Which action should be taken first when assessing a HAZMAT incident?

The first action to take when assessing a HAZMAT incident is to ensure personal safety and assess hazards. This step is crucial because the safety of responders and the public is the top priority in any hazardous materials situation. By conducting a thorough hazard assessment, responders can identify the nature of the materials involved, the potential risks they pose, and the protective measures needed to safely manage the incident.

Assessing hazards includes evaluating the site, understanding the type of hazardous materials involved, their physical state, and determining the appropriate protective equipment and procedures. This initial assessment lays the groundwork for all subsequent actions, including whether evacuation or containment is needed and how to effectively engage other response resources.

In contrast, actions such as beginning clean-up immediately could expose responders to dangers without understanding the hazards. Engaging with the media for updates happens later in the response process, once there is a clear understanding of the situation. Contacting neighboring agencies for assistance is a necessary step, but should follow the assessment of personal safety and hazards to ensure that resources are deployed effectively and safely.
