What action is described as being necessary after locating leaks during a door fan test leakage assessment?

• A. Seal the leaks
• B. Replace the enclosure
• C. Ignore the issue
• D. Repaint

Answer: (A)

When a door fan test leakage assessment finds leaks, the action taken should be to seal the leaks. The test measures how much air escapes past the enclosure, so the next step is to repair the seal so the enclosure can meet the required airtightness or pressure criteria. This often involves applying appropriate sealants, reinstalling or replacing gaskets or door sweeps, tightening frames, or adjusting hinges to ensure a proper seal. After sealing, the test is repeated to verify that the leakage rate is within specification. Replacing the entire enclosure is only considered if leaks cannot be remedied by sealing, and ignoring or repainting does not address the leakage issue.
