What should be the first action in a HAZMAT clean-up operation?

The first action in a HAZMAT clean-up operation is to conduct a site assessment for contamination. This step is crucial because it allows responders to identify the types and extent of hazardous materials present on the site. By assessing the situation, responders can gather important information that will guide further actions, ensure safety, and determine the appropriate resources and procedures needed for an effective clean-up. This assessment includes evaluating the risks to responders, the environment, and the surrounding community.

Understanding the site's specific hazards helps in establishing control measures, protective equipment requirements, and informs the decision on whether it is safe to begin clean-up operations or if external help is necessary. It sets the foundation for an organized and effective response, ensuring that all subsequent actions are informed and targeted.
