How To Spot A Fire Door Quickly

Being able to identify a fire door is very important for building owners, managers and homeowners. Here are some of the key things to look for.

As we know, a fire door is a door that has been rated for protection against heat and smoke for a certain amount of time. But how do you identify a fire-rated door? It is essential that you know your doors inside and out first to identify what your rating is and also to be able to determine if there are any issues.

Having the ability to scan for doors quickly is necessary for any building manager or homeowner. Here are some easy ways to identify a fire door.


The easiest way to identify if your doors are fire-rated is to look for the appropriate signage. This goes for all states across Australia.

In NSW, it is a little different. Here, regulations call for more comprehensive signage:

For all other states, the Building Code of Australia stipulates that the following sign must be displayed on all fire doors:





The signage must be clearly visible in all states, meaning that it will be straightforward to spot. You can read more about fire door signage here.

Automatic Locking Devices

Another surefire way to identify a fire door is to see if it is fitted with an automatic locking device.

According to the Building Code of Australia, all fire doors and smoke doors must close automatically if a fire alarm or emergency alarm is sounded. This is achieved by a device such as a Magnamatic system. These systems are triggered by an alarm, which locks a door in place, stopping the fire from spreading between parts of a building. This also helps direct the flow of foot traffic to safety.

The devices are usually mounted on the floor beneath the door or a wall behind the door; they can also be installed on the ceiling.

Compliance Tags

Aside from the more obvious signage that will help you identify a fire door at a glance, there should also be compliance tags that are fitted to doors with more information about their fire rating.

A compliance tag confirms that the attached door has been tested, installed correctly, and can uphold the relevant fire-resistant rating. Here you will find all relevant information about the doors, including their fire/time rating, manufacture date, owner’s name, certifier’s name and item serial number.

These tags must remain on the door at all times. However, they can sometimes fall off, so if yours are missing, make sure they are replaced immediately to avoid compliance issues.

Other Things To Look For

• Is your glass door more than 1/4 inches thick? This is the minimum requirement for a glass fire door or glass panel in a fire door (roughly 6.38mm).

• Check if a louvre is present on the door – these are slats (usually metal) that allow smoke to pass through.

• Look at the gaps between doors and frames – they should be very minimal.
