How far is the hotel safe passage?

20 18 distance between evacuation passages of hotel:

Should be calculated according to its fire resistance rating.

Safe evacuation distance refers to the maximum allowable distance from the farthest place in the building to the external exit or stairs. Safe evacuation facilities include safety exits, namely evacuation doors, corridors, stairs, emergency lighting and smoke exhaust facilities. The Code for Fire Protection Design of Buildings clearly stipulates the design standard of safety evacuation facilities.

When the number of users is less than 50, the minimum width of stairs, walkways and doors can be reduced appropriately; But the minimum width of the door should not be less than 0.80 meters. The number of safety exits should not be less than two; The width of aisles and stairs is designed according to the maximum number of people that can be accommodated on the floor, so they can be quickly evacuated from the scene in case of an accident, so it is necessary to ensure smooth flow and not to pile things up at will.

Extended data:

The requirements for setting fire exits stipulate that:

1. When it is really difficult to set evacuation stairs in high-rise public buildings, and the distance from any evacuation door to the entrance of the nearest evacuation stairwell is not more than 10m, the scissors staircase can be used.

2. When the top floor of a multi-storey public building with a first-class and second-class fire resistance rating of not less than two evacuation stairs is raised locally, when the number of the above floors does not exceed two, the sum of the number of people does not exceed 50, and the construction area of each floor does not exceed 200m2, 1 evacuation stairs can be set in the above parts, but at least 1 emergency exits directly leading to the flat roof of the main building should be set.

3. When the number of evacuees on each floor is different, the total clear width of evacuation stairs can be calculated by floor, and the total clear width of the stairs on the ground floor should be calculated according to the number of evacuees on this floor and above.
