Which color is used in the ERG to indicate the section containing initial isolation and protective action distances when a chemical name is highlighted?

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

Answer: (B)

Color coding helps responders jump straight to the section that gives initial isolation distances and protective actions when a chemical name is highlighted. The color used for that section is green, so you can quickly locate the necessary perimeter and actions without wading through other information. This immediate link between the highlighted chemical and its green section speeds up decision-making and reduces confusion in the field. Other colors in the ERG point to different kinds of information, so they don’t indicate the initial isolation distances.
