PORTABLE FIRE EXTINGUISHERS


APPROVAL CATEGORY: 162.028

APPROVAL GUIDANCE & INFORMATION:  The Coast Guard does not conduct approval review of Portable Fire Extinguishers.  The regulations require that extinguishers are tested, and listed and labeled by a Coast Guard recognized Independent Testing Laboratory.  The Listing includes testing, and follow-up inspections by the recognized Independent Testing Laboratory at the manufacturer’s production facilities.  Currently, Underwriters Laboratories, Inc. (UL) and Underwriters Laboratories of Canada (ULC) are Recognized Independent Laboratories.  Essentially, the recognized Independent Testing Laboratories administer the Coast Guard’s extinguisher approval program on the Coast Guard’s behalf with Coast Guard oversight.

The USCG marking requirements for marine extinguishers differs from NFPA/UL markings.  The USCG rates extinguishers primarily on net agent weight rather than on fire test size as determined by ANSI/UL711.  Extinguishers with agent weights below those referenced in the vessels regulations and which do not have a minimum 5-B:C fire test rating per ANSI/UL711 are considered too small for marine use and are not approvable.

The Coast Guard does not issue certificates of approval for portable fire extinguishers.  Instead, an approved extinguisher are can be identified by the marine type label, such as “Marine Type, USCG approved, Type X. Size X, USCG approval number 162.028/XX.”  The XX signifies the laboratory’s identification number for the particular extinguisher.  USCG approved extinguishers are listed in the laboratory’s equipment directories and web sites.

The extinguishers are tested for compliance with the applicable ANSI/UL standards.  Specifically, extinguishers are expected to comply with the following:

* The Coast Guard currently requires additional corrosion tests for unpainted stainless steel extinguisher shells because of prior corrosion problems such shells experienced in a marine environment. This has limited the number of approved water and foam extinguishers.

The maintenance of extinguishers must be in accordance with NFPA#10, as stated on each extinguisher label.

SUBMITTAL PACKAGE:  Application should be made directly to the Accepted Independent Testing Laboratory.

FIXED FIRE EXTINGUISHING SYSTEM (Pre-Engineered)


APPROVAL CATEGORY:  162.029

APPROVAL GUIDANCE & INFORMATION:  U.S. Coast Guard regulations require the installation of U.S. Coast Guard approved fixed gaseous extinguishing systems on certain U.S. registered inspected vessels and permit the substitution of an approved system for one of the required approved portable fire extinguisher on pleasure craft.

In order to obtain a certificate of approval (i.e. type approval), compliance with the following criteria is required.  These criteria determine the equivalency of new clean agent systems to the carbon dioxide systems currently specified in the various vessel regulations, and to the halon systems previously approved as equivalent to carbon dioxide systems.  This updates and supplements the test program outlined in our Notice of Proposed Rulemaking published in the Federal Register on Wednesday, January 9, 1991, pages 829 through 836, to enable inclusion of clean agent replacements for halons.

1)    Approvals are issued only for complete systems made up of specific components and utilizing specific extinguishing agents.  Approval is not issued for individual system components, such as individual hardware or extinguishing agents.  The Coast Guard does not test materials or systems for approval but rather specifies the required test methods and minimum performance criteria for approval.  Product testing must be performed by a Coast Guard Accepted Independent Laboratory.

2)    The extinguishing agent must be acceptable to the U.S. Environmental Protection Agency (EPA) under the Significant New Alternatives Policy (SNAP list) without restrictions that limit its use in marine applications.

3)    The agent must be recognized as a fire extinguishing medium by NFPA Standard #2001 on Clean Agent Fire Extinguishing Systems.

4)    Systems must be listed and labeled for marine use by an independent testing laboratory accepted by the Coast Guard under 46 CFR 159.010.  Laboratories currently so accepted are FM and UL.  All tests must be conducted under the control of the laboratory.  To be acceptable, the laboratory must apply and be accepted in accordance with 46CFR 159.010 prior to conducting any tests.  A laboratory must demonstrate independence and technical expertise in the evaluation of the fire suppression systems in accordance with the latter regulation.

5)    Systems must be intended for installation in spaces that are normally unoccupied, and that personnel can leave within 10 seconds after the system is actuated.

6)    Systems are approved based on fire tests in simulated compartments of pre-determined size, and are not designed individually for each engine compartment.

7)    The primary system actuator must be automatic if the agent cylinder is installed in the protected space.

8)    Systems must have discharge indicators for installation at each helmsman’s position.

9)    System components must meet UL 2166 “Standard for Halocarbon clean agent Extinguishing System Units.”

