Which color-coded section of the ERG would you consult for fire, explosion, and health hazard information about a material?

• A. Blue
• B. Green
• C. Orange
• D. Yellow

Answer: (C)

The key idea is that the orange section of the ERG houses the material-specific hazard guides, which include fire and explosion risks as well as health hazards and the recommended actions. When you identify a material (often by its UN number or name) you look up its guide in the orange pages to read exactly what hazards it poses and what steps to take in an emergency.

In practice, you’d first identify the material and find its guide number, then turn to the corresponding orange page to see the fire risk, potential for explosive release, health hazards, and the actions you should take (evacuation distances, PPE, containment steps, etc.). The other color sections provide different kinds of information—general identification, safety considerations, or procedural guidance—but they don’t give the material-specific fire, explosion, and health hazard details you need for a proper response.
