Human Factors Engineering - Ergonomic - sewing

  1. 1. Jordan university of science and Technology Human factors classic fashion industryclassic fashion industry Eng: Heba Al Daas Eng: Dania Ta’ani
  2. 2. introduction --Our case study was about Ergonomics in classic fashion apparelOur case study was about Ergonomics in classic fashion apparel industry Ltd Coindustry Ltd Co.. -Workers involved in sewing activities, such as manufacturing garments and shoes may be at risk of developing musculoskeletal disorders (MSDs). Sewing-related injuries have been documented in the areas of sewing stations, performing fine work or scissor work, and material handling, among others.
  3. 3. -Sits for long hours on uncomfortable chair with no back support. -bend her neck and back. -Pulls fabric with left hand as she sews. -Press pedal for sewing machine all .day with bare feet -Pressure on the back of leg. Solution: Provide adjustable treadle so the worker can place it in a comfortable position and get as close to the table as possible Use job/task rotation through tasks that do not require constant leg pressure and awkward leg posture.
  4. 4. Wrong work place design: Not enough space for moving it may injure the spine the table doesn’t allow enough room underneath for the worker's to move and Uncomfortable chair Solutions: Provide worker with Adjustable table, adjustable chair
  5. 5. Fine work -Acute visual requirements, coupled with intense wrist, hand, finger movements excessive bending for back and neck -Bad ventilation -Insufficient lighting may cause eye fatigue and headache. Solution: Use adjustable task lighting to make it easier for the worker to see product during set up
  6. 6. Not sufficient work place design The machine stands on workers hollow that prevent them from moving easily Solution :We should redesign the work place and put the machine in more suitable place
  7. 7. Over exertion repetitive motion & raising hands over shoulder may cause impingement syndrome
  8. 8. solution: To prevent ergonomic injures workers should be encouraged to rotate tasks or take frequent, short breaks to stretch and relax muscles. Repetitive motion for very long hours & bending wrist may cause carpal tunnel syndrome.
  9. 9. Bad design poor hand grip may cause: Cuts ,strain, blisters stress on fingers Solutions: -Using good grips tools. -Avoid using more force than the job requires ,use partially automated tools to reduce force and repetition of pinch grip. -Use job rotation through tasks that do not require pinch grips.
  10. 10. Quality check point: Require workers to stand for very long period of time that may injure the spine Blood circulation is not effective in standing due to gravity. Solutions: Provide sit/stand workstations, which encourage changing posture & provide external support or frequent movement.
  11. 11. :packaging -Over exertion on arm and shoulders it may cause fatigue. -Bending the spinal. -Repetitive motion. -Standing for long hours. -No space for moving his feet. Solution : -Provide table next to him so he wont stretch his arm -They Should redesign the work place to provide the worker external support or frequent movement.
  12. 12. Packaging: Workers repeatedly bend at the waist and reach into transportation containers to load fabric, causing stress on the back and arms injury. solutions: Use height-adjustable carts to reduce the need to bend or reach into the carts or provide her with good chair.
  13. 13. Handling materials: -awkward postures, Repeated torso twisting while lifting which may result in back and shoulder injuries. -Lifting objects with arms fully extended or lifting from floor level or above shoulder level. Solutions: -Design stations to allow most lifts at waist level -Use mechanical lifts, ceiling tracks or carts to transport the fabric to reduce the risk of injury to the workers.
  14. 14. -Ladder not safe with no breaks so the worker may fall down. -The ladder is not tall enough so the worker will exert his arm to putt the heavy Rolls on the high shelves. -over exertion on arm & stress on shoulders joints.
  15. 15. -The worker is climbing on the shelves to load the stock garments its dangerous & he may falls and may break some bones. Solutions: provide the workers with a suitable ladder.
  16. 16. Bad ventilation & hot place they should isolate the ironing section because it affect the other sector bending and stress on shoulder
  17. 17. 1-Because a garment factory uses many heated processes, it is important for workers to avoid heat stress by drinking plenty of water during their shift 2-Water coolers are very far from work space just one source for water not so clean not provided with cups Solution: Proper ventilation can help to reduce ambient temperatures and ensure worker comfort Drinking water by providing them with several water coolers
  18. 18. lightening -poor lighting at work can lead to: eye strain, fatigue headaches, stress and accidents
  19. 19. On the other hand, too much light can also cause health and safety problems such as “glare” headaches and stress. Both can lead to mistakes at work, poor quality and low productivity Solution: Good lighting and avoid in terms of improved productivity, and a reduction in .errors
  20. 20. Noise : Too much worker with so many machines.
  21. 21. Unsafe floor
  22. 22. There is a role in the factory that force worker to clean the work place around them and its an attempt to maintain workplace clean. Baring feet Lake of cleaning tools Bending & flexion harmful dust. solution: must provide enough cleaning tools provide face masks
  23. 23. Un healthy work environment that may pollute the place and affect the worker negatively.
  24. 24. -Uncomfortable environment for work -Uncovered cables -Storing stuff in wrong place may disable the workers movement and may cause injuries
  25. 25. Worker awareness
  26. 26. Worker awareness good drawing surface
  27. 27. Safety Precautions
