A review and analysis was performed on past and ongoing efforts to develop Halon 1211 alternatives. Since 1985, the U.S. Air Force (USAF) has sponsored the majority of the work. The approach has been to develop an agent that would perform the same as Halon 1211 and be suitable for use directly in the existing Halon 1211 hardware, i.e., the drop-in approach. To date, no agents have successfully met the drop-in requirements, and no alternative clean agent has been approved for military, aviation fire fighting. It is recommended that a new approach be pursued that is based on the development of fire fighting and other operational requirements. Specific tests based on the requirements need to be established and specific pass/fail criteria developed to evaluate commercially available agents. |
