How is the width of the factory safety channel determined?
User question: Our company is now renovating the workshop. Is there any regulation in the workshop? Expert reply Zhou Huazhong (Director and Safety Senior Engineer of China Occupational Safety and Health Association): In the new construction, reconstruction and expansion of the factory, the width of the safety passage of the factory must first meet the requirements of the national standard and specification. There are two criteria to be met here : Standard 1. The “Code for Design of Plant and Mine Roads†under the jurisdiction of the Ministry of Communications [2007] Edition] (Standard No. GBJ 22-1987); Standard 2, "Code for Fire Protection of Building Design" (GB50016-2006) edited by the Ministry of Public Security. These two standards have relatively clear provisions on the width of the safety passages and fire lanes and should be implemented. For example, the setting of the fire lane should meet the following requirements: 1 The reserve should be larger than the stack yard and storage tank area specified in Table 6.0.7. 2 The combustible material yard with an area of ​​more than 30,000 m2 should be provided with an intermediate fire lane connected to the circular fire lane. The distance between the fire lanes should not exceed 150.0m. Liquefied petroleum gas storage tank area, liquid storage tank area of ​​Class A, B and C, flammable gas storage tank area, and connected fire fighting lanes should be set between the circular fire fighting lanes in the area. 3 The minimum distance between the fire lane and the material yard stack should not be less than 5.0m. 4 The intersection of the intermediate fire lane and the circular fire lane shall meet the requirements for the turning radius of the fire truck. 5 The net width and headroom of the fire lane should not be less than 4.0m. The slope of the open space for fire trucks should not exceed 3%. Obstructions that impede the operation of fire trucks should not be placed between fire lanes and factory buildings (warehouses) and civil buildings. At least two circular fire lanes should be connected to other lanes. 6 The end of the fire lane should be set back to the lane or return yard, the area of ​​the return yard should not be less than 12.0m × 12.0m; for large fire trucks, should not be less than 18.0m × 18.0m. The fire lane should not be level with the main line of the railway. If it is necessary to level, an alternate lane should be set and the distance between the two lanes should not be less than the length of one train. At the same time, the passages in the factory floor (visiting channels and material handling channels) should also be considered from the perspective of “safe production†and “fixed managementâ€. From the perspective of “safe productionâ€, the safety distance and the working space distance are mainly considered. The requirements for safety distance include the distance between equipment and facilities, such as dumping, high-altitude objects, radioactive elements, heat radiation, cold convection, chemical corrosion, etc., to avoid damage or damage to people and objects. Workspace distance requirements include consideration of reasonable access distances for workpieces, materials, tools, transportation, etc., including the width of the transport vehicle. In the process of factory renovation, we should try our best to learn from the previous work. Due to the disadvantages of some disadvantages in the channel setting in the workshop, we should actively absorb the rationalization suggestions put forward by the technicians, and scientifically and reasonably determine the width and spatial extent of the safety passage. |
