Fan connection/flex connector requirements not verified

Treat grease/special exhaust as red-zone work: not verifying fan connection/flex connector requirements.

High-risk starter answer - treat grease duct, hood exhaust, kitchen exhaust, lab exhaust, and special exhaust as red-zone work. Hood/fan/equipment connections affect access, vibration, drainage, cleaning, and inspection.

Stop if

• Ask any time grease/special exhaust involves access, weld, wrap, slope, clearance, penetration, contaminant, or support questions.

Watch out

• Do not assume normal galvanized duct rules apply.

Check

• Confirm whether this is grease duct, kitchen exhaust, lab exhaust, industrial exhaust, or normal exhaust.
• Check the approved drawings/spec/submittal.
• Look for cleanout/access, clearance, enclosure/wrap, weld/seal, slope/drainage, and inspection requirements.
• Verify equipment tag, connection detail, service access, and cleaning access before fastening.

Steps

• Confirm the system is grease, kitchen exhaust, industrial exhaust, dust, or chemical/fume exhaust.
• Check approved detail for material, access, cleanouts, joints, wrap, slope, and support.
• Identify hot-work or fire-watch requirements.
• Focus on the actual issue: not verifying fan connection/flex connector requirements.
• Photograph or mark the condition if someone else needs to approve it.
