Fire Door Myths

Fire safety is a critical aspect of building design and maintenance. Yet, there are numerous myths surrounding fire doors that can lead to dangerous missteps. This article aims to bust the most persistent fire door myths and replace them with accurate, practical guidance. If you work in facilities management, construction, or building safety, understanding these truths can help you maintain compliant, effective fire protection. Throughout this post we’ll repeatedly reference and optimize the supplied keyword phrase fire door myths to ensure clarity and consistency.

Introduction: Why Fire Door Myths Matter

Fire doors are a key component of passive fire protection. They help curb the spread of smoke and flames, protecting occupants and providing safer egress during emergencies. However, misinformed beliefs about what makes a door “fire rated” can result in unsafe alterations, improper maintenance, or non-compliance with standards. By separating fact from fiction, building managers can avoid costly mistakes and legal risk while preserving the integrity of the fire safety system.

In this overview, we’ll cover a range of common misconceptions, from door modifications to glazing, hardware, gaps, and governance around fire risk assessments. We’ll also touch on real-world responsibilities, including who is accountable for fire risk management and what professionals to call for guidance. Let’s separate the myths from the truths.

Myth 1: Standard doors can be turned into fire doors by using larger doorstops on the existing frame

• The truth: Additional doorstops will not turn a standard door into a fire door.
• Why it matters: Fire doors are designed and tested as complete assemblies, including the door leaf, frame, seals, hinges, and hardware. Simply adding doorstops does not restore or guarantee fire resistance, and it can create gaps or interference that compromise the door’s certification.
• Practical takeaway: Do not attempt to retrofit a non-fire door with hardware or doorstops in an effort to achieve fire protection. If a true fire door is required, specify and install an appropriately certified fire door assembly, with proper inspection and maintenance.

Myth 2: Painting any door with fire retardant paint makes it a fire door

• The truth: Fire retardant paint does not transform a door into a recognised fire door.
• Why it matters: Certification is based on the entire door assembly, not just paint. A door that has been treated or painted with retardant coatings may still lack the tested performance of a true fire door, and would not be recognized as such in compliance checks.
• Practical takeaway: If you need a fire door, source a door that has been tested and certified as a fire door, with appropriate labeling and installation. Do not rely on paint alone to achieve fire resistance.

Myth 3: Any lock can be put onto a fire door because it’s made of metal, which doesn’t burn in a fire

• The truth: You can only fit fire-tested, compatible locks, as removal of too much material from the door can impact its performance in a fire.
• Why it matters: The hinges, locking hardware, and door edge components are part of a certified system. Inappropriate locks or modifications can compromise the door’s integrity, its fire rating, and egress performance.
• Practical takeaway: Use locks and hardware that are approved for fire doors and follow the manufacturer’s guidance and local fire safety regulations. If unsure, consult a qualified fire safety professional.

Myth 4: A big fire door can be cut down to fit

• The truth: A fire door may only be trimmed by a certain amount; resizing outside those limits invalidates its certification.
• Why it matters: Cutting or resizing a fire door can alter its thickeness, edge conditions, and overall performance, undermining the tested fire rating.
• Practical takeaway: Do not resize fire doors beyond the specified allowances. If you require a different width or height, replace with a certified door of the correct size rather than altering an existing door.

Myth 5: The gap between a fire door and its frame doesn’t matter

• The truth: The size of the gap around the perimeter of the door is critical to stopping the passage of toxic fumes and smoke. For doors with smoke seals, this gap is usually around 3mm.
• Why it matters: Proper clearances ensure seals function correctly, preventing smoke and hot gases from bypassing the door. An oversized gap can render the door ineffective in an emergency.
• Practical takeaway: Maintain manufacturer-specified gap tolerances. Regular inspections should check that seals are intact and that gaps remain within the allowed range.

Myth 6: You can fit your own glazed panels in a fire door

• The truth: To make a fire door with a glazed panel requires the correct components and should only be attempted by a trained person. Cutting holes in fire doors invalidates their fire door certification.
• Why it matters: Glass and frame configurations must be tested as part of the door assembly. Improper glazing can compromise fire resistance and safety.
• Practical takeaway: If glazing is needed, use an approved fire-rated glazed insert and have it installed by qualified personnel. Do not modify the door to accommodate non-certified glazing.

Myth 7: Fire doors have to be checked by the fire brigade

• The truth: Since October 2006, the responsible person’s duty is to carry out all fire risk assessments. The fire service does not carry them out.
• Why it matters: Responsibility for fire risk assessment sits with the building owner or appointed responsible person. This ensures ongoing compliance and risk management, rather than relying on emergency responders for safety audits.
• Practical takeaway: Ensure your organization designates a responsible person or fire safety officer to conduct regular risk assessments and coordinate corrective actions.

Myth 8: I have a fire risk assessment, so I cannot be prosecuted

• The truth: Simply having a fire risk assessment doesn’t make you compliant. It is a tool to identify and measure risk, not a guarantee of safety or legal compliance.
• Why it matters: Compliance involves implementing recommendations, maintaining equipment, training staff, and re-evaluating risks over time.
• Practical takeaway: Treat fire risk assessments as living documents. Act on findings, document remedial actions, and schedule follow-up reviews to maintain a safe environment.

Fire door myths can lead to dangerous shortcuts that undermine safety and compliance. By understanding the truths behind common beliefs, you can avoid common pitfalls and ensure your building’s fire protection remains robust. Remember to rely on certified fire door assemblies, qualified professionals, and formal risk assessments to guide your decisions.
