5.0 Underground Fire Water Supply Mains and Interior Mains Located within Roof Trusses

5.1 Pipe

Pipe used in underground water mains (loops) for site fire protection shall be a minimum of ten inches in internal diameter. Six and eight inch pipes are not acceptable due to excessive friction loss characteristics. Water conditions shall dictate the schedule of pipe.

Required depth of cover for underground piping shall be in accordance with frost penetration in regional charts that indicate required depth of cover. Refer to latest edition of NFPA 13 (see attached chart on depth of bury).

Private fire service mains shall be looped or “gridded” to provide a dual water supply feed arrangement. NOTE: Interior fire water mains within roof trusses shall only be installed with approval from Corporate and GRC. Of major concern is the type of occupancies located beneath the interior fire main and for 20 feet in all directions. Not permitted are such occupancies as storage of combustibles, machining operations using combustible cutting oil, hydraulic oil system under pressure, etc.

Riser lead-ins shall be 8-inch to the alarm check valve. Process Mains (refer to Standard #101) shall be a minimum of 10-inches.

Sprinkler systems shall be designed so that one 8-inch lead-in main shall supply water to one sprinkler riser/system. Manifolded sprinkler risers shall not be permitted without written permission from Corporate.

Except for lead-in mains, water mains shall not be installed under buildings. Risers shall be located adjacent to exterior walls unless written permission is obtained from Corporate and GRC.

Pipe type shall be restricted to the following:

- Cast iron- Ductile iron- Steel- Polyvinyl Chloride (PVC) NOTE: Tracing tape should be installed per contract documents.

Piping fittings shall be restricted to the following methods:

- Welding- Mechanical fittings- Rolled Groove- Threaded (flanged)

NOTE: Meg-A-Lug or similar type mechanical fittings shall not be used unless thrust blocks are also used. GRC shall be contacted during design phase if such fittings shall be used.

Schedule 10 pipe is acceptable for use in sprinkler systems provided it is UL or FM approved. It must have a MIC coating applied by the Factory. If the pipe is painted in the field or shop, the pipe id markings , ie “MIC coated” are not legible. In this case the Chrysler AAME Project Engineer or a member of the Fire Team must accept the pipe prior to painting.

Standard 105 15

5.2.1 Cathodic Protection

If stray currents are suspected in the soil, all joints shall be bonded with low-resistance metallic ground connections. A corrosion engineer/consultant is required to provide information on the corrosiveness of the soil. NOTE: It maybe more cost-effective to just provide cathodic protection.

Methods, if required, for cathodic protection shall be sacrificial nuts, bituminous wrapping and coating, or a combination of the above. A minimum of two sacrificial zinc anode nuts per connection is required.

5.3 Thrust Blocks, Piping Anchoring & Trench Backfill

Pipe anchoring is required to prevent joints from separating at bends, tees, plugs, and changes in pipe diameter and hydrants due to unbalanced thrust created by water flow. Pipe anchoring is provided by either using thrust blocks, rods and clamps, or locked mechanical fittings. No Meg-A-Lug (or similar type) fittings shall be installed without thrust blocks. GRC shall be contacted during design phase if such fittings shall be used.

Thrust blocks are constructed of concrete and are cast-in-place. Sizes are determined by code. See NFPA 13 and 24. An acceptable method (sheet metal or plywood) shall be utilized to separate adjacent thrust blocks when valves or hydrants are in close proximity to each other.

The Fire Protection underground main installer or the Site General Contractor is responsible to photograph all poured thrust blocks and to number them according to a plot plan of the site with all hydrants, tees, valves etc labeled (these would be points where thrust blocks will be poured. As the job progresses these photos will be reviewed by a member of the Chrysler Fire Team. These printed photos shall be left on the job site in the Construction or AAME trailer.

An alternative is to leave all thrust blocks uncovered for viewing by a member of the Chrysler Fire Team.

Underground Fire Line Pipe Trench and Bury

Standard 105 16

The minimum clear width of the fire underground main trench shall be one foot greater than the outside diameter of the pipe. The maximum clear width of the trench shall not be greater than the pipe outside diameter plus 2 feet.

The depth of the trench is based on surface loads and frost penetration. A minimum of 24 inch depth of cover is required when frost is not a factor. Where frost is an issue then the pipe shall be buried 12 inches below the recommended NFPA frost bury. The depth of cover shall be measured from the top of pipe to finished grade.

The trench bottom shall be smooth and free from stones greater than 1 inch in diameter. Provide a minimum 4 inch bottom cushion of stone (A6) or Class 2 sand for the pipe to rest on. AAME site representative or on site Testing Engineering Company must be consulted to determine if stone or sand will be utilized for cushion and trench backfill.

If the soil is loamy or sandy A6 stone shall be used as the cushion and backfill material. A6 stone to be used must meet the ASTM D448 requirements for a Standard size A67 aggregate size. This is basically a mechanically crushed limestone with particle size not over 1 inch in diameter and minimum size of 3/8 inch. If the soil is clay then Class 2 sand may be used.

The cushion and backfill material shall be approved by AAME site representative and be reviewed by a Fire Team member prior to trench backfilling

5.4 Flushing of Underground Connections

All underground supply mains and lead-in connections shall be flushed to remove foreign materials before connection is made to sprinkler piping. Flushing shall continue until the water flows clear. Care shall be exercised during the flushing operation to assure that water flow will adequately drain without producing damage to surroundings. Corporate shall be notified at least one week prior to the start of any flushing. Representatives from Corporate and GRC must be present for all flushing.

Flow rates, in accordance with the latest edition of NFPA #13, Table 10.10.2.1.3 shall be used. They are as follows:

Flow Rate required to produce a Velocity of 10-fps (3 m/s) in pipes

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 100-psi. Pressure limiting disks shall not be used as a method to reduce pressure.

5.11Hydrostatic 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. Gauge(s) used shall be approved by member of Corporate and GRC.

No visible leakage shall be noted from the sprinkler piping. The amount of leakage for underground piping shall not exceed two quarts (1.89 liters) per hour per 100 gaskets or joints. This permissible leakage is not respective of (not directly proportional to) pipe diameter. The amount of leakage shall be measured by pumping from a calibrated container to maintain required pressure during the two (2) hour test. The amount of allowable leakage for valves is one fluid ounce per inch valve diameter per hour (30 milliliters) for each valve isolating the tested pipe section.

Standard 105 19

Hydrostatic testing of underground piping shall be performed before the trench is completely back-filled. Piping shall be covered between joints to hold the piping in place. Joints, however, shall be left un-covered so they can be observed for leakage during the test. When test “blanks” are used to isolate a portion of the system, only self-indicating types shall be used. Each blank, if used, shall be inventoried so that they can be totally removed from the system upon completion of testing.

Corporate shall be notified at least one week prior to the start of any hydrostatic testing. A representative of Corporate and GRC or an approved representative must be present for all hydrostatic testing.

