The duration and the maximum temperature of a fire in a building compartment depends on several factors including the amount and configuration of available combustibles, ventilation conditions, properties of the compartment enclosure, weather conditions, etc. In common circumstances, the maximum temperature of a fully developed building fire will rarely exceed 1800°F. The average gas temperature in a fully developed fire is not likely to reach 1500°F. Temperatures of fires that have not developed to post-flashover stage will not exceed 1000°F.
