  2. 2. INTRODUCTION The cause of back pain in about 90% of cases is strain or sprain of back muscles ligaments or softstrain or sprain of back muscles, ligaments or soft tissue. These conditions generally heal completely, but often recur if prevention strategies are notbut often recur if prevention strategies are not used. B k i i h i i 10% f i dBack pain in the remaining 10% of cases is due to more serious conditions such as degenerative disk disease or herniated disks in the spinedisease or herniated disks in the spine. Each year 13 million people go to the doctor for chronic back pain Lifting-related injuries include: Sprains , Strains, Neural related, Neuro-muscular related injuries And/or bone related injuries doctor for chronic back pain Hand and Knife Safety | April 2010 | Drims#5505437 j j These injuries can affect any part of the body, but the majority occur to the lower back.
  3. 3. A HERNIATED DISK? • » Disks are soft, rubbery pads found between the hard bones (vertebrae) that make up the spinal column • » Disks allow the back to flex and bend (also act as shock absorbers) • » The center of the disk is a gel-like substance called the nucleus • » A disk herniates or ruptures when part of the center nucleus pushes the outer edge of the disk into the spinal canal and puts pressure on the nerves Of all factors responsible for herniated disks, aging is probably thep , g g p y most important • Disks have a high water content. As people age, the water content decreases, so the disks begins to shrink and become less flexiblebegins to shrink and become less flexible Other conditions that can weaken the disk include d t ( R t d h lifti )• wear-and-tear (ex. Repeated heavy lifting) • carrying excessive weight • bad posture (sitting and standing) i lifti• improper lifting • sudden pressure (ex. Auto accident or a fall)

  5. 5. What can we do to prevent Back injuries (1) Recognize the causes of back injuries – Hazard Identification: Assess the task:Assess the task: Posture Pacing, rate of work, breaks Requirements for team handling Assess Your Own Capabilities: Strength, height, etc. Health problems G d fitGender, age, fitness Assess the Load: Weight, shape, size Handles, packagingg , p , , p g g Stability Contents: hot, cold, hazardous Assess the environment: Space constraintsSpace constraints Flooring condition, levels Temperature, humidity, ventilation Tidiness, general housekeeping Slide 5 Hand and Knife Safety | April 2010 | Drims#5505437
  6. 6. What can we do to prevent Back injuries (2) Plan and prepare load Task Prepare the load: What is the most appropriate posture? Is there mechanical aid available? Is there anyone else to help? Route Prepare the load: Can the load be split? Can the load be made more stable? Make sure contents are evenly distributed? M th l d’ t f it l tRoute Consider start and end points Can any obstructions be cleared Move the load’s center of gravity close to yours Cover sharp / abrasive edges Prepare yourself and the area:p y Check space constraints Move obstacles Check final destination Check housekeepingCheck housekeeping Get a good grip on the load Use PPE where appropriate Hand and Knife Safety | April 2010 | Drims#5505437
  7. 7. What can we do to prevent back injuries(3) Apply principles of biomechanics to reduce the load on the spine • Keep a wide base of support. • Maintain the lumbar curve (low back) as much as possible. • Get a good grip. Position feet in direction of travel• Position feet in direction of travel. • Use smooth controlled movements. • Use friction to minimize force. • Try to avoid twisting and stoopingTry to avoid twisting and stooping. • Use team lifting where appropriate. Back Injury Prevention • Reducing exposure to known risk factors o Repetition, Awkward Position, Object weigh, Load Distribution. Object friction.

  8. 8. What can we do to prevent Back injuries (4) Back Injury Prevention • Avoid lifting and bending whenever you can. • Place objects up off the floor. • That way you won’t have to reach down to pick them up again. Raise / lower shelves• Raise / lower shelves. • The best zone for lifting is between your shoulders and your waist. • Put heavier objects on shelves at waist levelPut heavier objects on shelves at waist level, lighter objects on lower or higher shelves.

  9. 9. What can we do to prevent back injuries (5) Use the Hierarchy of Control to reduce the likelihood d it f b k i j iand severity of back injuries: • CHECK whether you need to move it at all • CONSIDER automation, particularly for new processes. • THINK about mechanization, like the use of a lift truck, • BEWARE of new hazards from automation or mechanization e.g:g 1. An automated plant still needs cleaning, maintenance etc 2. Lift trucks must be suited to the work and have properly2. Lift trucks must be suited to the work and have properly trained operators. • REMEMBER to assess the risks Slide 9 Hand and Knife Safety | April 2010 | Drims#5505437
