Humantech has released a new mobile app based on the popular NIOSH Lifting Equation, which was created in 1991 to help recognize physical stressors associated with manual material handling and lifting tasks. The HT NIOSH Lift Calculator for the iPad and iPhone quickly and effectively calculates the risk associated with manual material handling tasks. It can evaluate both existing and proposed lifting conditions to determine the recommended weight limit for a specific task, and it can identify those jobs that might require ergonomic intervention. The app, available in both metric and standard measurement, can be purchased on iTunes.
