A cleaning solvent liquid having a flash point at or above 200°F requires a classification of which type?

1. Type I

2. Type II

3. Type III A

4. Type III B

The correct answer is: Type III B

In the context of flammable and combustible liquids, classification is primarily determined by the flash point of the liquid. A cleaning solvent with a flash point at or above 200°F is classified as a Type III B liquid. Type III B liquids are defined as those with a flash point between 140°F and 200°F. However, it is essential to note that cleaning solvents generally fall into the category of combustible liquids rather than flammable. The important distinction here is how these classifications are used in storage and handling regulations within safety codes, including the National Fire Protection Association (NFPA) standards. Liquids classified as Type I, Type II, and Type III A have different flash point ranges. Type I includes liquids with flash points below 100°F, which would not apply here. Type II liquids have flash points at or above 100°F but below 140°F, while Type III A substances fall between 140°F and 200°F. Given the specific flash point of the solvent in question is at or above 200°F, it would officially be classified under this standard as Type III B. Understanding these classifications is vital for ensuring proper safety measures are in place when handling, storing, or transporting such chemicals, as each class has specific
