Which crew member must have an Emergency Response Guidebook accessible on duty when hazmat is being transported?

• A. Engineer
• B. Dispatcher
• C. Conductor
• D. Passenger

Answer: (C)

In hazmat transport, having quick access to the Emergency Response Guidebook (ERG) is essential for giving first responders accurate material information and initial safety steps. The conductor is the crew member responsible for train safety and coordinating with responders on scene, so they must have the ERG readily accessible on duty. With the ERG, the conductor can identify the hazardous material from placards or shipping papers, communicate the key details to responders, and guide initial actions such as isolation distances, protective measures, and recommended procedures, until specialized help arrives. The engineer’s primary focus is operating the train, and dispatchers aren’t on the train, while passengers aren’t involved in hazmat response.
