Temporary Barriers or Negative-Air Equipment Block the Installation Route
Re-plan the material path and work sequence with the containment owner before moving, cutting, or opening barriers. Temporary walls, negative-air machines, hoses, filters, and protected paths may be part of the occupied-space control plan and cannot be moved casually.
The approved duct path is blocked by the temporary containment and negative-air setup. I checked the alternate route and the section will not turn through it. Can we coordinate a controlled barrier opening or revised installation sequence with the containment owner?
Watch out
Do not unplug, relocate, cut, or prop open containment equipment to get duct through.
Check
Identify who owns the barrier and what area it protects.
Check alternate material paths, piece lengths, lift access, and work windows.
Verify whether opening the barrier changes pressure, cleanliness, egress, or store operations.
Document any required temporary removal and restoration.
