noise level, a visual indication may also be required, in addition to the audible warning

The design of a system for automatic detection, signal distribution, alarms, etc is not always of our supply Therefore, details appertaining to fire detection and alarm operation and maintenance are not included in this document

UL Listed Detection & Control Equipment

Detectors shall be UL Listed for the intended application Control Panels shall be UL Listed for releasing device service and compatible with detection and SAPPHIRE Engineered Total Flooding Fire Extinguishing System

65


SAPPHIRE (UL)570805002011-03

Fully Automatic System with Manual Inter-ventionManual intervention of an automatic system may be included for the following condition;• Where personnel are required to work within the

protected area.

In protected areas where personnel are present and the concentration is greater than NOAEL, it is recommended that the automatic feature of the system is isolated during occupation This may be achieved either by an electrically contacted lock assembly or by a clearly marked key switch at a suitable location outside the risk area

Conditions During a FireThe user’s fire and safety instructions to personnel should include advice on the conditions prevailing during the discharge of a SAPPHIRE system This advice is intended to prepare the personnel for the situations likely to arise and therefore minimise the risks of panic Three major conditions prevail during Novec™ 1230 discharge of which personnel should be made aware:

Novec™ 1230 ConcentrationSAPPHIRE total flooding systems greater than 10% design concentration should only be used with manual actuation in normally occupied areas A normally occupied area is defined as an area intended for occupancy

Any area protected by Novec™ 1230 should be evacuated prior to start of system discharge Where egress of normally occupied areas cannot be accomplished within one minute, SAPPHIRE total flooding systems shall be designed not to exceed 10% concentration

Refer to NFPA 2001 for additional information

Novec™ 1230 DecompositionNovec™ 1230 decomposes when exposed to temperatures exceeding 482 °C (900 °F); such as flames, hot metal surfaces, etc The rate of this decomposition is dependent upon the size of the area where extreme temperatures are found, and also upon the length of Novec™ 1230 exposure time

To reduce decomposition, SAPPHIRE systems are designed to discharge and extinguish the fire quickly The maximum duration of discharge for these systems at 21 °C (70 °F) is 10 seconds, so the minimum amount of decomposition occurs Hydrogen Fluoride is the most toxic decomposition product This material generates a sharp acrid odour, which is easily detected and acts as a warning and a good safeguard to personnel

Novec™ 1230 Discharge ConditionsNovec™ 1230 has a low boiling point Consequently the discharge is very cold at the point where it leaves the nozzle Care should be taken to avoid working within 1 m (328 ft) of Novec™ 1230 discharge nozzles

The velocity of discharge of Novec™ 1230 from a discharge nozzle is very high Care should be taken to ensure that objects which may become dangerous projectiles are secured or removed from the hazard area

66



Actions Following a Fire

GeneralThese notes are only applicable to the hazard area(s) protected by a SAPPHIRE fire extinguishing system Where such a system may form part of, or combine with other forms of fire protection systems, then composite instructions for all systems are necessary to ensure the safety of personnel and property following a fire Assistance is available to help a client prepare composite instructions If the organisation has appointed, or nominated, a responsible person to act as a ‘Fire Officer’, actions following a fire should be co-ordinated and/or directed by the Fire Officer

Actions Immediately Following a FireThese actions should, at a minimum, include the following:

• Advise the emergency services, Fire, Accident, Police if appropriate

• Organize a ‘roll-call’ of employees and any visitors

• Prevent unauthorised personnel from entering the hazard area

• In the case of deep-seated fires, the hazard space should be kept tightly closed for at least 60 minutes after discharge of the Novec™ 1230 extinguishing agent

It is essential that the fire be completely extinguished before ventilating the space Before permitting any one to enter the space, ventilate thoroughly or ensure self-contained breathing equipment is used

• Do not enter the hazard area in which fire has been extinguished with an open flame or lighted cigarette as the possible presence of flammable vapours may cause re-ignition or explosion

