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..."

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.

If I need thorough training or updating, I always use Lion. Lion is always the best in both instruction and materials.

Bryce Parker

This course went above my expectations from the moment I walked in the door. The instructor led us through two days packed with useful compliance information.

Rachel Stewart

Environmental Manager

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

Barry Cook

Hazmat Shipping Professional

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

Francisco Gallardo

HES Technician

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

Teresa Arellanes

EHS 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 made the class very enjoyable and catered to the needs of our group.

Sarah Baker

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

Sara Sills

Environmental Specialist

I can't say enough how pleased I was with this course! Everything finally makes sense.
