An existing system that is not in strict compliance with the provisions of the code shall be permitted to be continued in use as long as the authority having jurisdiction has determined that such use does not constitute a distinct hazard to life. Who is this authority?

The authority having jurisdiction refers to the official responsible for enforcing the applicable regulations and codes within a specific area or facility. This authority plays a crucial role in assessing existing medical gas systems and determining whether they can continue to be used without posing a safety risk. Their evaluation process ensures that any existing system is safe and does not create a distinct hazard to life, even if it doesn't strictly meet the latest code requirements.

Architects, engineers, and nursing staff may hold important roles in the design, construction, or operation of medical facilities, but they do not have the final say in compliance and safety assessments regarding codes and regulations. Thus, it is the authority having jurisdiction that carries the responsibility of making these crucial determinations.
