Do fire doors have to open outwards?

Many people have doubts about a problem with fire doors, that is, must the fire doors be opened to the outside?
Whether the fire door should be opened or not is related to the efficiency of the door and the safety of the building. For this problem, it needs to be determined according to the actual situation of the building and the safety requirements.
According to the national “Building Design Fire Protection Code” (GB 50016-2014), the opening direction of the fire door should be consistent with the direction of personnel evacuation. However, if the closing direction of the fire door is consistent with the direction of personnel evacuation, it will cause safety hazards, such as affecting evacuation. The width or shape of the passage leads to excessive density of evacuated personnel, so the opening direction of the fire door can be adjusted appropriately to make it open inward, which can also increase the efficiency of evacuation. In addition, whether the fire door should be opened to the outside is also related to the function of the building. Some public buildings, such as hospitals, schools, etc., may have the requirement to isolate dangerous areas. At this time, the fire doors need to be opened inwards to ensure the closure and safety of dangerous areas, while some commercial buildings, residences, etc. need to be protected from The smooth flow from the inside of the building to the outside, at this time, the fire door needs to be opened to the outside.
Generally speaking, whether the fire door should be opened to the outside depends on the specific situation and safety requirements of the building. If the fire door is opened to the outside and is safe to use, it can be opened to the outside to improve evacuation efficiency and convenience. If the inward opening of the fire door is more in line with the use requirements and safety standards, it should be opened inward to ensure the closure and safety of the dangerous area. It should be noted that no matter whether the fire door is opened inside or outside, it needs to be evaluated and approved by safety professionals, and comply with relevant national standards and regulations, so as to ensure effective fire prevention, evacuation and the safety of personnel.
