Why need to do the fire rated door building inspection?

The building inspection services help identify critical fire, life safety and security building improvements needed to achieve code compliance with the ultimate goal of achieving fire, life safety and security of the building.

 

During everyday use, a fire door seems just like any other door. But when a fire occurs, these doors prevent fire from spreading from the area of origin to other protected areas within the building.

NFPA 80 recommends that a periodic inspection and maintenance program be implemented and is the responsibility of the property management.

The NFPA 101 Life Safety Code also requires certain doors in specified occupancies to be inspected and tested not less than annually, and the International Fire Code requires openings in required fire walls, fire barriers and fire partitions to be maintained in accordance with NFPA 80。

Life Safety Code requires documentation of these inspections, and NFPA 80 requires the following items to be verified:

1. No open holes or breaks exist in surfaces of either the door or frame.

2. Glazing, vision light frames, and glazing beads are intact and securely fastened in place, if so equipped.

3. The door, frame, hinges, hardware, and noncombustible threshold are secured, aligned, and in working order with no visible signs of damage.

4. No parts are missing or broken.

5. Door clearances at the door edge to the frame, on the pull side of the door, do not exceed clearances listed in 4.8.4 and 6.3.1.

6. The self-closing device is operational, that is, the active door completely closes when operated from the full open position.

7. If a coordinator is installed, the inactive leaf closes before active leaf.

8. Latching hardware operates and secures the door when it is in the closed position.

9. Auxiliary hardware items that interfere or prohibit operation are not installed on the door or frame.

10. No field modifications to the door assembly have been performed that void the label.

11. Casketing and edge seals, where required, are inspected to verify their presence and integrity.

 

Each fire rated door must ensure that an annual professional unit (AHJ) checks and signs a permit report to ensure that each fire door is in good condition.

 

Fire rated doors have a wide and important application in commercial and residential buildings, especially in high-rise buildings. Fire doors play an invaluable role in controlling fire spread, reducing fire damage and ensuring that people escape smoothly in a fire. Check the fire proof door and supporting hardware for damage, to avoid the fire door losing its fireproof effect in the event of fire.
