Study Notes

Hazardous Materials Awareness Key Concepts

Compliance with local, state, and federal requirements at the HazMat Awareness level involves OSHA, DOT, and EPA.
At the awareness level, responders must recognize the presence of hazardous materials to ensure safety.

Hazard Classes and Identification

An orange diamond with an exploding circle indicates explosives (DOT Class B).
Materials that yield oxygen and enhance combustion are classified as oxidizers.
Radioactive materials fall under DOT Class 7.
DOT Class 6, Division 1, includes poisonous materials.

Bulk Material Transportation

Corrosives are transported in specialized tanks designed for that purpose.
Different tank designs are used for liquefied petroleum gas, liquefied nitrogen, and flammable liquids.

Shipping Papers and Transportation Procedures

All shipping papers must include the proper shipping name, a four-digit UN/NA number, and hazard class.
For rail transport, shipping papers are commonly held by the conductor or engineer.

Military and Sensory Clues

Military warning symbols can indicate the presence of harassing agents.
Sensory clues for recognizing hazardous materials do not include checking the health hazard section of the SDS.
Close proximity to hazardous materials can increase the risk of danger.

Identifying Hazards

Hazardous materials can harm through corrosive actions, by being etiologic (germs), thermal exposure, or poisoning from toxicity.
Exposure to corrosive materials is considered contact exposure, while inhalation risk is present when using smell for identification.

BLEVE Incidents

A BLEVE (Boiling Liquid Expanding Vapor Explosion) can create projectiles as a significant hazard.
Evacuation distances and further action at BLEVE incidents should be determined using emergency response guides.

Health Hazard Information

Information regarding a material's health hazard can be found in the orange guide pages of the ERG (Emergency Response Guide).

Evacuation Guidelines

For a compact sedan IED, an outdoor evacuation distance of 1,500 feet is necessary.
Emergency response should prioritize evacuating from any recognized or suspected gas leaks or ruptures.

Emergency Response Guides (ERG)

Guide 111 in the ERG should be used temporarily, awaiting more specific information.
Verification of product names, identification numbers, and guide numbers is crucial for accurate hazard classification.
