In 1995, the U.S. Environmental Protection Agency (EPA) released the highly successful Indoor Air Quality (IAQ) Tools for Schools (TfS) program. The TfS program is an in-the-trenches approach that empowers teachers and other school employees to help improve IAQ in the learning environment and reduce building occupants’ exposure to indoor environmental contaminants. As a supplement to the program, a nonprofit health affiliate of the National Education Association, the Health Information Network (HIN), has developed resources along with a series of hands-on, interactive lessons.
