NIOSH Lifting Equation

Low Back Injury Prevention and the NIOSH Lifting Equation

Course Summary:
Low back injuries represent a significant problem to industry.  As the Federal Agency responsible for conducting research and making recommendations for the prevention of work-related injury and illness, the National Institute for Occupational Safety and Health (NIOSH) recognized this, and in 1993 developed an evaluation tool called the NIOSH Lifting Equation.  The equation is fairly straightforward requiring the user to input a variety of information describing the lifting task (e.g. how far the load is away from the body, how frequently the lifts are performed, how far off of the ground the load is, how much the person needs to twist their spine to perform the lifting).  The equation then provides an evaluation of this lifting task and describes the relative risk of the task.

Course Highlights:

  • Introduction to basic spine biomechanics
  • Concepts of basic statics
  • Factors of low back injury
  • Risk calculation
