The installation of fire doors and windows should refer to authoritative technical documents such as the *National Building Standard Design Atlas*, for example, *National Building Standard Design Atlas: Fire Doors and Windows* (03J609, now replaced by 12J609). These atlases provide selection drawings, detailed drawings, and installation details for fire doors and windows made of various materials such as steel, wood, and stainless steel, serving as important bases for design and construction. The installation dimensions of fire doors must comply with national standards. Common residential fire doors are generally 2.1 meters high and 1.1 meters wide per leaf, sufficient for the passage of ordinary furniture and appliances. Fire doors are mostly installed on structural walls (such as shear walls) and should not be arbitrarily removed or altered after installation. Provided they comply with regulations, fire doors can sometimes be used as unit doors or other daily passageways, but their fire-resistant function must not be compromised. High-quality fire doors also use fire-resistant smoke-blocking strips that expand and fill door gaps when exposed to high temperatures, effectively preventing the spread of toxic fumes.
Fire doors are often called "lifelines" because they remain closed during a fire, effectively blocking fire and smoke and buying precious time for evacuation and rescue operations. Public awareness of the correct use of fire doors is equally important, and relevant fire safety education materials (such as "Are Fire Doors Unburnable?", which won first prize in 2024) can help raise this awareness.
