AH 3574 Lecture Notes - Lecture 8: Relative Risk, Soft Tissue
Document Summary
Lifting, lowering and/or transporting of materials of various sizes and shapes using the hands, and without utilizing mh equipment. Risk targets are primarily the lower back and shoulders. Soft tissue injuries associated with tendons, muscles, nerves, discs, ligaments. Eliminate manual lifting/lowering of high risk tasks, and reduce other at risk tasks. Reduce frequency and severity of injuries resulting from lifting/lowering. If manual materials handling (mmh) must be performed. Tools are available to determine for a given set of conditions whether a particular manual lifting task presents an increased risk of injury to the lower back. Tools are only tools and their use does not guarantee that a back injury will or will not occur. Widely accepted as a useful tool for calculating biomechanical stress on the lower back. Used to rank order (prioritize) the relative risk of lower back injury for a given set of lift conditions. Exceptions on use of the niosh lifting equation.
