your insurance pays out in the event of an accident.
In the United States, worker's compensation insurance is no fault - the worker gets something whether or not the employer did anything wrong/was negligent. Damages are from a table ($X for Y injury, no punitive damages). The employer's compliance with OSHA is mostly irrelevant in terms of payments to the worker.
I think that the conversation with your fire insurance company about the damage to the equipment / building would involve OSHA compliance issues and fire code issues, though. I suspect (but do not know) that the future cost of both that and workman's comp insurance will depend on such things, even though the current payout for events that already happened doesn't.
The article can be found here. While it is not, for many of us, new ground, it is an excellent treatment, and it requires no rationalist background in order to be understood. The subject is the pernicious pull of doing the standard thing, regardless of whether or not the standard thing makes any sense, and it does us the service of giving that phenomenon a descriptive link we can share as well as an excellent name.
I hope to, after more discussion and thought, write a main post on the subject.
