One resource that deals with protective action distances involving toxic gas is?

The DOT Emergency Response Guidebook is the correct answer as it is a crucial resource used by first responders in the event of a hazardous materials incident, especially those involving toxic gases. This guidebook provides vital information on how to handle specific toxic substances, including protective action distances, which are essential for ensuring the safety of responders and the public during an emergency situation.

It outlines recommended distances for evacuation and safety measures based on the type of hazardous material involved, allowing firefighters and emergency personnel to make informed decisions quickly. The guide’s focus on immediate response actions aids in minimizing exposure to dangerous gases, highlighting its importance in the context of hazardous material incidents.

In contrast, the Fire Protection Handbook generally covers a broad range of topics regarding fire protection and safety measures but may not have the same level of detail on specific toxic gases and their protective action distances as the DOT Emergency Response Guidebook. The National Fire Code sets standards for fire prevention and safety but does not specifically address toxic gas response guidelines. The Incident Command System Manual primarily outlines the structure and management of incident command rather than detailed guidelines for hazardous materials response.
