MCC-NH Gas Fitters Practice Exam

During a pressure test, what do you do if the piping is concealed?

1. Examine the exposed components only

2. Cover it completely to prevent leaks

3. Use remote inspection methods

4. Remove the concealment for access

The correct answer is: Remove the concealment for access

In the context of conducting a pressure test on concealed piping, removing the concealment for access is essential in ensuring a thorough and accurate assessment. When piping is concealed, there’s a risk that leaks or issues could go undetected, which could lead to safety hazards or future failures. By removing the concealment, you can directly inspect the piping, verify that it is intact, and confirm that no leaks are present under pressure. This action aligns with industry standards for safety and reliability, as it's critical to have direct access to all components that may fail or show signs of wear. Additionally, surface inspections alone may not reveal hidden problems that could fully compromise the system's integrity. Remote inspection methods, while beneficial in some circumstances, may not provide the same level of assurance as a hands-on examination, making complete accessibility imperative during the pressure testing process.
