What should you never do when a line set is in motion?

• A. Stay at least 10 feet away.
• B. Call out to the operator.
• C. Check for any visible damage.
• D. Never stand or walk under it.

Answer: (D)

Never stand or walk under a line set when it’s in motion. The moving system can swing, drop a load, or shed components without warning, and the momentum and gravity involved mean you can be struck or entangled even if you’re not directly beneath it at the start. The safest approach is to stay clear and wait for the motion to stop and the system to be secured before approaching. Adding distance or alerting the operator are good safety practices, but they do not eliminate the underlying risk of being under a moving line set. Inspecting for damage or attempting to assess conditions while it’s moving is unsafe; only enter or inspect once it’s stationary and secured.
