Should Fire Doors Be Wedged Open? Absolutely not unless it is done properly using methods that will be mentioned in this blog. Wedging fire doors open poses a serious safety risk, allowing fire and smoke to spread rapidly, endangering lives and property. While some may prop doors open for convenience, doing so is dangerous and often illegal under UK fire safety laws. Propping doors open can also invalidate insurance and lead to legal and financial penalties. Safe alternatives include acoustic or magnetic fire door retainers and free-swing overhead door closers.
In the UK, fire doors require inspection at least every six months, as specified in BS 9999. For high-traffic environments like schools, hospitals, and similar facilities, it’s smart to conduct checks even more frequently. This isn’t just about satisfying compliance; catching damage or issues early can prevent bigger headaches later.
What are fire doors made of? They are built with strong materials like solid wood, gypsum, or steel that can handle high heat. Heat-activated seals around the edges expand in a fire to block gaps. Some fire doors also have special glass that stays strong in heat. The outside can be finished with wood veneer, paint, or laminates, just as long as they meet fire safety rules.
Landlords need to install, inspect, and maintain compliant fire doors under the Regulatory Reform (Fire Safety) Order 2005 and Building Regulations. Tenants need to use the fire doors as intended and report any issues promptly, but they’re not authorized to make changes or replacements themselves.
Most internal fire doors in the UK are 1981 x 762mm (2'6") or 1981 x 838mm (2'9"), 44mm thick for FD30 and 54mm for FD60. Metric doors are 2040mm tall and 726mm or 826mm wide. If someone in a wheelchair uses the door, Approved Document M accepts an 826mm leaf, and an 838mm leaf clears it too. Once the door is hung, the gap to the frame should never be more than 4mm at the top and sides. And the rating comes from the certification label on the top edge, not from the thickness.
Fire doors prevent fire and smoke to a specific area, preventing them from spreading throughout the premises. This containment is vital, as it preserves escape routes and provides occupants with extra time to evacuate safely. In addition to protecting people, fire doors help minimise property damage and ensure that the building remains compliant with current fire safety regulations.
Hollow core doors are lightweight, cost-effective, and ideal for interior use in low-cost projects, but offer poor insulation, soundproofing, and security. Semi-solid core doors, with a foam core wrapped in MDF or plywood, provide a better balance of cost, durability, insulation, and soundproofing, making them suitable for residential and commercial spaces. Solid core doors, the most expensive and heavy option, offer superior security, durability, insulation, and soundproofing, making them the best choice for high-traffic areas and locations requiring high security and privacy.
Do fire doors need to be self closing? Self-closing fire doors are crucial for building safety, automatically preventing fire and smoke spread. Legally required in UK escape routes, corridors, and staircases, they use closers meeting BS EN 1155 or BS 5839: Part 3, with hydraulic or gear mechanisms for smooth closure. Some closers hold doors open until a fire alarm triggers closure. They offer fire containment, increased escape time, legal compliance, and durability. Crucially, they must never be propped open.
Identifying a fire door requires multiple key steps. First, search for a certification label, which is usually positioned on the upper edge of the door. Next, ensure that the gap between the door and its frame is no more than 4mm. Make the door equipped with intumescent seals, which expand when exposed to heat. Check for at least three secure hinges and a fully functional self-closing mechanism. Finally, in commercial settings, look for proper fire door signage.
Different types of fire doors are available based on various factors such as their fire resistance (FD30-FD120, higher ratings for higher-risk areas), materials (steel, wood, glass), finishes (pre-finished, unfinished, primed), style (single or double), and closing mechanisms (self-closing, automatic, power-operated). You should choose the right door depending on the building’s fire safety needs.