Should it be necessary to enter a space containing Novec™ 1230 or decomposition products, the following precautions should be taken:

• Use a fresh air mask or self contained breathing equipment

• Do Not use a filter mask or canister type mask

• Do Not enter space unless you are under observation from outside the space, or tethered by a lifeline

• Ensure that all pressurised equipment is isolated or safe from release

IntroductionThis section provides user inspection and maintenance guidance for SAPPHIRE Engineered Systems A log book will be provided to record all inspections, maintenance, measurements and actions taken The continued capability for effective performance of an SAPPHIRE Total Flooding Fire Suppression System depends on fully adequate maintenance procedures, with periodic testing Reference NFPA 2001 and ISO 14520-1

User’s Programme of InspectionThe installer should provide the user with an inspection programme for the system and components The programme shall include instructions on the action to be taken in respect of faults The user’s inspection programme is intended to detect faults at an early stage to allow rectification before the system may have to operate

A suitable programme is as follows:-

Weekly Check of Hazard Area

Inspect the hazard area against the original layout to ensure that there have been no changes that might affect the proper performance of the fire protection system Changes might include:

• Contents of area

• Use of area

• Air Handling equipment in area

• Openings in area

• Floor/ceiling voids

• Partitioning

Weekly Check of Containers

Check storage container pressure gauges and ambient temperature Compare these pressures to the Temperature Correction Chart to determine temperature corrected pressure If the container corrected pressure shows a loss of more than 10%, the containers should be removed for weighing All measurements and actions shall be recorded in the log book

Weekly Check of System Components

Make a visual inspection of the system components, distribution piping and nozzles Check the immediate vicinity of all equipment to ensure that no accidental damage or tampering has occurred

Weekly General Check

Inspect the hazard area, access routes, container storage area, floor voids and areas above suspended ceilings to ensure housekeeping is good and that no refuse has accumulated Ensure that access to the system container assemblies and local remote controls is unobstructed

Monthly Check of Notices

Inspect system and protected spaces to ensure that warning signs, safety precautions and operating instructions are posted and clearly visible

Monthly Personnel Training Check

Check that all personnel who may have to operate the equipment or system are properly trained and are authorized to do so, and in particular that new employees have been instructed in its use

68



Contract Service and MaintenanceSystems shall be thoroughly inspected and tested for proper operation by qualified contract personnel in accordance with NFPA as well as any other standard accepted to the authority having jurisdiction Before any checks are carried out, ensure the extinguishing system is isolated electrically and mechanically and remove all electrical and pneumatic actuators No maintenance work should be carried out without obtaining approval from the Fire Officer and advising any personnel within the hazard area The following Programme should be carried out in addition to the User’s Programme of Inspection The user shall be provided with a signed and dated report of the inspection advising any rectification carried out or needed

3 Month Actuator Check

Test and service all actuating mechanisms

3 Month Electrical Systems Check

Test and service all electrical detection and alarm systems as recommended in NFPA as well as any other standard accepted to the authority having jurisdiction

6 Month Container Check

Externally inspect containers for signs of damage or unauthorised modifications Check container labels are securely fixed and legible Check container brackets and fittings

6 Month Contents Check

Examine the container pressure gauge reading and refer to the temperature correction chart If the container pressure corrected to temperature is below 10% of the stated pressure, it must be replaced or recharged

Verification of the content of Novec™ 1230 in the containers may be achieved through container weighing If containers show a extinguishant loss of more than 5% or a pressure loss (adjusted for temperature) of more than 10%, the container should be refilled or replaced

Container Weighing

Where a client does not wish to use an approved distributors maintenance contract, then containers must be weighed to establish the Novec™ 1230 content The weighing procedure is as follows:

• Remove all manual controls, pressure actuators and pressure actuation pipe or tubing and flexible electrical connectors

• Disconnect and remove discharge piping / discharge hoses from container valves

• Fit anti-recoil caps onto container valves

• Remove containers from bracketing and weigh containers Any container showing more than the maximum allowable weight loss must be recharged by a qualified recharge agent

