If you realize the car immediately next to the locomotive is a loaded tank car with a corrosive placard, are you required to switch the head end of the train for hazmat placement?

• A. Yes
• B. No
• C. Only if directed by a supervisor
• D. Not necessary

Answer: (A)

Hazardous materials require special placement on the train to keep the crew and responders as safe as possible. The rule is that hazmat cars should be in the head end position so the lead end of the train has immediate visibility and control over the hazard while the train is moving.

If you notice a loaded tank car with a corrosive placard right next to the locomotive, that triggers the hazmat placement requirement. You should switch the head end of the train to ensure the hazmat car is positioned as the lead car, ahead of other cars, so the hazard is clearly identified and managed from the front of the train. This setup helps with safe braking, communication, and emergency response.

Waiting for supervision or saying it isn’t necessary would not align with the safety practice of promptly placing hazmat cars at the head end.
