NFPA-99 Practice Exam

Which assembly must be present on-site for the installation of medical gas systems by non-certified personnel?

1. Owner's representative

2. Non-certified helpers

3. Inspector certified to ASSE 6020

4. General contractors

The correct answer is: Inspector certified to ASSE 6020

The presence of an inspector certified to ASSE 6020 is crucial during the installation of medical gas systems by non-certified personnel. ASSE 6020 certification specifically qualifies individuals to ensure that installations comply with established safety standards and regulations. This certification demonstrates the individual's knowledge and understanding of the technical aspects of medical gas installations, which is essential for maintaining the integrity and safety of the systems being installed. Medical gas systems are subject to stringent regulations because they involve gases that are critical for patient care, such as oxygen or nitrous oxide. The inspector's role is to oversee the work done by non-certified personnel, ensuring that all installation practices adhere to the relevant codes and standards outlined by authorities such as the NFPA. While other individuals or groups, such as an owner's representative, non-certified helpers, or general contractors, may be involved in the process, they do not possess the specialized training or credentials necessary to perform the oversight required by the NFPA and ASSE standards. Involving a certified inspector helps to validate that the systems are being installed properly and safely, thereby reducing potential risks associated with non-compliance.
