Question

Liquids are divided into classes based upon their flash point. Which of the following liquid classifications have a flash point at or above 100 degrees F (38 C) but below 140 degrees F (60 C)?

A) Class I
B) Class II
C) Class IIIA
D) Class IIIB

Answer 1

Class II liquids have a flash point at or above 100 degrees F (38 C) but below 140 degrees F (60 C). Examples of Class II liquids include kerosene and diesel fuel.

Step-by-step explanation:

Liquids are classified based on their flash points, which is the lowest temperature at which they can vaporize to form an ignitable mixture in air. According to the information provided, the classification we are looking for is the one where the flash point is at or above 100 degrees Fahrenheit (38 C) but below 140 degrees Fahrenheit (60 C).

Referring to the flash point scale provided, which denotes '2' as the category for flash points above 100 degrees Fahrenheit but not exceeding 200 degrees Fahrenheit, the correct liquid classification would be Class IIIA. This is because Class IIIA liquids have flash points at or above 140 degrees Fahrenheit (60 degrees Celsius), which falls outside the range specified in your question.
