Halon 1211 was quite possibly the most profitable, and also the blended TMB pressurized with halon 1211 and nitrogen was referred to as Boralon and was utilised experimentally because of the Los Alamos Countrywide Laboratory to be used on atomic metals, making use of sealed cylinder extinguishers made by Metalcraft and Graviner which eliminated the humidity contamination challenge. TMB/Boralon was deserted in favor of much more versatile agents, though it is still pointed out in the majority of US firefighting literature.[39]
