Which hazard class is associated with flammable liquids?

The classification of hazardous materials is essential for understanding their properties and the risks they present. Flammable liquids are categorized under Class 3 according to the Hazardous Materials Regulations (HMR). This class specifically includes liquids that have a flash point of 60 degrees Celsius (140 degrees Fahrenheit) or lower, meaning they can ignite easily at relatively low temperatures.

Class 3 encompasses a wide variety of substances such as gasoline, alcohol, and certain solvents. Proper labeling and handling of materials in this class are critical to ensure safety during transportation and storage, as these liquids can pose significant fire hazards.

In contrast, other classifications such as Class 1 generally pertain to explosives, Class 5 relates to oxidizers and organic peroxides, and Class 7 is designated for radioactive materials. Each of these classes addresses different types of hazards, emphasizing the importance of accurate classification in maintaining safety standards.
