AMC 25.851(a)(2) Hand fire extinguishers ED Decision 2012/008/R There should be at least one fire extinguisher suitable for Class B and C fires installed in each pilot’s compartment. Additional extinguishers may be required for the protection of other compartments accessible to the crew in flight (e.g. electrical equipment bays) or from consideration of [CS 25.851(a)(2)](#_DxCrossRefBm1709821316). Based on EU legislation[[5]](#_ftn5), for new installations of hand fire extinguishers for which the certification application is submitted after 31 December 2014, Halon 1211, 1301 and Halon 2402 are unacceptable extinguishing agents. The hand fire extinguishers and related agents listed in the FAA Advisory Circular AC 20-42D are considered acceptable by the Agency. See [AMC 25.851(c)](#_DxCrossRefBm1709821323) for more information on Halon alternatives. NOTE: Dry chemical fire extinguishers should not be used in pilot compartments because of the adverse effects on vision during discharge and, if non-conductive, interference with electrical contacts by the chemical residues.
