Escape Route Capacity


Recommended Posts

Help as for the love of looking i cant find and answer to this?!

A pub has a LG bar area with 5 exits, three are close to one another and have to be discounted, the remaining two lead to a single protected stairwell, each door has the capacity for 100 as opens outwards and are 800mm each.  The shared escape stairwell is 830mm and am concious of bottlenecking as in  theory the doors combined allow a total of 200 people, do i use the calculation of just 100 people on the same grounds as a door width capacity or is there an alternative calculation?

Any help greatly appreciated.

I am not aware of any alternative calculations and your calculations appear to be correct but trying to imagine the layout is difficult and without a full survey or detailed plans it is impossible to give you a definitive answer.
