One of the principles of proper body mechanics as it relates to lifting and performing job tasks is power zones. The idea behind power zones is that they define the area around the body in which work is most safely performed. The further outside of these power zones that work is being done the greater the stress placed on the body and the more likely injuries are to occur.
There are 3 Power Zones:
Power Zone 1
Work should be done between shoulder and knee level.
Power Zone 2
Work should be done close to the body.
Power Zone 3
Work should be done in front of the body.
Whenever possible work that is being done should be evaluated to see if it meets safe (green) zones in each power zone. If work is found to be outside the safe zone (red) then modifications should be considered. These modifications can include setting up the work space differently to utilizing tools to accomplish job tasks. The principles of power zones can be applied to physically demanding jobs as well as office work and desk set up.
