Where a worker’s regular job tasks have the potential to cause a serious foot injury, safety shoes are essential. Foot injuries can happen in places where there are rolling or falling objects, things that can pierce the sole, or when there are electrical risks that are still present even after the employer has taken all other necessary precautions, like a static-discharge or electric-shock hazard. Unless there is a significant danger of foot injury, these recommendations are not intended to apply to tasks carried out by an employee on a unique or special occasion.
