Your obligation as an employer is to keep your employees working in and outside your premises safe - this includes individuals working by themself. Whilst they may be at less risk of harm from their peers, there are health and safety risks associated with lone working that are exclusive to workers' isolation and thus need to be regularly assessed and controlled.
Most of the time, lone workers face the same hazards at work as anyone else, but what increases the risk of harm is that they may not have anyone to help or support them if and when things go wrong. This is why a lone worker risk assessment is vital, along with training, supervision, monitoring and support.
