This regulation specifies fire and life safety construction requirements for smoke barriers within building spaces, requiring either a ½-hour (existing buildings) or 1-hour (new buildings) fire resistance rating, with specific provisions for smoke dampers in fully ducted HVAC systems with sprinkler coverage. Facility operators must ensure smoke barriers are constructed per NFPA Life Safety Code standards and document any mechanical smoke control systems in remarks. This is a physical plant/life safety standard applicable to the facility type governed by the broader licensing chapter.
