Which statement describes the color coding on the map overlay for chemical contamination?

• A. Yellow indicates safe zones
• B. Yellow indicates contaminated areas
• C. Yellow indicates water features
• D. Yellow indicates administrative zones

Answer: (B)

Yellow on the chemical contamination overlay marks areas that are contaminated and require protective actions. This warning color is used to signal hazard and prompt proper precautions, such as donning PPE and enforcing decontamination or exclusion zones. It helps responders quickly distinguish contaminated zones from safe areas, water features, or administrative boundaries, which are shown with other colors. Recognizing this color cue guides immediate decision-making and the implementation of appropriate control measures in the contaminated areas.
