If you know the Chemical/Material Name:

1. Go to the Specific Material Guides
Ë locate the chemical in the alphabetical listing

2. If you are unable to locate the chemical in the Specific Material Guide:
Ë Go the Alphabetical Material Name Index
Ë locate the chemical in the alphabetical listing
Ë go to the page listed for guidance information

3. If the chemical is not found in the index, go to the HAZMAT General Response
Scheme

If you have only the UN Number for the Chemical/Material:

1. Go to the UN/NA Number Index
Ë locate the UN/NA number in the numerical listing

The information in this book was collected from a variety of sources which were reviewed by the Firefighters’ Safety Study Technical Commit-
tee and are believed to be accurate. However, the Federal Emergency Management Agency makes no claim that these data and recommenda-
tions are either correct or sufficient and assumes no liability for any adverse consequences arising from their use.

The action recommendations in this book should be considered as suggestions only. Specific circumstances at the scene of an incident as well as
the number and training of first responders will dictate what actions are actually appropriate. Final decisions are the responsibility of the Incident
Commander.

At the bottom of the page is a First Aid section. These
recommendations should be used in caring for victims who
are out of the Hot zone. Rescue of victims from within a Hot
zone should only be performed by trained personnel wearing
appropriate chemical resistant gear and is not generally a first
responder action.

Removal of hazardous material from the skin, eyes or clothing
of a victim (decontamination) is usually the most important
first aid action that can be initiated. It should be performed
only by appropriately trained and equipped individuals. Rapid
removal of the material may be the difference between a minor
injury and a serious injury. The details of decontamination
techniques are beyond the scope of this book. In general,
using large quantities of water to rinse off materials is almost
always the first choice for decontamination in the field.
Materials which are so toxic that first aid should not be
performed on contaminated victims because of the risk of
serious injury to the responder are clearly labeled. There are
very few antidotes for treating victims exposed to chemicals
and they are listed in this section for the benefit of hospital
personnel who may care for these victims. Other First Aid
information is also provided.

Finally, at the middle of the page below the first aid section is
a CHEMICAL ABSTRACTS SERVICE REGISTRY NUMBER

to each chemical by the Chemical Abstract Service. Mixtures
are usually not assigned CAS numbers. While not commonly
