Let’s take a look at which standard and which article this passage comes from ? ? ? Guess! ! As stated below: When arranging the equipment, necessary passages and areas should be considered comprehensively based on the requirements for construction, maintenance, operation, and fire safety. Inside the facility, application roads divide it into equipment and building areas with a floor area not exceeding 10,000 m2. When the floor area of the esterification polymerization, spinning, and post-processing facilities for synthetic fiber production exceeds 10,000 m2, passageways should be installed on both sides of them. The main traffic passage within the facility should be connected to the factory roads. (l) The installation of fire access routes shall meet the following requirements: l) When the width of the installation exceeds 60m, a continuous fire access route shall be provided within the installation ； 2) When the device width is 60m or less and there are fire access routes on both sides of the device, a through fire access route is not required. Non-through roads within the facility should be provided with turnaround areas. 3) The width of the road should not be less than 4m; the clear distance between the pipe rack on the road shoulder and the edge of the road surface should not be less than 1m. The internal turning radius of the road surface should not be less than 7m, and the clear height above the road surface should not be less than 4.5m. (2) The maintenance access path shall meet the requirements of mechanical maintenance equipment regarding road width, turning radius, and load capacity, and shall lead to the lifting holes for equipment maintenance. (3) The main vehicle passages, fire escape routes, and maintenance passages within the facility should be arranged together. (4) The operation passageways should be determined based on the frequency of production operations, routine inspections, minor repairs, etc., as well as the distribution of the operation points. (5) The minimum width and minimum clear height of the passages within the device are specified in Table 5.1.47. Minimum width and minimum clear height of passages within the facility
Passage name Minimum width/m Minimum clear height/m Passage name Minimum width/m Minimum clear height/m Fire exit passage 4.0① 4.5① Maintenance passage under the pipe gallery for pumps 2.0 (3.0) 3.0 (3.3) Main vehicle passage 4.0 (6.0)② 4.5 (5.0)② Operation passage 0.8 2.2 Secondary vehicle passage 3.0 (3.5) 3.0 (4.5) Note: ① For facilities where large equipment may pass through, the requirements for the clear width and clear height of the main vehicle passages are as specified in Table 5.1.47. ②The values in parentheses in the table are specified by the chemical industry standards.
