Which section of the ERG would you consult for initial isolation distances related to a suspected toxic material?

The correct section to consult for initial isolation distances related to a suspected toxic material is the green section of the Emergency Response Guidebook (ERG). This section is specifically designed to provide guidance on evacuation and isolation distances when dealing with hazardous materials.

The green section focuses on toxic and hazardous materials, giving responders critical information to help determine safe distances to protect the public and emergency personnel from exposure to toxic agents. This information is crucial during an incident to minimize risk and ensure effective response efforts.

Utilizing the green section ensures that responders have access to that vital data necessary for making informed decisions around evacuations and the management of hazardous situations, thereby enhancing safety during the initial phases of an emergency response.
