Understanding Regulation 4 Testing
Regulation 4 inspection refers to the mandatory inspection and testing of fire-life-safety systems in buildings, as outlined by the Los Angeles Fire Department (LAFD). The goal is to ensure these systems function optimally and protect occupants and property during a fire emergency. A comprehensive Reg 4 visit typically includes functional testing of fire alarm panels and devices, sprinkler systems and valves, standpipes, fire pumps, emergency/egress lighting, and other required components. You’ll receive clear documentation of results, plus a list of any deficiencies that must be corrected to maintain compliance and avoid violations or costly downtime.
