WISHA stands for Washington industrial safety and health act. Simple ergonomic risk assessments on large types of manual lifting and lowering tasks can be done using this WISHA lifting calculator. It requires actual weight, the vertical position of hand, horizontal position of hand, lifts per minute, hours per day and twistings as input. Except for actual weight, all the inputs are selected from drop down lists. Twisting angle should be either above 45 degrees or below 45 degrees.
This WISHA lifting calculator in this page will be a useful one for the companies of Washington to ensure employees safety on manual lifting tasks.
