A preliminary assessment has been made on the effectiveness or slurries or solid carbon dioxide in liquid nitrogen and in vaporizing liquid extinguishing agents for extinguishing small flammable liquid fires. The slurry was applied by being tipped onto the surface. It has been found that the slurry is more effective than the solid or liquid phases used separately. The quantities or slurry needed to extinguish a kerosine fire was substantially smaller than other extinguishing agents commonly used at the present time, and was also comparable to the quantity predicted from theoretical considerations.
