Manual Handling Presentation........................
- 1. Manual Handling Ian Stone Health and Safety Advisor
- 2. Aims and Objectives Provide sufficient understanding and knowledge of Manual Handling, the risks involved and the control measures available.
- 3. How? • Theory • Discussion • Practical Demonstrations
- 4. What Is Manual Handling? • Any transporting or supporting of a load by hand or bodily force • This includes: • Lifting, putting down, pushing, pulling, carrying or moving • This human effort can be applied indirectly
- 5. What Is Manual Handling? • Such as hauling on a rope • Pulling a lever • Applying a force to manipulate a load supported on a • Spade • Fork • or similar implement
- 6. Manual Handling Facts •Low back pain occurs with the same frequency in people with sedentary occupations as those in heavy labour •Musculo-skeletal disorders arising from work situations have an estimated annual cost in the region of £3 billion and account for 30 million lost work days each year •Smokers are more likely to suffer back pain than non-smokers
- 7. Manual Handling Facts • Being overweight increases the likelihood of back pain • Age doesn’t necessarily make any difference, bad backs affect people of all ages • Poor handling techniques when you are young will contribute to problems in later life • Those who have suffered from a back injury are three times more likely to suffer injury again
- 8. Reasons for Manual Handling Training •Reduce lost working days through injury •The Law •Looking after one of the most important parts of the body
- 9. Kinds of Accident Causing Injury 1996/97 From HSE Handling 36.5% Struck by 20.4% Trips 19.1% Falls 6.9% Other 12.6% Machinery 4.5% Handling Struck by Trips Falls Other Machinery

- 11. Sites of injuries caused by handling 1996/97 From HSE Back 49.3% Rest of Torso 6.6% Arm 10.3% Hand/Wrist 8.5% Finger/Thumb 14.3% Low er Limb 7.7% Other 3.3% Back Rest of Torso Arm Hand/Wrist Finger/Thumb Low er Limb Other
- 12. The Law & Manual Handling •The Health and Safety at Work etc Act 1974 (HASAWA) •The Management of Health and Safety at Work Regulations 1999 (MHSWA) •The Manual Handling Operations Regulations 1992
- 13. The Law & Manual Handling HASAWA: General duty to ensure the health, safety and welfare at work of their employees. In particular, they have a duty to ensure the safe use, handling, storage and transport of articles and substances so far as is reasonably practicable.
- 14. The Law & Manual Handling MHSWR: Regulation 3(1) requires employers to risk assess work activities. This risk assessment should identify whether there is a risk of injury from manual handling operations in the workplace.
- 15. The Law & Manual Handling The Manual Handling Operations Regulations 1992: These regulations are based on an ergonomic approach to preventing manual handling injuries. This involves fitting the job to the worker, taking into account anatomy, physiology and psychology.
- 16. The Law & Manual Handling Whereas previous legislation set limits on the weight of loads that can be lifted, these regulations require a number of relevant factors to be taken into consideration:
- 17. The Law & Manual Handling These are known as TILE: Task Individual Capability Load Environment
- 18. Relevant Factors Task: What is it about the way that we organise the task which might affect our health and safety? Individual Capabilities: What is it about the people who are doing the job that might affect their health and safety? Load: What is it about the load which might affect our health and safety? Environment: What is it about the place which might affect our health and safety?
- 19. The Law & Manual Handling These regulations set out a hierarchy of measures employers should work through to prevent or reduce the likelihood of injury: • Avoid manual handling • Assess the task • Reduce the risk • Monitor the task • Inform and train staff on residual risks
- 20. Avoid Manual Handling Eliminate: • By design- Reduce heavy structural materials, layout of workplace to minimise manual handling operations • Automation/mechanisation:- Cranes, hoists, forklift trucks, sack trolleys etc • Management- Delivery of heavy articles to point of use, storing heaviest materials at waist level
- 21. Main Types of Injury •Traumatic:Strain/Sprain, Slipped Disc •Repetitive:Effects overtime, Arthritis
- 22. Cumulative Manual Handling Injuries •Back Pain •Neck •Shoulders •Knees •Feet •Wrist/Elbows •Hernia •Overall Fatigue •Many Others
- 23. Work Related Upper Limb Disorders (WRULD) Affects shoulders, arms and wrists Main Causes: • Excessive force • Excessive repetition • Lack of recovery time or rest • Poor static posture • Stress • Individual susceptibility
- 24. Causes of Back Pain Not just caused by heavy work and heavy weights Can be due to: •Poor static posture •Sitting too long in one position •Sudden movement •Vibration during handling •Psychological stress
- 25. INJURIES CAUSED BY MANUAL HANDLING ARE RARELY FATAL, BUT…. Can cause permanent disability
- 26. The Spine Spine - 3 main functions. To protect the spinal cord To allow movement. To support the upper body.
