I’m currently completing a fire risk assessment for a workshop and trying to find out what the minimum distance is from one point, to an exit point, “or an open space”, which I think is how it is quoted.
Any help welcome

Hello David,
The travel distance to storey exits we use on our risk assessments are as follows.
One direction only to exit Shops,offices,warehouses (18m) Industrial (25m).
More than one direction to exits Shops (30m)offices,warehouses,Industrial (45m).
Hope this is of some help to you regards graeme.

I trust that you mean maximum distances. If so graeme's figures are about OK providing you don't recognise a High Fire Risk for the area. If so the travel for a dead end comes down to about 10m and the others can be roughly halved.

Take a look at Table 3 of Approved Document B1 to the Building Regulations - which whilst applicable to new-build may be taken as providing guidance for existing buildings.
Eg: Maximum Travel Distances
Offices 1 direction: 18m More than 1: 45m
Shop & Commercial 1 dir: 18m More: 45m
Industrial/storage 1 dir: 25m More: 45m
Special fire hazard 1 dir: 9m More: 18m
etc.
There are other examples and it is notable that direct distance is taken as 2/3 travel distance when internal layout is unknown.
