Guangdun Fire Doors: Extending Life Pathways by 5400 Seconds
Evacuation doors and fire doors may sound similar and serve seemingly related purposes, but are they truly the same? Here, Guangdun Door Industry clarifies the distinctions between the two.
Evacuation Doors
Also known as safety doors, evacuation doors are external doors or stairwell doors in buildings that provide safe egress during emergencies. In rare instances, they may refer to doors connecting rooms to hallways.
Notably, evacuation doors are not necessarily fire doors. For example, in a small five-story office building where each floor is 900 square meters, the stairwell can be either open or closed. If it is a closed stairwell, the door may simply need to resist smoke and have a window for visibility, rather than being classified as a fire door. Similarly, a Class C fire door installed in a pipe shaft does not imply that the two types of doors are directly related.
So, is an evacuation door a fire door? Does a fire door possess evacuation functionality? While both types of doors play essential roles in ensuring safety, their functions are distinct.
Fire Doors
Fire doors are designed to meet specific requirements for fire resistance, integrity, and insulation over a set period. Typically located in fire separation zones, evacuation stairwells, and vertical shafts, these doors are critical for blocking flames and toxic smoke.
The primary function of a fire door is to contain fire and smoke, which means they must withstand fire tests and adhere to higher material standards than evacuation doors. Importantly, during a fire emergency, fire doors must close securely. While both evacuation doors and fire doors serve critical functions, one is designed for openness during normal conditions, while the other is expected to provide security in emergencies.
Requirements for Fire Doors in Evacuation Areas
In areas designated for fire separation, evacuation doors must not only prevent fire and smoke but also facilitate safe passage for individuals. This necessitates the use of Grade A fire doors. For high-rise buildings, densely populated public structures, and multi-story Class C factories, the doors in closed stairwells should be Grade B fire doors that open in the direction of evacuation. Other buildings can utilize double-acting spring doors.
Fire doors are typically installed in high-risk areas or rooms of significant importance, including firewalls and doors leading into stairwell anterooms. Therefore, the method of operation and direction of opening for fire doors must ensure rapid accessibility and avoid obstruction in emergencies. A well-installed fire door must maintain the integrity of fire separation while enabling convenient egress for occupants.
Constantly Open Fire Doors
In frequently accessed areas within buildings, it is advisable to install self-closing fire doors. These doors should automatically close during a fire and include feedback signaling. This means that, like evacuation doors, fire doors can remain open during normal operations but will close in emergencies.
