Bending your knees will allow you to lift with your legs and reduce the load on your lower back. Grip the load securely Get a secure handle on the object before you lift to avoid slipping. If a load does start to fall away from you, let it go. You can do enormous damage to your back if you attempt to catch a heavy object in an awkward position. Lower the load in reverse All the effort put into a proper lift will be erased if the load is lowered by bending at the waist and putting pressure on the back.
Back belts provide no protection from back injuries.
EHS does not recommend the use of back belts for such purposes.
