During overhaul, if an overhead door is open, what is the recommended temporary measure?

• A. Place locking pliers on it
• B. Notify supervisor and close the door manually
• C. Use a wedge to prop the door
• D. Stand clear and monitor from a distance

Answer: (A)

If an overhead door is left open during overhaul, you want a quick, reliable way to keep it from moving unexpectedly. Placing locking pliers on the door provides a firm temporary restraint that prevents the door from closing or shifting while work is underway, and they can be released quickly when the door needs to move again. Using a wedge can slip or fail under load and wind, and standing back or waiting for supervision delays securing the door, so locking pliers give direct, controllable protection in this situation.
