NEIEP Mechanics Practice Exam

What precaution should you take before entering the step/treadway band of an escalator or moving walk?

1. Wear safety glasses and gloves

2. Lock out and tagout the mainline disconnect

3. Check the surroundings for hazards

4. Ensure the escalator is running smoothly

The correct answer is: Lock out and tagout the mainline disconnect

Locking out and tagging out the mainline disconnect is a crucial safety precaution before entering the step/treadway band of an escalator or moving walk. This procedure ensures that the power to the escalator or moving walk is completely turned off and cannot be accidentally turned back on while someone is working in the immediate area. The practice prevents any unintended activation, which could lead to severe injuries. Following this precaution allows personnel to perform necessary inspections, repairs, or maintenance without the risk of being harmed by the moving parts of the escalator or walk. It's part of a comprehensive safety protocol aimed at protecting workers from hazards associated with moving machinery. While checking the surroundings for hazards and ensuring the escalator is running smoothly are important safety behaviors in general, they do not specifically prevent the risk of accidental startup. Similarly, wearing safety glasses and gloves may protect against physical injuries, but they do not address the critical issue of controlling the machine's power source, which is paramount when entering high-risk areas like the step/treadway band.
