How can a fire rated door help during a fire?

Let’s take a minute to have a better understanding of the importance of fire doors. In the event of an actual fire, these doors can serve an important role in keeping flames and smoke from spreading to different parts of the building. They can also serve as a means of easy escape in case of an emergency.

Fire doors play a vital role in access control and protecting people and property from more than just the outdoor elements. These passive fire protection systems are designed to protect an opening with a fire-rated barrier.

Fire doors are typically used to protect openings in exits, such as fire-rated stair enclosures, fire-rated exit corridors, and horizontal exits. They’re also installed in fire barrier openings that are designed to protect your building and its occupants from specific hazards, as well as compartmentalize your building into specific fire areas

Building and fire codes require fire doors to pass a fire-resistance test that’s conducted by an independent testing agency. The standard test procedure for fire doors can be found in NFPA 252: Standard Methods of Fire Tests of Door Assemblies. The doors are tested as a complete assembly, which includes the door leaf, hinges, the latch, the closing device, and the frame.

All fire doors are subject to fire tests conducted by national test agencies and must withstand the rigors of the fire test.
