I don't know, but my guess would be that they did whatever OSHA told them to and called it a day. Factories aren't the kind of environment where people take the initiative to improve things, generally. And I bet they told the workers that they comply with all OSHA guidelines (no matter how inadequate they might have been in this instance...) and had a meeting with anyone who had been grumbling.
At least, that was about my experience in very similar circumstances, though I took a bit more initiative to prevent heat-related injuries in the first place. Then we had some slightly uncomfortable meetings where I was told to keep up the good work.
Legal fears largely dominate both common sense and initiative, I fear. It would be nice to be able to just do the right thing without so much worry, but I doubt that will happen any time soon.
I've never had to deal with OSHA. I managed to get them to consult some of our former safety guy's recommendations that they had apparently forgotten about and find some stuff that addressed the heat issues. So they spent a few grand or so on swamp cooler fans to cover areas they should have a long time ago and they got some of those cheap necklaces that absorb water. Those work much better than fans, BTW, though it can be hard to get people to wear them (ironically, I had to badger the one guy who needed one the most and he benefited more than anyone).
A lot of things were forgotten, I guess, because the guy responsible for safety was laid off back in 2008 or something like that, which is probably what made them seem so nervous.
Anyhow, no one got sick from the heat, and this was a downright miserable summer, even by Arizona standards, and we did pretty good from the look of things. Nobody has anything to sue over that I know about. I'm not the type who'd sit back and watch someone get hurt if I could prevent it.