• Record weight of container on record tag

• Replace containers in bracketing and remove anti-recoil caps

• Reconnect discharge piping / discharge hoses and all control heads, pressure actuators, pressure actuation pipe or tubing and flexible electric connectors

69


SAPPHIRE (UL)570805002011-03

6 Month Control Valve & Actuator Check

Check all manual and pneumatic actuators for free movement of the piston Replace whole unit where appropriate Check all control valves for correct manual function and automatic valves additionally, for correct automatic function

6 Month Pipe Network Check

Externally check pipework to determine its conditions Replace or pressure test and repair as necessary pipework showing corrosion or mechanical damage

6 Month Nozzle Check

Inspect nozzles for dust and debris, clean out where necessary

6 Month Enclosure Check

Carry out a full visual check of the enclosure for integrity and confirm the dimensions and the configuration of the hazard are as the original drawings or previous visit If drawings are not available and this is the first visit, then dimensions should be taken and passed to the engineering department together with the quantity of agent to enable a calculation to be carried out to ensure the correct quantity of gas has been used

12 Month Hose Check

All system hoses should be examined for damage If visual examination shows any deficiency, the hose shallbe replaced

12 Month Integrity Test

Integrity test the enclosure to determine if the leakage area has changed sufficiently from that measured during installation

Electrical Actuator Ten Year Lifespan

The removable electrical actuator has a life span of 10 years from manufacture, which is indicated on the label, and so should be replaced before this date is reached

Personnel Training

All persons who may be expected to inspect, test, maintain or operate the fire extinguishing system shall be kept adequately trained in the functions they are expected to perform Personnel working in an enclosure protected by a gaseous extinguishant shall receive training in the operation, use of the system and safety issues

70

FillingFilling can only be undertaken by trained and authorised UL fill stations using containers assembled and tested by the O.E.M. Verify that the Novec™ 1230 agent is a UL recognised virgin material.

1 With the container ready for filling, check the filling instruction sheet and the container fill weight, time, date and fill details record

2 Place the container on a scale and attach the appropriate filling adapter attached to the container valve discharge port

3 Attach the fill hose/vent line from the filling rig outlet to the filling adapter

4 Reset the scale to zero to compensate for weight of container and fill hose

5 Switch on the pump marked ‘Liquid’ on filling cabinet and fill container to required weight Refer to Fill Tolerances Table 20 (Less approximately 07 kg (15 lb) which is present in pipework and will be forced through the piping during pressurisation) When the required fill is reached, switch off pump

6 Remove container from scales, zero scales and weigh to verify fill is within tolerance Adjust if required

7 Attach low pressure switch wires to test box and regulate nitrogen pressure to 138 bar (200 psi) on fill rig and switch on supply

8 Slowly increase the nitrogen pressure on the approved pressure regulator to the stated pressure on the filling instruction sheet, making the relevant allowances in pressure to compensate for the current room temperature (see the Temperature Correction Chart, Table 21) Read off the calibrated external fill pressure gauge to determine when the intended charging pressure has been reached (Check that the container pressure gauge reads within ± 1 bar (± 145 psi) of the fill gauge Replace container gauge if outside this tolerance)

Ensure that the test box registers a change in state (normally open to normally closed or normally closed to normally open) at approximately 24 bar (350 psi) rising

9 Agitate the container using the agreed mechanical agitation equipment until the nitrogen has been fully absorbed (saturated) into the agent

10 Attach the closing down adaptor to the container valve top cap and connect the nitrogen closing down line Regulate the nitrogen pressure to 40 bar (580 psi) with the fill rig

11 Open the closing down valve for 1 second only to force the valve shuttle down The container valve will be heard to close Turn off the nitrogen supply and vent the closing down line with the needle valve

12 Vent the fill hose to atmosphere If the pressure drops to zero as shown on fill rig gauge marked outlet within 10 seconds, the valve has closed Top up if necessary

