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 price was reasonable, the time to complete the course was manageable, and the flexibility the online training allowed made it easy to complete.

I love that the instructor emphasized the thought process behind the regs.

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

Very witty instructor, made the long times sitting bearable. One of the few training courses I can say I actually enjoyed.

John Hutchinson

Senior EHS Engineer

I attended training from another provider and learned absolutely nothing. Lion is much better. Hands down.

Nicole Eby

Environmental Specialist

The instructor was very very informative, helpful, understandable and pleasant. This course answered many questions I had, being new to this industry.

Frances Mona

Shipping Manager

Having the tutorial buttons for additional information was extremely beneficial.

Sharon Ziemek

EHS Manager

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

This training broke down the regulations in an easy-to-understand manner and made them less overwhelming. I now feel I have the knowledge to make more informed decisions.

Lion is my preferred trainer for hazmat and DOT.