10)   System must be intended for the protection against Class B hazards (flammable liquids) in machinery and bilge spaces, and Class C hazards (non-shock hazard when applied to energized electrical equipment).

11)   Systems intended for installation in small passenger vessel (46 CFR Subchapters T and K) must have manual (mechanical) back-up actuators, audible alarms, and automatic engine and ventilation shutdown upon system discharge.  The engine shutdown feature must have a mechanism to quickly restart the engine(s).

12)   Systems using fusible elements for actuation are limited to installation in spaces not exceeding 2000 cubic feet.  Systems for larger unoccupied spaces or any spaces intended for human occupancy must be specifically designed for each space protected, i. e. engineered, and must provide personnel safeguards such as limits on the agent concentration, discharge delays, and pre-discharge alarms.

13)   Systems for fishing industry vessels are limited to spaces not exceeding a volume of 1200 cubic feet.

14)   The volume of the compartment protected must be the gross volume: the length times the width times the depth of the compartment.  The volume of installed equipment such as engine blocks and fuel tanks may not be deducted, unless the boat manufacturer provides a factory installed placard that states the volume of the installed tanks and engine blocks.

15)   Systems must be self-contained, i.e. not require an external source of power such as the boat’s electrical system for activation.

16)   Systems must be intended for installation in engine compartments where natural ventilation does not exceed one air change per minute.  If mechanical ventilation is provided or if the natural ventilation is expected to be greater, a system tested under the higher air flow conditions must be installed.

17)   Systems containing a charge of nitrogen in addition to the extinguishing agent must have a listed pressure gage.  This gage is not a substitute for the required discharge indicator.

18)   Systems intended for installation in volumes of 1000 cubic feet and larger must have a manual back-up actuator.

19)   The system must be tested by the independent lab as follows:

a.    Discharge tests per section 23 of UL2166.

b.    Valve leakage tests per section 24 of UL2166.

c.    Hydrostatic tests per section 25 of UL2166.

o.    Marine tests per Supplement SA of UL 2166, including salt-spray corrosion, vibration                resistance, and shock resistance tests.

20)   Fire tests must be conducted in accordance with UL 2166.  For systems without piping the fire tests of section 36 of UL 2166 must be conducted.  The test must be repeated at the system manufacturer’s design concentration and under conditions of one air change per minute for the test enclosure.

21)   For the latter the test compartment must be ventilated at one air change per minute.  Systems not incorporating an automatic engine shutdown feature must have placards for attaching to each helmsman’s position stating that the engine(s), generator, and any powered ventilation must be manually shutdown upon system activation.

22)   Each system must have an owner’s instruction manual containing installation and maintenance instructions.  Systems for pleasure craft are generally intended to be installed by the boat owner.  Systems for inspected vessels are more complex since they require engine shutdowns, and are to be installed by system distributors or marine electricians.  The owners manual must be specific to marine applications and must include the following:

a.  Maximum gross volume limitations and maximum engine room/bilge dimensions.

b.  Storage temperature range.

c.  Coast Guard approval number.

FOAM TYPE FIRE EXTINGUISHING SYSTEM


APPROVAL CATEGORY:  162.033

APPROVAL GUIDANCE & INFORMATION:

Subchapter D of Title 46 of the Code of Federal Regulations (CFR) requires the installation of fixed low expansion foam fire extinguishing systems on decks of tankers for the protection of all cargo tanks.  These systems are intended to provide protection against flammable liquid fires in the cargo area.  An explanation of the basic characteristics of marine foam systems is contained in USCG Navigation and Vessel Inspection Circular (NVIC) No. 6-72.  These systems must be designed to:

1.      Extinguish the fire:  Each foam formulation (type, percentage, etc.) must successfully extinguish a series of test fires using fuels representative of the type of cargoes carried on the vessels for which the systems are intended, as for example, gasoline as a test fuel for hydrocarbon cargoes.  Tests will include foam generated with fresh and synthetic sea water.

2.      Prevent re-ignition of the fuel for a period of time:  Each foam must demonstrate its ability to prevent ignition sources above the foam blanket from igniting the fuel below the foam blanket.  In addition, the foams must prevent fire of small areas of exposed to fuel from increasing in size.

3.      Resist foam breakdown and provide a seal against hot metal:  As part of the above, each foam must demonstrate its ability to form an effective blanket, and to resist foam breakdown due to contact with hot metal.

Approval is granted only for complete systems.  Foam concentrates and individual components such as nozzles and monitors are not type approved individually; however, combinations of such components complying with UL 162 may be used to meet requirements for SOLAS "portable foam applicators" (see: Marine Inspection Notice).

