These “emergency exit devices” conform to BS EN 179 instead, and are generally not suitable as more force is needed to operate them, i.e. There’s an alternative type of a smaller push pad or lever, which seems to be mistakenly put onto doors for use by the public. The relevant standard is BS EN 1125 - “Panic exit devices operated by a horizontal bar”. These fittings are long horizontal bars or pads which operate by body pressure. If there are more than 60 persons likely to use an exit, and that group includes those unfamiliar with the building, a degree of panic must be assumed. In buildings used by the general public, the usual hardware on final exits is a horizontal push pad or bar, unless the door is completely free-moving, such as the front door (once unlocked).įor this category of occupant, doors need to be operated easily and obviously. Turn knob, single bolt, or other simply operated, single device.Emergency exit devices (the smaller pads and levers).Security fittings on fire doors should be thought of as a hierarchy: Official guidance to the RRO (from the Communities and Local Government department) recommends that that all doors on escape routes should open in the direction of escape, but states that this is particularly important if more than 60 people use them or they provide an exit from a high fire risk area. The need for outward opening fire exit doors ![]() The RRO only applies to England and Wales, although other regions of the UK have different legislation with a similar outcome. In the Regulatory Reform (Fire Safety) Order 2005 (RRO)*, article 14 covers “Emergency Routes and Exits,” and states that, “In the event of danger, it must be possible for persons to evacuate the premises as quickly and safely as possible”.ĭepending on circumstances, this normally involves emergency doors opening in the direction of escape, no sliding or revolving doors used as emergency exits, and emergency doors not being locked or fastened in a manner that they cannot be easily and immediately opened. What can you have, where, and who says so?įurther reading: How Many Fire Exits Are Required in a Building? and as you may suspect, there are hidden rules about it. After all, there are quite a few different options - push pads, glass bolts, turn knobs, etc. When fitting strips and seals they must not be altered in shape or size, as this will reduce their effectiveness.They should be tested to BS 476 part 22 and part 31.1 or EN 1634-3.Are you wondering what hardware you should fit to your emergency fire exit doors? Where a door is also required to have a smoke seal, the best solution is to use a combined brush or rubber blade seal.Īt no time should the strips be overpainted as this causes them to harden and lose their ability to perform. They must be applied to both vertical edges and the top, but are not required along the bottom edge. They may be fitted either in the door frame or the door edges. At around 200° C this will expand to fill the gap between the door and the frame thus maintaining its integrity. The solution is to use a strip of intumescent material, set into either the door edges or the frame opposite the edges. This is because the pressure of a developing fire drives hot gases between the door and frame, leading to loss of integrity. Door edges are the part of a door set most susceptible to penetration by heat and smoke.
