In today's era of frequent disasters, fire doors can effectively isolate dangerous flames and smoke in the event of a fire, and can become a life-saving "door to life and death". Daily fire doors need to be cleaned and maintained regularly in order to better function in the event of a fire. Do you know how to clean and maintain fire doors? Below are some tips for cleaning and maintaining fire doors.
& nbsp;
& nbsp; 1、 Prevent the normally closed fire doors installed in evacuation corridors and smoke proof staircases from being assumed to be normally open during use, becoming "normally open" fire doors. Once a fire occurs, such "normally open" fire doors will not have any smoke blocking or fire prevention effect.
& nbsp; 2、 Regularly check the integrity of the fire doors, check if the door closers and sequencers are functioning properly, and if the fire doors can automatically close in sequence; Are the screws on the hinges and hinges loose. If there is any damage, immediate repair should be organized.
& nbsp; 3、 Eliminate the use of units that, in pursuit of decorative effects, cancel the fireproof door frame and only install ordinary wood door frames, replace the original frame of the door leaf with other materials, and extensively add decorative surfaces, thereby damaging the fireproof layer and failing to achieve the fireproof effect.
& nbsp;4、 Regular testing should be conducted on normally open fire doors to check whether their self closing control system, door closers, sequencers, release switches, and other aspects are effective and whether they can actually function as self closing when they occur. At the same time, it is necessary to firmly prevent the indiscriminate stacking of items next to normally open fire doors.
