In the event of a hazardous materials incident, what should first responders focus on securing?

First responders should prioritize securing the area immediately surrounding the incident in the event of a hazardous materials incident. This focus is crucial to ensure the safety of both the responders and the public. By establishing a perimeter around the hazardous materials, responders can minimize exposure to potential contaminants and prevent bystanders from entering dangerous zones. This perimeter also aids in controlling access for emergency services and allows for a coordinated response to the incident.

The other options do not address the immediate safety and containment needs specific to a hazardous materials situation. Securing a gas station or public transport routes may not be necessary and could distract from the primary objective of managing the incident itself. Concentrating solely on the command center would ignore the critical need for physical safety measures around the hazardous materials, potentially putting more lives at risk. Therefore, focusing on securing the immediate area is the most effective and responsible approach.
