Fire doors are specially designed to hold back fire and smoke, giving people time to escape and giving firefighters time to reach the fire. Without them, fire spreads rapidly through corridors, stairwells, and open-plan areas — turning a small incident into a building-wide emergency.
They work by:
Containing fire — slowing the spread from one area to another
Stopping smoke movement — preventing toxic smoke from filling escape routes
Protecting escape routes — keeping corridors and staircases usable for longer
Maintaining compartmentation — ensuring the building performs as designed in a fire
A fire door only works if it’s closed, compliant, and in good condition.
Under the Regulatory Reform (Fire Safety) Order 2005, businesses must ensure fire doors:
Are kept closed and never wedged open
Are regularly inspected
Have working self-closers
Have intact seals and hinges
Failing to maintain fire doors is one of the most common — and most serious — breaches found during fire safety audits.
In a real fire, every minute counts. A certified fire door can provide 30 to 60 minutes of protection, depending on its rating. That extra time:
allows safe evacuation
protects vulnerable occupants
slows fire growth
reduces property damage
supports firefighting operations
Without a functioning fire door, fire can spread through a building in under three minutes.
Most failures come from simple, avoidable problems:
Wedged-open doors
Damaged seals
Broken or removed self-closers
Gaps around the door
Untrained staff
A fire door that doesn’t close properly is not a fire door — it’s just a door.
Maintaining fire doors shows professionalism and protects:
your staff
your customers
your reputation
your legal compliance
your building
It’s one of the simplest, most effective ways to reduce risk.
