Ergonomics
ERGONOMICS :: TRAIN-THE-TRAINER PROGRAM
• “Ergonomics is an applied science concerned with the design of workplaces, tools, and tasks that match the physiological, anatomical, and psychological characteristics and capabilities of the worker.” Vern Putz-Anderson
• “The Goal of ergonomics is to ‘fit the job to the person,’ rather than making the person fit the job.” Ergotech
• “If it hurts when you are doing something, don’t do it.” Bill Black
What is Ergonomics?
ERGONOMICS :: TRAIN-THE-TRAINER PROGRAM
• Dates back to Ramazzini 1700’s
• Gained significance during WWII for airplane cockpit layout
• Progressed slowly until the 80’s and 90’s with the advent of the computer and more efficient workplace design
• Now, guidelines are in place and greater use of technology
