What class of combustible liquids includes those having flash points at or above 200°F?

1. Class I

2. Class IIB

3. Class IIIB

4. Class III

The correct answer is: Class IIIB

The correct classification of combustible liquids having flash points at or above 200°F falls under Class IIIB. This classification includes liquids with flash points of 200°F (93.4°C) or higher and is considered to have a lower risk in terms of flammability than liquids classified as Class I and II, which have lower flash points. Understanding the classification helps in handling and storing these materials safely. Class IIIB liquids are often not subject to the same stringent regulations as other classes of combustible liquids, as they are deemed to be less hazardous. This helps professionals in the field of safety manage risks associated with combustible liquids effectively. The options labeled as Class I and Class II are generally associated with liquids that have much lower flash points, thus posing a greater risk in various situations. Class I is for those with flash points below 100°F, while Class II typically includes liquids with flash points between 100°F and 140°F. Therefore, recognizing the properties of Class IIIB is essential for proper safety protocols and risk management concerning higher flash point liquids.
