first section to allow safe evacuation time, the export volume, width and distance of the general requirements

one, to allow safe evacuation Time

allow time for safe evacuation, is the person to leave the building when the fire reached the building fire safety zone time. Allow time for safe evacuation, is to determine the safe evacuation distance, security, channel width, an important basis for security exports. If the building is smoke

staircase, the stairs are not calculated on the evacuation time.

evacuation time allowed, tall buildings, consideration may be 5-7 minutes; general civil construction, primary and secondary fire resistance rating should be 6 minutes, three, four fire resistance rating for 2-4 minutes . Personnel-intensive public buildings,cheap UGG boots, one, two fire resistance rating should be 5 minutes, three fire resistance rating of the building should not exceed 3 minutes in which to evacuate the auditorium of the time, one,UGGs, two fire resistance rating of the building should not exceed 2 minutes, three fire resistance rating should not exceed 1.5 minutes.

Second, the safety distance

sparse with the safety of civil evacuation distance refers to the house from the room door or door to the nearest exit or stairwell outside the maximum distance; plant from the evacuation means plant operating point furthest to the outside within the export or the maximum distance between the stairs.

limited purpose of safe evacuation distance, is to shorten evacuation time, as soon as possible so that people evacuated to safety from the fire scene area.

Third, the width of the building evacuation as soon as possible indicators of

safety for the evacuation, in addition to provision of adequate safety exits and evacuation from the outside of appropriate restrictions, security, export (including stairs, walkways and doors ) width must be appropriate.

(a) the safe evacuation of tall buildings index

1. Within the corridors of tall buildings, evacuation stairwell and the room door before the minimum clear width, and the basement, semi-basement room of personnel-intensive, room to evacuate the minimum total width of the export shall be calculated by the number of people 1m/100; < br>
2. The first floor outside the door to evacuate the minimum total width of the layer should be the largest number of people 1m/100 calculation. Evacuate the first floor hallway outside the door and the clear width of not less than the requirements of Table 3.4.1.1

3. With fixed seat auditorium, conference rooms and other crowded places, the Chamber evacuation corridor clear width at the minimum calculated by the number of 0.8/100 person, and not less than 1m; the Chamber evacuation corridor for the side aisles, not less than 0.8m; room and hall evacuation evacuation export a minimum total width of the aisle, flat ground should slope 0.65m/100 respectively the number of people through the calculation, the ground should be stepped respectively calculated by the number of 0.8m/100 people, and should not be less than 1.4m; auditorium evacuation of each evacuation, the average number of exports should not exceed 250.

4. High-rise building evacuation stairs on each floor should be the minimum total width calculated by the number of 1m/100 people; layers of varying sizes, its total width can be segmented basis, the lower the total width of escape stairs should be the upper layer of the largest number of calculations. The minimum clear width of escape stairs should request a small table 3.4.1.2.
