Hazardous Materials Incident Considerations

  • Chapter 2

    • Hazardous Materials Reference Sources

Haz mat reference sources l.jpg
Haz Mat Reference Sources

  • Session Objectives

    • The student will be able to:

      • Identify the types of hazard and response information available

      • Explain the advantages and disadvantages of each resource

      • Utilize various reference sources to identify hazard and response information about various hazardous materials

Hazardous materials information l.jpg
Hazardous Materials Information

  • The key to success is knowing:

    • What information is needed

    • How to access it

    • How to properly interpret and utilize it

Hazardous materials information4 l.jpg
Hazardous Materials Information

  • A working knowledge of the involved chemicals is needed to make sound decisions on:

    • Protective actions

    • Control zones

    • Levels of PPE

    • Other tactical operations

Information sources l.jpg
Information Sources

  • Personnel at the site

  • Books

  • Computer data bases

  • Material Safety Data Sheets (MSDS)


Hazardous materials information and reference sources l.jpg
Hazardous Materials Information and Reference Sources

  • Types of Information Needed

    • Physical properties

    • Chemical Properties

Physical properties l.jpg
Physical Properties

  • Vapor density

  • Water solubility

  • Specific gravity

  • Boiling point

  • Flash point

  • Flammable/explosive limits

  • Ignition temperature

Chemical properties l.jpg
Chemical Properties

  • Corrosivity

  • Toxicity

  • Radioactivity

  • Oxidizing potential

  • Reactivity

On site personnel l.jpg
On-Site Personnel

  • Can be a valuable source of information on:

    • what happened

    • what materials are involved

    • what the conditions are

Technical experts l.jpg
Technical Experts

  • On site technical experts

  • Industry experts

  • Always confirm information with at least two other sources

  • Beware of “no big deal” syndrome

Hazardous materials reference books l.jpg
Hazardous Materials Reference Books

  • To be useful, books should meet three requirements:

    • easy to access information

    • accurate

    • understandable

  • Training on the use of each book is a must!

Reference library l.jpg
Reference Library

  • Maintain a reference library on response vehicles

  • Updated on a regular basis

  • Use at least three sources of information

  • Know which book will be the best source for a specific type of information

North american emergency response guide book l.jpg
North American Emergency Response Guide Book

  • Designed for First Responders

  • Good source of information on initial actions

    • isolation and protective actions

    • PPE

    • effects on target organs

  • Lists ionizing potentials for chemicals

Condensed chemical dictionary l.jpg
Condensed Chemical Dictionary

  • Provides three distinct types of information:

    • descriptions of chemicals, raw materials, processes, and equipment

    • expanded definitions of chemical entities, phenomena, and terminology

    • descriptions or identifications of a wide range of trademarked chemical products

Nfpa fire protection guide on hazardous materials l.jpg
NFPA Fire Protection Guide on Hazardous Materials

  • Excellent source for fire-related data.

    • It contains four sections:

      • Section 49 contains information on chemical properties

      • Section 325M discusses the fire hazard properties of flammable liquids, gases and volatile solids

      • Section 491M is a listing of known chemical reactions

      • Section 704 Identification System
