What is a major characteristic of Class 3 hazardous materials?

Class 3 hazardous materials are specifically categorized as flammable liquids. This classification includes substances that can easily ignite and burn at relatively low temperatures, presenting significant fire hazards during transport and handling. Materials such as gasoline, alcohol, and various solvents fall under this category.

The key factor distinguishing Class 3 materials is their flash point, which is the temperature at which they can form ignitable mixtures with air. This critical characteristic makes them particularly dangerous in an accident or spill scenario, as they can lead to fires that spread quickly and pose risks to both health and property.

In the context of hazardous materials transportation, understanding this characteristic is essential for ensuring compliance with safety regulations, proper packaging, labeling, and response procedures in case of emergencies. Recognizing the properties of flammable liquids allows drivers and safety personnel to take appropriate precautions when handling these substances.
