What is the minimum rating for a handheld fire extinguisher required aboard an aircraft?

The minimum rating for a handheld fire extinguisher required aboard an aircraft is a 2-B:C rating. This rating indicates that the fire extinguisher is capable of handling two times the standard for Class B fires, which typically involve flammable liquids such as gasoline or oil, and is also suitable for Class C fires, which involve electrical equipment.

Having a 2-B:C extinguisher ensures that it meets the necessary safety standards for extinguishing common fire hazards that can occur in aircraft environments. The Class B portion of the rating is crucial due to the types of materials found in an aircraft, while the Class C designation signifies that it can safely be used on electrical fires without the risk of conducting electricity.

It's important for safety equipment on board to comply with these ratings to effectively manage potential fire outbreaks, providing a reliable means of protection in emergency situations while in flight or on the ground. This aligns with aviation safety regulations aimed at minimizing risks and enhancing the safety of all personnel aboard the aircraft.
