1. Questions in the use of fire doors
Some units keep the normally closed fire doors open for a long time for the convenience of use (especially in shopping malls and other public venues that use scattered passages to build frequently); some public entertainment venues take into account the decorative effect, in order to seek overall consistency and After being inspected by the public security fire protection organization, it will be dismantled or replaced with a normal door immediately;
Some hospitals set up buffer brackets at the outstanding threshold for the convenience of critically ill patients, which makes the fire doors not tight; some people forcefully open fire doors when transferring large items and obstructed, so that the normally closed fire door closers exceed the maximum limit. The normal closed fire door closer is damaged, causing the fire prevention to fail to return to the normal position. In the worst case, it causes the fire door frame and door panel to be damaged, so that it loses its due smoke and fire prevention effects, and completely loses its due function. , It is impossible to guarantee the safety and decentralization of personnel.
2. Reasons for doubts about fire doors
The appearance of the above scene caused the fire door to not fully exert its due effect in the fire. On the contrary, it is very possible that the damage of the fire door will cause the occurrence of blockage and safety dispersion. The main culprits are:
One is that everyone's fire safety awareness in China at that time was indifferent;
The second is the improper handling of the construction unit and the application unit, and its handling has not led to high attention; the second is that the publicity is not in place. In the fire safety inspection that the author participated in, when some units encountered the above-mentioned doubts by the fire supervision department, they said, "It needs to be shut down dozens of times a day, and repaired more than a dozen times a year" and so on.
