Information on health hazards is found in the Potential Hazard area of the orange guide in the Emergency Response Guidebook (ERG).

Harm Classification

Corrosive materials cause skin or tissue damage on contact.
Etiologic materials include infectious organisms.
Thermal exposure relates to extreme temperatures.
Poisonous materials are toxic via inhalation, ingestion, absorption, or skin breaks.

Safety Considerations

Sensing hazardous materials poses risks of exposure, especially through inhalation.
Personal safety assessment includes ignoring smells during incidents linked to criminal activities.

Emergency Response Guidebook

Guide number 128 corresponds to diesel fuel and gasoline.
The yellow section of the ERG lists UN/NA numbers in order.
