Atlantic Training's "HAZMAT Labeling" HAZWOPER Video Program assists facilities in complying with the employee training requirements of OSHA's HAZWOPER regulation (29 CFR 1910.120), and instructs employees who deal with hazardous materials that they can reduce the risk of accidental exposure by using the correct labels and placards on each chemical container. Hazardous materials and waste are part of many work situations, and can be found on many types of job sites. OSHA feels that it is so important for employees to know how to recognize these potentially dangerous substances (as well as how to handle and dispose of them properly) they have mandated that anyone working with these materials receive comprehensive training in this area.


In 1976, the U.S. Environmental Protection Agency (EPA) issued the Resource Conservation and Recovery Act (RCRA) to regulate the handling of hazardous waste "from cradle to grave". Since then other regulations have followed, including OSHA's 29 CFR 1910.120, also known as HAZWOPER. As part of these regulations, there are varying requirements for employee training, depending on an employee's specific level of involvement with hazardous materials.

Areas covered in the program include:

  • where hazardous material labels are used
  • OSHA labelling requirements
  • most common labelling systems
  • DOT Hazard Class labels and placards
  • the Hazardous Materials Identification System (HMIS)
  • target organ information labels
  • the National Fire Prevention Association (NFPA) Labelling System
  • hazardous waste labels
  • … and more.

Video Transcript

There are four labeling systems that are used most often with hazardous substances. Let’s look at DOT labels first. There are strict guidelines regulating the size, shape and color of Department of Transportation Labels. You will also see placards with DOT symbols. Placards are diamond shaped, just like Hazard Class labels. For vehicles that are used to carry various hazardous materials, special "multi-paneled" placarding systems are available.
