Liquids with flash points between 100°F and 140°F are classified as what type of combustible liquid?

Liquids with flash points between 100°F and 140°F are classified as Class II combustible liquids. This classification is important in the handling and storage of these materials, as it helps to determine the appropriate safety measures and regulations that must be followed to prevent fires and ensure safe working conditions.

Class II liquids are those that can ignite under certain conditions but have a relatively higher flash point compared to Class I liquids, which have flash points below 100°F and pose a greater fire hazard. On the other hand, Class III liquids, which include Class IIIA and Class IIIB categories, have flash points above 140°F and can be considered less hazardous in terms of fire risk. Class IIIA includes liquids with flash points between 140°F and 200°F, while Class IIIB refers to those with flash points at or above 200°F.

Understanding these classifications is crucial for HVAC professionals, as it influences how they manage risks when working with different fuels and fluids. Proper training in these categories aids in compliance with safety regulations and enhances overall job site safety.
