FIRE & LIFE SAFETY GUIDANCE FOR FIRE DOORS & ESCAPE DOORS

Code of Practice: Hardware for Fire and Escape Doors 

Fire compartmentation doors are crucial to a building’s passive fire protection system. They resist the spread of fire and smoke and help to protect escape routes. In the event of a fire, fire doors must close and are typically equipped with self-closing devices, such as LCN overhead closers. If self-closing devices are not in place, fire doors must be locked. Clear signage should indicate the purpose and required status of these doors. Doors locked shut must not obstruct escape routes and are usually doors to cupboards, store rooms, or similar spaces.

Escape doors provide safe, unhindered egress from buildings in an emergency. Escape doors are not always fire compartmentation doors. Where this is the case, they should not be referred to as fire doors but as escape or emergency exit doors.  All escape doors, irrespective of location or desired security levels, must be ‘free from fixings’ – i.e., easily openable by all persons without a key. Planned maintenance routines are essential to ensure the safe operation of fire compartmentation and escape route doors.

MINIMUM REQUIREMENTS FOR FIRE AND SMOKE-RESISTING DOORS

Evidence of Performance

• Fire and smoke-resisting doors & frames must have evidence to demonstrate they resist the spread of fire and smoke according to the following test standards:
• Fire resistance: - either BS 476-22 or EN 1634-1; the integrity performance is stated as a period of minutes, which must be at least equal to the figure demanded by the relevant regulation (see below).
• Smoke leakage: - either BS 476-31.1 or EN 1634-3.

Evidence may take the form of:

• A single test report (in which case the evidence relates only to the configuration tested);
• An assessment by a fire test laboratory based on a range of test reports;
• Third-party certification, based on product sampling, testing and auditing of the manufacturing process.

The evidence of testing must apply to the installed door and frame assembly, as even minor differences can impact performance. Proper installation and maintenance are crucial to ensure that doors and frames function as required.

Fire compartmentation doors must be self-closing unless locked shut when not in use. Self-closing for a hinged or pivoted door means the door can close into the frame from any angle.

MINIMUM REQUIREMENTS FOR ESCAPE DOORS

Doors on escape routes must be free from fixings – usually in the direction of escape.  Escape doors may be fitted with exit devices incorporating latches or bolts. Exit devices must be operable (without using a key), usually in the direction of escape, and without needing more than one mechanism to be manipulated. Doors opening against the direction of escape may be permitted where occupancy is low, and users are familiar with the hardware providing escape. Certain alternative door types, such as automated, sliding, and revolving, will require specific features not covered here.
