What is the DOT hazard class designated for gases?

The Department of Transportation (DOT) designates Class 2 as the hazard class specifically for gases. This classification encompasses a variety of gas types, including compressed gases, liquefied gases, and gases that can be hazardous due to their flammability, toxicity, or reactivity.

The significance of Class 2 lies in its subcategories:

• Division 2.1 includes flammable gases, which can ignite and cause fires or explosions.

• Division 2.2 covers non-flammable, non-toxic gases, which, while not immediately dangerous, can still pose risks in terms of pressure and displacement of oxygen.

• Division 2.3 is reserved for toxic gases that can be hazardous to health even at low concentrations.

Understanding the classification ensures that emergency responders and transporters can effectively manage the risks associated with different types of gases during accidents or hazardous material incidents. Proper handling and emergency procedures for Class 2 materials are crucial for ensuring safety in both transportation and firefighting scenarios.
