The cause of the accident, which affected 153 workers and sent 32 to hospital, was revealed by the US Chemical Safety Board (CSB) in a safety bulletin published in January.
The publication is now supported by this newly-released seven-minute safety video, entitled Shock to the System, which includes a detailed 3D animation of the events that led up to the accident.
Chairperson Rafael Moure-Eraso said, “The CSB’s new safety video is a valuable tool intended for use at the large number of facilities that utilise anhydrous ammonia. The key lessons learned from our investigation – examined in our report and in this video – can help facilities prevent a similar accident from occurring due to hydraulic shock.”
