What are the classes to train for DOT hazmat shipping?
April 18, 2023

Transporting hazardous materials is no small feat. Companies dealing with hazmat must adhere to stringent regulations set forth by the US Department of Transportation (DOT) to ensure the safety of people, property, and the environment.

Navigating these regulations is complex and can be daunting, so partnering with a seasoned expert like CARGOpak Corp is essential to ensure safety and compliance.

This blog gives an overview of the classes for DOT hazmat shipping training and shows the range of materials classified as hazardous and the importance of their proper handling.

Class 1: Explosives

Explosives are materials that can detonate or cause a violent reaction, releasing energy as:

  • Shock wave
  • Gas
  • Heat

They are further subdivided into six divisions based on their hazard level. The wide range of explosive materials and their varying hazard levels make it difficult for companies to navigate the transportation requirements without a consultant's support.

Class 2: Gases

This class covers compressed, liquefied, or dissolved gases, including:

  • Flammable
  • Non-flammable
  • Toxic gases

Special precautions are required to ensure the safe transportation of these volatile substances. Companies may need expert guidance to identify and implement the appropriate safety measures for the materials.

Class 3: Flammable Liquids

Flammable liquids have a flashpoint of no more than 140.9°F and present a significant fire hazard during transportation. Proper handling and containment methods are crucial to minimizing the risk of accidents.

Class 4: Flammable Solids, Spontaneously Combustible Materials, and Dangerous When Wet Materials

This class includes materials that:

  • Ignite
  • Spontaneously combust
  • Emit flammable gases when exposed to water

They require special care and packaging to ensure safety during transport.

These materials' unique and varied hazards make it difficult for companies to address their transportation needs without expert advisement.

Class 5: Oxidizing Substances and Organic Peroxides

Oxidizers and organic peroxides cause the combustion of other materials. These substances require specific handling and storage procedures to minimize the risk of fire or explosion.

Class 6: Toxic and Infectious Substances

Toxic substances can cause injury or death if people come into contact with them in a number of ways, whether:

  • Ingested
  • Inhaled
  • Absorbed through the skin

Infectious substances cause disease in humans or animals. Both require strict safety measures during transportation to protect public health. Companies may struggle to maintain compliance with these safety measures without an outside consultant.

Class 7: Radioactive Materials

Radioactive materials release radiation, which poses serious health risks. Their transportation is heavily regulated, with strict guidelines to ensure the safety of those involved with shipping as well as bystanders.

The high risk and specialized regulations make it challenging for companies to ensure compliance without the help of a consultant.

Class 8: Corrosive Substances

Corrosive substances damage exposed body parts and skin, metals, and other materials.

To prevent property damage and protect those involved with shipping, they must be adequately contained and handled to prevent accidents.


Class 9: Miscellaneous Hazardous Materials

This class includes any other hazardous materials not covered by the previous eight classes. Examples include:

  • Environmentally hazardous substances
  • Asbestos
  • Lithium batteries

The broad scope of this class makes it difficult for companies to understand and comply with transportation regulations fully. An expert consultant can perform on-site audits to assess the presence of hazardous materials and provide customized guidance for their safe transportation.
