Heat Stroke is a very serious matter folks. Especially to those who work outside or in an open door environment, which includes those shops who just lift their sliding doors open when it's hot.
OSHA doesn't have regulations directly regarding Heat Illness....but the OSH act does cover is issue. It states you are required to have a Heat Illness & Injury Prevention Program training if you are exposed to the open door work environment or work directly outside. The rules come into play with temperatures over 80 degrees....but remember, the actual Heat Index is adjusted for humidity and wind. So it could be very much hotter than the thermostat shows....which can cause heat exhaustion and could lead to heat stroke.
Please refer to the following article which shows what happens when you don't know what to do in mitigating heat illnesses:
For people working outdoors in hot weather, both air temperature and humidity affect how hot they feel. The "heat index" is a single value that takes both temperature and humidity into account. The higher the heat index, the hotter the weather feels, since sweat does not readily evaporate and cool the skin. The heat index is a better measure than air temperature alone for estimating the risk to workers from environmental heat sources. You can also refer to OSHA's Heat Index page at:
