Playbook
Before Touching Grease Duct
Use before cutting, welding, wrapping, accessing, sealing, or modifying kitchen exhaust/grease duct.
What this covers
You are working on kitchen exhaust, grease duct, hood exhaust, welded duct, fire wrap, cleanouts, or access doors.
How to use this playbook
- Treat grease duct as red-zone work. Identify, document, and ask before modifying.
- Confirm it is grease/kitchen exhaust or another high-risk exhaust system.
- Check approved detail for material, joint type, slope, access doors, welding/wrap, and clearance.
- Identify access/cleanout requirements before anything gets covered.
- Check whether hot work permit/fire watch is required for cutting/welding/grinding.
- Take photos of route, joints, access, labels, and conflicts.
- Ask the foreman before cutting, welding, wrapping, moving, or sealing.
Check
- Duct label/system
- Joint/access detail
- Conflict/access issue
- Approved detail if available
Warnings
- Do not treat grease duct like normal exhaust duct.
- Do not bury cleanout/access.
- Do not cut/weld/grind without hot-work control and approval.
- Do not guess on fire wrap, clearance, weld, slope, or access details.
Stop and ask
- Always ask when grease duct work involves access, welds, wrap, slope, penetrations, offsets, clearances, or coordination conflicts.
