The fire door is a kind of fireproof partition. In addition to the function of ordinary door, it can meet the fire resistance stability and integrity together with the frame in a certain period of time. It has the special function of fireproof, smokeproof and high temperature. In the event of fire , should have self-closing and signal feedback.
First, the problems in the use of fire door maintenance in the process of use
In order to facilitate the use of some units, the maintenance of normally closed fire doors has been opened for a long time (especially for buildings with frequent evacuation passages in public places such as shopping malls); some public entertainment places take the decoration effect into consideration, in order to pursue the overall unification and After the acceptance of the public security fire department, the beauty is immediately removed or replaced with ordinary doors; some hospitals provide buffer brackets at the protruding thresholds for the convenience of critically ill patients, so that the fire door maintenance is not strict; some people are obstructed when handling large items. The fire protection is turned on, so that the normally closed fire door maintenance door closer exceeds the maximum limit, and the normally closed fire door maintenance door closer is damaged, so that the fireproof door cannot be returned normally, and the fire door repairs the door frame and the door panel to be damaged. It loses its proper function of smoke and fire, completely loses its proper function, and cannot guarantee the safe evacuation of personnel.
Second, the root cause of problems in fire door maintenance
The occurrence of the above phenomenon has led to the failure of the fire door maintenance to fully play its due role in the fire. On the contrary, it is very likely that the safety of the fire door will be blocked due to the damage of the fire door maintenance. The main culprits are: First, China's current people's awareness of fire safety is weak; Second, the construction unit and the use unit are poorly managed, and their management has not been highly valued; second, the propaganda is not in place. In the fire safety inspection that the author participated in, some units encountered the above problems when they met the fire supervision department, saying that “there must be dozens of times a day, and ten times a yearâ€.
Third, the fire door maintenance has problems in the use process
First, extensively carry out publicity and education on the use, maintenance and management of fire protection facilities in the jurisdiction, and strive to improve people's awareness of fire protection and self-protection;
The second is to carry out fire protection and umbrella knowledge publicity and education training for the units equipped with fire door maintenance, and strive to let every employee understand the basic knowledge of the use, maintenance and management of fire door maintenance, and consciously participate in the maintenance and management of the door of life. Keep it in a state of readiness;
The third is to repair the fire door maintenance use, function and good use status and basic requirements in the fire door repair, write in the conspicuous position of the normally closed fire door repair: "normally closed fire door maintenance, please close at any time" to let customers and the public understand the fire prevention Basic knowledge of door repair;
The fourth is to carry out publicity activities to protect fire-fighting facilities and equipment, and mobilize everyone to participate in the protection of fire-fighting facilities such as fire door maintenance.
In 2004, the Ministry of Public Security has included the umbrella control and alarm escape door lock system in the key promotion technology project. In 2005, the Heilongjiang Provincial Public Security Department Fire Bureau issued the “Heilongjiang Provincial Public Security Department Fire Bureau on the promotion of application safety in the province. Notice of Control and Alarm Escape Door Lock System and New Technology of High Temperature Fireproof Soft Section, which requires the application of safety control and alarm escape door lock system in the province.
