What class of combustible liquids includes those with flash points at or above 100°F and below 140°F?

1. Class I

2. Class II

3. Class III

4. Class IV

The correct answer is: Class II

The classification of combustible liquids is based on their flash points, which are critical for understanding their potential hazards during storage and use. For the class of combustible liquids described in the question, those with flash points at or above 100°F and below 140°F are classified as Class II liquids. Class II liquids are significant because they represent a middle category of flammable liquids, meaning they are flammable under certain conditions but not as readily as Class I liquids, which have lower flash points. Understanding this classification is essential for compliance with safety regulations, proper handling, and storage procedures. Class II liquids require specific safety measures to prevent fire hazards, particularly in environments where ignition sources may be present. This understanding helps safety professionals mitigate risks and implement appropriate safety protocols.
