Q:What is the basis for saying that anti-theft door is conducive to fire safety

Anti-theft door to open to the outside, the user is conducive to the evacuation of the fire, but because of the open to occupy the public evacuation channel, therefore, on the whole Gong hold the bar to visit the amount of poetry and sails fire safety is unfavorable. First, the past design of the residential door, are open inward, its purpose is to avoid obstruction of the stairway traffic, but because there is no security measures, generally converted or installed by the residents to open the security door. In this case, in 1999, when the "Residential Design Code" was revised, the provisions on the safety doors were considered to be increased, and the requirements for safe evacuation should not be prevented when the opening should be prevented. Second, see the details of "residential design specifications" (GB-1999) "Article 3.9.4: residential door should be used security guard door. Open the door should not interfere with traffic." Can be seen from the overall interests of the building to consider, outside the door is unfavorable, because the outside of the door occupied part of the public walkway area, adverse fire evacuation. But for the tenants, because this increased the effective use of indoor area, so more recognized. Third, we can see, the standard does not have anti-theft door (security defense door) inside and outside to do a clear request, inward, outward can be, but to open to pay attention to "should not interfere with traffic." Because you are the late conversion of the door, in the early design process, the corridor is in accordance with the door to open the case of the design, you now open to open, must hinder the traffic, therefore, usually should not be changed to open. It should be noted that this situation refers specifically to the security guard, if the door is not a security guard door, into the open is not appropriate.
