anyone know what the OSHA regulations in iowa are on how cold of a temperature you can work in are?

its getting really cold in my work, i work in a freezer and i was wondering if they were allowed to even do that.

http://www.iowaworkforce.org/labor/iosh/ Here's Iowa's OSHA page. I searched a few of the likely documents for 'temperature' with no result. You may pop an e-mail to one of the folks on the contact page. That's probably the easiest way to get the right information. Be sure to ask them to cite the resource, so you can print a copy for yourself.
OSHA has several pages on the subject, but unless you are getting near frostbite, it will be within the rules. Many people work in freezer environments, it is just wearing the proper clothes. Now glove regulations may come into play.
