What is the minimum flash point that liquid combustibles must exceed?

The minimum flash point that liquid combustibles must exceed is critical for ensuring the safety and effectiveness of training and firefighting operations. A flash point is defined as the lowest temperature at which the vapor of a combustible liquid can ignite in air. For liquid combustibles, the flash point is an essential factor in determining whether a liquid is classified as a combustible material or an ignitable material.

Selecting a flash point above 100 degrees Fahrenheit is appropriate because it provides a safer operational environment, reducing the risk of accidental ignition during training exercises. Liquids with a flash point above 100 degrees Fahrenheit are generally considered less hazardous in terms of flammability compared to those with lower flash points, which can ignite more readily at lower temperatures.

This threshold is also aligned with industry standards and safety protocols designed to protect both instructors and trainees during live fire exercises. Ensuring that all liquid combustibles used are above this flash point establishes a safer boundary for the materials being utilized in training scenarios.
