What is the flash point of combustible liquids?

The flash point of combustible liquids is defined as the lowest temperature at which they can form an ignitable mixture with air. Combustible liquids are typically categorized based on their flash points, which are generally higher than that of flammable liquids.

The correct choice indicates that the flash point of combustible liquids is above 100 degrees Fahrenheit, which aligns with the classification standards used within fire safety and hazardous materials handling. Specifically, combustible liquids are those with flash points that lie between 100 degrees Fahrenheit and 200 degrees Fahrenheit. This classification means that while these liquids can catch fire, they require higher temperatures to ignite compared to flammable liquids, which have flash points below 100 degrees Fahrenheit.

This understanding is crucial for fire investigators and safety professionals as it helps assess the risks associated with different liquids in scenarios involving fire hazards.
