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..."

No comparison. Lion has the best RCRA training ever!!

Matt Sabine

Environmental Specialist

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

Teresa Arellanes

EHS Manager

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

Given the choice, I would do all coursework this way. In-person courses go very fast without the opportunity to pause or repeat anything.

Ellen Pelton

Chemical Laboratory Manager

One of the best trainings I have ever received!

Brandon Morfin

EH&S Manager

We have a very busy work schedule and using Lion enables us to take the course at our own time. It makes it easy for me to schedule my employees' training.

Timothy Mertes

Hazmat Shipping Professional

The instructor was very dedicated to providing a quality experience. She did her best to make sure students were really comprehending the information.

Stephanie Venn

Inventory Control Specialist

The training was impressive. I am not a fan of online training but this was put together very well. I would recommend Lion to others.

Donnie James

Quality Manager

Lion's online training is more comprehensive, has better slides, and is a superior training experience than what I would get from other trainers.

Robert Brenner

District Environmental Manager

I tried other environmental training providers, but they were all sub-standard compared to Lion. I will not stray from Lion again!
