Lifting and Carrying (Manual materials Handling)


Problem:

Workers who unload and stock metal sheets and coils may face hazards from lifting and carrying (manual materials handling).


Risk Description:

Lifting heavy materials while unloading and stocking metal sheets and coils can cause injury to the muscles, discs and ligaments of the low back.  Non-specific low back pain is not the result of a fall or some other acute traumatic injury, so it can be difficult to identify a specific event that led to the injury.  Repetitive lifting can lead to low back strain, muscle strain, ligament sprain, a bulging or herniated disc, nerve damage, or other back problems.


Assessment Info:

Liberty Mutual has published tables on their website that can be helpful in determining maximum acceptable weight limits for lifting and carrying tasks along with suggested solutions for minimizing the risk of injury from lifting or carrying. Washington State LNI additionally has useful tables that can assist in determining weight limits.
