Which category of flammable liquid has a flash point of less than 73.4 F and boiling point ≤ 95 F?

• A. Category 1
• B. Category 2
• C. Category 3
• D. Category 4

Answer: (A)

The correct answer is indeed Category 1. This category is defined by the specific criteria for flammable liquids, particularly focusing on flash points and boiling points. A flash point of less than 73.4°F indicates that these liquids can easily ignite and present significant fire hazards at relatively low temperatures. Additionally, the boiling point of 95°F or lower signifies that these liquids can also vaporize easily at room temperature, further increasing their potential for ignition in the presence of an ignition source. Therefore, Category 1 liquids are among the most dangerous types due to their high volatility and risk of combustion, necessitating stringent safety measures when handling them. Other categories, such as Categories 2, 3, and 4, have higher thresholds for flash points and boiling points, which significantly reduces their volatility and potential for ignition. Understanding these classifications is crucial for ensuring appropriate safety protocols and handling procedures in environments where flammable liquids are present.
