- 2. 2 Lifting process BEFORE YOU LIFT • Plan Your Route: Path clear? Trip hazards removed? Dry? • Assess the Load: Too heavy? Can I use a hand truck or forklift? Can I slide it? WHEN YOU LIFT • Lift It Right: Position your body close to the object. Keep your back straight. • Move It Right: Don't twist your back. • Lower It Right: When you put the load down, bend your knees not your waist. GET HELP IF YOU NEED IT • Work Together: Don't be a hero. Communicate with your partner!
- 3. 3 Plan ahead • Size up the load: ▪ Can it be split into multiple loads? ▪ Smaller loads cause less strain on the back. ▪ Can you slide it rather then lift? • Use material handling equipment if load is too heavy: ▪ Forklifts ▪ Hoists ▪ Dollies 9b
- 4. 4 Plan ahead • Avoid using lower rack for moderately heavy to heavy items or awkward items. • Get help when lifting heavy, awkward, or long items. 9a
- 5. 5 Basic rules of good lifting • Size up the load before you lift. • Can you lift a corner? • Can you get to the item? • Do you need to move something to gain better access? 1a
- 6. 6 Basic rules of good lifting • Bend your knees. • Get a good hand hold. • Center yourself over the load. • Lift straight up - let your legs do the work. • Don’t twist or turn. 1b
- 7. 7 Basic rules of good lifting • Have a clear path. • Set the load down properly. • Always push a cart or dolly. • Get help for long loads. • Split up heavy loads when you can. • Pushing a load is easier on the back; easier to control. 1c
- 8. 8 Never twist or turn when lifting • Adds strain to the back’s discs, muscles, ligaments, tendons. • Plan your lift to avoid awkward positions. • Set load down if you’re losing your grip. • Don’t twist and turn or juggle load to regain grip. • Keep back as straight as possible. 5a
- 9. 9 Carrying the load • Ensure a clear path. • Ensure a place where load can be set down. • Check for stability of load. • Can you get a good grip? 6a
- 10. 10 Carrying the load • Use mechanical equipment if load is too heavy. • Get help if load is too heavy - lift at the same time to keep load balanced. 6c
- 11. 11 Lowering the load • Bend the knees to let leg muscles support the weight. • Slowly lower it; do not drop the load. • Avoid sudden movements. • Lower the load at the same time if working with a partner. 7a
- 12. 12 Awkward Lifting Lifts that are: • Above the shoulders • Below the knees • At arms’ length
- 13. 13 Analysis tools • The closer to the body the more Strength you have. • L&I Lifting Calculator • Other tools: ▪ American Conference Group of Industrial Hygiene (ACGIH) Lifting Threshold Limit Value (TLV) ▪ National Institute of Occupational Safety & Health (NIOSH) Lifting Equation
- 14. 14 Principles for reducing heavy lifting • Reduce the weight • Increase the weight (to balance load) • Use mechanical assistance • Slide instead of lift • Team lifting
- 15. 15 Reducing heavy lifting Reduce the weight of the load Wood pallet 60 pounds Plastic pallet 20 pounds
- 16. 16 Reducing heavy lifting Use mechanical assistance Pneumatic conveyor
- 17. 17 Reducing heavy lifting Slide instead of lifting
- 18. 18 Principles for reducing frequent lifting • Use mechanical assistance • Avoid unnecessary lifting • Use mobile storage shelves
- 19. 19 Reducing frequent lifting Use mechanical assistance… … instead of lifting by hand
- 20. 20 Reducing frequent lifting Use mobile storage: Parts stay on racks as they move from one manufacturing process to the next.
- 21. 21 Principles for reducing awkward lifting/ Reaching • Remove obstacles • Slide closer • Reduce shelf depth • Reduce package size • Use mechanical assistance • Team lifting
- 22. 22 Reducing awkward lifting/ Reaching Slide objects closer “Homemade” hook for pulling small boxes to edge of shelf.
- 23. 23 Reducing awkward lifting/ Reaching Reduce package size
- 24. 24 Principles for reducing awkward lifting/ Bending • Use mechanical assistance to raise the load • Add handles • Arrange storage • Avoid unnecessary lifting
- 25. 25 Reducing awkward lifting/ Bending Use mechanical assistance to raise the load Scissor-lift cart
- 26. 26 Reducing awkward lifting/ Bending Add handles
- 27. 27 Reducing awkward lifting/ Bending Rearrange storage Heavy items at waist level
- 28. 28 Reducing awkward lifting/ Bending Avoid unnecessary lifting Tire hanger keeps wheels up off the floor in auto shop
- 29. 29 Principles for reducing awkward lifting/ Reaching above shoulders • Arrange storage • Use mechanical assistance • Use a rolling stair or “safety ladder”
- 30. 30 Reducing awkward lifting/ Avoid reaching above shoulders Arrange storage
- 31. 31 Reducing awkward lifting/ Twisting Use conveyors Allows boxes to be unloaded and checked in with minimal lifting
- 32. 32 Lifting techniques training Teach lifting techniques to employees: • Training alone is not effective. • Making changes to jobs and equipment is better. • Making changes along with training is most effective.
- 33. 33 Lifting techniques training • Job-specific, on-site, hands-on training is more effective than classroom. • Have employees demonstrate proper lifting techniques before “graduating.”
- 34. 34 Other factors in back injuries • Age of employee • Improper postures when sleeping, standing, sitting • Physical condition of employee • Repetitive motions 10a
- 35. 35 Conclusion • When lifting a box, think out of the box! • Is there a better way? • Don’t wait for someone to get injured before changing a job. • Just because we have done it this way. Do we have to continue to use the same method to handle a loading and unloading of materials?
