Distinguish ASSE 6020 Medical Gas Inspector from ASSE 6030 Medical Gas Verifier roles on a project

Steps

1. Confirm ASSE Standard #6020 (Medical Gas Systems Inspectors) applies to the individual who inspects the installation of medical gas/vacuum distribution piping — typically observing during construction, before concealment, checking labeling and witnessing the installer's initial pressure/leak tests
2. Confirm ASSE Standard #6030 (Medical Gas Systems Verifiers) applies to the individual who performs final testing and verification of the completed, operational system (the full NFPA 99 test battery) before it is placed into service
3. Note that a 6020 Inspector or 6030 Verifier is required to perform the pre-concealment system inspection, and a 6030 Verifier performs the final acceptance verification and issues the verification report
4. Confirm with the project's specifications or AHJ which credential (or both) is required at each project milestone, since some jurisdictions/specs call for an inspector at rough-in and a separate verifier at final
5. Verify that whichever role is used, the individual is independent of the installing contractor — this independence requirement applies to both 6020 inspection and especially 6030 final verification
