What classification is given to flammable liquids with flash points below 73 degrees Fahrenheit and boiling points below 100 degrees Fahrenheit?

1. Class 1A

2. Class 2B

3. Class 3C

4. Class 4D

The correct answer is: Class 1A

Flammable liquids with flash points below 73 degrees Fahrenheit and boiling points below 100 degrees Fahrenheit are classified as Class 1A liquids. This classification reflects the significant risk associated with these substances, as they ignite easily and can vaporize quickly in normal atmospheric conditions, creating flammable mixtures with air. The characteristics of having both a low flash point and a low boiling point indicate a high potential for fire hazards, making safety precautions critical when handling or storing these materials. Understanding these classifications is essential for implementing proper safety measures in workplaces that handle flammable substances.
