RR Fire Safety Order 2005

The following guide can be used to determine the general capacities of escape routes:
A width of at least 750mm can accommodate
up to:
• 80 people in higher risk premises;
• 100 people in normal risk premises; or
• 120 people in lower risk premises.
A width of at least 1,050mm can accommodate
up to:
• 160 people in higher risk premises;
• 200 people in normal risk premises; or
• 240 people in lower risk premises.
An additional 75mm should be allowed for each additional 15 persons (or part of 15).
The minimum width of an escape route should
not be less than 750mm (unless it is for use by less than five people in part of your premises)
and, where wheelchair users are likely to use it, 900mm.
The aggregate width of all the escape routes should be not less than that required to accommodate the maximum number of people likely to use them.

May help in setting out your arguments
