Which type of flammable liquids has a flash point below 73 degrees F and a boiling point at or above 100 degrees F?

1. Class 1A

2. Class 1B

3. Class 1C

4. Class 2

The correct answer is: Class 1B

The correct answer highlights the classification of flammable liquids based on their flash points and boiling points, which are critical factors in assessing their hazard potential. Flammable liquids that are categorized in this specific class possess a flash point below 73 degrees Fahrenheit and a boiling point at or above 100 degrees Fahrenheit. This definition aligns precisely with the characteristics of Class 1B liquids, which are indeed defined by these attributes. The low flash point indicates that these liquids can ignite easily at relatively low temperatures, presenting risks in various environments. At the same time, their boiling point being at or above 100 degrees Fahrenheit suggests they can exist in a liquid state at typical ambient conditions, which is a key consideration for safety professionals when evaluating fire hazards. Understanding these classifications is vital for ensuring safe handling, storage, and transportation of flammable liquids, as they serve as a guideline for emergency responders and safety managers in creating safety protocols that mitigate risks associated with fire and explosion.
