Which regulatory body provides standards for medical gas systems safety?

The correct choice is NFPA, which stands for the National Fire Protection Association. This organization develops codes and standards for various safety and fire prevention measures, including the safe installation and use of medical gas systems. The NFPA standards, specifically NFPA 99, set forth requirements that address the safety of electrical, medical gas, and vacuum systems in healthcare facilities. These standards help ensure that medical gas systems are designed, installed, and maintained properly to minimize risks such as leaks and fires, thereby protecting patients and healthcare workers.

Other regulatory bodies, while important in their own domains, do not specifically focus on the safety standards for medical gas systems. The FDA regulates medical devices and substances, OSHA sets workplace safety standards, and the EPA oversees environmental regulations. However, it is the NFPA that specifically addresses the unique safety considerations associated with medical gas systems in healthcare settings.
