Halon 1211 was one of the most prosperous, as well as combined TMB pressurized with halon 1211 and nitrogen was named Boralon and was employed experimentally through the Los Alamos Countrywide Laboratory for use on atomic metals, using sealed cylinder extinguishers made by Metalcraft and Graviner which eliminated the dampness contamination issue. TMB/Boralon was deserted in favor of much more multipurpose brokers, though it remains to be outlined in the majority of US firefighting literature.[39]
