It's another "refinery blows up due to lack of maintenance and half the safety systems fail" episode

Unless you're working with dramatic industrial chemicals, you've probably never heard of the U.S. Chemical Safety and Hazard Investigation Board.

Unlike most federal agencies, these people are, however, very cool.

Apart from their usual work of investigating chemical-related accidents and nagging the industry to up their safety standards, they also put out absolutely kino videos documenting and explaining all sorts of industrial accidents , and the quality of their animations has only increased over the last 15 years.

This is what "disaster documentary" youtubers wish they could be, give this stuff a look.
