I have a question regarding fire separation distances in detailed specifications

This post was last edited by ice2008 on 2024-7-24 at 11:00. Dear experts, I would like to ask about the fire separation requirements in the detailed regulations: 1. In the on-site cabinet room (not for the entire plant, but only for a specific area, serving two or three workshops), if it’s difficult to meet the requirements specified in 4.2.9 regarding the overall plant layout, is it acceptable to classify it as belonging to the “air compressor station, refrigeration station, and 20KV and below power distribution stations”? -Because the stripes indicate the control room; the office building does not include the on-site cabinet room ； 2. Is the distance between Class A flexi-pipes and Class C warehouses appropriate, considering the distance required between Class C warehouses and Class A production facilities? After all, the provisions regarding production facilities do not include storage, transportation, and warehouses. 3, 4.2.9 Note 9: \"The fire separation distances between warehouses or storage areas for Class A, B, and C items, as well as between warehouses or storage areas of Class B and C and other building facilities, shall be in accordance with the building codes.\" Does \"other building facilities\" refer specifically to buildings or does it also include production facilities? 4. What is the distance between the loading/unloading hose of Class C vehicles and Class C storage tanks? Is it to connect a Class C loading/unloading hose to the production facility at a distance of 10 meters, in accordance with note 7 of 4.2.9?
1. In the on-site cabinet room, the number of technical or control devices that provide services for a specific area is generally not considered part of the plant-wide facilities such as air compressor stations, refrigeration stations, and power distribution rooms. In the classification and division of fire separation distances according to the detailed regulations, the on-site cabinet room is more similar in nature to a control room, although it is not exactly equivalent to a conventional control room or office building. The fire separation requirements for control rooms or similar functional areas should be referred to. 2. Regarding the distance requirement between Class A flexible hoses and Class C warehouses, according to fire safety regulations, it is generally required that the fire separation distance comply with that of the higher hazard category (in this case, Class A production facilities). Therefore, it is appropriate to apply the distance requirement for Class A flexible hoses to Class C warehouses based on the distance from Class C warehouses to Class A production facilities, which is in line with the principle of safety management using a strategy tailored to higher risk levels. 3. “Other building facilities”, as described in Note 9, generally refer to other types of buildings or facilities other than those main buildings or facilities that are explicitly listed. This may include both some auxiliary buildings and specific production facilities. The specific determination should be based on the specific functions of these facilities and their role in the process flow, rather than just their physical form. When applying the specifications, it is necessary to analyze each situation on its own to ensure that the standards for safe distances are properly implemented, thereby safeguarding the fire safety of the entire area. .
