The fire resistance rating of other types of production and living buildings shall not be lower than level 2. 2.0.3 When the steel structure is used in the spray paint warehouse, paint railway lines can be exempted from the restriction of clause 3.1.1, 3.1.2, 3.1.3 of this code, but the fire separation distance between the barreled category B diesel warehouse, the category B and C liquid storage tanks and the railway line shall comply with the relevant provisions of the national standards. 3.1.5 The buildings and structures installed under or adjacent to the railway viaduct shall adopt non-combustible walls with a fire resistance rating of not less than 2.00 h, non-combustible roof panels with a fire resistance rating of not less than 1.50 h, as well as category C fireproof doors and windows. 3.1.6 No greasy plants shall be planted in the railway land boundary. 3.1.7 When the railway passes through the forest area, the width of the fire isolation belt from the center line of the railway line closest to the forest to the edge of the vertical projection of the forest shall not be less than 30 m. 3.1.8 When the railway passes through the fire prevention zone of key grassland, it shall set a fire isolation belt of not less than 20 m from the railway land boundary to the edge of grassland. 3.1.9 When the pipelines for transporting category A, B, C liquids and combustible gas pipelines are buried parallel to the railway, the distance from the crude oil and finished oil pipeline to the railway line shall be not less than 25 m; the liquefied petroleum gas pipeline shall be no less than 50 m away from the railway line, the distance from the railway land boundary shall be greater than 3.0 m, meanwhile it shall comply with the provisions on railway safety protection zone in the "Railway safety management regulations". The fire separation distance between the category B and category C liquid and low-pressure combustible gas pipelines directly serving railway transportation and the adjacent railway line shall not be less than 5.0 m. The fire separation distance between the pipeline of medium-pressure and sub-high pressure inflammable gas and the slope foot of the adjacent railway embankment shall not be less than 5.0 m; however, it can be appropriately reduced after effective safety protection measures are taken under difficult conditions. 3.1.10 The fire separation distance between buried pipelines for transporting category A, B, C liquids and combustible gas pipelines and railway houses shall comply with the provisions of relevant national standards "Design code for gas transmission pipeline engineering" GB 50251, "Code for design of oil transportation pipeline engineering" GB 50253, "Code for design of city gas engineering" GB 50028. 3.2 Locomotive and vehicle facilities 3.2.1 The tank washing line shall be of flat slope end type; the safety distance 4 Combustible liquid and combustible gas pipelines crossing the railway 4.1 Pipeline crossing the line 4.1.1 The pipeline shall not cross intercity railways, railways with a design speed of 200 km/h and above, railways for EMU. The pipeline should not cross over other railways. However, if the crossing is necessary, it shall take safe and reliable protective measures and meet the following requirements: 1 The distance from the bottom surface of the pipeline crossing structure to the top surface of the railway track shall not be less than 12.5 m; the distance from the live part of contact network shall not be less than 4.0 m; the fire resistance rating of the supporting structure shall be level 1. 2 The wall thickness of the crossing segment of the pipeline shall comply with the requirements of "Code for design of oil and gas transportation pipeline aerial crossing engineering" GB 50459. 3 The span shall not be less than the land boundary of the railway. Pipe parts such as flanges and valves shall not be installed in the range of span. 4.1.2 The position where the pipeline crosses the railway shall meet the following requirements: 1 The pipeline should be selected to cross through existing facilities such as railway bridges, reserved pipeline culverts, etc. 2 The pipeline shall not cross the subgrade segment of the ballast-less track of the existing railway. The crossing under special conditions shall be specially designed and shall comply with the limit criteria for the settlement of the subgrade. 3 The pipeline should not be crossed at the base segment of the ballasted track road where the design speed is 200 km/h and above and the track of the EMU, various transition segments, the segments where the railway bridge crosses the main river course of the river. 4.1.3 The crossing angle between the category A, B, C liquid and combustible gas pipelines and the railway shall meet the following requirements: 1 The crossing of pipelines and railways should adopt vertical crossing or large-angle oblique crossing; the crossing angle should not be less than 30°. shall be provided on both sides of the marshalling yard. The fire lanes of the marshalling yard shall be connected to each other. Fire lanes shall be provided on the side of the departure yard of marshalling yard of regional and above marshalling stations. The fire lane should be set close to the parking lot; the distance from adjacent lines should not be greater than 25 m. The fire lane of the marshalling yard can be exempted from providing a turnaround yard. 5.0.3 For the cargo yard with flammable and explosive dangerous goods, the combustible material stock yard and a liquefied petroleum gas tank area with an area of more than 30000 m2, the category A, B, C liquid storage tank area, between the circular fire lanes in the combustible gas storage tank area, it shall set up an intermediate fire lane connected to the circular fire lane. The distance between the fire lanes shall not be greater than 150 m; meanwhile it shall comply with the relevant provisions of the "Code of design on building fire protection and prevention" GB 50016.
