Fire safety is a critical aspect of building planning and construction. One of the most important components in ensuring safety is the fire door. Fire door ratings are important for knowing how well these doors stop the spread of fire and smoke.. Let us dive into what fire door ratings mean and why they matter.
Fire door ratings indicate the duration a door can withstand exposure to fire. This rating is determined through rigorous testing under controlled conditions. Manufacturers must prove that their doors can resist fire for the specified time before they receive certification.These ratings are vital for ensuring that a door can perform as expected in a fire emergency.
Fire door Ratings and What They Mean
NFR: Non-fire rated
FD30: 30 minutes of fire resistance
FD60: 60 minutes of fire resistance
FD90: 90 minutes of fire resistance
FD120: 120 minutes of fire resistance
Understanding these classifications helps in selecting the right door for specific applications. Fire doors play a crucial role in passive fire protection, slowing down or stopping the spread of fire within a building.
Q-Mark Fire Door Identification Plug
So, what exactly is a Q-Mark fire door identification plug? This plug is a mark of quality assurance. Fire doors manufactured under the BM TRADA Q-Mark Fire Door Manufacturers scheme feature these plugs. Builders and owners use them as a visual way to confirm that a door is certified and meets stringent fire safety standards.
What Does the Plug Show?
Each Q-Mark plug consists of two sections:
• Outer circle: Indicates the fire resistance period (in minutes).
• Inner tree: Represents the door’s manufacturing status.
The plug also includes a unique certified company number, adding another layer of verification.
Here’s what the outer circle colours mean:
• Yellow: FD30 – 30 minutes of fire integrity.
• Blue: FD60 – 60 minutes of fire integrity.
• Brown: FD90 (complete doorsets only) – 90 minutes of fire integrity.
• Black: FD120 (complete doorsets only) – 120 minutes of fire integrity.
And the inner tree colours:
• Silver: Complete doorset – Q-Mark certified for fire only.
• Red: Approved door leaf/frame (FD30 and FD60 only), without intumescent strips.
• Green: Approved door leaf/frame (FD30 and FD60 only), with intumescent strips.
• Orange: Approved factory-fitted glazing.
• Gold: Certified installation of a complete factory-hung doorset.
These identification plugs help ensure that the fire doors are of high quality and meet safety standards.
To illustrate, let’s consider a fire-rated door with an FD30 rating. This door can withstand fire and smoke for at least 30 minutes when correctly installed. The outer yellow circle on the Q-Mark plugs confirms this rating. The top plug may have a red inner leaf/tree, which means intumescent strips are not supplied. A silver inner tree could signify it is a factory-hung doorset. Finally, a gold inner tree might indicate that a certified installer installed the door.
Why is it Important to Understand Fire Door Ratings
Fire doors are essential in the fire safety strategy of any building. They help control the spread of fire and smoke, allowing occupants time to evacuate safely.
Fire doors such as FD30 and FD60 are commonly used in various settings. An FD30-rated door provides 30 minutes of protection, and an FD60-rated door offers 60 minutes. The choice between the two often depends on the building's layout, use, and fire risk assessment.
Example:
Escape routes: FD30 doors are often sufficient.
High-risk areas: may require FD60 doors for extra protection, such as hospitals, schools, or commercial buildings.
Critical areas: FD120 doors work well in mechanical and electrical rooms. They are also good for storage areas with flammable materials and high-rise buildings.
A fire risk assessment is essential to determine the appropriate rating for each door in a building.
The diagram above shows how FD30 fire doors act as fire and smoke barriers in apartments. Each unit has a fire door that slows down the spread of fire to the hallway. Extra doors help separate the hallway from the staircase. This setup offers a total of sixty minutes of fire protection. It provides thirty minutes for the hallway and thirty minutes for the entry near the staircase.
What Does The ‘s’ Mean on a Fire Door Rating?
In assessing fire doors, the 's' following the rating (such as FD30s or FD60s) signifies the door's ability to also hinder the propagation of cold smoke. These doors are outfitted with smoke brushes and intumescent strips, augmenting their defensive attributes.
Legal Responsibilities and Maintenance
Fire door ratings also play a role in compliance with building regulations. New buildings must follow safety standards that include fire doors. The rules differ by location but usually require fire doors. These doors help ensure safe exits in case of a fire.
Building owners have a legal responsibility to maintain fire doors and ensure they are functioning correctly. Regular inspections and maintenance are necessary to uphold fire ratings. If someone does not install or maintain a fire door properly, they may compromise its protective qualities.
Compliance with Building Regulations
Fire door ratings are vital for meeting building regulations. In England and Wales, Building Regulations Approved Document B gives guidance on fire-resisting doors. It refers to British and European standards for fire resistance and smoke control.
For existing buildings, the Regulatory Reform (Fire Safety) Order 2005 mandates that fire doors be maintained in good condition, with the “Responsible Person” ensuring regular inspections. These requirements apply to public spaces and common areas, excluding private homes.

How to Find a Fire Door Rating
To find out the rating of your fire door, look for a certification label. This label usually indicates the door's rating and compliance with safety standards. If you are unsure, consulting a fire safety guide or professional can provide clarity.
Fire door ratings represent a lifeline in an emergency. Properly rated and maintained fire doors can save lives and protect property. Choosing the right fire door rating is essential in any building's fire strategy.
In Summary
Understanding fire door ratings is crucial for ensuring safety in any structure. If you are a builder, property owner, or tenant, knowing these ratings can help you make smart choices about fire safety. Always prioritise the installation of certified fire doors and adhere to regulations to protect lives and property from fire hazards.
When you invest in quality fire doors and know their ratings, you help create a safer environment for everyone. Remember, if there is a fire, every minute counts, and fire door ratings can make all the difference.
