First step is Cooling
See the video below go over "Osha Quick Card" some highlights of their massive rulebook on keeping workers safe and specifically heat stress.
What Can I do?
If you're too hot, then you know your people out on the shop floor are burning up. Come up with a plan to have "cool rooms" or cooling stations where your people can find some relief.
Not only is it the law, you will have more productive workers that know you care about them. Take a look and note the first step is portable/temporary cooling.
