Lecture on Musculoskeletal Disorders (MSDs) in Warehouse Settings

Introduction

• Sprains and Strains: Account for nearly 40% of injuries registered with Workplace Safety and Insurance Board.
• Focus: Importance of identifying potential hazards associated with MSDs in warehouses.
• Solution: Simple, low-cost measures can offset impacts on employees and organizations.

What are MSDs?

• Definition: Injuries and disorders of the musculoskeletal system (muscles, tendons, nerves, soft tissues).
• Common Areas Affected: Back (most common), shoulders, neck, elbows, hands, wrists.

Causes of MSDs in the Workplace

• Work Demands vs. Capabilities: MSDs occur when job demands exceed worker capabilities.
• **Main Hazards Associated with MSDs: **
  • Force: Moving product and equipment
  • Repetition: Repeated use of the same body parts with few breaks
  • Awkward Posture: Muscle tissue at a mechanical disadvantage

Specific Hazards in Warehouses

• Common Scenarios:
  • Substandard conditions
  • Poor lifting techniques
  • Habits threatening soft tissues over time
• Examples:
  • Repetitive bending, reaching, and twisting
  • Lifting above shoulder level or while holding load away from body
  • Long standing with weight on one leg
  • Heavy lifting after prolonged sitting
  • Twisting trunk instead of shifting hips to see behind
  • Awkward back/neck postures operating equipment
  • Exerting extra force to push/steer carts
  • Reduced dexterity in cold storage

Preventative Measures

• Training and Awareness:
  • Training on MSD hazards and safe lifting techniques
  • Increase awareness of good body mechanics and proper techniques
• Employee Involvement:
  • Involving employees in identifying and controlling MSD hazards
• Adjustments and Equipment:
  • Raising heavier items off the floor
  • Using adjustable lift tables
  • Ensuring appropriate and well-maintained equipment
  • Discussing box size/weight options with suppliers
  • Providing pull sticks for extended reaching
  • Promoting two-person lifts for heavy/awkward items
• Culture of Support: Rewarding supportive behavior

Impact of MSDs

• Operational Impact: Scheduling issues and reintegration challenges
• Reoccurrence Risk: Higher likelihood of reoccurrence once an MSD occurs
• Employee Impact: Debilitating for the affected employee

Conclusion

• Key Message: Prevention is key.
• Professional Help: Consider an ergonomic assessment by qualified ergonomists.
• Goal: Ensure staff are working smarter, not harder.
