Fire doors are designed to restrict the spread of fire and smoke, but wedging them open can prevent them from performing their intended safety function.

Fire doors are an important part of a building’s passive fire protection system. They are designed to help compartmentalise areas by limiting the movement of fire and smoke through doorways. However, a fire door can only provide this protection when it is properly installed, maintained and allowed to close as intended.

Wedging, propping or otherwise holding a fire door open may seem convenient, particularly in busy buildings where people frequently move between rooms or corridors. However, keeping a fire door open can compromise the purpose of the fire door and increase risks for occupants, building owners and facility managers.

For buildings requiring compliant fire doors in Sydney, understanding why fire doors should remain closed and how they should operate is an important part of effective fire safety management.

What Is the Purpose of a Fire Door?

A fire door forms part of a building’s passive fire protection strategy. When a fire occurs, the door is intended to help separate areas of the building and slow the movement of flames and smoke.

Unlike a standard internal door, a fire door is designed as part of a tested door assembly. Its performance depends on multiple components working together, including the door leaf, frame, hinges, seals, hardware and closing mechanism.

A fire door should therefore not be treated simply as an ordinary door that can be left open whenever convenient. Altering how the door operates can affect the performance of the complete assembly.

For this reason, building owners and facility managers should ensure that doors are installed and maintained correctly. Proper fire door installation in Sydney is an important consideration when establishing a reliable passive fire protection system.

Why Do People Wedge Fire Doors Open?

Fire doors are often located in corridors, stairwells, entrances, storage areas and other locations where people move frequently. This can make them inconvenient when they are required to close automatically.

Some common reasons people may attempt to keep fire doors open include:

• Improving ventilation between areas
• Making movement through a building easier
• Preventing repeated opening and closing
• Moving equipment or materials through doorways
• Keeping busy corridors accessible
• Reducing the need to physically open the door

Although these reasons may appear practical, they do not override the function of a fire door.

A fire door that has been deliberately wedged open may remain open when a fire occurs. This can allow smoke and flames to travel through the doorway instead of being restricted by the fire-rated barrier.

How Does Wedging a Fire Door Increase Fire Risk?

The main problem with wedging a fire door open is that it can prevent the door from performing its intended role during an emergency.

When a fire develops, smoke can spread rapidly through open spaces. A closed fire door helps limit the movement of smoke and fire between designated areas. If the door is held open, that separation may no longer be effective.

This can have several consequences.

Faster Movement of Smoke and Fire

An open doorway provides a direct route between areas of a building. Smoke can move through this opening and affect other parts of the property.

This is particularly concerning where fire doors are installed between compartments or along protected routes.

Reduced Protection for Occupants

Fire doors can help maintain safer conditions by limiting the spread of fire and smoke. If they are held open, occupants may have less protection from conditions developing on the other side of the doorway.

Increased Risk to Escape Routes

Protected corridors and stairways can be particularly important during evacuation. Fire doors in these areas may help separate escape routes from areas affected by fire.

Keeping these doors open can undermine the protection they are intended to provide.

Potential Compliance Problems

Fire safety requirements apply to the design, installation, maintenance and operation of fire safety systems. A fire door that is deliberately prevented from closing may create concerns during inspections or compliance assessments.

Building owners and managers should therefore ensure that fire doors are used according to their intended purpose and maintained appropriately.

Why Fire Doors Must Be Able to Close Properly

A fire door is not effective simply because it has a fire rating. The door must also be able to operate correctly as part of its complete assembly.

The closing action is particularly important. If the door cannot close fully, gaps may remain around the opening, reducing the effectiveness of the barrier.

Several factors can affect the ability of a fire door to close correctly, including:

• Damaged or unsuitable hinges
• Faulty door closers
• Incorrect hardware
• Obstructions around the doorway
• Misalignment
• Damaged seals
• Excessive gaps
• Unauthorised modifications

Regular inspection can help identify these problems before they affect the performance of the door.

The surrounding components are also important. For example, fire door seals are designed to form part of the door assembly and can contribute to controlling the passage of fire and smoke when properly installed and maintained.

Why Fire Door Hardware Matters

Door hardware plays an important role in allowing a fire door to operate correctly. Handles, hinges, locks, closers and other components must be suitable for the application and compatible with the door assembly.

Installing an inappropriate component or modifying existing hardware without proper consideration can affect the operation and performance of the door.

For this reason, fire door hardware should not be selected purely based on appearance or convenience. It should be appropriate for the door and its intended application.

