How many fire extinguishers must each aircraft fuel servicing tank vehicle have?

The requirement for each aircraft fuel servicing tank vehicle to have two fire extinguishers rated at 20B is based on safety regulations set forth by the National Fire Protection Association (NFPA) and other aviation safety standards.

In aviation and fuel servicing operations, the proximity to highly flammable substances necessitates stringent safety measures to mitigate fire hazards. The rating of fire extinguishers indicates their effectiveness against different classes of fires, and a 20B rating means that the extinguisher can extinguish a fire involving flammable liquids, such as aviation fuel, effectively to a higher volume, providing enhanced safety and response capabilities.

Having two extinguishers allows for a backup option in case one fails to function or in scenarios where multiple fire incidents could occur simultaneously. This additional layer of precaution is critical in maintaining safety protocols during fuel servicing operations. Thus, the requirement of two fire extinguishers rated at 20B reflects a comprehensive approach to ensuring aviation safety in the handling and servicing of aircraft fuel.
