Please some advise:
I am doing a H&S risk assessment for a site and want to mark a few way-points on the estate maps AND write down their map reference - what system is preferred by the emergency services (OS Map reference? Latitude/Longitude? Other?)
A bad experience last year (Where a road ambulance couldn't find a 'viewpoint' on a named road marked on OS maps) makes me ask this question, and I do not seem to be able to get a sensible reply from those who should know.
