Gas fire suppression installation in the cabinet room

First, it is necessary to clarify the fire protection design for the cabinet rooms – is a fire suppression system required? What type of fire suppression system is needed? Explanation of the provisions in GB 50160-2008 (2018 edition): 8.11.3 Control rooms, cabinet rooms, and power distribution stations in petrochemical enterprises have special characteristics compared to ordinary computer rooms; therefore, there is no requirement to install fixed automatic gas fire extinguishing systems. The reasons are as follows: 1. Control rooms in petrochemical plants are staffed 24 hours a day, so in the event of a fire, the on-duty personnel can detect it promptly and extinguish it as soon as possible ； 2 All buildings are equipped with automatic fire alarm systems in accordance with **relevant regulatory requirements; in the event of a fire in areas such as power distribution rooms, cabinet rooms, and cable trays, the fire detection system can promptly alert a 24/7 manned control room, enabling relevant personnel to take action in a timely manner ； 3 Once the fixed gas fire extinguishing system is activated, the on-duty personnel in the control room need to evacuate immediately; otherwise, the system may become dysfunctional due to a lack of supervision, leading to a secondary fire or more serious accidents. 4 This standard sets clear fire protection requirements regarding the building fire protection, layout, and equipment selection for control rooms, cabinet rooms, and power distribution stations, thereby enhancing the inherent safety of these buildings. Since the fires that occur in substations are mainly electrical fires, and water should not be used to extinguish such fires, no fire hydrants are installed in substations for firefighting purposes. "
