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..."

These are the best classes I attend each year. I always take something away and implement improvements at my sites.

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

Bryce Parker

EHS Manager

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.

Linda Arlen

Safety & Environmental Compliance Officer

The instructor took a rather drab set of topics and brought them to life with realistic real-life examples.

Tom Berndt

HSE Coordinator

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

As always, Lion never disappoints

Paul Resley

Environmental Coordinator

Lion is at the top of the industry in compliance training. Course content and structure are updated frequently to make annual re-training enjoyable. I like that Lion has experts that I can contact for 1 year after the training.

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

Matt Sabine

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