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

5.12 Backflow Prevention and Low Suction Pressure Regulating Valves

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.

Types of backflow prevention are as follows:- Low Pressure Backflow Prevention Assembly- Double Check Valve Assembly- Check Valve- DetectorCheck Valve

A low suction pressure regulating valve may be required by the local authority having jurisdiction (AHJ) to prevent flowing water that will cause the residual pressure to drop below a predetermined rate, usually 20 PSI. These valves are not really backflow preventers.

Backflow preventors shall be FM approved. Install the backflow preventor, if required by the local AHJ, on the discharge side of the fire pump. The local AHJ may require the backflow preventor to be installed on the suction side of the pump.

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

All devices shall be located above ground.

7.0 Roof Decks

7.1 General

Roof decks shall be minimum Class I-90 insulated steel deck for wind uplift and FM Class 1 for flame spread.

FM Global approves a number of special roof insulation and roofing “systems”. These systems are used to provide components of the roof deck, including vapor barriers, insulation, wind up-lift resistance and adhering material that provides fire safety and wind resistance.

The FM Approval Guide and Data Sheet 1-28 and 1-29 shall be reviewed when considering types of roof deck for an installation. Items such as ground roughness and distance from a coastline shall be considered in determining the type of roof system.

Approved proprietary roofing systems and components shall be provided in accordance with the Factory Mutual Approval Guide.

All thermal barrier boards, including gypsum board, shall be fastened in accordance with FM Data Sheet 1-29.

7.2 Roof Coverings

Roof covering range from combustible wood shingles with no fire retardant treatment to coverings that are effective against severe external fire exposure. Well-designed fire resistive roof coverings can minimize the likelihood of fire spread from one building to another.

7.2.1 Roof Covering Classifications - Factory Mutual Global

An insulated steel deck roof is designated FM Class 1 when the roof is constructed with deck components that have met Factory Mutual Global limitations on heat release rate during testing.

When heat release from a tested roof assembly exceeds those limitations, the roof is designated FM Class 2.

7.2.2. Roof Covering Classification - NFPA

Three classes of fire resistive roof coverings in accordance with NFPA are as follows:Class Coverings: Include roof coverings that are effective against severe fire exposures. These coverings are not readily flammable, do not “carry” or communicate fire, have a high degree of fire protection to the roof deck, do not slip from position and possess no flying brand hazard. They do not require frequent repairs to maintain their fire retardant properties.

Class B Coverings: Include roof coverings that are effective against moderate fire exposures. These coverings are not readily flammable, do not readily “carry” or communicate fire, have a moderate degree of fire protection to the roof deck, do not slip from position and possess no flying brand hazard. They may require repairs to maintain their fire retardant properties.

Class C Coverings: Include roof coverings that are effective against minimal fire exposure. These coverings are not readily flammable, do not readily “carry” or communicate fire, have a slight degree of fire protection to the roof decks, do not slip from position and possess no flying brand hazard. They require repairs or renewals to maintain their fire retardant properties.

Building codes commonly require Class “A” or “B” coverings wherever fire resistive construction is required or within requirements of local codes. Class “C” roofing is appropriate for other buildings. Many municipalities specify Class “C” as the minimum standard for roofing.

Chrysler LLC will only accept Class “A” roof covering installations and Factory Mutual Class 1 approved roofing systems unless deviations are approved by Corporate and GRC.

Standard 105 24

7.3 Construction

Insulated steel deck is constructed by first securing rigid insulation board to the upper surfaces of the deck with insulation fasteners. A waterproof covering is then installed above the insulation. The built-up roofing type is three to five piles of roofing felts adhered to the insulation and to each other with hot tar or asphalt.

The single-ply membrane covering is also widely used. The ply is fastened to the deck and adhered to the insulation or loosely laid and covered with stone ballast.

When a vapor barrier or retardant is needed, this single ply sheet can be placed directly on the deck, or in some cases. Adhered to a minimum thickness insulation board mechanically fastened to the deck.

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

Any roof decks not covered in the above sections shall be referred to the Corporate Fire Prevention Engineer for approval and comments such as standing seam, single ply membrane etc.

7.4 Standing Seam Roof Systems

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

Standard 105 25

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 firewall range from three to six hours.

Fire partitions subdivide a floor or building area and extend from the floor to the underside of the floor above. Fire partitions may be constructed of non-combustible, limited combustible or protected combustible material and shall be attached to and supported by structural members having fire resistance at least equal to the requirement of the partition. A fire partition normally possesses less fire resistance than a firewall and does not extend from the basement through the roof, as does a firewall. Fire resistance ratings for partitions range from one-half to two hours.

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

Exterior walls, interior partitions and floor/ceiling assemblies are components that define the architectural layout of rooms in a building. These components are used to provide privacy, security, and protection from the elements and noise control. They also provide fire protection by delaying or preventing fire from spreading from one room to an adjacent room. IF THESE WALLS HAVE URETHANE FOAM INSULATION AND ARE OVER 30 FEET HIGH THEN THEY MUST BE FACTORY MUTUAL GLOBEL APPROVED. THIS REQUIREMENT IS FOR EXTERIOR AND INTERIOR WALLS.

The effectiveness of a barrier in preventing flames from moving from one room to another depends upon the fire resistant construction of the barrier, the fuel load in the room, applied loading on the structural components, the construction features and the effect of openings and penetrations in the barrier.

The most common cause of fire movement from one room to an adjacent room is through unprotected openings in barriers. Code requirements and heavy duty construction are often rendered ineffective because of uncontrolled openings in a partition, i.e., doors, windows, grilles, ducts, and other openings in conjunction with a lack of protection of openings.

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

All exterior metal foam (sandwich) panel walls shall be Factory Mutual approved when used for walls over 30 feet in height

8.2 Fire Resistance

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

Fire resistance ratings are determined by subjecting the barrier assembly to standard fire tests. Fire resistance is the endurance time converted to duration in hours that is established by recognized standards. Both combustible and non-combustible barriers can obtain fire resistance ratings from fire tests. Fire doors and other protected openings shall have a fire resistance rating equal to or exceeding the rating of the wall (partition).

Fire resistance of walls and partitions will delay or prevent flames from moving horizontally from one room to an adjacent room. These assemblies are tested in accordance with NFPA #251, “Fire tests for Building Construction and Materials”.

Standard 105 26

Large manufacturing and warehouse buildings are sub-divided into fire areas to limit the spread of fire. Horizontal fire spread is limited by distance between building (as required by code) or by firewalls. In multi-story buildings, vertical fire spread from one story to another is limited by the floor construction and by wall enclosures around stairways, elevator shafts and other horizontal and vertical openings.

8.3 Application

Subdivision of a building through use of barriers is intended to independently limit property loss from a single fire. However, fire suppression systems supplement passive barriers to provide an adequate fire protection system. If sprinkler protection is impaired, reliance must be placed on passive barriers and manual fire fighting operations for fire containment.

