Fire exit with step

[Guest KevinB]

Hi,
Is it possible to have a step at the final exit door from a protected stairwell. WE have app 180mm difference between the inside FFL and the external pavement. Is it permissible to incorporate a step at the door and where would we find guidance on this?

Thank you.

You will find guidance in approved document M and K and have you considered wheelchair uses, also risers have a maximum height of 150mm.
