What is the first step an IC should take upon arrival at a HAZMAT incident?

Establishing command and assessing the situation is the critical first step for an Incident Commander (IC) upon arriving at a HAZMAT incident. This action allows the IC to take control of the incident scene effectively and coordinate the response efforts. By establishing command, the IC sets a clear chain of authority and communication among the responders, ensuring that everyone understands their roles and responsibilities.

Assessing the situation involves gathering critical information about the hazardous materials involved, the extent of the incident, potential risks to responders and the public, and the environmental conditions. This situational awareness is essential for making informed decisions regarding response strategies, determining evacuation zones if necessary, and implementing safety measures to protect all personnel on site.

Effective command establishment and assessment form the foundation for all subsequent actions in the incident response, including communication with the media and ensuring the safety of the public, which come at later stages.
