What are the approximate guidance weights for lifting at shoulder height for males using short levers?

The approximate guidance weights for lifting at shoulder height are critically determined by factors such as the use of short levers and the biomechanics involved in manual handling. In the context of lifting at shoulder height, it is essential to consider that the weight should be manageable to minimize the risk of injury, particularly as the shoulders are less stable compared to the lower body.

The range of 10-20 kg is seen as a safe limit for males when using short levers, as this weight range allows for adequate control and reduces strain on the upper body and spine. Short levers, such as having arms close to the body, can assist with lifting; however, higher weights increase the risk of improper lifting techniques and potential musculoskeletal injuries.

Understanding the guidance weights helps individuals make informed decisions about manual handling tasks and encourages the adoption of safer lifting practices.
