A lone worker (LW) is someone who performs an activity in isolation from other workers. With no-one to assist them a risk assessment may be required. Lone working can now be supported by cloud-based monitoring systems and monitoring call centres. In the United Kingdom they are called Alarm Receiving Centres or ARCs , or Emergency Dispatch Centers or EDCs in the USA.

They should not, though, be more at risk than other people. It will often be safe to work alone. However, employers must think about any health and safety risks before people are allowed to do so. Things you need to consider include: assessing risk areas, including violence manual handling the medical suitability of the individual does the workplace itself present a risk? training requirements levels of experience how best to monitor / supervise having systems to keep in touch
