What should be verified before performing any maintenance on an elevator?

Before performing any maintenance on an elevator, it is essential to verify lock-out procedures. Lock-out procedures are critical for ensuring the safety of the maintenance personnel and anyone nearby. These procedures involve de-energizing the elevator system and securing it to prevent accidental operation while maintenance work is being conducted. Properly locking out the equipment ensures that no power can be inadvertently restored, which protects workers from potential hazards such as unexpected movements or malfunctions while they are servicing the elevator.

In contrast, while verifying the weight capacity, service history, and emergency procedures are important for the overall safety and functionality of the elevator, they do not directly address the immediate safety concerns that arise during maintenance activities. Lock-out procedures are specifically designed to prevent danger in these situations, making them a priority before any maintenance work begins.
