Materials of construction 1 ...... Yes ...... Yes ...... Yes. Detectors 2 ...... No ...... Yes ...... Yes. Liner 3 ...... No ...... No ...... Yes. Locating device 4 ...... No ...... Yes ...... Yes. 1 Material: The material used to construct each enclosed stowage compartment must at least be fire resistant and must meet the flammability standards established for interior components according to the requirements of § 25.853. For compartments less than 25 ft3 in interior volume, the design must ensure the ability to contain a fire likely to occur within the compartment under normal use. 2 Detectors: Enclosed stowage compartments equal to or exceeding 25 ft3 in interior volume must be provided with a smoke or fire detection system to ensure that a fire can be detected within a 1-minute detection time. Flight tests must be conducted to show compliance with this re- quirement. Each system (or systems) must provide: (a) A visual indication in the flight deck within one minute after the start of a fire; (b) An aural warning in the crew rest compartment; and (c) A warning in the main passenger cabin. This warning must be readily detectable by a flight attendant, taking into consideration the posi- tioning of flight attendants throughout the main passenger compartment during various phases of flight. 3 Liner: If it can be shown that the material used to construct the stowage compartment meets the flammability requirements of a liner for a Class B cargo compartment, then no liner would be required for enclosed stowage compartments equal to or greater than 25 ft3 in interior vol- ume but less than 57 ft3 in interior volume. For all enclosed stowage compartments equal to or greater than 57 ft3 in interior volume but less than or equal to 200 ft3, a liner must be provided that meets the requirements of § 25.855 at Amendment 25–60 for a Class B cargo compartment. 4 Locating Device: Crew rest areas that contain enclosed stowage compartments exceeding 25 ft3 interior volume, and that are located away from one central location, such as the entry to the crew rest area or a common area within the crew rest area, would require additional fire pro- tection features and/or devices to assist the firefighter in determining the location of a fire.
