Do not always open: it is prohibited to manually keep the normally closed fire doors set on the evacuation walkway, the front room of the smoke proof staircase or the shared front room open during the use process to become "normally open" fire doors. In case of a fire, such "normally open" fire doors can not prevent smoke and fire;

Regular inspection: frequently check the integrity of the fire door, check whether the door closer and sequencer are in good use, whether the fire door can be closed automatically in order, and whether the screws on the hinge and hinge are loose. If damaged, immediately organize maintenance;

Decoration: one-sided pursuit of decoration effect, canceling the fire door frame and setting only the door pocket made of ordinary wood, replacing the original frame of the door leaf with other materials, and adding decorative surface layer in a large range, thus damaging the fire retardant coating and failing to achieve fire retardant effect;

Regular test: the normally open fire door shall be tested regularly to check whether its self closing control system, door closer, sequencer, release switch and other aspects are easy to use, whether it can effectively perform the self closing function in case of fire, and at the same time, it is necessary to resolutely prevent the random stacking of articles near the normally open fire door.
