What is the fire point of a volatile combustible substance?

The fire point of a volatile combustible substance is defined as the lowest temperature at which it continues to burn after ignition. This concept is crucial in fire science because it indicates that once the substance has been ignited, it will sustain combustion as long as the temperature remains at or above this level.

Understanding the fire point helps in assessing the flammability and potential hazards associated with various substances. In practical terms, if a substance is at its fire point and is ignited, it will not only catch fire but also maintain the combustion process, which is essential for fire safety assessments. Thus, recognizing this temperature can guide safety protocols and handling practices for potentially hazardous materials in various industries.
