Riser doors

[Mr Burns]

Hi all,

I was looking at a number of fire doors in a builing that was built in the 80s and have origional doors, the riser doos have 4no rim budget locks openable by a square key one in each corner, no hinges or handles are fitted so the door will just fall open when rim locks ae unlocked, no intumescet strips or smoke seals are fitted to door or fame either, am I right t advise these doors are replaced? my thoughts were that the means of escape would be compromised by smoke escaping the holes in the door from the rim locks even if smoke seals are fitted.

 

any advice welcome

thanks

Is there any fire separation at floor level in the riser and does the riser meet a half hour standard excluding the smoke problem.

Hi Tom,

No, there is no fire seperation between floors, walls surrounding the mechanical risers are blockwork and the doors are 44mm

Thanks again for your help

Mr B
