Good indoor air quality contributes to a favorable learning environment for students, productivity for teachers and staff, and a sense of comfort, health, and well-being for all school occupants. The goal of this kit is to provide clear and easily applied guidance that will help prevent Indoor Air Quality (IAQ) problems and resolve such problems promptly if they do arise. It recommends practical actions that can be carried out by the school staff without the need for training, and is flexible enough to conform to the specific needs of the school. The kit includes an IAQ coordinator's guide, various checklists, IAQ problem solving wheel, and an indoor air pollution guide for health professionals. The coordinator's guide is divided into two basic sections: background information and specific activities. Specific activities involve two major actions: the management of pollutant sources and the use of ventilation for pollutant control. The background information and activities in this voluntary program are directed toward existing schools in the K-12 range, but colleges, universities, and preschool and daycare centers could benefit by application of the principles and activities presented.
