Readiness check

Will your fireproofing actually hold its fire rating?

Fireproofing fails silently. The steel looks covered, but if the thickness is short, the bond is bad, or the damage was never patched, the fire rating is gone and nobody knows until the fire. Answer for how the work is actually applied and inspected. The score stays on your device; enter an email only if you want the fireproofing readiness checklist sent over.

1. Are you applying to a specific tested, listed assembly (the UL design) for the member and rating?Yes, the listed assembly is identified and followedWe use a product but not a specific designWe just spray it on

2. Is the thickness set from the member's size (W/D ratio) and the listed design, not a guess?Yes, per-member thickness from the designOne thickness for everythingWe eyeball coverage

3. Did you confirm the shop primer is compatible so the fireproofing will bond?Yes, primer compatibility confirmed or bare/bonded steelNot sure what primer is on the steelWe spray over whatever is there

4. Is the steel clean (no oil, loose mill scale) before application?Yes, surface prepped and cleanMostly, not really checkedNo prep

5. Do you verify SFRM density, not just thickness?Yes, density tested to the listingThickness onlyNeither is tested

6. Is there special inspection of thickness, density, and bond (adhesion/cohesion)?Yes, special inspection per the code, documentedOccasional spot checksNo inspection

7. Is fireproofing knocked off by other trades (for duct, pipe, hangers) patched back?Yes, all damage patched to the assemblySome of it, when noticedNo, damage is left as is

8. Do you keep fireproofing (the member) separate from firestop (the penetrations) in scope?Yes, both are scoped and done correctlyWe blur the twoWe are not clear on the difference
