Verify before making a permanent change: missing PPE for overhead drilling/cutting.
High-risk starter answer - stop before cutting, drilling, coring, sleeving, enlarging, patching, or relocating any opening. Anchor drilling needs an approved substrate and location, not just a spot that feels convenient.
Ask when the cut affects structure, roof, rated wall, damper/access, grease/industrial duct, equipment, or another trade.
Watch out
Do not cut because the duct does not fit.
Check
Confirm the exact location from approved drawings and field marks.
Check what is above, below, behind, or inside the cut.
Verify whether the wall/deck/roof/shaft/beam is structural, rated, waterproofed, post-tensioned, or shared with other trades.
Verify substrate, edge distance/clearance by approved detail, embed/insert location, and other trade conflicts before drilling.
Steps
Confirm what you are cutting/drilling/fabricating.
Check latest drawing/shop detail.
Look for hidden utilities, structure, rated assemblies, roof membrane, or equipment parts.
Focus on the actual issue: missing PPE for overhead drilling/cutting.
Photograph or mark the condition if someone else needs to approve it.
