Look for overhead install, rigging, lifts, and loose material.
Stay outside barricades or marked zones.
Make eye contact with the crew overhead before entering.
Announce yourself if you must pass nearby.
Use another path when possible.
Ask foreman
Is this area controlled, or should I route around while overhead work is active?
Do not
Do not walk under duct being lifted, aligned, fastened, or adjusted.
Why it matters
Dropped tools, fittings, and duct sections turn a normal walkway into a strike zone.
