Many citizens, when renovating their new homes, find the fire doors installed by developers unattractive and replace them with ordinary anti-theft doors, without realizing that this has planted certain fire hazards. The Fire Protection and Bonded Brigade reminds citizens that fire doors play an important role in blocking smoke in a fire and should not be replaced without authorization.

According to fire safety supervisors, some developers have installed fire doors before selling their houses in accordance with fire safety technical standards. The main functional difference between fire doors and ordinary anti-theft doors is that the filling inside the fire door is made of specialized fire-resistant and flame-retardant materials, and uses fire-resistant expansion sealing strips, which can expand and block smoke when exposed to high temperatures. Ordinary anti-theft doors are mainly composed of steel frames and soundproof cardboard, and the sealing strips are also ordinary strips, which do not have the function of blocking smoke.

The fire department reminds that fire doors can prevent the spread of fire and smoke in the event of a fire, ensuring the safe evacuation of personnel. Their installation and use comply with national standards. At present, although there is no mandatory requirement for homeowners to use the fire doors installed by developers in China, for fire safety reasons, it is recommended that homeowners do not modify or replace them without authorization. If replacement is indeed necessary, it is necessary to purchase doors with fire and theft prevention functions produced by regular manufacturers and hire professional personnel to install them.
