Details of Incident / Close Call: 

Worker was loading 40kg bags of salt from a pallet into the back of his pickup truck, one bag at a time. The worker followed the procedure of bending his knees, picking up the bag, turning and placing it into the back of the truck.

While picking up the 12th bag of salt, the worker experienced a sharp severe pain in his lower back during the turning motion. The pain extended from his lower back down through his left leg.
The worker immediately released the bag, ceased activity, and reported the incident to his supervisor.


Learnings and Suggestions: 

  • Restrict manual lifting to a maximum of 50 pounds (22.7 kg)
  • Review proper lifting, lowering, pulling, pushing , and / or carrying techniques with workers:
    • Place feet apart for good balance
    • Bend at your knees, not at your waist. This will help you keep your center of balance and let the strong muscles in your legs do the lifting
    • Use gradual motions (smooth and slow)
    • Avoid awkward work positions such as bending, reaching, and / or twisting
    • Try to keep the load between your knees and shoulders without twisting your body Pivot with your feet instead of twisting your back
    • Keep loads close to your body
    • Avoid reaching objects that are above your shoulder height (keep objects and loads between your shoulders and mid-thigh level)
    • Get a good grip. Use your hands and not just your fingers to grip load
  • Utilize a forklift to lift the bags so they can be slid into place
  • Utilize at least 2 people to lift weights in excess of 50 pounds (22.7 kg)
  • Where feasible purchase product in bags that do not exceed 50 pounds (22.7 kg) or break product down into smaller quantities
