Fire extinguisher class D fire extinguisher agents available; some will handle multiple types of metals, others will not. TMB was used experimentally by the US Air Force, specifically with regard to B-52 engine assemblies, and was tested in modified 10-gallon wheeled CBM extinguishers. Other agents were added to suppress the methanol flare up, such as chlorobromomethane (CBM), Halon 2402, and Halon 1211, with varied success. Halon 1211 was the most successful, and the combined TMB pressurized with halon 1211 and nitrogen was called Boralon was used experimentally by the Los Alamos National Laboratory for use on atomic metals, using sealed cylinder extinguishers
Hamlet chicken processing plant fire . When the line with a customized connector was brought up to normal operating pressure, it separated from the connector at between . Hydraulic fluid spattered onto the heating lines for the cooker and immediately vaporized. This vapor then went directly into the flame of the gas-fired cooker. The vapor had a relatively low flash point and erupted into a fireball. The ruptured hydraulic line then pumped of hydraulic fluid into the fire before electrical failure shut it down. A state-of-the-art automatic carbon dioxide fire extinguisher designed to cope with such fires had been installed over the vat after a
