Aim of Ergonomics

• Optimum use of Human capabilities
  
• Improving Physical, Mental and Spiritual Health and well being.
  
• Individualization of work station.
  
• Economization of energy use by adjusting the Intensity and Extent of work load, recovery time and nutritional requirements.
  

General Ergonomic Principles

1. All work activities should permit the worker to adopt several different, but equally comfortable and safe postures.
   
2. Where muscular force has to be exerted it should be done by the largest appropriate muscle groups available.
   
3. Work activities should be performed without unease, discomfort and pain.
   
4. Work environment should be free of unhealthy exhausts, particles.

Use of Ergonomics

• Designing work stations that have the previously mentioned characteristics.
  
• Advising people about working postures
  
• Correcting the already damaged body through corrective exercises.
  
• Designing information in an easily understandable fashion.
  
• Designing work environment where light, sound levels and particulate matter is properly managed.
  
• Designing protective gear for violent environments.
