Who must have a copy of the Emergency Response Guidebook accessible while on duty when transporting hazmat?

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

Answer: (A)

The key idea is that someone in charge of the hazmat shipment must have immediate access to the Emergency Response Guidebook while on duty. In railroad operations, that person is the Conductor, who is on board, oversees train safety, and is the first line manager for any on-scene actions. Having the ERG handy lets the Conductor quickly identify the specific material, understand its hazards, and determine the initial protective actions, necessary isolation distances, and how to contact the right emergency responders. The engineer is focused on operating the train, the dispatcher coordinates remotely, and passengers aren’t responsible for hazmat response, so they aren’t the person required to carry the ERG.
