Hi im a health and safety officer at work and im a bit confused about the pushbar fire exit rules. I know they can be left open for ventilation purposes but i need to know if the door is open can and are you aload to use that door as an entry door which leads onto a marked walkway? Thanks for any info u can share.

A push bar fire exit door is simple a final exit door fitted with a panic bar which should be only required in certain situations. Using it as an entrance/exit  door is not practical because most panic bars can only be opened from the inside. So consequently is usually used as an exit door but if it can be opened from the outside there is no reasons, that I am aware of it could be used as an exit/entrance door.