Area housing hazardous processes, equipment or materials shall be isolated from surrounding occupancies. Paint mix rooms and paint operations shall be separated from metalworking operations and other fuel and heat sources, flammable-liquid storage tanks from main-plant buildings, and storage from manufacturing operations. Equipment or services of vital importance to uninterrupted production shall also be separated from the fire or explosion hazards of surrounding buildings or occupancies. Power-generation equipment shall be located in a segregated building. Power transformers and switchboards shall be located in fire-resistive cutoff rooms or located outside. Storage of records and tracings shall be in special vaults.

8.4 Parapets

Parapets prevent passage of fire over firewalls when the roof deck is combustible. Parapets shall extend at least 30 inches above a combustible roof and shall be of non-combustible construction. Parapets shall be an extension of the firewall, designed to break the continuity of embers and radiant heat from spreading to an adjacent fire area. Class I insulated metal roof decks are not sufficiently combustible to require parapets.

Standard 105 27

9.0 Smoke & Heat Venting

9.1 General

Ventilation is the planned and systematic removal of heat, smoke, and fire gases from a building. Ventilation may be required in accordance with rescue efforts in order to protect occupants from smoke and heat and to provide visibility and tenability during rescue operations.

Emergency exhaust (heat & smoke) vents shall be provided in storage areas and other high heat release areas only when required by local codes.

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

Emergency exhaust wall vents shall be provided in conjunction with, but not in place of, fire rated walls and fire detection and suppression systems.

Vents, where required, shall operate both automatically and mechanically. Automatically operated vents shall be connected to the building/plant security system and designed to operate upon activation of the fire alarm system or sprinkler system within that zone.

Vents shall be equipped to operate mechanically by provision of a fusible link. This link shall be one temperature rating higher than the existing sprinklers in the area. For example, if sprinklers are 286°F, use 360°F fusible links for heat and smoke vents.

Heat and smoke venting shall be provided at a ratio of 1 square foot per 30 square feet of room floor area (1:30) or as required by local codes.

A powered exhaust option for up to 50 percent of required heat and smoke venting may be provided at a ratio of 300 cubic feet per minute of exhaust volume per square foot of heat and smoke venting (300:1).

Dampers and smoke detectors shall be installed in ductwork/stacks in accordance with the authority having jurisdiction.

9.2 Vent Types

Heat and smoke vents are typically 16 to 100 square feet in area. Automatic vent operation is of two types, i.e., fusible link type or “drop out” plastic. The fusible link type consists of a metal housing with lids that depend upon a temperature rated fusible link to trip the lid mechanism. The drop out plastic type depends upon a temperature sensitive, transparent or translucent thermoplastic dome that deforms from its setting and falls out of the roof when heated beyond its temperature rating. Vents designated for manual operation (in conjunction with automatic operation) are constructed with metal lids to resist elevated fire temperatures and may be opened from the floor with wires and cables.

9.3 Explosion Relief Venting

Explosion relief venting (for the Paint Mix Room only) shall be provided at a ratio of 1 square foot per 50 cubic feet of volume (1:50). Explosion relief venting can be designed into either the roof or wall.Explosion relief venting shall relieve at 20-25 pounds per square foot, but in no case less than the design wind load pressure.

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

9.4 Draft Curtains, if required by code.

Only in large buildings that are not sub-divided by walls or partitions, draft curtains are important for prompt and positive actuation of vents because they bank up heat within the curtained area and limit the spread of heat and smoke to the zone or area of fire origin.

Standard 105 28

Draft curtains are constructed of any substantial non-combustible material that will resist the passage of smoke. Draft curtains are required only if needed due to local codes or in conjunction with ESFR sprinkler heads.

The depth of draft curtains should be selected to correspond with the design depth of the smoke layer. As a guideline curtain depth should not be less than 20% of the ceiling height to prevent spillage of smoke under the curtain. Draft curtains used in conjunction with ESFR sprinklers only need to be 2 feet deep.

The distance between draft curtains shall not exceed eight times the ceiling height so that smoke control and actuation of roof vents within the curtained compartment will be effective. The distance between draft curtains shall be not less than two times the ceiling height, unless the draft curtains extend to a depth of at least 40% of the ceiling height.

Standard 105 29

10.0 Sprinkler System Requirements

10.1 Classification of Occupancy

The function (use) of a building as directed by the building code and the authority having jurisdiction is the determining criteria for designing a sprinkler system as the system must be designed to protect against the hazards inherent to the type of occupancy. Three main classes of occupancy are recognized in accordance with NFPA. Sprinkler discharge densities, water supply requirements, spacing of sprinklers and schedules of pipe sizes (if a pipe schedule is used) differ for each hazard.

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

Light Hazard: Includes occupancies where the quantity and combustibility of material is low, and fires with relatively low rates of heat release are expected. This class includes office buildings and computer facilities.

Ordinary Hazard: This class includes ordinary mercantile, manufacturing and industrial properties. This call is divided into two groups:

- Group I includes occupancies or portions of other occupancies where the combustibility is low, quantity of combustibles is moderate, stockpiles of combustibles do not exceed 8 feet (2.4 meters), and fires with moderate rates of heat release are expected.

- Group II includes occupancies or portions of other occupancies where quantity and combustibility of contents is moderate to high, stockpiles do not exceed 12 feet (3.7 meters), and fires with moderate to high rates of heat release are expected.

- Extra Hazard: This class includes occupancies or portions of occupancies where quantity and combustibility of contents is very high and flammable and combustible liquids, dust, lint, or other materials are present, introducing the probability of rapidly developing fires with high rates of heat release. Extra hazard occupancies involve a wide range of variables that produce severe fires. The following shall be used to evaluate the severity of Extra Hazard (E. H.) Occupancies.

- Group I involves an E. H. occupancy with little or no flammable or combustible liquids. - Group II involves an E. H. occupancy with moderate to substantial amounts of flammable or

combustible liquids or where shielding of combustibles is extensive.

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

Example of Ordinary Hazard Group II occupancies are machine shops, metal working, repair garages, wood machining, tire manufacturing, etc.

Examples of Extra Hazard Group I occupancies are some aircraft hangars, die casting, upholstering with plastic foam, rubber reclaiming, printing with inks with flash points below 100°F, etc.

Examples of Extra Hazard Group II occupancies are flammable liquid spraying, flow coating, open oil quenching, plastic processing, varnish & paint dipping, etc.

While classification of occupancies into three broad categories serves as a basic guide, each individual area of occupancy (hazard) shall be evaluated, as it may be more severe than the criteria with which the building sprinkler system is designed, thus requiring review and up-grade of the fire protection system.

In each of the three building classifications, the system may be either follow an appropriate piping schedule or the system may be hydraulically calculated. Hydraulically calculated systems are required on all new Chrysler LLC facilities/buildings and are preferable for renovated facilities.

Sprinkler design criteria for buildings over 30 feet in height must be established by Chrysler LLC Corporate Fire Prevention Engineer and Loss Prevention Service Provider GRC.

