What is Chief’s Regulation 4?
Chief’s Regulation 4 (Reg 4) is a critical fire safety mandate enforced by the Los Angeles Fire Department (LAFD). It requires property owners, facility managers, and contractors to ensure that fire protection systems are tested regularly by certified professionals. This regulation covers a wide range of equipment, from fire alarms and sprinklers to emergency generators and pressurized stairshafts. Compliance with Reg 4 not only enhances safety but also avoids costly penalties and ensures legal adherence.
Why Reg 4 Matters for Los Angeles Properties
Los Angeles faces unique fire risks due to its dense urban environment, high-rise buildings, and wildfire-prone outskirts. Reg 4 ensures that fire protection systems function optimally during emergencies. Non-compliance can lead to fines, operational shutdowns, or increased liability in case of fire-related incidents.
