The importance of keeping fire doors shut is to prevent the spread of fire and
smoke cannot be overstated. This will give people vital seconds needed to
leave the building, particularly in the early stages of a fire.

the smoke seals fitted to fire doors must also be in good repair. Otherwise this
may allow fire and smoke to spread quickly into the escape route and prevent
other people from using the route.
