Who performs the verifier's piping purge test?

• A. Installer
• B. Verifier
• C. Quality Assurance
• D. Engineer

Answer: (B)

The verifier performs the piping purge test because their role is to verify that the purge procedure was carried out correctly and that the system is safe for the next steps. This test is about confirming compliance and documenting that no flammable gases or vapors remain before activities like welding or commissioning. The verifier observes, records the results, and determines whether the system passes or needs rework, providing an independent check of the work done. The installer may execute the purge according to procedure, but the actual testing and verification of purge readiness rests with the verifier. Quality Assurance oversees the process and ensures standards are met, while the engineer focuses on design and specifications rather than performing the field test.
