I love these guys videos. From the U.S. Chemical Safety Board, a government agency.

It’s like Seconds From Disaster, but without all the unnecessary melodrama. And it’s all explained in such a way that even a layman such as myself can clearly understand how and why things happened.

These guys are the real heroes here.