Ductwork shall be designed for a minimum of 30-gpm for the most remote 10 sprinklers. Sprinkler protection is requirement in ductwork 100 square inches of cross-sectional area and above whenever the ducts are combustible, handle solvent laden air, are a pathway for combustible dusts or particulate matter or where combustible residues can collect on the ductwork interior. (Basically ductwork 10” in diameter and larger).

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

NOTE: Use 100-psi as maximum design pressure at the base of riser for any sprinkler system. For office occupancies, this maximum design pressure may be increased to 110-psi with approval obtained from the Corporate Fire Prevention Engineer.

Non-crimped (welded) seamsPlastic parts on vehicles limited to gas cap (cover)No combustible tape, paper, or plastic sheeting on vehiclesIn-direct fired burner unit

- Combustion safeguards approved by the HPR insurance carrier

10.3 Sprinkler Heads (see table)

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

Early Suppression/Fast response (ESFR) sprinklers are becoming a widely used concept in moderate and high hazard environments and are acceptable for use within Chrysler LLC facilities/buildings. ESFR sprinklers have an extra large orifice and deflector and are designed to produce larger water drops that quickly pierce a rapidly developing fire, particularly rack storage facilities. ESFR sprinklers also have a sensitive fusible element that provides fast response to heat. Installations involving ESFR sprinklers must follow the guidelines within Factory Mutual Data Sheet 2-2 and NFPA #13, latest editions.

Guidelines for ESFR sprinkler applications shall be found in the latest version of FM Global Data Sheet 2-2 and NFPA #13, latest editions. General guidelines shall be as follows:

14.3.2.1 Carbon Dioxide Protection

Carbon Dioxide Fire Protection System Minimum Requirements

Scope:

This section contains minimum requirements for carbon dioxide fire protection systems. It includes only the basic essentials to make the standard workable in the hands of those trained & skilled in this field. Only those with the proper training and experience shall design, install, inspect, and maintain this equipment. Examples of proper training would be factory certification by a particular system manufacturer.

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

Systems:

Two major type carbon dioxide systems used at Chrysler LLC facilities – Total Flooding systems and Local Application systems.

Total Flooding System – consists of a fixed supply of carbon dioxide normally connected to fixed piping with nozzles arranged to discharge carbon dioxide into an enclosed space or enclosed space around the hazard.

Local Application System - consists of a fixed supply of carbon dioxide normally connected to fixed piping with nozzles arranged to discharge carbon dioxide directly on the burning materials.

Agent Storage Containers:

Carbon dioxide extinguishing systems use either high-pressure storage units (cylinders at room temperature usually in 75 or 100 lb. capacity for industrial applications) or low pressure storage units (large refrigerated tanks – ¾ ton or larger). Ansul’s Mini-bulk low-pressure system range from 500-lb. to 1,500-lb. Capacity and are considered low- pressure systems.

System storage container selection is primarily based upon economics that is strongly influenced by hardware requirements. Typically, selecting a low-pressure storage container becomes more favorable as system carbon dioxide requirement increase. Multiple timed discharges are also possible with low-pressure storage containers.

High Pressure – Indicates that the carbon dioxide is stored in pressure containers at atmospheric temperatures. At 70 F, the pressure in this type storage is 850 psi.

Low Pressure - Indicates that the carbon dioxide is stored in pressure containers at controlled temperatures, at 0 F. At 0 F, the pressure in this type storage is 300 psi.

Extinguishing Mechanism:

Carbon dioxide extinguishes a fire by oxygen depletion and reducing the oxygen content from the normal 21% in air to 15%. This will extinguish most fires. The cooling effect created by a carbon dioxide discharge is of little significance. Since it is a gas, it will penetrate and spread to all parts of a hazard. Carbon dioxide does have a density about 50% greater than the density of air.

Applications:Standard 105 42

Based upon property insurance requirements and Chrysler LLC Corporate Standards, carbon dioxide shall not be a replacement for providing automatic sprinkler protection, unless approved by the Chrysler LLC Corporate Fire Prevention engineer. A carbon dioxide fire suppression system can be used to provide supplemental fire protection in the following areas:

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

NOTE: Carbon dioxide protection can be omitted within horizontal ductwork and oil mist collector if all three of the following conditions are met and approved by local AHJ:1). There is a damper on all vertical ductwork interlocked to close automatically prior to discharge of the carbon dioxide system.2). All horizontal ductwork and oil mist collector(s) have automatic sprinkler protection. Also, the ductwork must be designed to hold the additional weight of the sprinkler water discharge.3). Carbon dioxide system is designed to protect the entire machine enclosure and vertical ductwork. Within unmanned pits such as caster/camber, roll test, BSR pits, etc. (if manned pits, HFC-227ea

(FM-200) shall be used) Within normally unmanned rooms, if approved by the Corporate Fire Prevention engineer. An

example is a dynamometer test cell. Beneath raised floor of a data/computer room(s). Heat-treat operations using combustible quench oil (local application).

Sequence of Operation using fixed temperature heat detectors:

Rooms (dynamometer, engine test, etc.): Minimum two detectors Activation of alarms within room, outside room and on Release Control Panel upon activation of

1st detector. Activation of all interlocks upon activation of 1st detector. (?) 1st or 2nd? Discharge of carbon dioxide gas after a 30 second pneumatic time delay upon activation of 1 st

detector. Pneumatic siren or sirens

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

Machinery Enclosure when protected is required: Minimum two detectors Activation of alarms on equipment and Release Control Panel upon activation of 1 st detector. Activation of all interlocks upon activation of 2nd detector. Discharge of carbon dioxide gas upon activation of 2nd detector with no time delay.

NOTE: Sequence of Operation for each protected machinery enclosures must be reviewed on a case-by-case basis due to various factors that may apply. It is critical that contractor contact Chrysler LLC Corporate Fire Prevention Engineer and Loss Prevention Consultant prior to engineering the protection so that any factors can be reviewed prior to designing the protection.

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

The discharge of carbon dioxide in fire-extinguishing concentration creates serious hazards to personnel, such as suffocation and reduced visibility during and after the discharge period. In any use of carbon dioxide, consideration shall be given to the possibility that personnel could be trapped in or enter into an atmosphere made hazardous by a carbon dioxide discharge. In addition to the protected space, consideration shall also be given to the possibility of carbon dioxide drifting and settling into adjacent places outside of the protected space. Consideration shall also be given to cylinder storage areas where the carbon dioxide can collect in the event of a discharge from a safety relief device of a storage container. Suitable safeguards shall be provided to ensure prompt evacuation, to prevent entry into such atmospheres, and to provide means for prompt rescue of any trapped personnel. Personnel training shall be provided. Pre-discharge alarms shall be provided in all cases unless specifically

Standard 105 43

waived in writing by Corporate Fire Prevention and GRC and other authorities having jurisdiction.

