A label indicating a flammable liquid falls under which hazard classification?

• A. 1
• B. 2
• C. 3
• D. 4

Answer: (C)

A label indicating a flammable liquid falls under hazard classification 3. This classification specifically pertains to liquids that can easily ignite and burn at relatively low temperatures, typically those with a flash point of less than 60°C (140°F). Flammable liquids are considered dangerous due to their ability to create hazardous conditions if they are not handled or stored correctly, resulting in fire hazards.

Classification 3 is widely recognized in various regulatory guidelines, including those from the United Nations and the Occupational Safety and Health Administration (OSHA), which provide consistent criteria for identifying and labeling hazardous materials. Understanding this classification is crucial for ensuring proper safety measures are in place when working with solvents, fuels, or any other flammable substances.
