Static field route #311

What do I do when not sealing screw holes or unused holes?

Sealing, Leakage, Mastic & Pressure Testing.1 field-polished — seal/test detail check

Treat wrong screw holes and unused penetrations as possible leak paths. Mark it and ask how the foreman wants it patched/sealed.

Field checklist

Stop making more holes.
Leave the screw/condition visible until someone verifies it unless directed otherwise.
Mark or photograph the hole location.
Ask whether to seal, patch, or replace.
Use only the approved repair method.

I put a screw hole in the duct face here. Do you want it sealed, patched, or left for inspection before repair?

Do not hide an accidental hole without telling the foreman.

Small holes can still leak, whistle, fail inspection, or create accountability problems later.
