The U.S. Chemical Safety Hazard and Investigation Board, or CSB, is a small federal agency with a big name and a singular mission,

The board also produces award-winning animated reenactment videos

which serve as instructive after-action reports.

They've got a devoted following online.

The Chemical Safety Board comes into businesses after there's been a catastrophe, a major

explosion, a fire, a chemical release in situations where workers, neighbors, or first responders

That's right. OSHA and EPA, by law, don't do these sort of root cause analyses.

When I ran OSHA, I would send in an inspector.
