BS EN 179 – Emergency exit devices
This standard covers devices to be used in emergency situations where people are familiar with the emergency exit and its hardware. Because of this, a panic situation is most unlikely to develop. Devices operated by a lever handle or push pad may therefore be used.
SCOPE – BS EN 179
The main purpose of the performance requirements of this standard is to give safe and effective escape through a doorway with one single operation to release the device. However, escape can require prior knowledge of the operation of the device. This is consequently considered suitable for locked doors on escape routes only where panic situations are not foreseen.
