'Ergonomics is designing to suit people. If the designer fails to take account of ergonomics the resulting product or system will be unsuitable for human operation or use and is likely to lead to a greater risk of human error and injury. In complex systems the resulting human errors can lead to catastrophic loss of life as in recent railway accidents and aircraft ones over a long period. In more mundane jobs the failure can lead to a lifetime of upper limb disorders or back pain.' Reg Sell, Past President and External Relations Officer, The Ergonomics Society, 2002 Ergonomics is the study human body in its working environment Ergonomics
