What do I do when duct support hardware shows rust, pitting, staining, or corrosion?

Seismic Bracing, Sway Control & Structural CoordinationHigh-risk field starter — overhead support corrosion

Corrosion, pitting, staining, missing tags, or questionable overhead support hardware is a stop-and-report condition — especially in corrosive areas like pools/natatoriums.

Open in Field Rescue Open category

Field checklist

Do not disturb the support if it may be compromised.
Take wide and close photos of rust/pitting/staining, missing tags, and the supported load.
Keep people/work out from under the condition if directed by site safety/foreman.
Ask whether the material, coating, or replacement hardware must be verified for the environment.

Ask foreman

This overhead support/brace has corrosion/pitting and the tag is missing at [location]. Do you want this held for safety/engineering verification before we work under it?

Do not

Do not cover, paint over, wipe away, or replace corroded overhead support hardware without direction.

Why it matters

Corrosive environments can quietly weaken support hardware. Overhead support defects are safety problems before they are craftsmanship problems.
