A Beginner’s Guide to Fire Doors

Fire doors are an essential part of a building’s fire protection model and are a crucial piece of infrastructure needed to keep residents safe. Fire doors stop the spread of smoke and flames between different areas of a building, while also working to prevent smoke from entering into isolated areas such as fire exits and corridors, where people could become trapped in the advent of an emergency.

It is important to know how exactly fire doors work to keep your building and its occupants safe. Let’s take a look at the different parts and properties of fire safe doors.

Fire Resistance Level

What makes a fire door a ‘fire door’ is its compliance with the National Construction Code,
which dictates that doors are tested to certain specifications, namely AS1530.4. Fire doors are tested to make sure that they meet the “fire rating” or “fire resistance level” (FRL) is in accordance with the Building Code of Australia. There are three main points contribute towards a doors FRL:
Structural adequacy or the doors ability to maintain stability in accordance with AS 1530.4.
Integrity or the doors ability to resist flames and gases in accordance with AS 1530.4.
Insulation, meaning a door’s ability to maintain a temperature below a specified limit when tested in accordance with AS1530.4.

The sum of these three properties contributes towards a door’s fire rating, which is essentially a door’s ability to resist heat and flames.

Compartmentalisation

Compartmentalisation is one of the key ways that fire doors work to keep residents of a building safe from fire, while also containing the smoke and flames. Compartmentalisation stops the fire from spreading to isolated areas such as hallways and corridors, passageways that residents use to escape in the case of fire. Compartmentalisation also stops smoke and flames from spreading through to different rooms and other buildings. Magnamatic devices are specialised types of hardware that are installed in doors to hold them open. When an alarm is triggered the device automatically closes the door via a hydraulic system, which stops the spread of flames to different parts of the building.

Fire Doors Seals

High quality seals are an important part of a fire doors hardware as they reduce the severity and damage of a blaze by preventing it from spreading around the door’s leaf. Quality seals expand when they are exposed to high temperatures, providing a barrier against flames and smoke.

Fire Doors Signage

Fire door signs are an integral part of a buildings fire protection model as they display information that spreads awareness about fire safety. Regulation regarding signage differs depending on states around Australia so be sure to read more about signage here.
