In the ERG, which section contains evacuation distances and water-reactive substances?

• A. UN ID numbers listed numerically
• B. Chemical names listed alphabetically
• C. Evacuation distances and water-reactive substances
• D. Guide pages with precautionary information

Answer: (C)

That part of the ERG is where responders find the exact distances needed to keep people safe and the notes on materials that react with water. Evacuation distances tell you how far to isolate and move people away from a spill or release, while the water-reactive substances list warns about materials that can react violently with water, changing the risk and the appropriate response. Having both pieces of information in the same section lets you decide quickly on protective actions without cross-referencing multiple places. Other sections focus on identifying the material or on general precautions, but they don’t provide these combined, action-focused details. So the section that contains both evacuation distances and water-reactive substances is the one you’d use for those critical safety parameters.
