Manual Handling Training
SAFELAB COURSE
2
Introduction
  • Legislation
  • Anatomy
  • Ergonomics
  • Principles of lifting

3
Objectives
  • At the end of this session you will be able to
  • Basic understanding of your back
  • Understand principles of safe manual handling
  • Know when to stop!

4
Did You Know ?
80 of people in the western
world are affected with back pain

Manual Handling - Definition
Any transporting or supporting of a load by one
or more employees and which may include
  • LIFTING
  • PUTTING DOWN
  • PUSHING
  • PULLING
  • CARRYING OR MOVING A LOAD
  • which by reason of its characteristics or
    unfavorable
  • ergonomic conditions involves risk, particularly
    of back injury to employees

6
1. LEGISLATION
Safety, Health and Welfare at Work Act
1989 Safety, Health and Welfare at Work (General
Application 1993) Regs.
7
2. AnatomyWhy Is It important?
  • The Musculo-skeletal System of the body is
    designed for movement
  • In order to lift and handle an object safely it
    is essential to have a knowledge of this system
    and its flexibility

8
Spinal Column
7 Cervical
Neck
12 Thoracic
Ribcage
5 Lumbar
Lower back
5 Sacrum (fused)
4 coccyx (fused)
9
Lumbar Spine
  • 5 vertebrae
  • Facet joints
  • Discs

10
Facet Joints
  • Only in Lumbar Spine
  • Gliding movement

11
Spinal cord
  • Down through the centre of the spine we have our
    spinal cord
  • This brings messages to the brain from the rest
    of the body and from the brain to the rest of the
    body
  • Nerves from the spinal cord control the movement
    of the trunk, arms and legs

12
Muscles
  • The spine is strengthened and made moveable by
    muscles.
  • This makes your back flexible as opposed to a
    fixed bamboo like situation
  • Posture muscles are not designed for lifting

13
Spinal Ligaments
  • Ligaments soft tissue in joint capsule. Limit
    mobility.
  • Long Ligaments
  • Limit movement of spine

14
Types of Back Pain
  • There are over 100 accepted causes of low back
    pain (small of the back)
  • Wear and tear being the most common
  • Three types of mechanical back injury which may
    be caused by poor manual handling practice
  • DISC INJURY
  • SOFT TISSUE INJURY
  • BONY INJURY

15
Disc Degeneration - Gradual
  • Nutrition cannot get to disc
  • Disc dries out
  • Lack of nutrition leads to disc degeneration
  • EXPERIENCE A HIGH LEVEL OF PAIN DUE TO PRESSURE
    ON NERVE ENDINGS

16
Disc Pressure
  • When pressure is applied on the spinal nerves
    pain can be felt in several areas
  • Sciatica is caused by disc pressure on the
    sciatic nerve

Pain Distribution
17
Wear and Tear
  • Wear and tear effects can be noticed from as
    early as 25 years of age earlier if there has
    been an injury
  • Heavy physical work over a long period causes
    wear tear
  • Remember we should only lift what we are
    physicaly able to lift at the time of the lift
  • Muscles are strained by over loading or a sudden
    stretch or unexpected movement
  • The more we overdo- the less we can do

18
Ergonomic Assessment
  • Information required to carry out an ergonomic
    assessment
  • THE TASKS
  • THE LOADS
  • THE WORKING ENVIRONMENT
  • INDIVIDUAL CAPABILITY

19
5. Principles of Lifting
  • Assess Task, Area, Load
  • Broad Stable Base (Feet Flat on Floor)
  • Bend the Knees
  • Back Straight (Not necessarily vertical)
  • Firm Grip (Palmer)
  • Arms in Line with Trunk
  • Weight Close to Centre of Gravity
  • Point 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 work
  • Pushing is better than pulling
  • Pushing is easier as you can see over the load
  • If you cant see over the load GET HELP

22
6. Practical application
  • To and from the floor
  • To and from a bench
  • To and from a height
  • Pushing
  • Pulling
  • 2 persons lift

23
Summary
  • There is legislation to help and protect you
  • Being aware of your body and how it works will
    prepare you
  • Being flexible and fit will benefit you
  • Handling loads correctly is the only way

24
Health Safety Office
  • Thank you for your time
  • Remember.
  • nobody is immune to natural wear and tear
  • use it or lose it!
