Fire Doors

Fire Doors along with hardware are part of a fire protection system in a building or a home that work to make an area as safe as it can be in a fire. It is known as passive fire protection. Fire doors and hardware are constructed to be heat resistant and prevent fires from spreading for a designated amount of time. (3 hour, 1  hour,  or 20 min.) Fire doors and hardware are then tested and certified for flame retardation through a testing agency. The most widely recognized agencies are Underwriter’s Laboratories, Inc. UL and Warnock-Hersey (WH).

Annual Fire Door Testing Enforces the NFPA 80 Standards

Fire Door Drop Test

Drop testing a door refers to a test made on either horizontal or vertical sliding doors or rolling doors. This test makes sure the doors will drop or close automatically if there is a fire. The doors are then reset according to the manufacturers instructions. The National Fire Protection Association, or NFPA, have made it a requirement that once a year all rolling doors be inspected for proper operation and full closure and drop tested once a year.

Fire Door Test For Rolling Doors

The exterior of the rolling door is visually inspected and checked to make sure there are no hazards during testing. All moving parts and hardware are then checked for damage and the door is checked for proper closure. The test on rolling doors includes an operational test commonly called a “drop test”. This test makes sure that the door will drop or close during a fire. Two drop tests are required; one for proper operation and full closure, and the second drop test is to verify that the automatic closing device has been reset correctly.

Fire Door Testing For Swinging Doors

The exterior of the door and the door’s hardware is visually inspected to see if there is any damage on the door or any part that may be missing. When the door is safe to test all parts and closures are inspected and tested.

Fire Door Test For Metal Doors

After the exterior of the door is visually inspected the metal doors or Kalamein Doors and tin clad doors are checked on the inside for wood rot. The doors hardware is inspected for any damage, and closures are checked to make sure they are working correctly.

Area Surrounding Fire Door

The area directly surrounding the fire door should not be blocked or have any material around it that may fall and prevent the door from closing. There should also not be anything stacked against the door. Sometimes a barrier has to be built so that nothing is piled against the inside of the door.

Fire Door Test Written Records

It is required to maintain written records of the Fire Door Test and Inspection so that they can be made available to the AHJ, the Authorities Having Jurisdiction, usually the local Fire Marshal.

Fire Rated Doors Purpose

A fire rated door, frame & hardware must prevent the spread of flame though the opening for a designated period of time
(3 hour, 1 ½ hour, ¾ hour or 20 min.)

Fire Door Certification

Fire rated doors, frames, and hardware must be tested for flame retardation. These tests can be performed by various testing organizations.

Fire Rated Doors Hardware

It is important that only UL labeled finished hardware be placed on the fire rated door and frame. Non-labeled hardware, which possibly could fail during a fire, defeats the purpose of labeling the door and frame.
