Posted By Raymond Rapp Jason If lone working cannot be avoided for whatever reasons, then you can only do what is reasonably practical and reduce risks to ALARP. Giving them a means for communication such as a mobile phone is one control, getting them to call in periodically to someone may be another. Making sure that security is good and perhaps a remote CCTV might be practicable. Finally, ensure there are adequate first aid provisions and maybe train them up as first aiders. Ray

Posted By Descarte The sensors you mention, are you refering to motion detection sensor like security lights have or a personal alarm device? IMO a personal alarm device which initialy gives the wearer a warning and then pages an external responisble person.( Manager, security etc. ) when they have become immobile or lay horizontal for over 1min. If they cannot contact the IP via perhaps a personnaly held mobile phone, site phone, or other means you can escalate this to presuming man down. Response again could be via manager, security or 3rd party, surely there are adjacent businesses, an agreement, as long as there are few false calls could be set up if they have a specific procedure to follow, places to check, before contacting emergency services. Of course this could be complicated by site specific risks, asphyxiation, toxic gas, electricity, dangerous machinery which any responder should be made aware of. Des
