These are from Fire Safety - An Employer's Guide. Link at bottom.
There should be enough available exits, of adequate width, from every room, storey or building. The adequacy of the escape routes and doors can be assessed on the basis that:
a doorway of no less than 750 millimetres in width is suitable for up to 40 people per minute (where doors are likely to be used by wheelchair users the doorway should be at least 800 millimetres wide); and
a doorway of no less than 1 metre in width is suitable for up to 80 people per minute.
Where more than 80 people per minute are expected to use a door, the minimum doorway width should be increased by 75 millimetres for each additional group of 15 people
Corridors should generally be about 1 metre wide, although wheelchair users will need a width of 1.2 metres. The doors should be aligned with the walls of the rooms so that the floor area is effectively divided into two or more parts. To avoid having to travel long distances in corridors affected by smoke, those corridors which are more than 30 metres long (45 metres in offices and factories) should be subdivided into approximately equal parts by providing, close-fitting, self-closing fire doors.

Hi Nina
There should be enough available exits, of adequate width, from every room, storey, or building. The adequacy of the escape routes and doors can be assessed on the basis that:
a doorway of no less than 750 millimetres in width is suitable for up to 40 people per minute (where doors are likely to be used by wheelchair users the doorway should be at least 800 millimetres wide)
a doorway of no less than 1 metre in width is suitable for up to 80 people per minute.
Where more than 80 people per minute are expected to use a door, the minimum doorway width should be increased by 75 millimetres for each additional group of 15 people.
For the purposes of calculating whether the existing doorways are suitable for the numbers using them, you should assume that the largest exit door from any part of the workplace may be unavailable for use. This means that the remaining doorways should be capable of providing a satisfactory means of escape for everyone present.
Hope this helps.
