![]() ![]() This test determines the ability of a streamingĪgent to function as a flooding agent. The hidden fire test evaluates the flooding characteristics of the agentĪgainst a hidden in-flight fire. Halon replacement agents found to be compliant to date include the halocarbons The MPS specifies two extinguisher tests that replacement agents must pass:Ī hidden fire and a gasoline-drenched seat fire. Onboard fires and decomposition product toxicity the passengers and crew. ![]() The purpose of the MPS is to ensure that extinguishers using halon replacementĪgents pose no reduction in safety, both in terms of effectiveness in fighting Minimum Performance Standard for Hand-Held Extinguishers Moreover, the full-scale fire tests can be used to deriveĬertification criteria to allow for the approval of new agents/extinguishers/systems That a replacement agent is equivalent to halon in terms of fire extinguishment/suppressionĮffectiveness. The main purpose of each MPSs is to define full-scale fire tests to demonstrate Halon Replacement Working Group (now called the International Aircraft Systemsįire Protection Working Group) to develop MPSs for each of the four aircraftĪpplications: lavatories, hand-held extinguishers, engines/auxiliary power ![]() ![]() Ozone Layer, the production of halons ceased in developed countries on Januaryġ, 1994, although the use of halons was not prohibited for aviation uses.Īt that time the FAA convened an informal working group, the International With the signing of the Montreal Protocol on Substances that Deplete the Types of halons are employed in aviation: Halon 1301, CBrF 3,Ī total flooding agent and Halon 1211, CBrClF 2, a streaming agent. Is electrically nonconducting, and has relatively low toxicity. Range of aircraft environmental conditions, is a clean agent (no residue), Halon has been the fire-extinguishing agent of choice in civil aviationīecause it is extremely effective on a per unit weight basis over a wide Is equivalent to halon in fire-extinguishing effectiveness. Standards (MPS) that describe the full-scale fire tests, which the FAA willĪccept to demonstrate that an environmentally acceptable replacement agent Under FederalĪviation Administration (FAA) sponsorship, the International Aircraft Systemsįire Protection Working Group (IASFPWG) has developed Minimum Performance Although halon usage has beenīanned in some parts of the world, aviation has been granted an exemptionīecause of its unique operational and fire safety requirements. Has been banned by international agreement. Halon is an ozone depleting and global warming chemical and its production The only fire extinguishing agents used in civil transport aircraft. capacity are not approved.20-42D - Hand Fire Extinguishers for Use in Aircraftįor over 45 years, halogenated hydrocarbons (halons) have been practically Halon 1211 fire extinguishers exceeding 20 lb. Coast Guard regulations do not allow the use of hand portable stainless steel fire extinguishers therefore Stored Pressure Water, AFFF and FFFP Foam are not approved. U/L requires that the model or part number of the bracket in which the extinguisher was tested for its marine listing be noted on the extinguisher nameplate (label). A Marine Bracket must be used when mounting a fire extinguisher for marine use. All extinguishers must be “restrained” in mounting brackets of the marine or motor vehicle type which have been subjected to the same rigid salt spray and vibration tests as the extinguishers (wall type brackets are not acceptable). of CO2 are necessary to meet the requirements for a Coast Guard B classification. It is recommended the extinguishers be mounted in a readily accessible position.Īll “marine type” extinguishers must have the Coast Guard classification system marking and approval number on the label. Obtain a copy of "Federal Requirements for Recreational Boats" for more information on how many and what types of equipment you must carry on your boat.Ĭoast Guard Approved extinguishers are hand-portable, either B-I or B-II classification and have a specific marine type mounting bracket. Boats carrying passengers for hire may have additional equipment requirements. (Consider additional units for extra safety precaution). Please note that these figures are the absolute minimum. These charts show the United States Coast Guard minimum equipment requirements for fire extinguishers on boats. ![]()
