Thousands of debilitating injuries and wrongful deaths occur every year due to occupational hazards. Workplace hazards are often grouped into physical, chemical and psychosocial hazards. Physical hazards can include slips and falls, dangerous machinery, and electricity (shock), chemical hazards can include agents such as solvents, plastics, toxic properties found in asbestos, benzene and vinyl chloride, and psychosocial hazards can include work-related stress, sexual harassment, and any kind of verbal or emotional abuse.
