ERGONOMICS-What is it?

§  ERGONOMICS is  a way to work smarter--not harder by designing of tools, equipment, work stations and tasks to  fit the job to the worker--NOT the worker to the job:
        Layout
        Lighting & Temperature
        Process etc…
§  Derived from two Greek words: “Nomoi” meaning natural laws
                                            “Ergon” meaning work
§  Hence, ergonomists study human capabilities in relationship to work demands.

History:
      As early as 18th century doctors noted that workers who required to maintain body positions for long periods of time developed musculoskeletal problems.

Within last 20 years research has clearly established connections between certain job tasks.
Elements at work:
1)  Static work: musculoskeletal effort required to hold a certain position, even a comfortable one. Example: sit & work at computers.

2)  Force: amount of tension our muscles generate. Example: tilting your head forward or backward from a neutral, vertical position quadruples the amount of force acting on your lower neck vertebrae.
Facts:
      Work Related Musculoskeletal Disorders (WMSDs) are fastest-growing injury/illness category.
      Up 600% over last 11 years. Crores of total injury cost / year & case compensation claim cost. More lost workdays.
      The average person working at a keyboard can perform 50,000 to 200,000 keystrokes a day.
      Overexertion, falls  & RMI are the most common cause of workplace injury.
An average of 125,000 back injuries due to improper lifting each year.
How Reduce/ Eliminate?
      Good ergonomic design of your workstation DOES improve personnel comfort, health, morale and productivity.
      Individual awareness is one of the greatest means of identifying / improving workplace ergonomic issues.
      It’s critical to seek prompt medical aid for symptoms of ergonomic stress / Cumulative Trauma Disorders (CTDs).
CTD Risk control: 

Neutral & Comfortable:          
  •   Wrists straight
  • Shoulders relaxed with elbows close to body
  • head / shoulders & back in vertical alignment
  • Frequent breaks especially when bent postures can’t be avoided
