Ergonomic improvement in a roll-forming station for a metal-mechanical company

The present research seeks to design and implement an ergonomic improvement in the roll-forming station of a metalmechanical company, where the incidence rate for low back pain is 29.4%. The methodology used to evaluate the
situation prior to the improvement was the NIOSH equation, where the risk of injury was found to be 3.30 at the origin
and 3.57 at the destination. According to NIOSH benchmarks, these factors constitute a high risk of injury and urgent
intervention. Following the design and implementation of the improvement, the NIOSH equation was again used to
demonstrate the decrease in risk presented by the operation. An improvement of 81.5% in the rate of lifting at the
origin and 73.4% at the destination was achieved. The research presented validity in the NIOSH equation, helping to
corroborate the effectiveness obtained by the design and implementation of an ergonomic improvement, thus reducing
the probability of injury,and increasing job satisfaction.
