Building Design Fire Code 2015 which stipulates the direction of the entrance door

1. According to the safety regulations of doors and windows in the "Code for Fire Protection Design of High-rise Civil Buildings": The fire door should be a swing door that opens in the direction of evacuation, and should be able to be opened manually from either side after closing.

2. According to the "Code for Fire Protection Design of Buildings", the evacuation doors in the building should comply with the following regulations: the evacuation doors of civil buildings and factories should be opened in the direction of evacuation. Except for Class A and B production rooms, when the number of people does not exceed 60 and the average number of evacuees per door does not exceed 30, the opening direction of the door is not limited.

3. According to the provisions of the common part of the "Residential Design Code": the doors of the stairwell and the front room should be opened in the direction of evacuation.

Fire doors in walkways, stairwells, and antechambers used for evacuation should have a self-closing function. Double and multi-leaf fire doors should also have the function of sequential closing. Normally open fire doors, when a fire occurs, should have the function of self-closing and signal feedback.

The entrance door is designed to open outwards mainly based on fire safety considerations. The instinctive reaction of ordinary people in the event of a dangerous situation such as a fire is to push the door out, so the entrance door is designed to be in the direction of evacuation. Public buildings, for example, are less likely to have entrance doors designed to open inward.

In places where it is difficult to set up firewalls, fire shutters can be used as fire partitions. When the fire roller shutter including the temperature rise of the backfire surface is used as the fire resistance limit judgment condition, the fire resistance limit is not less than; When the fire roller shutter that does not include the temperature rise of the back fire surface is used as the fire resistance limit judgment condition, the two sides of the roller shutter shall be protected by an independent closed automatic sprinkler system, and the duration of the system water spray shall not be less than.

The Code for Fire Protection in Buildings GB50146-2014, 6, stipulates the opening direction of evacuation doors in buildings.

Explanation of Provisions:

There are provisions in the fire protection code, and the description of the provisions also clearly explains that the opening in the direction of evacuation is carried out"It refers to public buildings, with a large number of people, unfamiliar with the site, and easy to panic in case of emergency, so there are requirements for opening out; For spaces with no more than 60 people, there is no restriction on the direction of the door opening; There are only a few people in each household in the house, and everyone has lived here for a long time, and there is no unfamiliar environment and unfamiliar site. Therefore, the opening direction of the evacuation door can be unlimited.

In addition, the Residential Design Code and its interpretation also explain this: "If the opening of doors and windows in a dwelling affects the safety of public parts, the doors or windows should be opened inward, even in high-rise buildings." "If the entrance door of the residents close to the elevator entrance or the main passage is open outward, it will affect the normal use of the passage, and the entrance door should be opened inward.
