About the Webinar:
Many ergonomic evaluation and risk assessment tools have been around for decades, and were designed to evaluate single or mono-task work. In practice, there are few single-task jobs. Most work is multi-task, exposing the worker to ergonomic risk factors of different levels (i.e., forces of different magnitude, postures of different severity, etc.). This presentation will review a timeline of the evolution of ergonomic assessment tools, and describe how tools are rapidly transitioning from single-task to multi-task models. Newer multi-task models such as Auburn University FFT (Fatigue Failure Theory) and RCRA (Recommended Cumulative Recovery Allowance, Gibson & Potvin 2016) offer tremendous advantages over earlier single-task models. These advantages include the ability to calculate job rotation path exposures, calculate cumulative daily exposure limits, and determine the contribution of each task/step to the overall risk/evaluation metric. New multi-task models also experience tremendously less model error than older single-task models. Learners will review model error through practical examples, and learn to apply Rules for Tools, a design taxonomy for developing new tools, and a basis of evaluation when comparing existing tools.
