Which of the following best describes a characteristic of Category 3 flammable liquids?

The correct description of Category 3 flammable liquids is that their flash point is between 73.4°F and 140°F. This classification is significant in understanding the handling and storage requirements for these liquids in industrial settings.

Category 3 liquids are considered flammable because they can ignite at elevated temperatures. The flash point specifically indicates the lowest temperature at which the vapor of a liquid can ignite in the presence of an ignition source. Therefore, distinguishing Category 3 from other categories helps in assessing safety measures, including ventilation, fire suppression systems, and managing potential exposure to heat sources.

The definition clearly outlines that Category 3 includes liquids whose flash point falls within that specified range, emphasizing the importance of properly identifying materials by their fire hazards in order to implement appropriate safety protocols.
