Back in the 70s when I worked as a Loss Control Engineer for an insurance company. The company insured grain elevators and feed mills.
One day I got a inspection request to check out a feed mill that a local agent wanted to insure. To my surprise the feed grinding and handling equipment was all run by flat leather belts powered by a water wheel from a dammed up stream.
Needless to say there was nothing OSHA or NFPA approved about the place. Coverage denied! The feed mill went out of business shortly thereafter. I think that was more about the 80 year old owner/manager deciding to retire than any insurance coverage issue.