To prevent accidental or deliberate discharge, a supervised “lock-out” valve as defined in NFPA #12 shall be provided when persons not familiar with the systems and their operation are present in a protected space. This lock out valve shall be specifically addressed in the release control panel and report an individual point from the release panel to the plant alarm system in the form of a dry contact. Any employee or vendor representative shall notify Plant Security before inspecting, modifying, and/or servicing any carbon dioxide system or systems. Lockouts that utilize software only are not acceptable/permitted. Pneumatic time delay (in most cases) and pneumatic siren are required.

Local application systems shall be locked out when persons are present in locations where discharge of the system will endanger them, and they will be unable to proceed to a safe location within the time-delay period for the system. When protection is to be maintained during the “lockout” period, a person(s) shall be assigned as a “fire watch” with suitable portable fire-fighting equipment or means to restore protection. The fire watch shall have a communication link to a constantly monitored location. Authorities responsible for continuity of fire protection shall be notified of lockout (and will lock the system) and subsequent restoration of the system.

Plans & Approvals (Also refer to 2000 Edition of NFPA #12, Section 1-7):

Plans and calculations shall be submitted and approved by the local Authority Having Jurisdiction (AHJ), Global Risk Consultants (GRC) and other agencies as required by Chrysler Security Services before beginning the installation.

Standard 105 52

16.0 Fire Alarm Systems & Release Control Panels

16.1 System Types

Fire protection signaling systems are classified according to the function they are expected to perform. Types of systems are as follows:

16.1.1 Local System

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

The basic features of a local protective signaling system are:- A control panel.- A primary (main) power supply that usually is the local power service.- A secondary (stand-by) power supply (batteries).- Initiating devices such as detectors, manual fire alarm boxes, water-flow alarm devices, and

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

A local alarm system may not relay a signal automatically to a central station or fire department. Therefore, when a local alarm “sounds” and the system is not connected to a central station or fire department (typically in office buildings) personnel must notify the fire department.

16.1.2 Auxiliary Systems

An auxiliary protective signaling system has circuitry connecting alarm initiating devices to the municipal fire alarm system (fire department) either through a master fire alarm box or through a dedicated telephone line connected directly to the municipal communication central switchboard. The signal received by the fire department is the same received when someone manually activates any municipal fire alarm box.

16.1.3 Remote (Central) Station Systems

A remote station signaling system has an alarm signal that is received at a remote location that is attended by trained personnel 24 hours a day (constantly attended). The receiving equipment is located at a facility other than the fire department, such as a police station or telephone answering service. The signal is transmitted over a leased telephone line, and is indicated audibly and visually at the remote station. Remote station personnel notify the fire department of the alarm.

16.1.4 Proprietary Systems

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

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

The station (location) receiving the fire alarm signal in a proprietary system is operated by personnel with a proprietary interest in the protected buildings (on-site).

Central station system is staffed by operators who perform the service for a fee and have no proprietary interest in the protected buildings.

The proprietary system receiving station is a security office within or near the building (or group of buildings) protected by the system.

Many existing proprietary systems have separate initiating device circuits for each building zone or subsection, similar to the local, auxiliary, and remote station systems. With the increasing use of electronics, proprietary systems for larger buildings have signals multiplexing and built-in computer

Standard 105 53

systems. These systems receive all signals from the building over one or more pairs of wires and determine the exact location of a fire by use of different frequencies or digitally coded information transmitted over the multiplex system.

16.2 Points to Alarm

Points to alarm include the following:

- Water flow switches (vane type and pressure switch)The alarm contractor shall make the initial setting on the waterflow alarms. The maximum time for the waterflow to received alarm at the proprietary or central station shall be no longer than 90 seconds.

- All waterflow alarms must be able to be tested. This is accomplished by piping the alarm line to a fixed drain or into the water wash in a paint shop. If the above is not accessible then a 5/8” quick disconnection to accept a 5/8 inch garden type hose.

- Valves (exterior valves, SCV, PIV, Wall valves do not require tamper switches. A means to lock the valves shall be supplied. Lock NPN code 35-610-0864

- Detectors (smoke, heat, flame)- Manual pull stations

Fire Pumps - NOTE: P = Alarm at control panel F = Alarm received at remote location- Fire pump running (started) = F- Switch off Automatic = F- Loss of operating electric power = P- Phase reversal on line side of the motor = P- Low fuel supply = P provide a low fuel switch to alarm at the 5/8 level of the diesel

fuel tank- Controller main switch in “off” or “manual” position = F- Low lubricating oil pressure = P- High engine temperature = P- Battery charger failure = P- Overspeed= P- Low pump house temperature (42 oF) = P- Suction supply water level below normal = P- Suction supply water low tank temperature (42oF ) = P

If these alarms have a common audible signal, each condition shall be visually shown (individually) at the fire pump use controller, and at the Plant’s Proprietary Alarm Panel.

- Special Suppression Systems- Discharge of Agent- System trouble

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

- Trouble Signal - A “trouble signal” is given when a fault occurs in a supervised (monitored) device or circuit of a protective signaling system. Circuits that are normally supervised included main power, alarm initiating and alarm signaling circuits. Trouble signals for remote station auxiliary systems are received at a central supervisory station. In local and proprietary systems, trouble signals are “sounded” in areas where personnel are normally present.

- Supervisory Signal - In sprinkled occupancies, a sprinkler “supervisory signal” is given when a critical component in the sprinkler system is in an abnormal condition. These conditions include such factors as low water service pressure, loss of power to a fire pump, closing of a water supply valve, low water level of a water supply tank, or near freezing temperature in an outdoor water supply tank. Local and proprietary system supervisory signals are usually “sounded” in areas where personnel are normally present. Remote station and auxiliary system supervisory signals are received at the receiving station.

- Alarm Signal - When a fire is detected, an alarm signal is transmitted upon operation of either a manual or automatic initiating device (manual pull station, suppression system, or detector).

Although alarm signals generally involve the sounding of audible signals throughout a building, signals may be “sounded” only in the vicinity of the immediate fire area of large

Standard 105 54

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

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

- Non-coded Signal - Alarm signals produced by a fire alarm system may be continuous sounding throughout the protected area. When these devices are “sounded” continuously, the system is “non-coded”.

- Coded Signal - When devices are sounded intermittently in a prescribed pattern, the system is referred to as a “coded” system. Coded signal systems vary in size, depending upon the size and needs of the alarm system.

Signals can be audible or audible/visible.

Because public buildings must be accessible to handicapped people, fire alarm system must include visual alarm signals to alert occupants with impaired hearing and in high noise areas by use of a combination horn/light unit. (Refer to American with Disabilities Act guidelines)

The fire alarm system shall comply with requirements of the latest edition of NFPA Standard #72 for Protected Premises Signaling Systems. The system shall be electrically supervised Class ‘A’ Style 6 and monitor the integrity of all conductors.

The system contractor/supplier is responsible for programming (reprogramming) all points at the head end. The point descriptor shall be obtained from the local Wakenhut (G4S) Site Security Manager.

