This AC provides reference information on these aircraft fire fighting extinguishing agents and their allowable use: 1. Primary agents Complementary agents 3. Other agents Each fire extinguishing agent has advantages, limitations, equipment requirements, and unique application techniques. Airports should confirm the shelf life of all extinguishing agents in use at their airports 1.2 1.2.1 1.2.2 Primary Agents. A primary agent is designed for mass application and rapid fire knockdown. Foams are used for control and extinguishment of aircraft fires involving fuel spills and are produced by incorporation of air into a solution of foam concentrate and water. Their characteristics, as indicated by expansion and drainage rate, are influenced by the amount of mechanical agitation to which the water, foam concentrate, and air are subjected. They extinguish fire by physically separating the fuel vapors from the heat and oxygen necessary for combustion, spreading over the surface of the fuel to effectively suppress vaporization and secure an extinguished area by protecting it from reignition. Foam, being essentially water, cools the surface of the fuel and any metal surfaces in the fire. It is advantageous for a foam blanket to reseal if disrupted, and essential that either the foam has good thermal and mechanical stability or that provision is made by renewing the foam blanket from time to time. Aqueous Film Forming Foam (AFFE). Aqueous Film Forming Foam (AFFF) acts as a barrier both to exclude air or oxygen and to develop an aqueous film on the fuel surface that is capable of suppressing the evolution of fuel vapors. The foam produced with AFFF concentrate is dry chemical compatible. Qualified AFFF products are available in 3% and 6% concentrates and mixed with 97% and 94% water by volume, respectively, to create a foam solution upon discharge. The solution drainage forms an aqueous film on most aviation fuels. Fluorine-Free Foam (F3). Fluorine-Free Foam (F3), also known as Synthetic Fluorine Free Foam (SFFF), will be known and referred to by the FAA and the Department of Defense (DoD) as only F3 from this point forward. F3 is a foam concentrate based on a mixture of hydrocarbon surface active agents that are fluorine free. The foam produced with F3 concentrate that are certified to MIL-PRF- 32725, Fire Extinguishing Agent, Fluorine-Free Foam (F3) Liquid Concentrate, for Land- Based, Fresh Water Applications, and listed on the Qualified Products Database (QPD) is 1-1 71901843281 11/27/2023 AC 150/5210-6E dry chemical compatible. Qualified F3 products are only currently available in 3% and mixed with 97% water to create a foam solution upon discharge. Due to the absence of fluorosurfactants, F3s are not capable of forming a film to suppress fuel vapors. As a results, f'3s suppress fires in only two ways: cooling the fuel with the water component and suppressing the fuel vapors with the foam blanket. Since F3s rely on the foam blanket for vapor suppression, blanket structure and maintenance is critical to maintaining protection. Exposed fuel and areas with minimal blanket coverage will continue to be vapor sources until the blanket has been restored or the fuel is removed. Additionally, F3 foam blankets do not spread like AFFF, meaning disruptions to the foam blanket must be addressed by applying additional foam to the area to maintain vapor suppression. Safety Notice No. 1 Fluorine-Free Foam (F3) F3 concentrates are not compatible with other F3 and AFFF concentrates and should never be mixed together in vehicles or storage tanks 1.3 1.3.1 Complementary Agents. A complementary agent is an extinguishing agent that has the capability to perform fire- suppression functions when used alone or in support of a primary extinguishing agent and where extinguishment might not be achievable using only the primary agent. Clean Agents. A clean agent is an electrically nonconducting volatile liquid or gaseous fire extinguishing agent that does not leave a residue upon evaporation and has been shown to provide extinguishing action. Some clean agents are effective on Class A, B and C fires. 