What is an early step to take when responding to a hazardous materials incident?

Isolating the area is critical in the initial response to a hazardous materials incident because it helps to contain the hazard and prevent further exposure to both the responders and the public. By establishing a perimeter around the affected area, responders can control access and minimize the potential for contamination. This step is essential for ensuring safety, as it limits the spread of hazardous substances and provides a designated zone for response operations.

In practice, isolating the area involves assessing the immediate surroundings and determining safe distances based on the material involved, potential consequences, and environmental factors. It lays the groundwork for subsequent actions, such as communication, engagement, and deployment of resources, all while prioritizing the safety of individuals and minimizing risks associated with the incident.
