Can the residential fire door go?

Generally speaking, you can't leave people. If you leave people at will, once a fire breaks out, it will affect the normal use of fire exits. Secondly, according to the provisions of the National Fire Protection Law, the doors of fire exits should be kept open at any time, and articles or facilities should not be piled up in them at will, so as to avoid the rapid evacuation of personnel in case of danger. In addition, the residential property should also check the fire doors regularly to see if there is any damage.

1. What state should the fire door be in?

1. In general, fire doors in public places should be closed, but this closure does not mean locking. Fire fighting and other critical moments can be turned on at any time until the personnel arrive at a safe place. Fire doors should be closed, which can effectively prevent smoke from running around. Fire doors can play a good role in fire prevention and heat insulation, and win valuable time for personnel transportation.

According to firemen, once a fire breaks out, the circulation speed of smoke is still very fast, and once the fire spreads, it will get out of control. For example, if it is a 30-story building of 1, if the smoke is not blocked, it can spread from the bottom to the top after 30 seconds, which is enough to explain the role of fire doors.

Second, the residential fire escape requirements

1. In order to create convenient conditions for fire fighting and ensure building safety, circular fire lanes should be set around high-rise buildings in residential quarters. When the circular lane is difficult, fire lanes can be set along the two long sides of the high-rise building.

2. When the length of the building along the street exceeds 150m or the total length exceeds 220m, a fire lane passing through the building shall be set at an appropriate position. In order to prevent the collapse of building components from affecting the normal operation of the fire lane in case of fire, the fire lane should be 5m away from the external wall and at least 3.5m wide, and the width of the fire lane should not be less than 4m. There should be no obstacles below 4m above the fire lane. And keep it open 24 hours a day.

3. The clear width and clear height of the fire lane crossing the high-rise building shall not be less than 4m. Between the fire lane and the residential high-rise building, there should be no trees or overhead pipelines that hinder the operation of climbing fire engines.
