Intensity refers to#
weight in pounds of items lifted or carried
grip or pinch force of lifted or manipulated items
vibration level /meters:second;1

Alternati,es to lifting
Use carts, hand trucks, hoists, conveyors orother mechanical assistance
Slide ojects instead of lifting them
Store heavy items where you won!t have toend or reach to lift them
Use ladders to get items down from highshelves