Fire tests of foam concentrate

Foam concentrates are subjected to marine fire extinguishment and burn back tests in accordance with the National Fire Protection Association Standard No. 11, Annex G.  This test method was derived from Fed. Spec. O-F-555C, and is designed to evaluate the fire extinguishing capability of the foam concentrate when applied with a standard nozzle in a manner representative of ship-board applications.

Foam quality tests using the standard nozzle are conducted during this test series, and the foam quality obtained during this test series is compared to the foam quality obtained from the systems manufacturer’s hand line nozzles and turret monitors.

The fire tests must be conducted either at UL’s indoor facilities, or other facilities acceptable to the USCG.

A safety factor of 8/3 times the foam applications rate during the fire test will be applied to establish the minimum design foam application rate.

System component tests in accordance with UL 162

System components must demonstrate satisfactory performance when tested for compliance with Underwriters Laboratories, Inc. (UL) Standard No. 162.  These tests include proportioning, foam quality, hydrostatic strength, leakage, friction loss, and exposure of components to the liquid concentrate.  The foam quality must compare to the foam quality obtained during the above fire test within the tolerances specified by UL 162.

Polar solvents

Polar solvent foam systems are water miscible products such as alcohols and ketones which attack regular fire fighting foams.  Special polar solvent or alcohol resistant foams have therefore been developed where the foam application rate varies with the particular polar solvent cargo.  Polar solvent cargoes may be protected with a uniform high SOLAS polar solvent foam application rate, or with specific lower application rates for specific polar solvent groups based on fire tests of representative cargoes.  NVIC 11-82 provides details.

Foam concentrates intended for the protection of polar solvent cargoes must be tested (in addition to being effective on hydrocarbon fuels) using several selected polar solvent fuels which are representative of specific classes of fuels (such as esters, ketones, acids, etc.).  These tests are conducted in accordance with the relevant sections of UL 162, and will establish the foam application rate necessary for each category of polar solvents.

UL Listing

The foam concentrate must be UL listed.

UL Listing of marine foam systems as a whole is preferred but has not been enforced.  However, foam system components submitted are usually already UL Listed for industrial applications.  UL Listing reports for various foam system components are therefore given consideration in lieu of new tests.

Any non-collapsible (hard rubber) hose must either be UL Listed or be of comparable construction.

Component tests in addition to UL 162

Foam discharge range tests using monitor turrets must be conducted to determine the effective range of foam discharge.  The design range of the monitors as reflected in the system Manual is limited to 75% of the tested still air range.

The compatibility of any metallic or nonmetallic tank material with the various foam concentrates must be established.

ASME pressure tanks must meet the criteria of Subchapter F of Title 46 of the CFR.

Piping sections carrying AFFF concentrate (not foam solutions) must be made of stainless steel.

The Coast Guard does not test materials or systems for approval but rather specifies the required test methods and minimum performance criteria for approval.  Product testing must be performed by a Coast Guard Accepted Independent Laboratory.

SUBMITTAL PACKAGE:  Please submit the follow information in the Submittal Package:

1.      The system manufacturer must provide a draft Marine Design Installation, Operation, and Maintenance Manual.  USCG testing is intended to spot-check the hydraulic data contained in the Manual, not to conduct basic data development.

2.      Description of system design, including system schematic

3.      A complete list of components (hardware)

4.      Drawings of major system components, such as nozzles, monitor turrets, proportioners, etc.

5.      Hydraulic data for system components (friction loss through components, pipe friction loss tables, etc.)

6.      List of types and characteristics of foam concentrates (protein or AFFF, percent concentration, trade names of concentrates, etc.), as well as instructions and acceptance criteria for periodic sampling of foam concentrates obtained from each ship.

7.      Test data, such as proportioning curves, discharge curves (flow vs. supply pressure), ranges of foam discharge from nozzles, which will permit the establishment of a detailed test program to verify the manufacturer’s performance data.

8.      Sample calculations and drawings for typical foam system installations in accordance with the applicable vessel regulations (such as 46 CFR 34.17 for tank vessels) which will enable USCG personnel to verify calculations for each system installed on a specific vessel.  The drawings must show the location of the deck foam monitors and the range of the foam stream from the monitors which may not exceed 75 % of their tested still air range.

9.      Required system testing and maintenance instructions.

10.    For polar solvent foam systems, a set of Annexes which contain the design foam application rate for each chemical cargo the systems is intended to protect.

