Fire Exit Hardware
It is desirable that doors at final exits in public buildings, places of entertainment, shops etc. should be fitted with panic devices operated by a horizontal push bar or touch bar. The emphasis for products covered by this standard is on safe exit rather than security.
The main purpose of the performance requirements of this standard is to give safe and effective escape through a doorway with minimum effort and without prior knowledge of the device i.e. for locked doors on escape routes where panic situations can be foreseen.
