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 the best RCRA training I've experienced! I will be visiting Lion training again.

Cynthia L. Logsdon

Principal Environmental Engineer

The exercises in the DOT hazardous materials management course are especially helpful in evaluating your understanding of course information.

Morgan Bliss

Principal Industrial Hygienist

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

Much better than my previous class with another company. The Lion instructor made sense, kept me awake and made me laugh!

Marti Severs

Enterprise Safety Manager

Excellent. I learned more in two days with Lion than at a 5-day program I took with another provider.

Francisco Gallardo

HES Technician

Lion courses always set the bar for content, reference, and practical application. Membership and access to the experts is an added bonus.

John Brown, CSP

Director of Safety & Env Affairs

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 was very responsive to my initial questions and the website was user friendly.

Michael Britt

Supply Chain Director

I have over 26 years of environmental compliance experience, and it has been some time since I have attended an environmental regulations workshop. I attended this course as preparation for EHS Audits for my six plants, and it was exactly what I was looking for.

Frank Sizemore

Director of Regulatory Affairs

The instructor was probably the best I ever had! He made the class enjoyable, was humorous at times, and very knowledgeable.
