Common Questions

Why are medical gas systems so strictly regulated? Medical gas systems are strictly regulated because they deliver life‑critical gases directly to patients, and any error, contamination, or failure can cause serious injury or death—often affecting many patients at once. Strict rules ensure safety, reliability, and prevention of fires, contamination, or wrong‑gas delivery.

Who can install medical gas systems? Medical gas systems can only be installed by licensed contractors who are specifically trained and certified in medical gas installation, working under NFPA 99 and local code requirements, with the system independently tested and verified by a certified medical gas verifier.

What kind of medical gas systems can we install? Medical gas systems include oxygen, medical air, vacuum, nitrous oxide, nitrogen, carbon dioxide, and waste anesthetic gas systems, all of which safely supply or remove gases used in patient care.

How are medical gas systems different from standard plumbing systems? Medical gas systems are life‑safety systems. Unlike standard plumbing, they require specialized materials, certified installers, brazing procedures, pressure testing, and third‑party verification to ensure patient safety and regulatory compliance.
