Domestic Exit Door from a Protected Lobby

[Steve AU]

Just wanted to check, where the front door of a property is the exit point for a three storey protected stairwell, is it a requirement that the door opens to a full 90 degrees?

I would imagine all doors will open to a least 90 degrees, why can't this door, also it is an escape door therefore if it can't then this will reduce the numbers that can use it.

Thanks Tom, just checking if there is a defined documented fire requirement that states that an escape door MUST open to 90 degrees minimum?

 

Cheers

I am not aware of any fire safety document that indicate this, in so precise terms but Approved Document M requires principal communal entrances to be a certain full width which you would not be able to achieve if the door did not open the full 90 degrees.
