Pushing and pulling risk assessment
In pushing and pulling operations, the load might be slid, rolled, or moved on wheels. Observe the worker’s general posture during the operation. Figure A9.2 shows some acceptable push/pull postures. The task is likely to be low risk if:
the force is applied with the hands
•
the torso is largely upright and not twisted
•
the hands are between hip and shoulder height
•
• the distance moved without a pause or break is no more than about 20m When do I need to make a more detailed assessment? If the load can be moved and controlled very easily, for example with one hand, you do not need to do a more detailed assessment. You should make a more detailed assessment using, for example, the RAPP tool or full risk assessment checklists (or equivalent) if: • the posture shows that the task requires significant forces, for example, leaning • here are extra risk factors like slopes, uneven floors, constricted spaces or trapping hazards

Aggravating factors The aggravating factors of the lifting operation must be considered which, individually and especially in combination, will enhance the strain on the musculoskeletal system posing a risk of injury and manual handling harmful to health.
Examples of aggravating factors; categorised by the four elements of the TILE principle:
Basic dynamic risk assessment – TILE principle All manual handling tasks should be preceded by a basic dynamic risk assessment carried out by the persons planning to carry out the task before commencing the activity. This can be conducted using the simple and well known TILE approach.
