Insulation installed before pressure test

Do not insulate before pressure testing or leakage checks when the job requires testing. Covering early makes leaks harder to find and fix.

Stop if

• Is this section cleared for insulation, or does it need pressure/leakage testing first?

Watch out

• Do not wrap over joints that still need to be tested.

Check

• Confirm whether this system/zone requires pressure or leakage testing.
• Check that all required test sections are visible and accessible.
• Hold insulation until test or foreman release is complete.
• Photograph if cover approval is given.
