Impact of Human Factors on Operator Response to Alarm: Lessons from Process Industry Incidents
Recording Date: March 2021
According to numerous industry studies, human failure contributes to upwards of 80% of industrial accidents. New incidents continue to occur that bear a striking resemblance to previous incidents. This means we are not effectively learning from history. The purpose of this webinar is to review selected process industry incidents where operator response to an alarm was a contributing factor. It will examine the incidents through the lens of Human Factors Engineering to seek new insights and lessons learned to improve operator performance. The presentation will identify the possible type(s) of human error (slips, lapses, mistakes, or violations) for each incident and review how cognitive biases, situation awareness demons, and mental model failures may have contributed to the operator’s response.
