What measure specifically helps protect storm drains and water bodies during hazmat incidents?

• A. Contain spills, use booms, protect storm drains and water bodies.
• B. Ventilate the area to disperse vapors.
• C. Remove all containers to a safe distance.
• D. Pour water into drains to dilute

Answer: (D)

In hazmat response, preventing runoff from reaching storm drains and water bodies is the priority. The best approach is to contain the spill at the source and create barriers—such as booms, absorbents, and dikes—to block and divert contaminated flow away from drains and waterways. This keeps the substance on the ground where cleanup is possible and prevents it from migrating into the drainage system and ultimately into rivers, lakes, or streams. Pouring water into drains to dilute the contaminant won’t protect water bodies; it can spread the chemical, overwhelm the drainage system, and worsen environmental harm. Ventilation addresses vapors, not water protection, and removing containers or just diluting the release doesn't address the risk to waterways.