1.3.1.1 Halogenated Extinguishing Agents. Halogenated extinguishing agents are hydrocarbons in which one or more hydrogen atoms) have been replaced by one or more atom(s) from the halogen series — commonly fluorine, chlorine, bromine, or iodine. This substitution confers not only nonflammability but flame extinguishment properties to many of the resulting compounds. Halogenated agents are used both in portable fire extinguishers and in extinguishing systems. Halotron I is a complementary, halogenated extinguishing agent that is approved as an alternative fire fighting agent to Halon 1211 for airport fire fighting use. Extinguishing mechanisms vary for halogenated extinguishing agents. The primary extinguishing mechanism for Halon 1211 acts by chemically interrupting the continuing combination of the fuel radicals with oxygen in the flame chain reactions. This process is known as "chain breaking." Some halogenated agents act by increasing the heat capacity of 1-2 11/27/2023 AC 150/5210-6E 1.3.2 the air within the fire zone. This results in a cooling of the fire by removing the heat the reaction needs to sustain the flame. Safety Notice No. 2 Halogenated Agents Halogenated agents will produce acidic gases when discharged onto a fire. Dry Chemical Agents. Dry chemical agents include either sodium or potassium based powders intended to extinguish liquid fuel fires. The U.S. airport fire fighting industry relies almost exclusively on the use of potassium-based chemicals as auxiliary extinguishing agents due to their compatibility with AFFF agents and their reliable fire performance. Dry chemicals are the most common complementary agent used; however, they are abrasive corrosive, and leave a residue. 1.3.2.1 Sodium Bicarbonate-Based Dry Chemical. This agent consists primarily of sodium bicarbonate (NaHCO3) and is suitable for use on all types of flammable liquid and gas fires (Class B), and for fires involving energized electrical equipment (Class C). It Is particularly effective on fires in common cooking oils and fats. In combination with these materials, the sodium bicarbonate-based agent reacts to form a type of soap (saponification) that floats on a liquid surface and effectively prevents re-ignition of the grease. Sodium bicarbonate-based dry chemical is not generally recommended for the extinguishment of fires in ordinary combustibles (Class A), although it can have a transitory effect in extinguishing surface flaming of such materials. 1.3.22 Potassium-based Dry Chemical. Commercially available agents are essentially potassium bicarbonate (KHCO3), potassium chloride (KCI), and urea-based potassium bicarbonate (KCzN½H;O3). All three agents are suitable for use on all types of flammable liquid and gas fires (Class B) and also for fires involving energized electrical equipment (Class C). It is gencrally recognized that salts of potassium are more effective in terms of chemical extinguishment mechanisms than sodium salts in extinguishing Class B fires, except those in deep-fat fryers and other cooking equipment. Dry chemicals based on the salts of potassium are not generally recommended for the extinguishment of fires in ordinary combustibles (Class A), although they can have a transitory effect in extinguishing surface flaming of such materials. 1-3 ELSE ELL BRILL: 2E.: 11/27/2023 AC 150/5210-6E 1.4 1.4.1 1.4.2 Other Agents. These agents are typically carried in a handheld extinguisher for a specific application specified by either UL or National Fire Protection Association (NFPA) certification. Combustible Metal Agents. Agents used to combat Class D fires, such as magnesium fires, are referred to as combustible metal agents. Heat from the fire causes the powder to form an air- xcluding crust. Powders do not cling well to vertical surfaces. Two agents currentl pproved for use are Metal-X as a dry powder agent and FEM-12 as either a liquid or dry powder agent. Carbon Dioxide. Carbon dioxide (CO2) is colorless, electrically nonconductive inert gas that is a suitable medium for extinguishing Class B and Class C fires. Carbon Dioxide gas is 1 ½ times heavier than air. Carbon Dioxide extinguishes fire by reducing the concentration of oxygen, the vapor phase of the fuel, or both in the air to a point where combustion stops. NFPA 10, Standard for Portable Fire Extinguishers (National Fire Protection Association 2022), $ 3.3.3. 1.4.3 Safety Notice No. 3 Carbon Dioxide In high concentrations, CO2 can cause unconsciousness and death. Water Additives. An agent that, when added to water in proper quantities, suppresses, cools, mitigates fire and/or vapors, and/or provides insulating properties for fuels exposed to radiant heat or direct flame impingement. Water additives can materially reduce water's surface tension and increase its penetrating and spreading abilities; they also might provide enhanced cooling, emulsification, and foaming characteristics. The two most common water additives are wetting agents and encapsulator agents. Wetting agents reduce the surface tension and increase the water's ability to penetrate and spread. Emulsification and foaming characteristics may be enhanced. Encapsulator agents change the chemical make-up of a water droplet with the introduction of spherical micelles to neutralize the fuel. For further information, refer to NFPA 18, Standard on Wetting Agents (National Fire Protection Association 2021), and NFPA 18A, Standard on Water Additives for Fire Control and Vapor Mitigation (National Fire Protection Association 2022). 