How can I find out about the air quality in my workplace?

Test kits. There are many different kits that one can buy to test indoor air quality. I trained at a great respiratory center in denver, co, and they have a kit that works well. Here's a link to the site where you or your workplace can purchase a kit: http://www.Nationaljewish.Org/familyaircare/ the kit is mailed back to the medical center in denver, and the results are sent back to you. It's a great kit!
Air quality. You can ask your employer about the air quality. Check this site: https://www.Osha.Gov/sltc/indoorairquality/faqs.Html.
