How many fire extinguishers are required and where must they be located for passenger-carry under CFR 135?

• A. Three extinguishers, located throughout the cabin.
• B. Two extinguishers, one on the flight deck and one in the passenger compartment for configurations between 10 and 31.
• C. One extinguisher located in the cockpit.
• D. Four extinguishers, distributed evenly.

Answer: (B)

In Part 135 passenger operations, fire safety equipment is tied to the number of passenger seats to ensure quick access where fires are most likely and where crew can reach it fast. For aircraft configured with 10 through 31 passenger seats, you must carry two portable fire extinguishers: one located in the flight deck and one in the passenger compartment. This setup gives the crew immediate access whether a fire breaks out in the cockpit or in the cabin, reducing the chance a fire grows before it can be suppressed.

Choosing three extinguishers in the cabin alone would not align with the standard requirement for this seating range and would neglect cockpit access. Having only one extinguisher in the cockpit leaves the cabin unprotected, and four extinguishers exceed the typical requirement for 10 to 31 seats.
