Halon 1211 was essentially the most successful, plus the merged TMB pressurized with halon 1211 and nitrogen was known as Boralon and was employed experimentally through the Los Alamos National Laboratory for use on atomic metals, working with sealed cylinder extinguishers created by Metalcraft and Graviner which eliminated the dampness contamination dilemma. TMB/Boralon was deserted in favor of more flexible agents, although it continues to be outlined for most US firefighting literature.[39]
