Lighting plays an essential role in proactive defence against accidents and injuries in the workplace. When lighting conditions are optimal, it can increase productivity while improving the quality of work. Optimal lighting provides workers with an environment where they can clearly read labels and instructions; allowing workers to identify tripping hazards and perform tasks at hand safely.  

  Workplace-lighting needs can be identified with workers, both at safety meetings and before tasks begin. Correcting lighting issues does not always mean adding more light fixtures. Here are some ways to correct insufficient lighting:
- Replace bulbs on a regular schedule. Old bulbs give less light than new ones, so replace them before they burn out. Follow manufacturers’ instructions.
- Clean light fixtures regularly. Dirty light fixtures give off less light.
- Use more reflected light and local lighting to eliminate shadows. For example, a covered light mounted under a transparent guard on a grinding wheel provides the added light needed to see clearly.
