Manual handling in the workplace - what you need to know

Manual handling in the workplace - what you need to know

How do I know if my staff are at risk of strain injuries from their daily routines?

It’s a matter of judgement in each case, but there are certain things to look out for, such as people puffing and sweating, excessive fatigue, bad posture, cramped work areas, awkward or heavy loads, or people with a history of back trouble. Operators can often highlight which activities are unpopular, difficult or hard work.

It is difficult to be precise – so many factors vary between jobs, workplaces and people. But the general risk assessment guidelines in the next section should help you identify when you need to do a more detailed risk assessment.

Figure 1: Manual Lifting and Lowering for Men and Women

  • Use Figure 1 to make a quick and easy assessment. Each box contains a guideline weight for lifting and lowering in that zone. (As you can see, the guideline weights are reduced if handling is done with arms extended, or at high or low levels, as that is where injuries are most likely to happen.)
  • Observe the work activity you are assessing and compare it to the diagram. First, decide which box or boxes the lifter’s hands pass through when moving the load. Then, assess the maximum weight being handled. If it is less than the figure given in the box, the operation is within the guidelines.
  • If the lifter’s hands enter more than one box during the operation, use the smallest weight. Use an in-between weight if the hands are close to a boundary between boxes.
  • The guideline weights assume that the load is readily grasped with both hands and that the operation takes place in reasonable working conditions, with the lifter in a stable body position
