Prepare One Duct Section for Leakage Testing

Isolate the exact section, secure every temporary opening, verify the duct is supported, and walk all joints before the test equipment is connected.

Stop if

• Can we walk the test boundaries together before the rig connects so I know every cap, door, damper, and temporary opening is accounted for?

Watch out

• Do not pressurize an undefined section or rely on tape-only caps that can release under pressure.

Check

• Confirm test boundaries and pressure class from the approved test plan
• Cap branches, openings, access doors, and instrument ports as directed
• Secure temporary caps against test pressure
• Verify supports, joints, dampers, and flexible connections are ready
• Remove loose debris and identify who controls pressurization
