We don’t know yet what caused the explosion and fires at the Superior, WI oil refinery. The U.S. Chemical Safety Board (CSB), an independent, non-regulatory federal agency, is investigating the incident and it could take weeks to months before the causes of this incident become public information.
What Andre Da Costa, Herbert H. Dow Chair in Chemical Process Safety at Michigan Technological University, says he can tell you is that incidents like this – with an uncontrolled release of energy and chemicals with the potential to cause injuries to the employees and the public, damage to the environment and to property – can be prevented by effective implementation of risk-based process safety principles.
