This regulation requires that building systems in healthcare facilities be designed to meet Category 1 through 4 requirements as defined in NFPA 99, with categories determined through a formal, documented risk assessment conducted by qualified personnel. It is a life-safety/engineering standard governing physical plant infrastructure rather than a behavioral health, IDD, ABA, or foster care licensing rule.
