light bulb Avoid lifting from the floor whenever possible. If you must lift from the floor
do not bend at the waist. The techniques shown below help the worker to keep the
spine in a safer position while lifting from the floor.

Team lifting can reduce the load in half. Discuss your lifting plan so you don't make surprise movements.

 

light bulbUse a scissors lift, load lifter, or pneumatic lifter to raise or lower the load so that it is level with
the work surface. Then slide the load instead of lifting.
