Construction activities that involve manual handling present a significant risk of Musculo-Skeletal Disorders (MSDs).
A MSD is an injury that affects the muscles, joints, tendons or spinal discs.
Such injuries are most likely to affect the back, shoulders and neck, and legs.
Symptoms may include pain, aching, discomfort, numbness, tingling and swelling.
Construction workers suffering from MSD have a reduced ability to do tasks, as well as pain or discomfort; serious cases can result in permanent disability.
The construction industry has one of the highest rates of MSDs.
There are no absolute safe weights to lift/move by hand. The guidelines provide advice on lifting weights at various horizontal and vertical locations from the body.
It is worth noting that a conventional concrete kerb weighs almost 70kg (when dry) compared with a plastic krb that weighs about 6kg (91% less weight).
