NFPA 99 requirements for medical gas system maintenance has always been a gray area. There had been recommendations in appendix C, but they were not actually part of the requirements.
It wasn’t until 2012 that the NFPA 99 actually included maintenance requirements for equipment and for people who perform maintenance. Inventory requirements, inspection schedules, inspection procedures, maintenance schedules, and qualifications of people maintaining these systems are all part of the 2012 edition.
There are three different qualification requirements for people maintaining medical gas systems:
- If your facility staff are maintaining your own medical gas systems they are required to either obtain training through your facility on the specific equipment installed, or by obtaining credentialing to the ASSE 6040 medical gas maintainer.
- Third party companies that provide services to facilities to test and maintain medical gas systems are now required to hold credentials in accordance with the ASSE 6040 medical gas maintainer or 6030 medical gas verifier
If you didn’t already know, CMS has adopted the 2012 edition of the Life Safety Code 101 which references the 2012 NFPA 99. That means these requirements do apply to your facility staff as well as third party testing and maintenance companies.
If your staff is currently maintaining your medical gas systems you need to ask the questions; are they qualified, and do they have a documented procedure? If you have a third party service provider; do they have credentialed service technicians?
