SHIFTING LOAD : When a load has to be shifted, you have to take a number of simple steps to prevent back and other muscle strain:
1. If the load is to be manually handled, an assessment of risks should be made.
2. The load should be split down into manageable sizes.
3. Each part should be within the lifting capability of the lab worker.
Generally in Science lab situations, objects are moved through lifting process or using a trolley. Remember that the majority of back injuries are caused by incorrect lifting. Back injuries are the most common cause of injury at work and, range from severe accident to mild discomfort. To avoid back injuries, the back should always be kept straight and the feet apart when lifting.
The following procedure should be adopted:
1. Feet apart. Put one foot forward and to the side of the load. Always keep the feet about a hip breadth apart when lifting as this provides a larger base and will improve your balance.
2. Bend the knees to lower the body vertically to reach the object. Always keep the back straight.
3. Grip the load securely using the whole of your palms and not just the tips of your fingers. This reduces the chances of dropping the object.
4. Keep arms close to your body and, as straight as possible, so that you can use your whole body to carry the load.
5. Keep your chin in. This will lock your vertebrae and prevent injury to the neck.
6. Straighten your legs without jerking and let the strong muscles of the leg do the lifting.
