The objectives of this tool include:-providing a tool for operating crews to identify opportunities for latent conditions and human error, and-improve how Process Hazards Analysis/Hazard Evaluation/Revalidation process address human factors.The scope of this tool includes existing operations and equipment and human tasks. This tool is intended for use without specific training on human factors. This is a simple process for gathering a few operators and mechanics who are familiar with the equipment/process and who are qualified to identify where traps (latent conditions) in the equipment and tasks (error likely scenarios) exist that make it easy for people to do something wrong.