Special suppression systems shall send a signal to the head end on the 1st alarm signal. This signal shall be received as an “alarm” point and not a “trouble” signal.

16.2 Evacuation Systems

Evacuations tomes shall have a sound level at least 15 dB above the ambient sound level or 5 dB above the maximum sound level having a duration of at least 60 seconds whichever is greater, measured 5 feet above the floor. The sound level shall not exceed 115 dB.

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

Fire/evacuation – Provide three (3) 0.5 seconds tones spaced 0.5 seconds apart followed by a 1.5 second pause. This pattern must be repeated for at least three (3) minutes.

Take Cover/Seek Shelter – Provide a continuous bi-tone (high/low) oscillation for at least three (3) minutes.

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

All tones must be manually selectable form the head end. These tones must be distinct and not used for any other plant signaling systems.

The evacuation system's software shall be programmed such that if communication between a field panel and the head end is lost, the field panel while going into the "degrade" mode DOES NOT activate the evacuation alarm if a signal is received at the "degraded" panel.

In response to this loss of communication, local Plant Security is required to send a person to monitor the "degraded" panel until repairs have been made and or communications is reestablished with the head end.

This procedure shall be followed when working with a "Class B" system. If the system is a style 6 (or 7) or "Class A" system, then the loss of communication is recorded, but the network panels will continue to function. Alarms can still be received and acknowledged from the panel in the security console room. Repairs shall be made as soon as possible to the system as required.

Standard 105 55

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, local Plant Security and Corporate. The local authority having jurisdiction (AHJ) involvement shall be determined on a plant by plant basis by local Plant Management. A sound meter shall be utilized for all speaker testing.

16.3 Fire Release Panels

The following is a basic description of Release Control Panels (RCP) acceptable for use at Chrysler LLC facilities for the release of a fire suppression agent such as HFC-227ea (FM-200), HFC-125 (ECARO), carbon dioxide, , dry chemical, high-speed deluge, etc. NOTE: Since these panels can be used to activate a fire alarm, the manufacturer commonly refers to these as Fire Alarm Control Panels (FACP). When used to release a fire suppression agent as well as activate a fire alarm, refer to the given panel as a Release Control Panel and the panel used to activate the building fire alarm (evacuation) system as the Fire Alarm Control Panel. At a given facility, several RCPs may be connected to one FACP.

The Release Control Panel is only one component of the entire fire suppression system. The name of the given panel or the manufacturer is generally used to describe the entire system. It takes several devices/components to makeup a fixed fire suppression (protection) system. These include such devices as manual pulls, smoke detectors, heat detectors, flame detector, strobes, horns, speakers, modules, relays, cable, conduit, extinguishing agent, cylinders, tanks, batteries, etc.

Normally the Release Control Panel is located within a large painted red cabinet/enclosure that also contains various relays, modules, switches, batteries, power supply, battery charger, wiring, etc. This panel must be located outside the protected space.

The Release Control Panel contains the CPU (microprocessor).Addressable Release Control Panels have a keypad that can be used to program the panel.

Release Control Panels contains relays and terminal blocks used to attach wires connected to the power supply, Notification Alarm Circuits (NAC), Initiating Device Circuits (IDC), and Signaling Line Circuit(s), etc. The RCP contains and executes all control-by-event programs for specific action due to detection of a fire. It stores all the system’s operational parameters (programmed) in non-volatile memory (different from the history memory (buffer)). The RCP contains the real clock for the date and time used for the history memory to display and print “alarm” and “trouble” events.

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

The releasing control panel shall be UL listed and Factory Mutual approved, per panels listed in Section 4.4 or DaimlerChrysler approved equal. The control panel shall provide power for all fire sensors with twenty-four (24) hour battery backup. The control panel shall have the following features:

- The control panel shall be capable of linking up to a minimum of one hundred twenty-seven (127) addressable devices per circuits.

- The control panel shall provide a separate custom thirty-two (32) character message for each addressable device.

- The control panel shall provide a non-volatile memory that retains all alarmsor trouble conditions in the event both primary and secondary power is lost. Memory shall be

accessible through use of an IBM Compatible Personal Computer.

The control panel shall be field programmable using an IBM Personal Computer without reprogramming of computer chips or by other means.

Standard 105 56

Electrical conduits shall only enter fire release control cabinets/enclosures from the side. Penetrations to the fire release control cabinet enclosure shall only be performed by the fire release control panel installer or under their supervision.

A smoke detector is not required over the release control panel as Chrysler has determined that this panel is not part of the building fire alarm system. However, if the AHJ requires this detector, then it shall be wired (separate address) to the building fire alarm system, and not the release control panel.

16.5 Proprietary Products

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

Equipment Manufacturer

Cla-ValveModel 7100KH Cla-Val Company

Bete NozzleTF Series Bete Fog Nozzles, Inc.

IR3 DetectorX-3301A21W1 Detector Electronics/Detronics (Preferred Unit)

IR Fiber Optic DetectorPM9-SBE Detector Electronics/Dual Spectrum

Detector Control PanelEagle Quantum Detector Electronics/Detronics (Preferred Unit)Cheetah/Cheetah Xi Fike Corporation

Some definitions are in order to explain the differences in Release Control Panels and fixed fire suppression systems.

Addressable Release Control Panel: A Release Control Panel that has the ability to display the programmed address (name) of the device or devices that have been activated due to a fire condition, manual action, or electrical “short” or “open”, etc. Each device associated with the system is assigned an address (name) which when programmed correctly is identified by the microprocessor of the RCP. Should an alarm or trouble condition occur, the assigned address of the device is known rather than just a zone that contains multiple devices. NOTE: Devices connected to an addressable RCP must be approved for use with that panel. A conventional device will not work on an addressable RCP.

Conventional Release Control Panel: A Release Control Panel that does not display the name of the device that has been activated or “trouble” condition but only displays the zone that the device is connected to. Generally, rather than a readable display, only a light (LED) on the RCP is lit. If a zone goes into a “trouble” condition, each device and associated connections and wiring must be examined until the device, connection, and/or problem with the wiring is discovered and repaired.

Non-volatile History Buffer: Memory of previous activities will not be lost upon loss of all electrical power sources i.e., AC or battery. All U. L. Listed addressable RCP have a non-volatile history buffer that records all events of the panel including alarm and trouble conditions, loss of A.C. power, loss of battery charge, low battery condition, etc. Some conventional RCP do have a non-volatile history.

The three proprietary Detector Control Panels (really RCP’s) are addressable RCP with non-volatile history buffer (memory). Conventional RCP are not acceptable not only due to the downtime required to trace the entire system to discover (and repair) the source of the trouble but only an addressable RCP can be used to cause the agent discharge or not discharge based upon the programming of the devices. Many RCP used within Chrysler LLC facilities are connected to two forms of fire suppression (gas agent and a water spray). Only an addressable RCP can be used to discharge one agent over the other, or discharge both with a time lag based upon how a device is programmed (based

Standard 105 57

upon its assigned address). Addressable RCPs are completely field programmable and configurable from the front panel keyboard.

