The Indoor Air Quality - Tools for Schools Action Kit for Canadian Schools, March 2003 version was prepared by the Indoor Air Quality working group of the Federal/ Provincial/Territorial Committee on Environmental and Occupational Health (CEOH-IAQ). This kit provides a process and the tools to help schools prevent, identify, assess, and address the majority of indoor air problems with minimal cost and involvement. This can be accomplished by using trained professionals to perform the limited and well-defined set of basic operations and maintenance activities that are explained in the kit. It is recommended that implementation of the IAQ Tools for Schools program be started early in the school year.
