Internal liner loose causing obstruction
Loose internal liner is a hidden airflow blockage. Stop before sealing/covering and get direction on repair or replacement.
Watch out
- Do not shove loose liner back and cover it without approval.
Check
- Look inside the duct/opening if safely visible.
- Check whether liner is loose, folded, torn, or blocking the air path.
- Verify whether liner repair/replacement is allowed by project spec.
- Photo the condition before it gets covered.
- Ask before taping, gluing, or trimming liner in the field.
