Often, poor planning of the work flow results in needless or repeated handling of the same object. When articles are temporarily stored in one place, moved to another, stored again, and moved again, a more efficient work flow can eliminate many potentially harmful MMH tasks. Consider using powered or mechanical handling systems if eliminating MMH tasks completely is not possible. Mechanical aids lower the risk for back injury substantially by reducing the worker's physical effort required to handle heavy objects. Manual handling such as lifting and carrying can be easier and safer if mechanized by using lift tables, conveyors, yokes or trucks.
Gravity dumps and chutes can help in disposing of materials.
Mechanical aids also reduce the need to select workers for the task, but it is essential that the worker is properly trained in the safe use of the available equipment. If mechanical aids cannot eliminate manual handling, decrease the MMH demands. Reduce the weight by assigning two people to lift the load or by splitting the load into two or more containers. Using light plastic containers also decreases the weight of the load. Change the type of MMH movement.
