Hi, In my experience the use of family members to raise the alarm if the lone worker does not return home is just one of a number of possible controls and I would consider it to be perfectly acceptable. Really its down to your risk assessment which should indicate whether the work can be done safely by a lone worker and what arrangements are necessary to ensure the lone worker is at no more risk than other employees. The following links might help especially the Suzy Lamplugh ones: http://www.hse.gov.uk/pubns/indg73.pdf http://www.suzylamplugh.org/personal-safety/ http://www.suzylamplugh....a_lone_worker_system.pdf Regards Steve
