What should be the first step when responding to a hazardous materials incident?

The first step when responding to a hazardous materials incident is to assess the situation for safety. This crucial action involves evaluating the scene to identify potential hazards, including the presence of toxic substances, the risk of explosion, or other dangers. By determining the risks involved, responders can make informed decisions on how to proceed without putting themselves or others in danger.

Assessing the situation allows for appropriate protective measures to be taken, ensuring that responders can safely approach the incident. This may involve determining the wind direction, evaluating the material involved, and understanding the specific risks posed to both the responders and the surrounding community.

Starting with a safety assessment is paramount because if the responders enter a hazardous environment without understanding the risks, they could exacerbate the situation or become victims themselves. Notification of the media, starting decontamination procedures, or beginning evacuations are all actions that may be required later in the response process but should only occur once the situation has been properly assessed and a safety plan is established.
