The NIOSH equation determines the recomanded weight limit for lifting tasks, load ports, manual handling without movement. In the case where the load handled is less than the recomanded weight limit, the operators do not run any risk of occurrence of low back pain.
The Recommended Weight Limit defines the maximum weight that can be lifted by nearly all healthy employees during an 8-hour shift without increasing the risk of a musculoskeletal disorder in the lower back.
The NIOSH equation can be used to assess two-handed lifting and lowering tasks, including their impact on the back.
It is especially useful in the case of workers who lift loads whose weight is always the same.It can be useful in any work environment where workers perform tasks of lifting or lowering inert loads (i.e. excluding handling living things) with both hands.
The equation takes into account biomechanical, environmental factors and duration.
The NIOSH equation does not take into account whole-body vibration or the risks of MSDs that are not associated with raising or lowering.
The method cannot be used in the following cases:
Nawo Live is your physical activity risk assessment tool for identifying risk factors for musculoskeletal disorders (MSDs).
