1. Seminar Topic Name : WORK ERGONOMICS Name : Mrs. Aneri Desai Roll No. : 19304922009 Course Name : PDIS Center Name : RIL Hazira Subject Name :Project (With Seminar)

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 differences call for different designs in equipment , furniture , Workstations and routines. This are differences in size, shape, strength and ability of individual workers.

5. ERGONOMICS Ergonomics is used in a workplace to help prevent repetitive and cumulative injuries.

6. 3 Main Ergonomic Principles: Work activities should permit worker to adopt several different healthy and safe postures. Muscle forces should be done by the largest appropriate muscle groups available 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 Rep etitive motion injury Cumulative trauma disorder Musculoskeletal disorder

12. ERGONOMIC STRESS AREAS Knee Hip

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 ?? Warm up & stretch before activities that are repetitive, static or prolonged Take frequent breaks from ANY sustained posture every 20-30 minutes Respect pain positions or stop painful activity 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 Maintain erect position of back & neck without shoulders relaxed Position equipment & work directly in front of and close to your major tasks Avoid static positions for prolonged time; muscles fatigue- --MOVE to circulation!

23. Modify Tasks Alternate activities frequently; rotate heavy &/or repetitive tasks without lighter less repetitive ones. If stress become worse REASSESS task setup & look for alternative methods Avoid repetitive or prolonged grip activities
