Legal analysis
The national fire technical standard does not stipulate the opening direction of residential entrance doors, but only stipulates that the safety exit doors of business premises should be opened in the evacuation direction, which is usually called outward opening. For residential buildings, if the entrance door opens outward, it will usually reduce the effective width of the evacuation passage and affect the use of indoor fire hydrants, which should not be advocated. In the process of use, the entrance door shall not endanger public safety or hinder the passage of neighbors. At the time of design, all the entrance doors of the owner's house are designed to open inside. After the owner closes the house, it should not be opened to the outside world without authorization. Relevant departments have the right to require the owners who have changed the doors to the outside to carry out rectification. The Code for Fire Protection Design of Buildings has regulations on whether the entrance door is opened inward or outward, and all fire doors are opened from the outside. Fire door refers to the door that can cut off the fire source in case of fire. It not only meets the special requirements of fire prevention, but also has the function of an ordinary door, that is, it can be used by people at ordinary times and closed in time in case of fire, so as to limit fire and smoke in a limited area and effectively prevent the fire from spreading. Fire doors are divided into normally closed fire doors and normally open fire doors according to the open state. Normally closed fire doors are generally composed of fire doors, door frames, door closers and sealing strips. Two or more normally closed fire doors are also equipped with sequencers. Normally closed fire doors do not need automatic control design provided by electrical specialty, but there are some special cases, such as normally closed fire doors on evacuation passages. When some large-scale construction parties have management requirements such as anti-theft, the electrical specialty should cooperate with the design to reduce security risks as comprehensively as possible. For normally open fire doors, in addition to all accessories with normally closed fire doors, fire door release switches must be added, and automatic control design must be provided by electrical professionals. It is usually used in evacuation passages with more people and logistics.
