What is the Best Type of Fire Extinguisher for Aircraft Hangars?

NFPA requires that all aircraft hangers be properly equipped with fire extinguishers that can extinguish Class A and B fires. These guidelines are published under the NFPA 407 Standards on Aircraft Hangers. So, what is the best type of fire extinguisher for aircraft hangars? NFPA requires either Standard B:C fire extinguishers or multi-purpose dry chemical fire extinguishers be used in aircraft hangers. Areas such as offices, storage rooms, or rooms where common combustible fires are likely to occur need to be fitted with a Class A fire extinguisher. Rooms where flammable liquids are used or stored are to be fitted with a Class B rated fire extinguisher. Because aircraft hangars store expensive equipment and airplanes, many aircraft hangar managers opt to use Halotron fire extinguishers that are capable to extinguishing class A, B and C fires and won’t damage or corrode sensitive electrical equipment of the airplanes. An additional fire extinguisher model that is common among aircraft hangers are Carbon Dioxide fire extinguishers Below is an example of fire extinguisher placement in an aircraft hangar.

Fire Extinguishers and Aircraft Hangers

Aircraft hangers are categorized into four different groups, designated Group I, Group II, Group III, and Group IV. Each category has separate rules and regulations regarding the use and placement of fire extinguishers. Group I has the largest fire area allowance, Group II the next largest, and Group III has the smallest fire surface allowance. Group IV is categorized differently than the other groups as it designates a structure with a rigid steel frame that is covered by a membrane fabric with no limit to the fire area. All aircraft hangars are required to be fitted with an adequate number of fire extinguishers per NFPA 10 guidelines. The distribution of fire extinguishers in aircraft storage and servicing areas must be in accordance with the extra hazard classification for Class B fires and hazards. The size of the fire area for group I, II and III aircraft, storage and maintenance areas is determined by the construction type. Below is a chart that shows the various construction types and corresponding group classification.

NFPA-409 Construction Type
Placement and distribution of fire extinguishers is largely dependent upon the analysis of the aircraft hangars construction type, group classification, and occupancy rating (Light, Ordinary or Extra hazard occupancy). The area’s where common combustible fires may occur need a Class A extinguisher, Class B fire extinguisher in areas where flammable liquids are a potential fire hazard, and class C for areas where electrical fires are likely to occur.
