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..."

This is a very informative training compared to others. It covers everything I expect to learn and even a lot of new things.

The instructor does a great job at presenting material in an approachable way. I have been able to save my company about $30,000 in the last year with what I have learned from Lion!

Curtis Ahonen

EHS&S Manager

I can take what I learned in this workshop and apply it to everyday work and relate it to my activities.

Shane Hersh

Materials Handler

The workshop covered a lot of information without being too overwhelming. Lion is much better, more comprehensive than other training providers.

George Alva

Manufacturing 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

Process & Resource Administrator

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

Rebecca Saxena

Corporate Product Stewardship Specialist

Convenient; I can train when I want, where I want.

Barry Cook

Hazmat Shipping 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

Lion's course was superior to others I have taken in the past. Very clear in the presentation and the examples helped to explain the content presented.

George Bersik

The instructor had knowledge of regulations and understanding of real-world situations. The presentation style was engaging and fostered a positive atmosphere for information sharing.
