Identify whether you are looking at a hanger, brace, restraint, anchor, insert, structural member, rigging gear, or crane/lift-day zone.
Mark the location, take a photo, and ask whether restraint is required at that run, riser, or equipment connection.
Ask foreman
In Seismic Bracing, Sway Control & Structural Coordination, I’m looking at: What do I do when missing brace at duct riser/vertical run? What should I verify before I cut, drill, seal, cover, move, or install?
Do not
Do not modify or copy bracing/rigging from another area just because it looks similar.
Why it matters
OSHA 1926.1425 keeping clear of load; OSHA 1926.1428 signal person qualifications; OSHA 1926.251 rigging equipment; SMACNA/project bracing details where applicable
