Which guide is a resource that deals with protective action distances involving toxic gas?

The correct resource that deals with protective action distances involving toxic gas is the DOT Emergency Response Guide Book. This guide serves as a crucial tool for first responders during hazardous materials incidents, providing vital information on how to respond safely to chemical releases. It includes essential details about protective action distances, which are necessary for ensuring the safety of responders and the public when dealing with toxic gases.

The Emergency Response Guide Book outlines specific actions to take based on the type of hazardous materials involved, including the necessary evacuation distances and recommended protective measures. It is widely used by firefighters, emergency medical personnel, and other responders to assess risks and manage situations involving toxic substances effectively.

In contrast, the other guides mentioned do not primarily focus on protective action distances related to toxic gas. The FEMA Guidelines are more about disaster preparedness and response, the EPA Handbook concentrates on environmental protection and compliance regulations, while the OSHA Manual emphasizes workplace safety standards and regulations. Each of these resources is important in its context, but when it comes specifically to protective actions involving toxic gases, the DOT Emergency Response Guide Book is the definitive resource.
