UL 181-rated material where required not used

If UL 181/listed material is required, wrong tape is a stop-and-verify issue. Do not leave standard cloth duct tape on a specified system.

Stop if

This looks like non-approved tape where UL 181/listed material may be required. Do you want it corrected before test/cover?

Watch out

Do not assume silver tape is acceptable because it stuck to the duct.

Check

Check the tape/sealant label.
Verify project spec/manufacturer requirement.
Mark the affected section.
Ask before removing/replacing wrong material.
Repair with approved material and document before test/cover.
