Fire doors play a crucial role in controlling the spread of fire, protecting lives, and safeguarding property. They’re an essential part of fire protection strategies in buildings, but do you know what's true and what's false when it comes to fire doors? Take our quiz below and learn what's fact and what's fiction when it comes to the safety and regulation of your building.
Fire doors play a critical role in fire safety, but not all fire doors are built the same. They are rated based on their ability to resist fire for a certain period, typically FD30 (30 minutes) or FD60 (60 minutes). The rating signifies the duration the door can withstand heat before fire and smoke pass through.
Materials like timber, steel, or composite are chosen according to the building’s specific fire protection needs, with steel often used in industrial settings and timber in residential or commercial environments.
Fire doors also incorporate seals (intumescent strips) and hardware, such as fire-rated hinges and automatic closers, tailored to provide different levels of protection. These components ensure the fire door effectively contains fire and smoke, offering valuable time for evacuation and fire control.
Because of these variations in materials, seals, and fire ratings, fire doors are not standard solutions but must be carefully selected to meet the unique fire safety requirements of each building.
Answer: False
Fire doors are crucial for preventing the spread of fire and smoke, which is why they are designed to stay closed. However, in some high-traffic areas like hospitals, schools, or offices, where doors need to be kept open for ease of movement, hold-open devices are often installed.
These devices allow fire doors to remain open but automatically release and close the door when a fire alarm is activated. This maintains fire safety while offering convenience.
Manually propping fire doors open with objects is illegal, as it prevents the door from performing its safety function in an emergency. Properly installed hold-open devices are the only compliant way to keep fire doors open while ensuring their effectiveness in a fire.
Answer: True (with exceptions)
While painting a fire door is possible, it must be done with care to avoid compromising its fire-resistant components. Fire doors are equipped with intumescent strips or seals that expand when exposed to high heat, sealing the gap between the door and frame to block fire and smoke. Applying thick layers of paint, using inappropriate paints, or painting over these seals can prevent them from functioning correctly. This can significantly reduce the fire door’s effectiveness in an emergency, potentially rendering it non-compliant with fire safety regulations.
To ensure proper maintenance, it’s crucial to use fire-resistant paints and avoid covering essential components like intumescent strips. Any painting or refinishing should follow the manufacturer’s guidelines and be inspected by a certified professional to maintain the door’s fire rating and compliance with safety standards.
Answer: False
Fire doors, like all fire safety equipment, require regular inspections and maintenance to ensure they meet performance and regulatory standards. In the UK, the Regulatory Reform (Fire Safety) Order 2005 mandates that fire doors be inspected periodically for wear and tear, including damaged seals, faulty self-closing devices, gaps in the door frame, or misalignment. Neglecting regular maintenance not only puts lives at risk but also leaves building owners liable for legal penalties, as proper fire door maintenance is crucial for compliance with fire safety laws.
A proper inspection should check for the following:
By adhering to these standards, businesses ensure that their fire doors function effectively during an emergency, minimising the risks to life and property, and ensuring compliance with UK fire safety regulations.
Answer: True
Every component of a fire door, including the door frame, hinges, handles, locks, and latches, must be fire-rated to ensure the door maintains its integrity during a fire. This is because each part of the door assembly plays a crucial role in containing the fire.
Fire-rated hinges are designed to withstand high temperatures without warping, while fire-rated handles and locks ensure the door can be opened or closed even during a fire. Using non-fire-rated hardware could compromise the door’s ability to prevent fire and smoke from spreading, thus nullifying its intended protection.
The entire fire door assembly is tested as a unit to meet specific fire resistance standards, so any replacement part must also be fire-rated to ensure the door continues to function correctly. This holistic approach ensures that the door maintains its fire resistance for the rated duration, safeguarding the building’s occupants and allowing time for safe evacuation.
Answer: True
Gaps under fire doors should be kept to a minimum, typically no more than 3mm, to ensure they function effectively in containing fire and smoke. Larger gaps significantly compromise the door’s performance, allowing dangerous gases, smoke, and flames to pass through, which can hasten the spread of fire. Proper installation of a fire door includes ensuring there is an even, minimal gap around the edges and under the door. In some cases, fire-rated seals or drop-down seals are used to cover these gaps, ensuring compliance and safety.
Inadequate gaps can undermine the door’s entire fire resistance rating, which is why fire doors are carefully tested as a complete unit—including frame, door, and any gaps—to ensure that every part of the door assembly contributes to its fire protection properties.
Answer: False
Only specific intumescent seals designed for fire doors can be used when replacing seals. These seals are crucial because they expand when exposed to high temperatures, filling the gaps around the door to slow the spread of fire and smoke.
Using the wrong type of material, such as standard weatherproofing or non-fire-rated seals, can compromise the fire door’s effectiveness, making it non-compliant with fire safety regulations. Improper seals may also fail during a fire, reducing the door’s ability to protect lives and property.
Always ensure replacement seals are tested and certified for fire protection.
Answer: False
Misconceptions about fire doors often stem from a lack of understanding of their critical role in fire safety. One common myth is that all solid doors can serve as fire doors, when in fact fire doors are specially designed with fire-rated materials and seals to withstand high temperatures and block the spread of fire and smoke. Another widespread belief is that a fire door’s performance is solely dependent on the door slab itself, ignoring the essential role of certified components like hinges, frames, and handles. Such myths can lead to non-compliant installations, putting lives and property at risk.
Another misconception is that once installed, fire doors require little to no maintenance. In reality, fire doors must undergo regular inspections to ensure they function as intended. Faulty closing mechanisms, worn seals, or improper door gaps can all compromise the door’s ability to prevent fire spread. Failing to maintain them not only endangers occupants but can result in legal penalties for non-compliance.
Educating both building owners and residents is essential to dispel these myths. Building owners need to understand that fire doors are not standard doors but critical components of a building’s passive fire protection system. Regular maintenance, proper installation, and adherence to fire safety regulations are vital to ensure these doors function properly in an emergency. Similarly, residents and tenants should be informed of the importance of keeping fire doors unobstructed and in good working order, as well as the dangers of propping them open or making unauthorised modifications.
By raising awareness and providing correct information, fire safety experts can help ensure that fire doors serve their intended purpose: saving lives by preventing the rapid spread of fire and smoke.
Proper fire door installation is critical for ensuring the door’s ability to prevent fire and smoke from spreading. Key requirements include ensuring correct alignment of the door within the frame, maintaining appropriate gaps (typically 3mm around the edges), and installing certified components such as fire-rated hinges, seals, and hardware. The door must also close automatically and latch securely.
Certified professionals are essential for both installation and inspections. They ensure compliance with fire safety regulations, verify the use of fire-rated materials, and guarantee that the door has been installed correctly. Fire doors are tested as a complete assembly, and any errors during installation—such as using non-rated components or incorrect alignment—can render the door ineffective, putting lives at risk.
Engaging a certified installer or inspector not only ensures that fire doors meet regulatory standards but also helps building owners avoid legal penalties for non-compliance. It is vital to rely on experts to ensure that these life-saving barriers perform effectively in the event of a fire.
