Minimum Performance Requirement for Air Force Flightline Fire Extinguishers: Extinguishing Performance Against 3-Dimensional and Hidden Fires

摘要

This report contains requirements for extinguishing fires occurring within an engine nacelle through access ports and to extinguish pooled of flowing fuel tail pipe fires. It provides the test protocol and test apparatus requirements for assessing the capability of fire extinguishers to suppress these two specific aircraft engine fires that frequently occur on the flightline. The current Air Force flightline extinguisher uses Halon 1211, an Ozone Depleting Substance (ODS). Any agent used in an extinguisher proposed for testing would be considered a replacement for an ODS. As a replacement under Section 612 of the Clean Air Act of 1990, the agent would have to be approved as an Acceptable Halon 1211 Replacement through the EPA Significant New Alternatives Policy (SNAP) program prior to testing. These criteria are provided for the sole purpose of assessing the capability of fire extinguishers to suppress aircraft engine fires on the flightline.
