"
In its preliminary investigation, the UC Center for Laboratory Safety, considered a national leader in laboratory safety, determined that the explosion was an isolated incident and not the result of a systemic problem."
I'd say I'm skeptical of this conclusion while also admitting, in all fairness, that most universities likely would have had difficulty putting together a qualified review team to vet this setup or even knowing what expertise should be represented -- even though a hydrogen explosion is the focus of attention and is the most probably cause of this incident, there are other tank failure modes that should have been evaluated prior to startup as well. I'll readily admit that my institution does not have a process to ensure that something like this would get a proper design and operational hazard analysis. It is totally up to the PI to request assistance and pay for outside consultation, if needed.
