NFPA-99 Practice Exam 2026 – The All-in-One Guide to Exam Success!

The prohibition against installing medical gas central supply systems in outdoor locations stems from safety and regulatory considerations outlined in various standards, including NFPA-99. Medical gas systems must be installed in controlled environments to ensure a stable atmosphere that maintains the integrity of the gases being supplied. Outdoor locations expose these systems to environmental factors such as temperature fluctuations, moisture, and potential physical damage, all of which could compromise the safety and reliability of the gas supply.

Moreover, outdoor installations might lead to difficulties in monitoring the system for potential leaks or malfunctions, which is critical for ensuring the safety of patients and staff within healthcare facilities. Overall, the requirement for medical gas supply systems to be located in secure, controlled indoor environments reflects a commitment to maintaining a high standard of safety in medical settings.
