Lone working presents risks that require planning and precautions. It is defined as working without close supervision, and includes those in fixed workplaces alone, mobile workers, and people working outside normal hours. Risks include tasks requiring more than one person, emergencies where assistance is needed, and potential assaults from clients. However, lone working can also have benefits like fewer distractions. Safety involves assessing the person, location, tasks, tools, and foreseeable problems to ensure all aspects are suitable to do alone. Precautions include telling someone your plans and contact details in case of an emergency.
