A 2.4m by 3.7m compartment with a ceiling height of 2.4m has a volume of 21.312m3. Based on a potential heat release of 3 MJ/m3 of air, the volume of the compartment would provide sufficient air for release of 63.936 MJ. A fire burning in this compartment with a steady heat release rate of .5 MW would consume the air in the compartment in just over two minutes or 127.8 seconds.
