Every Component Matters
HINGES
Hinges have an important role in ensuring the integrity of a fire door. Fire door hinges must remain adequately attached. CE marks ensure hinges are manufactured to British standard BS EN 1935: 2002, whilst the correct installation & maintenance of these hinges are vital to the integrity of a fire door set/assembly.
INTUMESCENT / SMOKE SEALS
Smoke inhalation kills in just a few minutes and also quickly obscures vision, creating disorientation that can prevent a safe escape. A victim may be rendered unconscious very quickly, leading to rapid death. An intumescent seal is a strip of intumescent material encased in a rigid casing, that when exposed to heat, expands, closing any gaps around the door to stop the fire & smoke spreading for a period of time. A separate seal is sometimes incorporated into the frame or combined with an intumescent seal to provide ambient temperature or ‘cold’ smoke sealing which restricts the issuance of smoke prior to the intumescent seals reaching the temperature at which they expand.
GLAZED APERTURES
Commonly used in communal door sets, Glazed apertures provide added safety in everyday use and in the event of a fire they aid detection of fire and smoke, whilst providing visibility to potential escape routes. Doors should only be glazed in accordance with the door manufacturers test evidence and the glass should be permanently marked as a minimum with the glass name, glass suppliers name and the applicable glass performance classification.
DOOR & FRAME GAPS
Ensuring the correct gaps between door and frame & Threshold gaps which is the gap between door and FFL (finished floor level) are vital in the performance of a fire door set being signed off for fit purpose of use. Ensuring gaps between door and frame are no bigger than 4mm and that threshold are no bigger than 8mm or else, in accordance with the door manufacturers tested evidence, is vital to the fire door performance.
A Structured Approach To Fire Safety Compliance
DAMAGE FREE & LABELLED
With the door leaf being the main component of a fire door set, it is vital there is traceability back to the manufacturer, a certificated door set will have either a label or plug which relates to its individual certification and fire testing report. Should damage be present to the door leaf in which a replacement will be required, this will assist the client in keeping costs down with only having to replace the door leaf instead of the whole door set providing the frame remains in accordance wth the door leaf manufacturers test evidence.
OPERATING FURNITURE
For many ironmongery items you will need to ensure that only marked products are used on all fire doors and escape doors, just like hinges this comes in the way of a CE marked item which falls in line with the relevant British standard. The correct installation and maintenance of these items are necessary for the door set to be approved.
