Requirement for secondary external fire escape stairs from first floor flat?

[vboyle1649]

Hello
I live in the ground floor flat, my neighbour and fellow share-of-freeholder lives in the first floor flat.  The first floor flat has a large set of fire escape stairs into my patio garden.
We are going to extend our flat into the patio garden.
Our neighbours own the fire escape, but we would like to propose that the design / build of the fire escape is changed. Are there rules about the construction of the escape - can we make it slightly steeper for example?  I really have tried to find out, but the planning portal document will not load.
Thank you very much in advance!

PS I think it is not necessary in law to have a second external fire escape from a two storey building separated into flats, but as they own it I cannot do anything about that!

V. If you are proposing to make changes to the fire escape you should go through building control. Stairways have to comply with Building Regs.
Can you open this? http://www.planningportal.gov.uk/uploads/br/BR_PDF_AD_K_2010.pdf
And yes there may be no requirement for the fire escape.

Thanks very much.
No I can't - in chrome the page stays grey and in explorer it says the file is broken and cannot be fixed.
Could be because I am on a work computer.....will check.
Thanks again.
