Which resource specifically addresses protective action distances involving toxic gas?

• A. NFPA 704 standard
• B. DOT Emergency Response Guidebook
• C. OSHA Hazard Communication Standard
• D. EPA Risk Management Plan

Answer: (B)

This question is about which resource gives actionable distances for protective actions when toxic gas is released. The DOT Emergency Response Guidebook is designed for responders in the field and includes specific protective action distances for toxic inhalation hazards. It tells you how far to evacuate or shelter in place based on the material involved, the release scenario, and the level of risk, helping responders make quick, practical decisions to protect the public and themselves. Other resources serve different purposes: NFPA 704 is a hazard identification system used to quickly convey the hazards at a facility, not to provide response distances. OSHA Hazard Communication Standard covers labeling and safety data sheets to inform workers about hazards, not field protective action distances. EPA Risk Management Plan focuses on facility-level planning to prevent and respond to releases, not on immediate action distances during an incident. So the Emergency Response Guidebook is the reference that specifically addresses protective action distances for toxic gas releases.
