All delegates will gain an awareness of risks associated with
manual handling and of the measure they must take to reduce
injury to both themselves and others.
TI CMPP:LOAD 0070/09
identify legislation related to manual handling
demonstrate ability to calculate the risk level of a manual handling activity
basic understanding of biomechanics practise principles of movement
TI CMPP:LOAD 0070/09
Can you identify with these common causes of musculoskeletal injury/pain?
Cumulative strain Repetitive strain One off incident?

TILEO Risk Assessment
Take a typical handling situation at your place of work and consider………….

Biomechanics
The Muscles of the back and abdomen
Provide stability for the spine
Control spinal movements
Protect the vertebral coloumn

Biomechanics
Mechanical loading of the spine When upright load on spine arises mainly
from effects of gravity When leaning forward tension in the back and
hips increases causing increased load on the spine
When the trunk is horizontal loading on the spine stems almost entirely from back muscle tension-this can be calculated
TI CMPP:LOAD 0070/09
Biomechanics
When the trunk is horizontal Centre of back muscles to centre of motion 5
to 6 cm Lumbar Sacral disc to centre of upper body
mass 25 to 35cm Leverage = 6 to1 For 30kg upper body mass = 180kg force If you lift extra load of 30kg lifted in this
position force then =360kg

Biomechanics
Static Loading causes a creep effect on the discs – Kazarian (1975)
Therefore avoid holding even light weights :-
For long periods In a stooped position Whilst leaning forward At arms length
TI CMPP:LOAD 0070/09
Biomechanics
Feet must be in the correct position
Slightly apart an offset
Pointing in the direction of travel
Keep loads within the shaded area when handling
TI CMPP:LOAD 0070/09
Adopt and adapt the principles according to you!
Stop and thinkKeep close
Stable positionAvoid stooping
Use a secure holdAvoid twisting
Lead with the headMove smoothlyVary positions
