NFPA-99 Practice Exam

What is typically the responsibility of the medical gas systems installer after completing a new installation?

1. Conduct a hydrostatic test.

2. Verify functionality of alarm systems.

3. Perform an initial pressure test.

4. Check color coding on pipes.

The correct answer is: Perform an initial pressure test.

The responsibility of performing an initial pressure test after completing a new installation of medical gas systems is vital to ensure the safety and integrity of the system. This initial pressure test specifically assesses whether the system can withstand the required pressures without leaking. It is a critical step because any failure to maintain pressure could lead to serious consequences, including the risk of gas leaks, which could endanger patient safety. Additionally, conducting an initial pressure test ensures compliance with relevant codes and standards, such as those outlined in NFPA 99, which is focused on healthcare facilities. This verification helps to confirm that the installation meets all operational requirements before the system is put into service. While verifying the functionality of alarm systems, conducting hydrostatic tests, and checking color coding on pipes are also important elements of ensuring a safe and compliant medical gas system, they typically do not take precedence as the primary responsibility immediately following installation. The initial pressure test serves as a foundational step that precedes other tasks in the overall commissioning and operational readiness of medical gas systems.
