Gas Line Certification

Requires annual certification and re-certification any time system is breached. (NFPA 99C)

JCAHO Follows NFPA requirements.


The intent of a Gas Line Certification study is to document, evaluate and make appropriate recommendations in order that the hospital will be in compliance with the National Fire Protection Association's guidelines on medical gas and vacuum systems as outlined in their publication ANSI/NFPA 99C: "Gas and Vacuum Systems".

EMT's Gas Line Certification Program Includes:

  • Outlet/Inlet inspection for flow, particulate, cross conection, proper seating, leaks, color code, ratio of terminals to beds, and location

  • Testing of all O2 outlets to confirm O2

  • Testing of all Medical Air outlets for O2

  • Testing of all N2O outlets

  • Inpection of all Primary and Local gages

  • Ultrasonic testing of Zone valves and inspection for leaks, labeling, location, and operation
