What should responders do with runoff from emergency decontamination?

• A. Divert into an area where it can be treated or disposed of later
• B. Store it for later disposal
• C. Evaporate it on-site
• D. Ignore it

Answer: (A)

Managing runoff from emergency decontamination centers on preventing contaminated water from spreading and entering the environment or water supplies. The best approach is to divert that runoff into an area designed for containment where it can be treated or disposed of later. This keeps the water gathered in a controlled space so it can be processed by the proper facility and disposal path, reducing exposure to responders and the public and meeting regulatory requirements. Setups typically channel the water to a sump or lined containment area, with plans for proper treatment or removal to an approved disposal site.

Evaporating the runoff on-site can release hazardous vapors and move contaminants into the air, which creates new exposure risks. Simply storing the runoff at the scene can lead to capacity problems and potential leaks or spills before proper disposal. Ignoring the runoff is dangerous and violates safety protocols.
