What kitchen temperature would be considered an unsafe working environment?

I work at a restaurant in the southeastern US and our ac has been broken for a month or 2, management put off calling in to get it fixed for that whole time and then this past week I came in for a night shift and was told that maintenance had come in that day talking about there's nothing they can do and management had nothing else to say. It gets something like 95 degrees on the line and it's the middle of summer, is there anything I can do?
