How long does a fire door last?

Fire safety is a critical aspect of any building design and maintenance. Among the various fire safety measures, the proper installation of fire doors is of utmost importance . These specialized doors act as barriers to the spread of fire and smoke, giving residents and office workers the time they need to evacuate.

Understanding the durability of fire doors and their different characteristics is vital to ensuring the correct fire safety measures are in place in your building.

Fire door fire resistance standards

Fire doors are classified according to their resistance to fire over a certain period of time. They are rated as follows:

FD30 – 30-minute protection

FD60 – 60 minute protection

FD90 – 90-minute protection

FD120 – 120 minute protection

Each rating indicates the length of time the door can contain fire and smoke, preventing it from spreading to other areas.

These assessments play an important role in determining which fire doors are most suitable for different buildings, taking into account the potential fire hazard and the time required for occupants to safely exit.

What role do fire doors play in safety?

• Fire doors prevent the rapid spread of fire and toxic smoke within a building. This provides the time necessary for safe evacuation and protects lives.

• Doors create "fire zones" within a building. As a result, a fire cannot spread throughout the entire area at once. This is especially important in large buildings such as offices, hotels, schools and hospitals.

• Saving time means that emergency services are given more time to respond, which can reduce damage to equipment, documents, and valuable property.

In industrial facilities where the risk of fire is particularly high, high-class (e.g. FD90 or FD120) fire doors are used, which prevent the spread of fire for a long time and give emergency services more time to respond.

To ensure the safety and efficiency of fire doors, they must be regularly inspected and maintained, as damage or malfunctions over time may affect their functionality. In case of damage or non-compliance with standards, they must be replaced promptly.
