Facility Classification
NFPA 99 (Health Care Facilities Code) classifies healthcare facilities into three levels based on the risk of patient harm if a medical gas system fails:
- Level 1: Facilities where interruption of medical gas or vacuum service would likely cause patient death. Examples: surgical suites, intensive care units (ICUs), cardiac catheterization labs, emergency departments, neonatal ICUs (NICUs). Requires the highest redundancy, source equipment reliability, and alarm coverage.
- Level 2: Facilities where interruption of service may cause patient harm but is unlikely to cause death. Examples: general medical/surgical floors, birthing rooms, some endoscopy suites.
- Level 3: Facilities where interruption of service is unlikely to cause patient harm. Examples: physician offices, dental offices with nitrous oxide, clinics.
