The occurrence of fire is the most common, the most prominent and the most harmful disaster in real life, and it is a major issue directly related to the safety of people's lives and property. Therefore, fire safety is very important in daily production and life. In high-rise buildings and public places with a large flow of people, fire doors are also an indispensable part of fire safety management. The application of fire doors ensures our life safety. The installation of fire doors that meet fire standards has become a mandatory requirement for fire acceptance.
What are Fire Doors?
Fire doors refer to doors that can meet the requirements of fire resistance stability, integrity and thermal insulation within a certain period of time. In addition to the function of ordinary doors, fire doors also have the function of preventing the spread of fire and the spread of smoke. It can prevent the spread of fire within a certain period of time, ensure the evacuation of personnel to buy time for escape and fire fighting, and use it with fire exits to minimize fire losses. The approved laboratory designated by the Ministry of Fire and Economic Affairs, according to the national/international standards for fire doors, the fire door fire resistance test method, and obtained the verification registration certificate and authorized logo issued by the Standard Inspection Bureau of the Ministry of Economic Affairs, is called a fire door.
What is the function of a fire door?
The normally open fire door is usually kept open to facilitate the passage of personnel, ventilation and lighting. Once a fire occurs, when it is in the open state, it can be automatically closed through the linkage control system, effectively ensuring the reliable closing of the fire door in the fire, so as to prevent the spread of fire and prevent the spread of smoke and toxic gases.
The normally closed fire door can effectively block the invasion of thick smoke and fire after a fire occurs, so it is one of the important measures for fire protection. If the normally closed fire door is in an open state, once a fire breaks out, it will not be able to prevent the spread of the fire and prevent the spread of smoke.
