How to Specify Fire Doors for Hospital Corridors
Hospital corridors produce the densest door traffic in any building type. Five specification decisions decide whether the doors survive the first two years: leaf construction, closing force, vision, sealing, and the hardware schedule.
A ward corridor is the hardest working door line in a hospital. Beds, trolleys, wheelchairs, cleaning machines and staff on the run all pass the same opening, and the leaf is expected to hold a fire compartment for the life of the building. Most hospital door failures in the first two years are not fire failures at all — they are finish, hardware and adjustment failures. Five decisions, taken at specification stage, decide most of the outcome.
1. Leaf construction: what the abuse actually is
The damage pattern in a hospital corridor is edge impact, not abrasion. Bed frames and trolley corners hit the leaf at roughly the same height, several hundred times a day. Thin-skin steel leaves dent at the lock edge and the leading edge; the dents then hold cleaning fluid and start to corrode.
A steel leaf with a heavier skin, a full-length stiffener and a stainless or PVC kick plate at the bottom handles this pattern. Timber-faced leaves look better in a private ward and worse in an acute corridor, where the impact is concentrated and the cleaning is aggressive.
2. Closing force: the setting nobody documents
A closer sized for an adult office door will hit a patient on a walking frame. A closer turned down until it no longer reliably latches leaves the compartment open. The correct setting is the lightest force that still latches from a standing start, and it needs to be recorded — because the next person to adjust it will otherwise turn it up.
Ask the supplier to state the closer model and its adjustable range, and require the commissioned setting to be written on the door schedule. This is a five-minute item at handover that prevents years of propped-open doors.
3. Vision: at whose height
A vision panel serves two purposes that get confused. For staff, it is a supervision window: see the patient before entering. For a patient being moved on a bed, it is a sense of orientation. Panels set at staff eye height fail the second purpose entirely.
Where the corridor serves paediatrics, geriatrics or mental health, add a second lower panel or specify a full-height glazed strip. Remember that fire-rated glazing is a system, not a pane: the glazing, the beading and the aperture in the leaf are part of the tested assembly. Substituting a plain tempered pane voids the rating of the whole door.
4. Sealing: smoke, not just fire
Hospitals are smoke-compartmented as well as fire-compartmented. Corridor doors on a ward floor are usually smoke doors as well, which means the specification needs a smoke leakage figure and a seal that survives being cleaned. Intumescent strips alone do not address cold smoke; a combined intumescent and cold-smoke seal does.
Seals are also the first component to be destroyed by chlorine-based disinfectants. Specify the seal material against the actual cleaning agent, and put the replacement interval in the maintenance file rather than leaving it to habit.
5. Hardware schedule: the document that decides the outcome
Every door in a hospital is a small system: closer, hold-open or free-swing, latch, lever, cylinder, door stop, kick plate, signage, and sometimes an access-control reader and a bed-head interface. When these come from four vendors and are assembled on site, the failures appear in the second year, one component at a time.
Supply the hardware as a matched set with the leaf. Then keep one schedule per floor, listing door ID, leaf size, fire and smoke rating, closer model and setting, hardware set, and the test evidence reference. Commissioning inspections are done leaf by leaf, and a schedule that matches the doors is the difference between a one-day sign-off and a two-week argument.
A note on ratings and documentation
This article deliberately does not state which rating a hospital corridor needs. That depends on the compartment it sits in, the national code, and the smoke strategy — three things only the project's fire consultant can settle. What a supplier can do is supply the evidence chain: the test report for the assembly, the classification, the installation instruction, and the marking. Ask for those four, and ask that they match the door you are being quoted.
