What kind of materials would generally fall under Class 3 of the DOT hazard classification?

Class 3 of the Department of Transportation (DOT) hazard classification pertains specifically to flammable liquids. This category encompasses any liquids that can ignite and produce dangerous fire hazards under certain conditions, including those with flashpoints typically below 140 degrees Fahrenheit (60 degrees Celsius). Common examples include gasoline, alcohol, and many solvents used in industrial applications.

Flammable liquids are characterized by their ability to burn and produce vapors that can form explosive mixtures with air, which necessitates stringent handling and storage requirements to prevent accidental fires and explosions. Understanding this classification is crucial for firefighters and hazardous materials responders, as it informs the risk assessment, necessary protective measures, and emergency response strategies when dealing with such materials.
