    • When lifting, use your legs to provide the lift.
    • Take a firm hold of the load, using a power grip (not a pinch grip) whenever possible.
    • Keep the load close to your body when lifting, lowering or carrying.
    • Keep your arms as close to the side of your body as possible.
    • Make all movements as smooth as possible and do not jerk.
    • Make sure the load does not obscure your view.
    • When you lower the load, lower it to your knees and then to the floor (keeping your feet apart and your back straight).
    • Bend your knees when you are working low. Keep your back straight and your knees bent.