1-4 11/27/2023 AC 150/5210-6E CHAPTER 2. AIRPORT INDEXES, AGENT CAPACITIES, AND CRITICAL AREAS 2.1 22 2.3 2.3.1 2.3.2 Airport Indexes. Use §139.315 to determine the ARFF Index (A through E) for airports serving Department of Transportation (DOT) certificated air carriers/commercial service. Use $139.317 to determine the rescue and fire fighting equipment and agents that are the minimum required for the indexes referred to in §139.315. Agent Capacities. ARFF vehicles are required to come from the manufacturer meeting the regulatory requirements for agent capacity found in $139.317. The FAA recommends airports maintain an equivalent of a 200% resupply for foam and a 100% resupply for complementary agent and propellant. Critical Area. The critical area is an area to be protected in any post-accident/incident situation that permits the safe evacuation of the aircraft occupants. The critical area serves as a basis for calculating quantities of an extinguishing agent necessary to achieve protection in an acceptable time period. Theoretical Critical Fire Area (TCA). The TCA serves as a means of categorizing aircraft in terms of the magnitude of the potential fire hazard in which they may become involved. It is not intended to represent the average, maximum, or minimum spill fire size associated with a particular aircraft. See Appendix A for further background information related to TCA. Practical Critical Fire Area (PCA). The PCA is two-thirds the size of the TCA for fixed wing aircraft. The PCA and the related quantities of extinguishing agents are based on criteria formulated during the Second Meeting of the International Civil Aviation Organization (ICAO) Rescue and Fire Fighting Panel (RFFP II) in June 1972. RFFP II developed material indicating the practical area is two-thirds of the theoretical area based on the Panel's work, which included a study of extinguishing agents used on actual aircraft fires. In 99 out of 106 studied fires, the quantities of agents used were less than those previously recommended by ICAO. See Appendix A for further background information related to PCA 2-1 HERE EL SEDILE! = 11/27/2023 AC 150/5210-6E Figure 2-1. TCA and PCA for Aircraft -- Theoretical critical fire area (TCA) Practical critical fire area (PCA) : A Wind direction Fixed-wing aircraft Note: The TCA is a rectangle shape having as one dimension the overall length of the aircraft, and the second dimension determined by the following: a. For aircraft with an overall length of less than 65 ft (20 m): 40 ft (12 m) plus the width of the fuselage. b. For aircraft with an overall length of 65 ft (20 m) or more: 100 ft (30 m) plus the width of the fuselage. 2.4 2.5 Control Time. The control time is the time required from the arrival of the first fire fighting vehicle nd the beginning of agent discharge to reduce the initial intensity of the fire by 90%. 1 s essential that equipment and techniques control the fire in the PCA in one minute NFPA 460, Standard for Aircraft Rescue and Firefighting Services at Airports (National Fire Protection Association 2024), Annex B, §B.3. Extinguishment Time. Extinguishment time is the time required from arrival of the first fire fighting vehicle to the time the fire is completely extinguished. NFPA 460, Annex B, $B.3. 2-2 11/27/2023 AC 150/5210-6E CHAPTER 3. AGENT COMPATIBILITY, SUBSTITUTIONS, AND PERFORMANCE REQUIREMENTS 3.1 Agent Compatibility. Chemical compatibility is a measure of how stable one substance is when mixed with another substance. Two substances are considered to be incompatible when, it mixed 3.2 3.3 3.3.1 Extinguishing Agent Substitutions. Other extinguishing agent substitutions authorized by the Administrator may be made in amounts that provide an equivalent fire fighting capability. Extinguishing agent substitutes are discussed in §139.317(h). The following are authorized substitutions: 1. 450 Ibs of potassium-based dry chemical is an allowable substitution for 500 pounds of sodium-based dry chemical §139.317 (b) (c) (d) (e). F3 qualified under Military Performance Specification (MIL-PRF)-32725, Fire Extinguishing Agent, Fluorine-Free Foam (F3) Liquid Concentrate, for Land- Based, Fresh Water Applications, and listed on the Qualified Products Database (QPD) is an allowable substitution for AFFF in equal quantities as identified in §139.317. 3. 460 Ibs of Halotron is a qualified clean agent substitution for 500 lbs of Halon 1211, as identified in §139.317. Performance Requirements. AFFF agents are to meet the requirements of MIL-PRF-2438SF. This military specification ensures cross-compatibility of the AFFF products regardless of manufacturer. F3 agents are required to meet the standards set forth in MII-PRF-32725. F3 fire fighting foam concentrates are not cross-compatible between foam manufacturers. Actions. Airport operators are to confirm: 1. The AFFF or F3 mects the standards and it appears on the Qualified Products List (QPL) found on the QPD website. If the AFFF or F3 is not on the QPL, the product does not meet the performance requirements of MIL-PRF-24385F or MIL-PRF-32725. 3-1 11/27/2023 3.3.2 AC 150/5210-6E Quality Product List (QPL) Website. 1. Since the QPL is updated periodically, the FAA recommends airports check and review the QPL for any updates or changes. 2. For qualified AFFF products, refer to the QPD at https://apldocs.dla.mil/ and search for "AFFF" searching by title. For qualified F3 products, refer to the QPD at https://apldocs.dla.mil/ and search for "F3" searching by title. 3-2 11/27/2023 AC 150/5210-6E CHAPTER 4.

