A lone worker faces risks associated with interaction with other people, health conditions, the work environment, and risks associated with the job or task.

Example, lone workers may be confronted by an angry customer or a violent person, work in an office or store location in a high crime area, work during the night shift when no assistance is available, or handle risky tasks such as depositing cash in a bank, opening or closing stores at odd hours or handling potentially dangerous machinery or chemicals.
