Issues regarding the layout of the control room
Thread Content
For a project I was working on recently, the fire hazard classification of the plant building is Class D. Initially, it was planned to locate the plant control room on the second floor of the production building, as a separate fire compartment； However, the safety pre-assessment experts requested that the control room be moved out and made into a separate building. Given the cleanliness requirements inside the project’s factory building, having the control room outside would mean that personnel would need to change clothes frequently when entering and leaving, which is quite troublesome. I searched through all the standards but couldn’t find any requirements regarding control rooms in buildings of Class D and E. I’m asking whether there are any standards or regulations that stipulate that control rooms must not be located in the same building as those with a fire hazard of Class D or E!
There is no such requirement. The Code for Fire Protection Design of Buildings stipulates that offices, rest rooms, etc. should not be located within factories of Class A or B. If it is necessary for them to be adjacent to such factories, their fire resistance rating must be at least Grade 2; they should also be separated from the factories by explosion-proof walls with a fire resistance limit of no less than 3.00 hours, and independent safety exits must be provided； When offices and rest rooms are located within a Class C factory building, they shall be separated from other areas by fire partitions with a fire resistance rating of not less than 2.50 hours and floors with a fire resistance rating of 1.00 hour, and there shall be one separate safety exit provided. There are no specific requirements for Class D and E factories within the plant, but there are requirements for Class D warehouses. In Class C and D warehouses, offices and rest areas shall be separated from other areas by fire-resistant partitions with a thickness of 2.50 hours and floors with a thickness of 1.00 hour, and shall be equipped with separate safety exits. Both factory buildings and warehouses are suitable in themselves, but certain requirements must first be met. However, I have really never seen a control room located on the second floor; it’s the first time I’ve heard of such a thing.
According to Article 8.1.7 of 50016-2014, buildings (complexes) that are equipped with automatic fire alarm systems and fire-fighting equipment that requires interlocked control must have a fire control room. The installation of fire control rooms shall comply with the following requirements: 1. For fire control rooms built separately, their fire resistance rating shall not be lower than grade II ； 2 The fire control room located within a building should be situated on the ground floor or the first basement floor of the building, and preferably in a location near the exterior wall ； 3 should not be installed in rooms with strong electromagnetic field interference or other factors that may affect the proper operation of fire control equipment ； 4 Evacuation doors should lead directly to the outside or a safe exit ； 5 The equipment composition in the fire control room, its functions for controlling and displaying the building’s fire protection systems, as well as its ability to transmit relevant information to remote monitoring systems, shall comply with the provisions of the current standards **\"Code for Design of Automatic Fire Alarm Systems\" GB 50116 and \"General Technical Requirements for Fire Control Rooms\" GB 25506.
From the perspective of building codes, it cannot be constructed on the second floor; if it’s built on the first floor, then it’s necessary to check whether it meets other requirements
