Posted By Ged Hi Rob, The guidelines given in Fire precautions (workplace) regs 1997 as amended 1999 Give maximum travel distances to a place of safety if only one exit and it is a low fire risk area 45 Metres more than one exit available 60metres Normal risk production areas factory only more than one route 45m single route 25m High fire risk More than one route 25m single route 12m These are guidelines only and should be used with caution. You must look at each part of the workplace and decide how quickly persons would react to a fire alert. Where the distances cannot be provided you will be required to provide extra fire precautions and should consult your local fire safety officer..(once you have completed your fire risk assessment)
