What is a hazardous substance?

OSHA developed the HAZWOPER Standard to protect emergency responders, site cleanup workers, and others who may be exposed to "hazardous substances." In the HAZWOPER regulations, OSHA defines "hazardous substances" to include four categories:

"CERCLA Hazardous Substances"
(Listed in 40 CFR 302.4)

The Comprehensive Environmental Response, Compensation, and Liability Act (CERCLA) authorizes US EPA to maintain a list of substances that can damage the environment if released. The list of CERCLA hazardous substances includes hundreds of substances, from acetone and ammonia to xylene and zinc.

"Hazardous Materials"
(As defined by 49 CFR 171.8)

The US Department of Transportation (DOT) defines a “hazardous material” as any substance or material that meets one or more of the criteria of a Hazard Class or Division described in 49 CFR 173, or any material that does not meet those criteria but DOT deems a hazardous material (e.g., Class 9).

"Hazardous Waste"
(As defined by 40 CFR 261.3)

Under the Resource Conservation and Recovery Act (RCRA), a hazardous waste is a waste that either:

Exhibits one or more hazardous waste characteristics (ignitability, corrosivity, reactivity, or toxicity), or
Is described on one of the lists of hazardous wastes in the RCRA regulations (F, K, P & U).

"Biological agents"
and "other disease-causing agents"

Agents "...which after release into the environment and upon exposure, ingestion, inhalation, or assimilation into any person...will or may reasonably be anticipated to cause death, disease, behavioral abnormalities, cancer, genetic mutation, physiological malfunctions, or physical deformation..."

The instructor clearly enjoys his job and transmits that enthusiasm. He made a dry subject very interesting and fun.

Teresa Arellanes

EHS Manager

This was the 1st instructor that has made the topic actually enjoyable and easy to follow and understand. Far better than the "other" training providers our company has attended!

Lori Hardy

I like Lion's workshops the best because they really dig into the information you need to have when you leave the workshop.

Tom Bush, Jr.

EHS Manager

The instructor did an excellent job presenting a very dry subject; keeping everyone interested and making it enjoyable.

Marc Bugg

I used the IT support number available and my issue was resolved within a few minutes. I don't see anything that could have made it better.

Danny Province

EHS Professional

Lion provided an excellent introduction to environmental regulations, making the transition to a new career as an EHS specialist less daunting of a task. Drinking from a fire hose when the flow of water is lessened, is much more enjoyable!

Stephanie Weathers

SHE Specialist

The instructor was very engaging and helped less experienced people understand the concepts.

Steve Gall

Safety Leader

Excellent job. Made what is very dry material interesting. Thoroughly explained all topics in easy-to-understand terms.

David Hertvik

The instructor kept the class engaged and made learning fun. There was a lot of information to cover but time flew by. I will definitely use Lion in the future!
