Is NFPA 99 law?
Well yes and no. NFPA 99 standards are recommendations for minimum requirements of product construction, installation and testing of medical gas systems. There is not a federal law that mandates compliance; however, individual states or local jurisdictions may adopt all or parts of NFPA 99. If this is the case, then the parts of NFPA 99 that the states or local jurisdictions have adopted must be adhered to.
