Office emergency exit stairs outside aisle used to move out when the office has many floors. Wall stairs are designed outdoors to facilitate movement and air circulation.
Nowadays, the factory construction project often has an auxiliary office item. Safety measures such as outdoor emergency stairs are always concerned in the construction of multi-storey office buildings.

The role of construction of outdoor emergency stairs

With the goal of being the safest and fastest way in the event of an incident. Usually when the office has a problem, all the electrical systems of the office will be cut off, so the skylight emergency staircase is the only thing that ensures the life and life of workers.

Standards for construction of outdoor emergency stairs

The distance from the emergency stairs to the furthest room, excluding toilets and bathrooms, must comply with the following regulations:
- The distance is 50m for rooms between two elevators or two exits, 25m for rooms with only one elevator, or auxiliary exits.
- Distance 40m between two ladders or exits, 25m for rooms with only one ladder or one exit to public houses, gymnasiums or apartments.
- Width of emergency exits and corridors is specified: 0.8m for doors; 1m for the passage of the door; 1.4m for corridor; 1.05m for the ladder.
- The height of doors and walkways is not lower than 2m; for basements, the vacuum floor must be lower than 1.9m; basement roof not lower than 1.5m.
- Fire ladder must meet: Width is at least 0.7m; the largest angle of inclination relative to the horizontal is not greater than 500, the ladder must have a handrail of 0.8m high.
- Number of stairs: Greater than 3 and less than 18 steps, do not use a spiral staircase with fan-shaped stairs to make an escape ladder, the largest angle of inclination of the ladder is 1:1.75.

Standards for staircase design

- Ensure 2 escape routes for high-rise buildings.

- The office building must have 2 emergency exits to ensure the evacuation of people in the building from the tallest building. The standard for emergency exit ladders in high-rise buildings is that the exit stairs must be on one side, the other side is a balcony design with an external escape ladder with an area of ​​​​less than 300m2 on each floor. The requirements for the design of the emergency ladder are:

- Go from the rooms on the first floor directly out or through the lobby to the outside;

- The bearing structure and cover must have fire resistance limit of not less than 60 minutes. Because when there is a problem, a large number of people move by emergency stairs is quite large, so there must be a structure that can withstand a rather large load.

- Fire doors must automatically close and be made of non-combustible materials with fire resistance levels greater than 45 minutes. Since this door has the role of optimal fire blocking when traveling on the emergency ladder, the fireproof material has a very important position and must definitely be selected according to the design of the exit stairs.

- There must be a projection system at the stairs when there is an incident

- Ladders must be ventilated so that the ground should not reach the floors and have an emergency exit to the roof.

Some other factors need to be considered before designing and constructing ladders, specifically:

- Construction site data.

- Building data such as people and structural data.

- Construction plan on safety and construction progress.

- Pre-construction site assessment.

- Ensure legal procedures before construction.

- Presenting project design drawings with detailed escape ladder design.

- Describe the structural drawings of the escape ladder in accordance with the standards and regulations.

- Analysis of pre-construction design drawings.

- The design of the escape ladder must ensure the space structure, the load-bearing structure and pay attention to ensure compliance with the prescribed standards.
