First, the overall layout of high-rise building

1. the distance with fire station should ensure alarm arrive within 5 minutes.
2. in other civil architecture of distance should maintain the necessary fire separation.
3. the high-rise construction should not be arranged in flammable and explosive buildings nearby, and should maintain sufficient spacing.
4. tall buildings in a general layout requires at least one of its bottom edge of the long side or the length of around 1/4 and not less than one long side length, should not be greater than the layout height, depth greater than 5m 4m's podium, and in this context must be provided through outdoor staircase or through stairwells of export for fire vehicles and firefighters. Fire channel and between high buildings, should not prevent a fire engine layout placement operations of trees, overhead pipeline, etc.
　　
Fuel, gas boiler house, fuel oil, oil-immersed transformer high voltage capacitors and many oil switch yishe in high-rise buildings, private room, the equipment must be located in a building, its total evaporation of the boiler should not exceed 6T/h, and a single boiler and evaporation volume should not exceed 2T/h; fuel oil-immersed transformer should not exceed capacity, single size 1260KVA should not exceed 630KVA and should satisfy the following requirements:
　　
⑴ fuel, gas boiler house, fuel oil, oil-immersed transformer high voltage capacitor and many oil switch, etc should not be located in the personnel-intensive sites on a layer, the next layer or stick-o-and-fire resistance of door and window openings is not lower than the partition and 2h 1.5h of floors and other parts of the body. When you must open the door, you should set a fire door.
　　
⑵ the boiler room, the transformer room on first floor should be laid out in the basement or rely on external sites, and should be set directly outward security exports. On top of the wall opening area, you should set a width of not less than width not burning body fire cornice.
　　
⑶ transformer following should have stored all the transformer oil quantity; accident oil transformer, many oil switch rooms, high-voltage capacitor room should be set to prevent oil dispersed facilities.
　　
5. diesel generator room can be arranged in high-rise buildings, podium first layer or a layer of ground, and should meet the following requirements:
　　
⑴ diesel generator room should be not less than the fire resistance of partition wall and 2h 1.5h of floor space with other parts of the body.
　　
⑵ diesel generator room should have oil, its total capacity should not exceed demand, 8h storage room should be set to open the firewall and generators; when the interval must be open on your firewall, you should set themselves off of a fire door.
　　
6. the audience Hall, conference rooms, function rooms, personnel are crowded places, should be set at the first floor or the second and third level; must be set on other floors, should satisfy the following requirements:
　　
⑴ a Hall, room area is not more than 400 square meters;
　　
⑵ a Hall, room security exports should not be less than two;
　　
⑶ must set the automatic fire alarm systems and automatic sprinkler systems;
　　
⑷ curtains and curtains should be used as flame retardant treatment of fabrics.
　　
7. when the high-rise building in nurseries, kindergartens, should be set in the building's first floor or the second and third level, and to set up separate entrances.
8. the high-rise construction using CPI liquid fuel tank should not exceed 15 cubic meters, when buried in high-rise buildings and podium near the tank side 4m range of exterior to the firewall, its fire separation can be unlimited. Intermediate tank volume should not be greater than 1 m3, and should be located in the fire resistance rating of not less than two separate rooms, the room door should use class a fire door.
　　
9. the high-rise construction in the use of combustible gas as fuel, gas pipelines should be used, the use of combustible gas in the room or area should rely on external settings. When using the liquefied gas as fuel, located centrally between the bottled liquefied petroleum gas (LPG). Its total reserves of not more than 1 cubic meter, can be used with podium with adjacent construction; total reserves of more than 1 cubic meter, and not more than 3 cubic metres, should be independent of the construction of tall buildings and podium of the fire separation should not be less than 10 meters.
　　
10. fire control room yishe in high-rise building of the first floor or basement, and should be not less than the fire resistance of partition wall and 2h 1.5h's floor and separated from other parts of the body, and should be set through outdoor security exports.
　　
2. the General layout of industrial enterprises

Factory and warehouse floor, according to the building's fire risk, topography, the surrounding environment as well as many leading wind, reasonable layout, General should meet the following requirements:
　　
1. the larger factories, warehouses, according to the actual needs, reasonable division production areas, storage areas (including open storage area), production facilities and administration, welfare, etc..
　　
2. the same production company, if there is fire hazard in the fire risk of large and small production building, you should try to fire risk same or similar construction set layout to take fire explosion protection measures for safety management.
　　
3. takes note of the environment. In the choose when the factory, warehouse address, it is necessary to consider the safety of this unit, and to consider the adjacent areas of the safety of the residents of the enterprise. Flammable, explosive factory, warehouse, the application entity to separate the outside walls.
　　
4. the terrain conditions. A, b, c, liquid warehouse layout in low-lying areas, so as to avoid causing fire threat environment; if it must be arranged in higher height, you should take certain fire safety measures (such as stop and retaining all the dispersed liquid fire embankment). Acetylene station water produce combustible gas, fire and explosion of industrial enterprises, is strictly prohibited arrangement in easy-to-be submerged byPlace.
　　
For explosive materials warehouse, should give priority to the use of terrain, such as a select number of sides by mountains, there is no place in the vicinity of the building to reduce the hazard of explosion.
　　
5. takes note of the wind. Dissemination of combustible gases, flammable vapor and combustible dust workshop, appliances, etc., should be laid out in the factory of the year the leading wind direction downwind or side wind.
　　
6. substances exposure can cause a fire, explosion, two buildings or open pit production device separately, and be sufficiently safe distance. Such as oxygen station suction air separation equipment, is located in a outlet of acetylene and carbide slag heap or dissemination of other hydrocarbons in part as a dominant wind direction in the direction of the wind, and that they must not be less than 100 ~ 300 meters distance, such as oxygen process with adsorption purification plant, can be reduced to 50 meters.
　　
7. to address two different units reasonable to stay open, the factory district or area fencing and Manufactory (library), the distance is not appropriate within the building is less than 5 meters, and should meet the walls on either side of the building fire between spacing requirements. Liquid oxygen tank around 5 m should not have fuel and set the bituminous pavement.
　　
8. transformer substation, the distribution should not be located in potentially explosive atmospheres, CPI plant in or adjacent construction. B plants distribution must open the window on the firewall, you should set not burning body seals fixed window.
　　
9. a, b and a, group b substances Treasury should not be located in the building's ground floor or basement.
　　
10. plant in set a, group b substances intermediate warehouse, its reserves should not be more than a day requirement. Intermediate warehouse should rely on the exterior wall decoration, and should be in the fire resistance of not less than 3 hours without burning body wall and 1.5 hour not burning body is separated from other parts of the floor slab.
　　
11. have the explosion of a, b building should not be set in the Office, rest rooms. If you must stick-o-this plant sets should be used first, second grade construction and refractory and should be used in the fire resistance of not less than 3 hours without burning body separated by a firewall and setting through outdoor or staircases security exports.
　　
12. There is a risk of explosion, CPI plant total control room should be set up independently; it is divided into the control room to the adjacent wall settings, and apply the fire resistance rating of not less than 3 hours without burning body wall and is separated from the rest.
　　
13. have the explosion of a, b production sector, the single-story building near yishe wall or multilayer plant of most previous layer depends on the exterior wall. Potentially explosive atmospheres of devices should, as far as possible, avoid the powerhouse of beams and columns, load bearing members.
