Course Length: 25 minutes

Overview: Hazardous materials (hazmat) are substances or materials that the U.S. Department of Transportation (DOT) has determined are capable of posing an unreasonable risk to health, safety, and property when transported in commerce.

Hazmat employees are likely aware of the Hazardous Materials Regulations (HMR), which are a set of rules established by The Pipeline and Hazardous Materials Safety Administration (PHMSA) to ensure hazmat is packaged and handled safely during transport.

The Hazardous Materials Table (hazmat table) is an informational list of over 3,000 hazardous materials, located within the HMR. As a part of hazmat employees’ jobs, they are responsible for understanding how to read the hazmat table.

This course is designed to help satisfy the hazmat function-specific training requirements (49 CFR 172.704) regarding the hazmat table.

Please note: 49 CFR 172.704(d) of the HMR requires each hazmat employer to create and retain a record certifying the current training of each hazmat employee. It is the responsibility of the hazmat employer to complete additional company-specific training in order to formally certify each student. Trainers may use the J. J. Keller-issued certificate for compliance with the recordkeeping requirements in Section 172.704(d)(3). The trainer and the trainer’s company are considered the “person providing the training” in Section 172.704(d)(4). Because of this, trainers should maintain additional records documenting a description or copy of the additional company-specific training materials provided to each student.


Hazmat: The Hazardous Materials Table assumes the learner has Hazmat General Awareness, Security Awareness, and Safety knowledge already gained from experience or successful completion of appropriate training. Specifically, the learner must be able to:

  • Identify the required training all hazmat employees must receive
  • Determine if a material is hazardous
  • Recognize the hazard classes and divisions used to identify hazardous materials
  • Recall what makes a material a hazardous substance, hazardous waste, marine pollutant, or elevated-temperature material.
  • Indicate the importance of the Hazmat Table
  • Communicate a material’s hazards through the use of shipping papers, markings, labels, and placards
  • Recognize potential hazmat security threats and ways to reduce them
  • Identify suspicious behaviors and describe how to report suspicious activity
  • List precautions drivers should take to keep hazmat safe while en route to its destination
  • Discuss the emergency response information requirements
  • Describe the types of safety training your employer may provide to keep you safe while working around hazmat

These prerequisites can be fulfilled by using J. J. Keller’s Hazmat: General Awareness TrainingHazmat: Safety Training, and Hazmat: Security Awareness Training courses.


After completing this course, learners will be able to:

  • Explain what the hazmat table is and why it is important in the hazmat transportation process
  • Navigate the hazmat table to verify information regarding hazardous materials
