Leaks are a routine part of life if you live near chemical facilities ("the smell of money"). They have various strategies to avoid it, but it takes investment and since everyone slashed spending during Covid (and a lot of companies before that too), it's decaying.

An increase in accidents wouldn't surprise me given the amount of job-hopping - lots of new people equals lots of mistakes. Plus I'm sure a lot of them are chasing overtime like mad which makes things worse.
