Hazmat Awareness · Chapter 1

Introduction to Hazardous Materials

S1 — Hazardous Materials Overview

Why this chapter matters

First responders must assume unknown releases may be hazardous until proven otherwise; awareness stops at recognition, protection, and notification.

Learning objectives (7)

  1. Define hazardous material — A substance that poses an unreasonable risk to health, safety, property, or the environment when transported, stored, or used.
  2. Describe awareness-level scope — Recognize the presence of hazmat, protect self and public from exposure, and notify the chain of command without attempting control or cleanup.
  3. Contrast responder competency levels — NFPA 470 organizes awareness, operations, technician, and specialist missions with increasing entry and mitigation authority.
  4. List awareness stop lines — Do not enter the hot zone, do not contact the product, and do not attempt confinement or suppression beyond agency policy.
  5. Identify common incident settings — Differentiate fixed facilities, transportation releases, and intentional or WMD-scale indicators for defensive size-up.
  6. Explain exposure vs contamination — Exposure is contact with a hazard; contamination is the presence of hazardous material on people, equipment, or the environment.
  7. State CHEMTREC role — CHEMTREC provides 24/7 technical information on hazardous materials in transport for responders and industry.
