3 Objectives At the end of this session you will be able to: Basic understanding of your backUnderstand principles of safe manual handlingKnow when to stop!
4 are affected with back pain Did You Know ?80%of peoplein the western worldare affected with back pain
5 Manual Handling - Definition Any transporting or supporting of a load by one ormore employees and which may include;LIFTINGPUTTING DOWNPUSHINGPULLINGCARRYING OR MOVING A LOADwhich by reason of it’s characteristics or unfavorableergonomic conditions involves risk, particularly of back injury to employees
6 1. LEGISLATION Safety, Health and Welfare at Work Act 1989 (General Application 1993) Regs.
7 2. Anatomy Why Is It important? The Musculo-skeletal System of the body is designed for movementIn order to lift and handle an object safely it is essential to have a knowledge of this system and its flexibility
10 Facet JointsOnly in Lumbar SpineGliding movement
11 Spinal cordDown through the centre of the spine we have our spinal cordThis brings messages to the brain from the rest of the body and from the brain to the rest of the bodyNerves from the spinal cord control the movement of the trunk, arms and legsAnd convey all sensationsIf you break the spinal cord you will be paralysed !
12 Muscles The spine is strengthened and made moveable by muscles. This makes your back flexible as opposed to a fixed bamboo like situationPosture muscles are not designed for lifting
13 Spinal LigamentsLigaments: soft tissue in joint capsule. Limit mobility.Long LigamentsLimit movement of spineLigaments have certain degree of elasticity. If the stretching limit is reached injury will occur.
14 Types of Back PainThere are over 100 accepted causes of low – back pain (small of the back)Wear and tear being the most commonThree types of mechanical back injury which may be caused by poor manual handling practiceDISC INJURYSOFT TISSUE INJURYBONY INJURY
15 Disc Degeneration - Gradual Nutrition cannot get to discDisc dries outLack of nutrition leads to disc degenerationEXPERIENCE A HIGH LEVEL OF PAIN DUE TO PRESSURE ON NERVE ENDINGS
16 Disc PressureWhen pressure is applied on the spinal nerves pain can be felt in several areasSciatica is caused by disc pressure on the sciatic nervePain Distribution
17 Wear and TearWear and tear effects can be noticed from as early as 25 years of age – earlier if there has been an injuryHeavy physical work over a long period causes wear & tearRemember we should only lift what we are physicaly able to lift at the time of the liftMuscles are strained by over loading or a sudden stretch or unexpected movementThe more we overdo- the less we can do
18 Ergonomic AssessmentInformation required to carry out an ergonomic assessment:THE TASKSTHE LOADSTHE WORKING ENVIRONMENTINDIVIDUAL CAPABILITY
19 5. Principles of Lifting Assess Task, Area, Load Broad Stable Base (Feet Flat on Floor)Bend the KneesBack Straight (Not necessarily vertical)Firm Grip (Palmer)Arms in Line with TrunkWeight Close to Centre of GravityPoint feet in the Direction of Movement
20 Principles of Lifting Divide the load Balance the body Example - Two smaller loads - as opposed to one large one
21 Pushing and Pulling Keep your back straight Bend at the hips and knees Let your legs do the workPushing is better than pullingPushing is easier as you can see over the loadIf you can’t see over the load GET HELP
22 6. Practical application To and from the floorTo and from a benchTo and from a heightPushingPulling2 persons lift
23 Summary There is legislation to help and protect you Being aware of your body and how it works will prepare youBeing flexible and fit will benefit youHandling loads correctly is the only way
24 ……nobody is immune to natural wear and tear Health & Safety OfficeThank you for your time&Remember…….……nobody is immune to natural wear and tear……use it or lose it!
