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..."

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

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

My experience with Lion training, both online and in the classroom, is that they are far better organized and provide a better sequential explanation of the material.

Robert Roose

Manager, Dangerous Goods Transportation

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 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!

As always, Lion never disappoints

Lion is my preferred trainer for hazmat and DOT.

Jim Jani

Environmental Coordinator

These are the best commercial course references I have seen (10+ years). Great job!

Ed Grzybowski

EHS & Facility Engineer

Well designed and thorough program. Excellent summary of requirements with references. Inclusion of regulations in hard copy form, as well as full electronic with state pertinent regulations included is a great bonus!

Oscar Fisher

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.
