Using good lifting techniques is very important. It is also important to pay attention to how you are moving, especially if your work requires lifting and turning, carrying, or stacking.
When turning, be careful to turn the entire body, including the feet. Avoid twisting the upper body to move an item from one spot to another. This is especially important when lifting and turning repetitively.
When carrying objects, keep them as close to your body as possible. Spread your legs and bend your knees (not your back) when lowering heavy objects below the waistline. When stacking, do not exceed your maximum lifting capacity. When stacking overhead, do not hold your breath. Breathe out as you lift up.
By monitoring your own movement patterns, you may be able to see other ways of lifting safely.
