A study has been made of methods of testing small hand-portable fire extinguishers considered suitable for application to flammable liquids. The study was performed by evaluating the effectiveness of the extinguishers, in which 5 different extinguishing agents were used on 10 types of tires, selected either because they had been used in standard extinguisher tests or simulated other possible conditions of hazard. An analysis was made of the relative merit of the fires for extinguisher testing, the effect of ambient variables on the tests, and the value of the several extinguisher types for use on the fires.
