What should you do before starting work on an inoperable freight door?

1. Check the fuse box

2. Call a supervisor

3. Check the hinges

4. Block open the door and LOTO

The correct answer is: Block open the door and LOTO

Before starting work on an inoperable freight door, it is crucial to block the door open and implement Lockout/Tagout (LOTO) procedures. This ensures that the door cannot be inadvertently closed or operated while you are working on it, which is essential for your safety and the safety of others in the vicinity. LOTO is a safety protocol that protects workers from unexpected energization or movement of machinery, and in the context of a freight door, it prevents anyone from accidentally activating the door mechanism. Other options, while they may seem relevant, do not directly ensure safety while working on the door. Checking the fuse box or the hinges could provide information about the door's inoperability, but they do not address the immediate need to secure the work environment. Calling a supervisor could be part of the process, especially if there are safety concerns or specific procedures that need to be followed, but it does not substitute the need to properly secure the door before work begins. Thus, prioritizing safety through LOTO and blocking the door open is the most appropriate action before starting any repairs.
