Visual Demands of the Work Geometry of the Work Station Inadequate Seating Analysis Reveals That 40% of Operators at Sewing Machines Stoop Forward > 20 o Throughout the Machine Cycle 60% Tilt Their Heads Forward > 20 o Throughout the Machine Cycle - Why? Visual Demands of the Work Geometry of the Work Station Inadequate Seating

9. Postural Stress and Lighting Precise Stitching Tasks are Visually Demanding Thread and Fabric Often Offer Little or No Visual Contrast 36% of Operators Feel Lighting is Inadequate Surveys Found Light Levels at Less Than 60% of Recommended Levels Operators Lean Forward to See Their Work Precise Stitching Tasks are Visually Demanding Thread and Fabric Often Offer Little or No Visual Contrast 36% of Operators Feel Lighting is Inadequate Surveys Found Light Levels at Less Than 60% of Recommended Levels Operators Lean Forward to See Their Work

10. Seating Straight Backed Wooden or Metal Chairs are Typical in the Industry Chairs Often Lack Cushioning Chairs Often Lack Adjustable Back Rests Chairs Often Lack Height Adjustability Improved Seating is Readily Available Straight Backed Wooden or Metal Chairs are Typical in the Industry Chairs Often Lack Cushioning Chairs Often Lack Adjustable Back Rests Chairs Often Lack Height Adjustability Improved Seating is Readily Available

11. PsychoSocial Considerations Psychomotor Demands are High (Speed, Accuracy, Coordination) Positive Attitudes Toward Work are Inversely Related to Increased Monotony and Fatigue Positive Attitudes Toward Work are Directly Related to Job Satisfaction Psychomotor Demands are High (Speed, Accuracy, Coordination) Positive Attitudes Toward Work are Inversely Related to Increased Monotony and Fatigue Positive Attitudes Toward Work are Directly Related to Job Satisfaction

12. Work Organization As Many as 100% of Piecework Operators in High Manipulation Jobs Have Symptoms of CTDs Workers in Piecework are 4 Times as Likely to Develop Severe Disabilities as Hourly Workers Workers in Piecework are 9 Times as Likely to Develop Arthritic and Osteoarticular Disorders as Hourly Workers As Duration of Employment in Piecework Increases, So Does Severe Disabilities As Many as 100% of Piecework Operators in High Manipulation Jobs Have Symptoms of CTDs Workers in Piecework are 4 Times as Likely to Develop Severe Disabilities as Hourly Workers Workers in Piecework are 9 Times as Likely to Develop Arthritic and Osteoarticular Disorders as Hourly Workers As Duration of Employment in Piecework Increases, So Does Severe Disabilities

13. Duration of Exposure Machine Operators Experience Cumulative Damage to the Neck and Shoulders Over Time Risk for Persistent Neck and Shoulder Pain Increases With Years of Employment as a Machine Operator Work for More Than Eight Years as Machine Operator Increases Risks For Neck and Shoulder Pain Machine Operators Experience Cumulative Damage to the Neck and Shoulders Over Time Risk for Persistent Neck and Shoulder Pain Increases With Years of Employment as a Machine Operator Work for More Than Eight Years as Machine Operator Increases Risks For Neck and Shoulder Pain

Work Enhancements Foam Padded Edges to Sharp Table Edges Provide Cloth Upholstered Adjustable Chairs Angle Packing Boxes to Workers With Tilt Equipment Provide Anti-Fatigue Matting for Standing Workers Improved Lighting Require Rest Periods Job Rotations Foam Padded Edges to Sharp Table Edges Provide Cloth Upholstered Adjustable Chairs Angle Packing Boxes to Workers With Tilt Equipment Provide Anti-Fatigue Matting for Standing Workers Improved Lighting Require Rest Periods Job Rotations

17. Automated Materials Handling Eliminates Heavy Lifting by Operators or Bundle Boys Uses Pre-Programmed Hanging Conveyor Moves Only One or a Few Work Pieces Per Hanger Computer Controlled - Movement Tracked by Bar-Coded Hangers and Series of Scanners Delivers Work to Queue Near Operator Eliminates Heavy Lifting by Operators or Bundle Boys Uses Pre-Programmed Hanging Conveyor Moves Only One or a Few Work Pieces Per Hanger Computer Controlled - Movement Tracked by Bar-Coded Hangers and Series of Scanners Delivers Work to Queue Near Operator

18. Automated Materials Handling Strong on Pre-Programmed Use But Weak on Flexibility (Short Term Changes, etc.) Technology is Rapidly Improving Future Models Will Direct More Work to the Queues of the Most Productive Workers and Less to Slower Workers or Beginners Strong on Pre-Programmed Use But Weak on Flexibility (Short Term Changes, etc.) Technology is Rapidly Improving Future Models Will Direct More Work to the Queues of the Most Productive Workers and Less to Slower Workers or Beginners

19. Modular Manufacturing Concept Conventional Textile/Apparel Industries Use the Progressive Bundle System - Each Operator is Assigned to a Single Operation In Modular Mfg. a Complete Garment is Produced in a Modular Cell Cells May Have 10 Operators and 20 Machines Operators Are Not Assigned to a Single Operation But Move Between Workstations Conventional Textile/Apparel Industries Use the Progressive Bundle System - Each Operator is Assigned to a Single Operation In Modular Mfg. a Complete Garment is Produced in a Modular Cell Cells May Have 10 Operators and 20 Machines Operators Are Not Assigned to a Single Operation But Move Between Workstations

20. Modular Manufacturing Concept Teams of Operators are Responsible for Work Planning and Management, Product Quality, etc. Employees are Empowered - Boosts Morale A Variety of Motions are Used by Each Operator - Reduces Risk for CTDs and Relieves Static Postures Can Be Reconfigured Rapidly, Providing Great Flexibility Teams of Operators are Responsible for Work Planning and Management, Product Quality, etc. Employees are Empowered - Boosts Morale A Variety of Motions are Used by Each Operator - Reduces Risk for CTDs and Relieves Static Postures Can Be Reconfigured Rapidly, Providing Great Flexibility

21. Modular Manufacturing Significantly Reduced Absenteeism Necessitates Better Ergonomic Designs of Workstations to Accommodate Different Operators Many Operations Converted to Standing Workstations Instead of Seated Workstations Employees Paid on a Group Incentive System Significantly Reduced Absenteeism Necessitates Better Ergonomic Designs of Workstations to Accommodate Different Operators Many Operations Converted to Standing Workstations Instead of Seated Workstations Employees Paid on a Group Incentive System
