What factors determine the minimum number of hand fire extinguishers required in passenger compartments?

The minimum number of hand fire extinguishers required in passenger compartments is primarily determined by the passenger seating capacity, the number of galleys, and their location. Passenger seating capacity is crucial because it directly relates to the potential number of individuals onboard and the extent of risk in the event of a fire. More passengers mean a higher need for accessible firefighting resources.

Additionally, the number of galleys plays an important role, as cooking equipment can be a significant fire hazard during flights. The location of the galleys also matters; extinguishers need to be placed where they can be quickly accessed in the event of a fire, which typically occurs near food preparation areas.

Type of aircraft and flight duration, while important for overall safety and risk assessments, do not directly dictate the specific number of fire extinguishers required in passenger compartments. Weather conditions and flight path typically influence operational decisions rather than safety equipment requirements, and expected passenger behavior may factor into emergency protocols but does not determine the quantity of fire extinguishers. Thus, the specified factors are the key elements in assessing the necessary fire safety equipment onboard.
