When you determine a switch or derail is defective, what must you do?

• A. Not operate the device
• B. Operate it cautiously
• C. Notify a supervisor
• D. Reroute the movement

Answer: (A)

When you find a switch or derail is defective, the immediate priority is to stop using it. A faulty device can move or lock up unpredictably, creating a real risk of a derailment, collision, or injury. Not operating the device eliminates that risk and keeps the track section in a safe state until maintenance can inspect and repair it. After ensuring you do not operate it, you should notify a supervisor and follow safety procedures to tag and secure the equipment so others won’t use it until it’s fixed. Other options aren’t correct because they still involve some use or assumption of safety under conditions that aren’t guaranteed with a defective device.
