What is the ignition temperature range of propane?

The ignition temperature range of propane falls between 920 to 1120 degrees Fahrenheit. This is the temperature at which propane vapor can ignite and sustain combustion when mixed with air. Understanding this range is crucial for fire investigation technicians, as it helps identify conditions under which propane might ignite in various scenarios, including accidental fires, explosion investigations, or arson cases.

Knowing the ignition temperature also supports the evaluation of ignition sources that may have interacted with propane fuel. This knowledge allows investigators to reconstruct the sequence of events leading up to a fire incident accurately. The specific range of 920 to 1120 degrees Fahrenheit reflects propane's chemical properties and helps differentiate it from other fuels, enhancing the effectiveness of fire prevention and safety measures.
