• B. Flammable liquid
• C. Oxidizer
• D. Corrosive material

Answer: (B)

A Hazard Class of 3 under the U.N. Labeling System specifically indicates a flammable liquid. This classification encompasses liquids that have a flash point of 60 degrees Celsius (140 degrees Fahrenheit) or lower. Such materials can easily form ignitable mixtures when their vapors come into contact with an ignition source, which is a critical safety concern. The labeling system helps responders and transporters quickly identify the risks associated with hazardous materials, ensuring that appropriate precautions and safety measures are taken during handling and transport.

In this context, flammable liquids can include substances such as gasoline, alcohol, and some solvents, and are known for their potential to contribute to accidents if not stored or managed properly. Understanding this classification aids individuals in recognizing hazardous materials and implementing the necessary safety protocols to handle them effectively.
