> Please note that the CSB is not an enforcement agency - they don’t assign fault or levee fines or bring any charges or write any regulation.
So, by that analogy, I think the NTSB is amazing and has done crucial, instrumental work that makes flying safer (as the saying goes, aviation regulations are written in blood). So I think getting rid of the CSB sounds colossally stupid, and I think it's elimination could lead to a willingness by companies to be more careless when it comes to chemical safety.
Safety operationally is regulated by OSHA, based on the MSDS among other things. It isn’t entirely clear where the CSB fits in. There aren’t many surprises in chemistry and OSHA is aggressive.
The safety protocols are pretty straightforward forward and strict, there isn’t much novelty in chemical disasters. Chemical disasters are virtually always for stupid reasons covered by other regulatory organizations.
The examples you mention about MSDS sounds relevant to a large building/warehouse, but we’re talking about massive industrial complexes nearly equal to the area encompassing all of Seattle+Bellevue+Redmond+Renton+Tukwila.
At that scale, there are still plenty of surprises. Like, “oh shit, I didn’t realize the new version of the lubricating oil the manufacturer recommends for our massive pumps have a different additive that reacts with an impurity in our process stream which catalyzes an exothermic reaction”.
I highly recommend a very short book named “What Went Wrong” by Trevor Kletz. It’s surprisingly entertaining and walks you through basic things that have caused disasters at countless chemical plants over and over again.
