ABSTRACT:
A method of purging an enclosed space of an explosive or combustible gas or vapor comprises filling the space with a foam the bubbles of which are filled with a preprepared gaseous mixture of air and a non-toxic fire-suppressant gas, such as bromotrifluoromethane, in predetermined proportions and allowing the foam to decay. The proportions of air and said fire-suppressant gas in the gaseous mixture are such that when the foam decays the gaseous mixture remaining in the tank and freed by the decay of the foam is capable of supporting human life.
