Who Should Take This Course?

Our online DOT HAZMAT Training: Function Specific – Hazard Classes and Divisions course is designed for Hazmat employees involved with hazardous materials transportation, such as shipment, manufacture, or carrying. This course will teach students about the 9 hazard classes and their divisions in the Hazardous Materials Table (HMT). The training will help students identify hazards and learn how materials in each class are handled, packaged, stored and transported. This course meets the requirements for 49 CFR 172.704(a)(2)(i).

If you took our DOT HAZMAT Training: Basic General Awareness (4 Hours) course, this function-specific class will provide expanded training regarding placarding. If you took our DOT HAZMAT Training: General Awareness/Function Specific (10 Hours) course, this course’s contents were included.

Course Objectives

The objective of this DOT HAZMAT Hazard Classes and Divisions course is to meet the Federal Department of Transportation (DOT) training requirements for 49 CFR 172.704(a)(2)(i).

Per 49 CFR 172.704(a)(2)(i):

Function-specific Training. (i) Each hazmat employee must be provided function-specific training concerning the requirements of this subchapter, or exemptions or special permits issued under subchapter A of this chapter, that are specifically applicable to the functions the employee performs.

Learning Objectives

After completing this course, the student should be able to:

  • Understand hazardous materials hazard classes and divisions;
  • Understand the types of hazards in the divisions;
  • Have knowledge of Other Regulated Materials (ORM);
  • Describe forbidden materials for transport.


Per DOT Hazmat Training Requirements, a complete curriculum must include:

General Awareness Training (Basic or Advanced)

Function-specific and Modal-specific Training

Function-specific Training

Function-specific training is required hazardous materials training specific to the functions an employee actually performs. We offer the following function-specific course options, which may be taken separately or are already included within the DOT Hazmat: General Awareness/Function Specific (10 Hour) course (with the exception of the Shipping Batteries course.)

* Additional function-specific training may be required to prepare you for the specific duties you perform on the job. 

Modal-specific Training

Modal-specific training is specific to the mode of transportation that will be used to tranport hazardous materials. We offer four DOT Hazmat modal-specific courses:

Security Awareness Training

We offer a 100% Online DOT Hazmat Security Awareness training course. DOT Hazmat Security Awareness training is also included within our DOT Hazmat General Awareness/Function Specific (10 Hour) course and our DOT Hazmat Basic General Awareness (4 Hour) course.

Safety Awareness Training

We are working on Online courses to help workers meet this requirement. Coming soon!

In-depth Security Training (if applicable)

When an employer is required by 49 CFR 172.800(b) to have an in-depth Security plan, then in-depth Security training is also required. This site-specific training covers actions taken by employees according to the employer’s plan. We don’t currently offer in-depth security training.

Driver Training for Motor Vehicle Operators (if applicable)

Motor vehicle drivers who transport hazardous materials must have training on the safe transportation of hazardous materials by highway. A variety of driver safety courses may be needed. We do not currently offer driver training.

HAZMAT Employers are required to train new HAZMAT Employees within 90 days of employment or assuming new related job responsibilities. Direct supervision is required of the employee performing a hazardous material function until training is complete. DOT requirements specify HAZMAT employees need to be retrained and tested at least once every three years. However, the FAA, under 14 CFR, requires air carrier employees to be trained every two years. DOT and FAA require employers to maintain training records.

Hazmat Employer

Per the U.S. Department of Transportation, a Hazmat Employer is a person whose employee(s) perform the following functions:

  • Transport hazardous materials (hazmat) in commerce;
  • Cause hazmat to be transported or shipped in commerce; or
  • Represent, mark, certify, sell, offer, recondition, test, repair, or modify packagings as qualified for use in the transportation of hazmat.

The term “hazmat employer” also includes any department, agency, or instrumentality of the United States, a State, a political subdivision of a State, or an Indian tribe engaged in offering or transporting hazmat in commerce.

Hazmat Employee

Per the U.S. Department of Transportation, a Hazmat Employee is a person who is employed by a hazardous materials employer and directly affects hazardous materials (hazmat) transportation safety.

This would include an owner-operator of a motor vehicle which transports hazmat, and a person (including a self-employed person) who:

  • Loads, unloads, or handles hazmat;
  • Tests, reconditions, repairs, modifies, marks, or otherwise represents packagings as qualified for use in the transportation of hazmat;
  • Prepares hazmat for transportation;
  • Is responsible for safety of transporting hazmat; or
  • Operates a vehicle used to transport hazmat.

Additional Training

Please note that this this HAZMAT DOT Hazards and Divisions course is not meant to replace company-specific or function-specific training provided by your employer on equipment use and procedures for your particular work environment. You must be trained by your employer on the hazards, equipment, engineering and administrative controls, safe work practices and emergency plans specific to your role and workplace. Employers need to evaluate employee needs for additional DOT hazardous material training and training in the use of personal protective equipment used on the job.

In ALL situations, employers are required to ensure their employees are adequately trained to do their job.