Building owners and managers can review suitable fire-rated door hardware in Surry Hills when managing fire door requirements in that area.

Similarly, facilities in Bondi Junction can consider appropriate fire-rated door hardware in Bondi Junction as part of their overall door safety requirements.

The Importance of Fire-Rated Door Frames

The frame is another essential component of a fire-rated door assembly. A properly selected and installed fire-rated frame helps support the door and contributes to the performance of the overall opening.

A fire-rated door should therefore not be considered independently from its frame.

If a replacement door is installed into an unsuitable frame, or if the frame has been damaged or improperly modified, the performance of the complete assembly may be affected.

For buildings requiring suitable supporting components, fire-rated door frames are an important consideration when planning or maintaining fire-rated openings.

What Should Be Used Instead of Wedging a Fire Door Open?

If a fire door needs to remain open for operational reasons, simply placing an object underneath it is not an appropriate solution.

The correct approach depends on the building, door assembly and applicable requirements. Where an open position is genuinely required, building owners should seek advice from a qualified fire door professional about suitable compliant solutions.

The key consideration is that the door should still be capable of providing the required protection when needed.

Regular maintenance is equally important. A door that closes correctly when first installed may develop operational problems over time due to wear, damage, building movement or changes to hardware.

How Building Owners Can Reduce Fire Door Risks

Building owners, property managers and facility managers can take several practical steps to reduce risks associated with fire doors.

Keep Fire Doors Unobstructed

Do not use wedges, bins, furniture, doorstops or other objects to hold fire doors open unless an appropriate approved system is specifically provided.

Check Door Operation Regularly

Doors should be checked to ensure that they open, close and latch correctly. Any noticeable changes in operation should be investigated.

Inspect Seals and Hardware

Damaged seals, loose components and faulty hardware should not be ignored. Appropriate repairs should be arranged when problems are identified.

Avoid Unauthorised Modifications

Drilling, cutting, replacing hardware or making other alterations can affect a fire door assembly. Changes should be assessed carefully before work is carried out.

Use Qualified Professionals

Fire-rated doors require appropriate knowledge during installation, inspection and maintenance. Working with experienced professionals can help ensure that the door assembly remains suitable for its intended purpose.

For properties in Surry Hills, businesses can also review available fire-rated doors in Surry Hills when assessing their fire door requirements.

Why Regular Fire Door Inspections Are Important

Fire door safety is not a one-time responsibility. Doors can experience regular use, impact, wear and environmental conditions that affect their operation.

During inspections, attention should be given to the overall condition of the door and frame, closing action, hardware, seals, gaps and other relevant components.

If a door does not close correctly, it should not simply be wedged open or ignored. The underlying issue should be identified and addressed.

Regular inspection and maintenance can help building managers identify defects early and support ongoing fire safety management.

FAQs About Wedging Fire Doors Open

1. Is it safe to wedge a fire door open?
Generally, a fire door should not be wedged, propped or otherwise held open in a way that prevents it from performing its intended function. If an open position is required, an appropriate compliant solution should be assessed by a qualified professional.

2. Why do fire doors need to close automatically?
A fire door needs to close so that it can act as part of the building’s fire separation system. If it remains open, smoke and fire may be able to move through the doorway more easily.

3. Can furniture be used to keep a fire door open?
Furniture, doorstops and other objects should not be used to hold fire doors open. Such obstructions can prevent the door from closing when it is needed.

4. What happens if a fire door does not close properly?
A fire door that fails to close or latch correctly may not provide the expected level of protection. The cause should be identified and addressed rather than using an object to keep the door in a particular position.

5. Are fire door handles and frames important?
Yes. Fire-rated door assemblies rely on compatible components, including suitable hardware and frames. The condition and suitability of these components can affect how the complete door assembly operates.

Conclusion

Fire doors are an important part of passive fire protection, but their effectiveness depends on correct installation, suitable components, proper maintenance and appropriate use. Wedging a fire door open can prevent it from closing when required and may allow smoke and fire to spread between areas of a building.

Building owners, facility managers and other responsible parties should avoid treating fire doors like ordinary internal doors. Regular checks of the door, frame, seals and hardware can help identify issues that may affect performance.

Where fire doors need to remain open for operational purposes, the appropriate solution should be assessed by a qualified professional rather than relying on wedges or other temporary methods. Maintaining properly functioning fire doors in Sydney can support a safer and more compliant building environment.
