Mechanical Foam for Fighting Petrol Fires

Nature volume 162, page 158 (24 July 1948) | Download Citation



FOAM for dealing with petrol fires can be generated in two ways : by chemical reaction (chemical foam), or by mechanical agitation (mechanical or air foam). Mechanical foam is largely used in Great Britain and is produced by churning up air and water with a foam-stabilizing agent, such as saponin or soap. The foam-making branch pipe is the apparatus in general use by fire services.
