What is the purpose of a fire door ?
The purpose of a fire door is to slow the spread of fire and smoke, and to provide a means of escape in the event of a fire. Fire doors are designed and tested to withstand the spread of fire for a certain period of time, typically 30 or 60 minutes, and are made of materials that will not easily ignite or support combustion.
A fire door is typically made of steel or wood and is equipped with a self-closing mechanism and smoke seals. The self-closing mechanism ensures that the door will close automatically in the event of a fire, while the smoke seals help to prevent smoke from entering the building.
Fire doors are often used in buildings as part of a fire-rated barrier system, separating different areas of a building or providing a means of escape in case of fire. They can be found in commercial buildings, residential, industrial and institutional buildings, apartment buildings and other occupancies.
It's important to note that fire doors need to be maintained properly, by keeping them clear of obstructions and ensuring that the self-closing mechanism and smoke seals are functioning properly. The fire door should also be closed at all times except when entering or exiting.