- 27. The Structure & Function of the Spine •Provides a flexible connection between the upper and lower half of the body •Encloses and protects the spinal cord •Is involved in most movements of the trunk and limbs by providing key attachment points for muscles •Has a very significant function in weight bearing but only with correct posture •Is very prone to injury if used incorrectly
- 28. The Human Spine(backbone, spinal column) Consists of a column of small bones each called a VERTEBRA • If numbered 1-33 (starting with 1 nearest the skull): • 1-7 are known as “CERVICAL VERTABRAE” • 8-19 are known as “THORACIC VERTABRAE”
- 29. The Human Spine(backbone, spinal column) • 20-24 are known as “LUMBAR VERTABRAE” • 25-30 Fused Vertebrae known as “SACRUM” • 30-33 Fused Vertebrae known as “COCCYX”
- 30. The Human Spine(backbone, spinal column)
- 31. The Spine Each muscle in the back can move 1.25 cm • Multiply this movement by 33 vertebrae and this allows us to bend •The body is 20mm shorter at the end of the day than at the start
- 32. The Spine • Each vertebrae is separated by a gel like substance, the disc. These discs bend and stretch as we move
- 33. The Spinal Cord The Spine protects the spinal cord. The spinal cord and the nervous system controls all systems in the body. As the cord descends from the brain nerves peel away from the cord at each vertebrae, leading to all other parts of the body. Damage to the cord will result in the blockage of signals from the brain to the area affected.
- 34. The Spinal Cord
- 35. The Nerves
- 36. Slipped Disc • A slipped disc is also called a “herniated or prolapsed” disc • It is a bulge in the wall of one of the discs between the vertebrae pressing onto the nerve
- 37. Slipped Disc • Main symptom is sciatica (pain in legs, back and buttocks) • Other damage often occurs at the same time, such as muscles strain and tears Treatment: • Minimum stress to the spine • Correct posture • Time to heal
- 38. Forces 1kg Weight close to the body exerts 10kg force onto muscles of the back (1:10) 1kg Weight held at arms length exerts 100kg force onto the muscles of the back (1:100)
- 39. How to Lift
- 40. 1.Stop and Think
- 41. 2.Place the feet
- 42. 3.Get a Firm Grip
- 43. 4.Don’t Jerk
- 44. 5.Move the Feet, Keep Close to the Load
- 45. 6.Put down, Then adjust
- 46. Lifting and Lowering Limits Guidance for tasks performed less than 30 per hour
- 47. Lifting and Lowering Reductions • Stooping: • 25% for 20° • 35% for 45 ° • 50% for 90 °
- 48. Lifting and Lowering Reductions • Twisting: • 10% for 30° • 15% for 60 ° • 20% for 90 °
- 49. Lifting and Lowering Reductions • Guidelines for tasks more than 30 per hour: • Reduce 30% for once/twice per man • 50% for five-eight per man • 80% for 12 per man
- 50. Lifting and Lowering Reductions • Carrying: Max 10m without a rest • Pushing/Pulling: Max starting/stooping force 250 Newton's (25kg) 16kg for women • Max force for keeping load in motion 100 Newton's (10kg) 7kg for women • Seated: Max figure (close to body & between work surface and shoulder height) 5kg, 3kg for women
- 53. Manual Handling Principles • Stay balanced • Keeping your centre of gravity close to the load’s centre of gravity • Bending from the knees • Keeping the back straight, and head up • Staying compact when pushing • Moving the feet to turn, not the body • Moving smoothly, particularly when setting loads down
- 54. Important • Knowledge and training alone will not guarantee safe handling • A risk assessment needs to be undertaken • Avoid if possible • Know your own limits • Put training into action at work as well as home
- 57. And Finally
- 58. Hurt at Work • You've carefully thought out all the angles. • You've done it a thousand times. • It comes naturally to you. • You know what you're doing, its what you've been trained to do your whole life. • Nothing could possibly go wrong, right ?
