Editing Crash bar (section)

=== On automatic doors ===
In some jurisdictions, when [[Automatic door|automatic doors]] are used on the primary exit route, these doors are equipped with crash bars. In the event the automatic door does not function, it becomes an outward swinging rather than sliding door. Crash bars are one of many emergency release mechanisms that can be used with automatic doors. Depending on available space, a common alternative is to install an emergency exit door beside the automatic doors. Installation of a secondary crash bar equipped exit is often required in large buildings with revolving doors, since these are too slow for a crowd to move through.