13 Remove the closing down line adapter

14 If valve does not close after 5 applications, the cylinder must be de-pressurised Ensure vent valve is closed when not required to prevent contamination on fill line

15 Test all ports with leak detection spray, and test Schrader valve with water/soap solution If a minor leak is observed, it may be cured by tightening the offending components

16 Remove fill hose and filling adapter Leak test the outlet and attach anti-recoil cap Note: When leak testing outlet with spray, do not look directly into port Rather, examine quickly from an angle

17 Reset scales and record gross weight

18 Make certain all safety and protection caps are in place

19 Attach label to container stating the following information: Job number, Customer, Project, Container size, Fill weight, Gross weight, Date filled, and Type of agent

75


! CAUTION

When superpressurising, a pressure regulator must be used when the pressure source is a tank of high pressure gas

Container/ Valve Assembly leakage TestA leakage test is required for all filled SAPPHIRE valves and container assemblies after being left to stand in a bonded area for at least 24 hours Three test options are available The test equipment used for the first two test options are a leak detector and calibration gas, with a water bath being used for the third

Halocarbon Leak Detector Test

1 After 24 hours standing, the valve pressure gauge should be checked for pressure loss (refer to temperature correction chart to adjust for temperature change) The container and valve assembly should then be checked for leakage using the halocarbon leak detector unit

2 Testing should take place in an area free of Novec™ 1230 contamination

3 Take the halocarbon leak detector unit and calibration gas and within the Novec™ 1230 free environment, calibrate the unit

4 Adjust the halocarbon leak detector to gain a steady audible pulse, in free air, of about 2 to 4 pulses per second

5 Conduct a stability check by leaving the halocarbon leak detector for approximately 3 minutes in a clean air environment If the pulse rate is observed to stay within the range of 2 to 4 pulses per second, proceed to the repeatability check

If the stability check is inconclusive, repeat stability check in an alternative clean environment If stability problems persist, contact the technical support centre for instruction

6 The leak standard of 013 oz/year should be conditioned to a temperature of 20 °C +/-5 °C (68 °F ± 9 °F) for at least 24 hours

7 Conduct a calibration repeatability test

8 Remove the cap from the leak standard, screw the calibration nozzle into the outlet of the bottle and open the hand valve fully

9 Place the halocarbon leak detector probe into the calibration nozzle Within 5 seconds the pulse rate should start to increase and be a continuous tone within 15 seconds

10 Remove the probe from the nozzle and position the halocarbon leak detector unit away from the gas source The pulse rate should revert back to the original rate of 2 to 4 pulses per second within 15 seconds

11 Repeat test a further two times If repeatability test indicates that the unit is functioning within the set parameters, proceed to the container leak test

However, if the repeatability check is inconclusive, repeat check in an alternative clean environment If repeatability problems persist, contact the technical support centre for instruction Close the hand valve of the leak standard after use

Helium Leak Detector Test (Alternative Test)

Details of the procedure and equipment required are available from the Original Equipment Manufacturer (OEM) on request

Submerged Leak Test (Alternative Test)

The third option is a water bath test The charged sample(s) are placed in water bath for a period of no less than one hour A transparent collection apparatus is placed over each sample in a manner so as to collect any escaping Novec™ 1230 or nitrogen gas The one hour period begins after all air bubbles appearing in the device at the start of the test have been removed and the water bath is at the required temperature

Container Leak TestCarefully probe the container/valve assembly at all probes and openings Ensure that the probe is not brought into direct contact with any objects as this can lead to spurious results and ensure that the dwell time of the probe is sufficiently long (more than 5 seconds) to ensure any leak is detected Any significant and repeatable increase of the audible pulse rate should be taken as an indication of a leak and the container and valve assembly should be rejected

Once the leakage source has been rectified, the container and valve assembly should be subjected to a further leak test using the halocarbon leak detector unit