Airports should consider establishing local Standard Operating Guidelines/Standard perating Procedures (in conjunction with local or state environmental regulator ganizations) to identify a suitable location/storage container to discharge AFFF or F for testing to ensure the functionality of the foam proportioning system on each ARFF vehicle. Airports should establish safe and environmentally effective handling and disposal procedures during testing and re-servicing of each ARFF vehicle with all fire extinguishing agents in accordance with local and state, and federal regulations. The FAA has allowed airports to use the input based testing system to test the foam proportioning system on their ARFF vehicles. Note: NFPA 460, Standard for Aircraft Rescue and Firefighting Services at Airports (National Fire Protection Association 2024), Chapter 29, addresses foam concentration tolerances for ARFF Vehicles. Airports should consider using one of the following input based testing systems, accepted by the FAA for immediate use, to satisfy the Part 139 testing requirement while minimizing any possible environmental impact: 1. E-One - Eco-Logic System 2. NoFoam System 3. Oshkosh - Eco Electronic Foam Proportioning (Eco-EFP) System 4. Rosenbauer - FixMix 2.0E Electronic Foam Proportioning System Note: Input-based tests done by the FAA had a greater correlation to output-based tests at a 3% proportioning rate than at a 6% proportioning rate. Confirmation testing performed by the vendor at delivery/installation that compares input- and output-based tests may help offset this difference by establishing reference values representing the current state of the vehicle. Therefore, the FAA highly recommends airports have the vendor perform this confirmation testing at the time of delivery. Note: The FAA recommends vehicle system testing occurs within the six-month period before the airport's periodic airport certification safety inspection. Note: ARFF vehicle foam proportioning systems should be tested in accordance with NFPA 460. 4-1 11/27/2023 AC 150/5210-6E Page Intentionally Blank 4-2 11/27/2023 AC 150/5210-6E Appendix A APPENDIX A. SUPPLEMENTAL INFORMATION A.1 A.2 Halotron I. Subsequent to the U.S. decision to halt production of halon as part of the Montreal Protocol (reference NFPA 460, Annex A, §A.5.2 (2)) and the use of halon-based agents (e.g., Halon 1211) in live fire, training stopped because of its environmental effects. Halotron I has completed the scale fire test performance evaluations protocols of FAA Technical Report DOT/FAA/AR-95/87, Full Scale Evaluations of Halon 1211 Replacement Agents for Airport Fire Fighting, as stated in the Part 139 definition of a clean agent. The FAA teamed with other agencies and industry and identified an acceptable alternative to using halon-based agents in airport rescue fire fighting vehicles. Several potential agents were evaluated. Only the Halotron I product has completed scale fire test performance evaluation and was approved as an alternative fire fighting agent to Halon 1211 for airport fire fighting use. Halotron I has additionally been deemed to be an environmentally acceptable replacement for Halon 1211 by the Environmental Protection Agency (EPA). Due to the slight differences in specific gravity of Halotron I and Halon 1211, approximately 460 pounds of Halotron I can be placed in the existing vessel (tank) that holds approximately 500 pounds of Halon 1211. Fire performance tests have shown that Halotron I will generally suppress or extinguish fires in the same manner as Halon 1211. In considering the substitution of Halotron I for Halon 1211, the ratio for equivalency in performance is as great as 1.5 to 1 pound by weight. Halon 1211. Halon 1211 was previously the primary clean agent used by ARFF departments. Because of its ozone-depleting qualities, the production of Halon 1211 has been banned since January 1, 1994, and the discharge of this agent for training is no longer allowed. Since that time, several environmentally friendly clean agents have been developed and tested. Halon 1211 is still available through reclaiming and recycling sources.
