Ergonomics at workplace

  1. Ergonomics At Workplace 1.Navnath Adsul 2. Aditya Devadhe 3.Chaitanya Ghorpade 4.Vaibhav Sanap
  2. What is Ergonomics? ERGO=“work” NOMICS= “rules” or “laws”  Ergonomics literally means “the laws of work”
  3. SO EXACTLY WHAT IS ERGONOMICS? It is study of people efficiency at their working environment. It is one of the definition of Ergonomics. It is understandable that there are different definitions because ergonomics is all about differences
  4. DIFFERENCES  This are differences in size, shape, strength and ability of individual workers. This differences call for different designs in equipment , furniture, Workstations and routines.
  5. ERGONOMICS  Ergonomics is used in a workplace to help prevent repetitive and cumulative injuries.
  6. 3 Main Ergonomic Principles: 1. Work activities should permit worker to adopt several different healthy and safe postures. 2. Muscle forces should be done by the largest appropriate muscle groups available 3. Work activities s/b performed with joints at about mid-point of their ROM (esp. head,trunk, UE)
  7. FACTS The average person working at a keyboard can perform 50,000 to 200,000 keystrokes a day Overexertion & falls are the most common cause of workplace injury An average of 125,000 back injuries due to improper lifting each year. Muscles overuse results in tiny tears in the muscles and scarring; these contribute to inflammation and muscle stiffness
  8. Ergonomic Factors Two Categories of Ergonomic Factors 1. Environmental  Hearing  Vision General comfort and health 2. Physical
  9. Environmental Factors  Some examples of ergonomic environmental problems are:  Sick Building Syndrome  Excessive noise  Improper lighting  Temperature extremes
  10. Physical Stressors Physical stressors place pressure or stress on parts of the body:  Joints, muscles, nerves, tendons, bones Sometimes these injuries are referred to as “Cumulative Trauma Disorders” (CTDs) or “Repetitive Strain Injuries” (RSIs)
  11. Types of Injuries • Muscle pain • Joint pain • Swelling • Numbness • Restricted motion • Repetitive stress injury • Repetitive motion injury • Cumulative trauma disorder • Musculoskeletal disorder
  13. Target Regions • Back • Upper extremities • Lower extremities
  14. Types of Problems or Mismatches  Physical Size  Endurance  Strength  Manipulative  Environmental  Cognitive
  15. Physical Size  Clearance  Reach  Equipment Size  Personal Protective Equipment (PPE)
  16. Cognitive  Machine Pacing  Shift Work  Morale  Psychosocial
  17. Musculoskeletal Disorders: Signs and Symptoms Decreased grip and/or pinch strength Swelling Fatigue Loss of function Numbness Burning sensation Tingling Pain Cramping Stiffness
  18. An ounce of Prevention is worth a pound of cure !
  19. What to do ?? a) Warm up & stretch before activities that are repetitive, static or prolonged b) Take frequent breaks from ANY sustained posture every 20-30 minutes c) Respect pain positions or stop painful activity d) Recognize early signs of inflammatory process
  20. Posture check Increased stress, decreased circulation…
  21. Posture Think of posture in terms of joint position Static and awkward postures lead to:  Decreased movement  Decreased circulation  Increased stress and fatigue
  22. Maintain Neutral Posture a) Maintain erect position of back & neck without shoulders relaxed b) Position equipment & work directly in front of and close to your major tasks c) Avoid static positions for prolonged time; muscles fatigue---MOVE to circulation!
  23. Modify Tasks a) Alternate activities frequently; rotate heavy &/or repetitive tasks without lighter less repetitive ones. b) If stress become worse REASSESS task setup & look for alternative methods c) Avoid repetitive or prolonged grip activities
  24. Correct & Incorrect Techniques
