The contribution which cooling of the fuel might make, to the effectiveness of vaporizing extinguishing agents has been estimated and compared with the inerting or inhibiting effect of these agents. For all agents examined the cooling effect is comparable to the inerting effect. The cooling effect can only be exercised appreciably with certain types of fire, for example spill fires. Solid carbon dioxide has a very large cooling effect and it is suggested that this agent might be used in the form of low temperature slurries in a liquid agent.