For the AME group, generally the machine manufacturer subcontracts the fire suppression system(s) to a Chrysler LLC approved and licensed fire protection contractor. The fire protection contractor used is based upon what panel manufacturer’s equipment is already at the plant. For a new plant, this is not an issue unless the new facility will under the control of an adjacent facility that has a preference for a particular manufacturer.

If the bid is an open bid, a few pre-qualified fire protection contractors bid the project(s) and generally the contractor with the lowest bid gets the work.

Key manufacturers that make fire suppression systems and equipment used at Chrysler LLC facilities are Detector Electronics/Detronics, Notifier, Fike, Fenwal and Siemens.

Once a fire protection contractor is contracted, the fire suppression system installed will be a system using equipment from the distributor of the fire protection contractor. There are some devices that may be used regardless of the distributor. But if a Fike RCP (for example) will be installed, the associated devices used in the installation will be manufactured by Fike (or compatible with Fike).

There are dry contacts (relay) within the RCP that are connected to various interlocks related to the machining operations. Before a gas agent is discharged, certain operations are interlocked to shutdown. Electrical power to the protected machine/equipment is shut-off using a dry contact. Generally the systems are designed to allow a machining sequence to be completed before the electric power is disconnected. This interlock includes the cutting oil pump(s).

Dampers within exhaust ductwork will be interlocked to close using a dry contact. Hydraulic pumps are interlocked to shut-off before the gas agent is discharged. Also, air handlers and/or oil mist units are interlocked to shut-off before the agent is discharged.

SINGLE HAZARD PANELS (SHP)

SHP’s are normally not acceptable for any Chrysler LLC installation. Written permission must be obtained in advance from the Chrysler LLC Corporate Fire Prevention Engineer. NOTE: A contractor shall not automatically bid using a SHP unless the Chrysler LLC specifications specifically state that a SHP can be used. Bidding a project using a SHP without specific written instructions shall require the contractor to supply an addressable Release Control Panel at no additional cost to Chrysler LLC.

Items that will be considered upon accepting a SHP for a particular project are:1). Number of detection devices required, including detector required over Release Control Panel.2). Fact that SHP have no history buffer which might be critical to have for a particular application.3). SHP panels usually only have two detection circuits, both are usually required for providing sequential zoning within the room or equipment. Therefore, additional cost may have to be calculated for installing the smoke detector over the SHP to the building’s fire alarm system. 4) By-pass switches within an enclosure that can be locked with a Chrysler LLC provided padlock will required. Individual switches will include, as a minimum - AC-power, DC-power, detection circuits, any interlock circuits, and purge fan control circuit.

If a SHP is acceptable to the Chrysler LLC Corporate Fire Prevention Engineer, only this engineer shall approve the manufacturer and model of the SHP to be installed.

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

Interlocks connected by software shall comply with the additional requirements:1. The shutdowns are programmed in the PLC safety logic 2. Access to the safety logic is by password only by the system manufacturer3. Any changes to the safety logic must be verified and tested by Corporate Fire and GRC

17.2 Paint Mix Room

Operation of paint mix room equipment shall be interlocked to shutdown upon a fire alarm signal by means of a detector, manual pull station or water-flow switch protecting the paint mix room. This includes mixers, paint and solvent supply and mechanical ventilation equipment.

17.3 Paint Spray Booth

Paint spray booth equipment, i.e., paint lines, paint spray cabinets and automation shall be interlocked to shutdown upon activation of a fire detector, manual pull station or water-flow switch from a water spray (deluge) fire suppression system.

The following equipment shall be interlocked to shutdown upon actuation:

Assembly (Conveyor) LineSupply and Return Ventilation – Only Upon Booth Sprinkler OperationPower Supply to Paint Spray Booth Painting Equipment

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

17.4 Computer Room

Computer and ventilation equipment shall be interlocked to shutdown, and ventilation dampers interlocked to close upon actuation of a gas system detector, manual pull station or suppression system pressure switch. Since two detection zones are required as part of a gas system actuation, shutdown of equipment takes place upon detection by either the first or second zone of detection. Refer to Chrysler LLC Fire Protection Standard #103, “Acceptance Test Standards”, for proper system operation and sequence of interlocked shutdown requirements.

17.5 Vehicle Test Room (Dynamometer)

Vehicle test rooms (Dynamometer Rooms) are of several types as follows:

18.0 Fire Protection During Construction

18.1 General

Fires during construction operations are an imminent threat. Fire potential is inherently greater during these operations than in the completed structure due to the presence of large quantities of combustible materials and ignition sources. Arson is also a threat during construction operations due to excessive combustible materials and open access at the construction site.

A construction fire safety program shall encompass the following:

- Housekeeping- On-site Security- Installation of Fire Suppression Systems (as Construction Progresses)- Organization and Training of an On-Site Fire Brigade- Communications- Protection of Special Hazards

18.2 Hazards of Construction

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

Fire retardant tarpaulins or materials of similar fire retardant characteristics (fire retardant treated wood) shall be used for covering the building supplies and temporary enclosure of buildings.

Concrete should be poured as quickly as possible after combustible forms have been constructed. The combustible forms shall be removed as soon as possible after the concrete has set properly.

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

Trash accumulation can present a fire hazard at the construction site. Daily cleanup of debris is required to remove the hazard and provide an orderly-working environment. Trash containers shall be provided on site for proper storage of debris. Combustible trash shall be removed daily.

Cutting, burning, and welding operations provide an ignition source. A Hot Work permit system for cutting, welding and burning operations, as specified by fire protection standards and the insurance carrier, provides controls for safe “hot” work operations.

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

Small quantities of flammable liquids can be safely handled and stored in approved safety containers. Flammable liquids shall be stored in an isolated location. Bulk quantities of flammable or combustible liquids shall not be allowed.

Internal combustion engines shall be placed to avoid exhaust discharge near combustibles. The engine shall be shut down during re-fueling to prevent flash fires. Internal combustion engine driven equipment shall not be used below grade.

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

18.3 Fire Prevention

The Construction Manager shall designate a person to be responsible for the fire prevention program. The fire prevention supervisor shall have the authority to enforce the provisions of applicable fire protection standards.

Standard 105 62

Security service shall be provided at all construction sites. Personnel shall be trained in the following:

Standard 105 65

19.3 Assembly “In” Plant Vehicle Gas Fill Operations

This applies to all Assembly Plants that have inside gasoline fill operations which utilize a containment pit and fuel farm where gasoline is piped to a manual or semi-automatic robotic fill system.

Standard 105 66

Gasoline shall be piped through a preset meter and dispense less than ½ of the vehicle fuel tank capacity (this will prevent an overfilled tank if a vehicle is fueled on the next shift).

