I was specifically thinking about historical methods for asbestos installation. I don't know the numbers exactly. I know that modern methods for handling hazmats like asbestos are good enough that it's basically not a risk factor. However, I suspected, based on the lack of "My grandfather got X and died" stories, that even old-timey asbestos handling protocols did not have a particularly huge rate. A visible rate, yes, but not something like coal mining sans PPE, mercury, or tritium, where the occupation effectively guarantees your cause of death. I chose asbestos because it was the most visible example that came to mind of something that had a relatively low rate but that most people would agree needed to be shut down for the health and safety of the workers involved with it. I'll note that the "lifetime risk" numbers in the first response are almost certainly historical. I'd expect the studies he's looking to have been published around the time modern handling standards were developed, and they may have even contributed to their implementation. The symptoms also take decades to manifest, so I'd expect modern rates to be good indicators of the safety of the industry circa 20-30 years ago and nearly useless for indicating modern standards. 50 years ago probably not, but 20 years is probably still good.
