What are Fire Doors and where are they required?

Fire doors are required in certain areas and play a vital role in helping to stop the spread of fire. According to the National Fire Protection Association, “A single-fire-door assembly can delay a fire for more than an hour and prevent it from spreading to the next compartment or floor.”

However, not all–fire code requires, it varies by cities and states.

Well, let us first understand what fire doors are and where they need to be used.

What Are Fire Doors?

The International Building Code (IBC) requires that “required” fire doors be equipped with an automatic closing device, except when the building is protected throughout with a smoke detection system capable of automatically initiating the release of the smoke detection system.

The IBC defines a “required” fire door as:

“A door opening into an exit, or which serves as an exit, including doors to stairways serving as exits, but not including interior corridor doors. A door is also a required fire door located between a Group A occupancy and an adjacent Group B occupancy or between a Group A occupancy and an unclassified occupancy.

As fire doors are so important, what are the advantages of them in our buildings ?

While fire doors are required in specific locations to provide adequate protection from fire, they also come with their own set of benefits. Some expected benefits include:

Stopping the spread of fire

Reducing the amount of smoke in a building

Limiting the amount of heat that enters or leaves a building

Helping maintain a comfortable temperature in a building

Where are They Required?

The type of business, the design of the building, and the fire exit location will all influence the fire door category. In cases where property preservation is essential, fire doors that protect for more than 60 minutes are sometimes specified. However, the primary consideration is always the protection of life.

Some familiar places where fire doors are required include:

Between public areas and corridors,

In exit stairways,

In elevator shafts,

In building lobbies,

In smoke-tight partitions,

In hazardous materials storage rooms,

In kitchen exhaust ducts,

Near heating and cooling equipment

In conclusion The specific requirements for fire doors will vary depending on the building’s occupancy classification and other factors. It is essential to consult with a local fire official to determine precisely where fire doors are required in your building.