HALON 1301 TYPE FIRE EXTINGUISHING SYSTEM


APPROVAL CATEGORY:  162.035

APPROVAL GUIDANCE & INFORMATION:  The production of Halon 1301 fire fighting agent was terminated effective January 1, 1994, and the installation of new halon systems on SOLAS ships prohibited.  However, existing systems may be retained if in good and serviceable condition.

CARBON DIOXIDE TYPE FIRE EXTINGUISHING SYSTEM


APPROVAL CATEGORY:  162.038

APPROVAL GUIDANCE & INFORMATION: Type approved systems must be listed and labeled for marine use by a Coast Guard accepted independent testing laboratory. The laboratory uses the criteria in NFPA 12 and the vessel regulations, along with appropriate environmental tests for major system components as a basis for the listing.

Fire extinguishing tests and nozzle distribution tests not required as part of the approval testing, since the carbon dioxide used in fire protection systems is a standard commercial grade product with known, uniform fire extinguishing properties.

Carbon dioxide is a very effective fire extinguishing agent; however, the concentration of carbon dioxide needed for fire extinguishment can cause injury or death during and after discharge. Navigation and Vessel Inspection Circular 9-00, Change 1, Carbon Dioxide System Safety, provides detailed safety information on the risks of carbon dioxide systems, and should be consulted to fully understand the safety precautions to be taken whenever testing or inspecting carbon dioxide systems.

The regulations provide a number of comprehensive safety measures to safeguard personnel from these risks, including requirements for:

  1. Conspicuous warning signs to be posted by the entrances to carbon dioxide cylinder rooms, any spaces protected by carbon dioxide systems, and any adjacent spaces where carbon dioxide could migrate;
  2. Evacuation of all normally occupies spaces before the extinguishing agent is discharged;
  3. Pre-discharge warning sirens in the protested space that sound for a sufficient period of time to allow the crew to evacuate the space before the discharge begins; and
  4. System releasing stations designed to require the operation of two separate and distinct controls before system discharge is initiated, to prevent a single action from accidentally releasing the system.
In addition, all systems installed or materially altered after July 9, 2013 will be required to have manually operated lockout valves and odorizing units in the system discharge piping to allow the protected space to be completely isolated from the carbon dioxide supply whenever the system is being serviced or tested, and add wintergreen odor to the gas during discharge to allow personnel to quickly recognize any areas where carbon dioxide may be present.

SEMI PORTABLE MARINE TYPE FIRE EXTINGUISHER


APPROVAL CATEGORY: 162.039

APPROVAL GUIDANCE & INFORMATION:  The Coast Guard defines semi-portable extinguishers as those fully charged extinguishers weighing more than 55 pounds.  Semi-portable extinguishers must be self-contained, i.e. not rely on additional sources of agent or expellant energy.  They may be wheeled or skid-mounted.

The regulations require that extinguishers are tested, listed and labeled by an Independent Testing Laboratory recognized by the Coast Guard.  The Listing includes testing, and follow-up inspections by the recognized Independent Testing Laboratory at the manufacturer’s production facilities.  Currently, Underwriters Laboratories, Inc. (UL) and Underwriters Laboratories of Canada (ULC) are  recognized Independent Laboratory.  Essentially, the recognized Independent Testing Laboratories administer the Coast Guard’s extinguisher approval program on the Coast Guard’s behalf with Coast Guard oversight.

The extinguishers are tested for compliance with the applicable ANSI/UL standards.  Specifically, extinguishers are expected to comply with the following:

* The Coast Guard currently requires additional corrosion tests for stainless steel extinguisher shells because of prior corrosion problems such shells experienced in a marine environment. This has limited the number of approved water and foam extinguishers.

The maintenance of extinguishers must be in accordance with NFPA#10, as stated on each extinguisher label.

The USCG marking requirement for marine extinguishers differs from NFPA/UL markings.  The USCG rates extinguishers primarily on net agent weight rather than on fire test size as determined by ANSI/UL711.  Extinguishers with agent weights below those referenced in the vessels regulations and which do not have a minimum 5-B:C fire test rating per ANSI/UL711 are considered too small for marine use and are not approvable.

The Coast Guard does not issue certificate of approval for portable and semi-portable fire extinguishers.  Instead, approved extinguishers are can be identified by the marine type label, such as “Marine Type, USCG approved, Type X. Size X, USCG approval number 162.039/XX.”  The XX signifies the laboratory’s identification number for the particular extinguisher.  USCG approved extinguishers are listed in the laboratory’s equipment directories and web sites.

SUBMITTAL PACKAGE:  Application should be made directly to the independent testing laboratory.