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

Provide in the pit an automatic or semi automatic water wash, gaseous agent suppression with rate of rise heat detection and a wet pipe automatic sprinkler system with a separate control valve. Continuous low level ventilation shall be provided. Airflow switches should be monitored. The exhaust ductwork shall also be provided with automatic wet pipe with sprinklers installed maximum on 10 –12 ft. centers.

Interlocks shall be provided such that the ventilation system is de-energized when the gaseous agent suppression system is activated. In addition the main dispensing pumps shall be deactivated.

Provide area signage with “No smoking or open flames” as well as stripping the “red” area zone for 20 ft. minimum in all directions. Signs stating “Only approved cell phones, pagers and radios allowed in area” should be posted in area.

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

Provide portable first aid fire fighting equipment throughout the area.

Do not allow hand talkies, pagers, cell phones etc. in the area unless they are approved by a recognized testing agency for use in hazardous locations.

Provide an emergency fuel tank shutdown button in two remote locations from the gas fill operation. Shutdown button should be interlocked to shutdown conveyor and activate water wash system.

Provide a fusible link valve where the incoming gasoline line penetrates the main building floor or wall and a valve near the fuel pumping equipment.

The gasoline piping from the entry point into the building and the connection point of the fuel dispensers shall be seamless or welded seam whenever it will be over equipment or processes that emit sparks or produces heat. These would include welders, ovens and furnaces. The welding of the piping system must be done by or supervised by a certified welder in pressure piping welding.

All plans for the fuel fill operation or any modifications to the area must be submitted in writing to Corporate Fire Engineer and GRC for review and comment.

19.4 Hydraulic Fluid Systems

Hydraulic Fluid Systems - New Installations:

Use an FM approved less flammable hydraulic fluid where possible.

Before purchasing new hydraulic equipment, the manufacturer of the equipment should be consulted to determine if an FM approved less flammable hydraulic fluid could be used in their equipment. Ensure pumps, seals, gaskets, packing and other system components are checked to ensure they are suitable for the approved less flammable fluid to be used.

Petroleum based hydraulic fluid systems:

1). Emergency shutoff switches should be provided for shutting down hydraulic pumps in the event of a pipe failure or fire. Switches shall be well marked and readily accessible under any anticipated fire conditions.

2). Flexible hose used for connections should be steel reinforced, designed for the hydraulic fluid being used and capable of withstanding four times the maximum working pressure. Hoses should not rub against other objects as a result of machine movement, vibration, or pressure surges.

Standard 105 67

3). Avoid using threaded pipe. However, if used, weld joints using a qualified welder following American Welding Society (AWS) or ANSI/ASME procedures. A safety factor of eight over maximum working pressures should be used.

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

Fire Protection for Petroleum Based Hydraulic Oil Systems:

Sprinkler protection shall be provided over all hydraulic oil equipment unless written permission is obtained from the Chrysler LLC Corporate Fire Prevention Engineer or GRC. NOTE: Normally this will only occur over a single small hydraulic system associated with a detached operation located in a non-combustible structure and located adjacent to non-combustible occupancy (ignition sources normally not present) and the business interruption potential is low i.e., lost production can be readily made up by other existing equipment and damaged equipment can be readily replaced. A provision for prompt manual shutdown of the system must be provided.

Besides automatic sprinkler protection, the additional degree of protection will depend on two issues – 1). The total quantity of petroleum based hydraulic oil that can be released from hydraulic equipment, assuming that the pumps are not shutoff and 2) the normal presence of ignition sources during operating the equipment such as molten metal, heaters, or other hot surfaces above the auto-ignition temperature of the oil being used, open flames or spark producing equipment, such as welding machines.

As a minimum, provide automatic sprinklers over the hydraulic equipment and at least 20 feet beyond in all directions. Also, provide sprinkler protection for all shielded areas, such as pits beneath equipment or platforms.

Sprinkler protection may be dictated by the surrounding occupancy. Based upon Chrysler LLC Standards, minimum sprinkler design shall be 0.30-gpm per sq. ft. over the most remote 4,000 sq. ft. plus 500-gpm hose stream allowance using 286°F sprinklers.

Portable fire extinguishers (Class ‘B-C’) suitable for flammable liquids fires shall be provided. Provide a minimum of a 10# CO2 or Dry Chemical unit for the area

For any petroleum based hydraulic oil system(s) with individual reservoirs/tanks containing more than 100-gallons of petroleum-based hydraulic oil or aggregate 100-gallon within 20-feet of individual tanks, an automatic actuated means for shutting down the oil pump(s) and shutting off the flow from accumulators for hydraulic systems may be required.

If required by the Chrysler LLC Corporate Fire Prevention engineer:

Automatic shutdown of the hydraulic system(s) can be best accomplished by using a thermally actuated fire detection system (such as linear heat detection wire) located directly above the hydraulic operated equipment and at least 20 feet beyond in all directions. Interlock the thermally actuated fire detection system with the emergency stop switch or power supply to the oil pump. The thermal detection device should be rated at least 50ºF above the highest anticipated operating environment temperature.

The use of using a sprinkler water flow switch as a method to automatically shutoff the hydraulic system should be discouraged. Same is true for oil reservoir liquid level switches unless it can be proven to activate the power interlock before 25-gallons or less of hydraulic oil are released.

Large Capacity Systems:

Very large (1,000 gallons or greater capacity) petroleum-base hydraulic oil systems should be located in minimum one-hour rated cutoff rooms protected by automatic sprinklers.

FM Approved Less Hazardous Fluids:

Standard 105 68

FM approved less hazardous fluids are either of the high water base (oil-in-water emulsion), water-in-oil emulsion, water-glycol, or synthetic types. These are referred to internationally as HF-A, HF-B, HF-C and HF-D fluids respectively.

HF-A fluids contain 90% or more water. They are usually used in light-duty applications –pressure below 1,000 psi using special pumps. Recommended temperature limits are 40ºF to 120ºF.

HF-B fluids consist of 35% to 40% water in mineral oil, with a small amount of emulsifying agent, rust inhibitors and anti-wear additives. Recommended temperature limits are 15ºF to 150ºF.

HF-C fluids consist of 35% to 50% water for fire resistance, ethylene or propylene glycol to improve low temperature properties, and additives for proper viscosity and resistance to corrosion, wear and bacteria. Recommended temperature limits are 0ºF to 150ºF with normal operations at 120ºF to 150ºF.

Most synthetic fluids (HF-D fluids) are one of four types: phosphate esters, chlorinated hydrocarbons, blends of phosphate esters and chlorinated hydrocarbons, and fluids containing other compositions. Recommended temperature limits are 20ºF to 200ºF.

Synthetic fluids are not compatible with natural rubber, Buna, or neoprene seals or hoses. Synthetic fluids also may attack metal protective paints, lacquers and electrical wiring insulation.

19.5 Platforms

Platforms (solid and/or grated flooring):

Platforms that are 36-inches or higher above finished floor and wider than 48 inches shall be protected by one of the following methods:

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

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).
