Object Handling Awareness

TI CMPP:LOAD 0070/09

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.


 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


Can you identify with these
common causes of musculoskeletal
injury/pain?
 Cumulative strain
 Repetitive strain
 One off incident?


Manual Handling Operations
Regulations1992
TILEO Risk Assessment
Take a typical handling situation at
your place of work and
consider………….


 the Task
 the Individuals Capability
 the Load
 the Environment
 the Other factors, such as attire,
systems of work and equipment

Provision & Use of Work
Equipment Regulations 1998


Risk Assessment
The idea is to
 Avoid
 Assess
 Reduce
 Inform


Biomechanics
The Spine


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


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

25 to 35cm

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 CMPP:LOAD 0070/09
TI

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

Adopt and adapt the principles according
to you!
Stop and think
Keep close
Stable position
Avoid stooping
Use a secure hold
Avoid twisting
Lead with the head
Move smoothly
Vary positions
