Training Division
Objectives
Hazardous Material
OSHA 29 CFR 1910.120
Standard of Care
Hazardous Materials Goals
**The order in which the goals are accomplished does not matter. They should be prioritized by each incident.
Levels of Training
Awareness-trained to identify a chemical and to notify the proper authorities.
Operations-trained to handle hazardous materials in a defensive manner without coming in contact with the product.
Technician-allows a responder to deal with an incident in an offensive manner.
Specialist-a person who can assist responders with information on a chemical’s make-up and reactivity hazards.(chemist)
What Info Do I Need?
Gaining Information
Reference Manuals/Books
Emergency Response Guidebook
This guide was developed by the DOT for use by first responders and others. It contains guidance helpful during the initial phases of a hazardous materials incident. Each chemical is given a guide number and this is used to gain information about the product, evacuation procedures, first aid considerations, what PPE should be used, firefighting considerations as well as other valuable information.

0-6=Acid 8-14=Base 7=Neutral
To sustain combustion, the correct mix of fuel
and oxygen (air) must be availaible. The LEL
indicates the lowest quantity of gas which must
be present for combustion and the UEL indicates
the maximum quantity of gas. The actual LEL
level for different gases may vary widely and
are measured as a percent by volume in air.
METHANE LEL=5% UEL=15%
HYDROGEN LEL=4% UEL=75%
PROPANE LEL=2.1% UEL=9.5%
ACYTELENE LEL=2.5% UEL=100%

Methods of Contamination
Decontamination
Anything or anyone entering the hot zone is considered to be contaminated and must be decontaminated before leaving that zone. This includes responders, victims, onlookers, and equipment.

Termination
Termination activities should concentrate on providing accurate information to the people who need it the most. Initially, this group is a small number of on-scene responders who may be briefed on the symptoms of a particular substance or on special recovery procedures. The termination process is divided into three phases:
