pollutants. The hypersensitivity diseases most clearly associated with indoor air quality are asthma, rhinitis, and hypersensitivity pneumonitis. Hypersensitivity pneumonitis is a rare but serious disease that involves progressive lung damage as long as there is exposure to the causative agent.

HYPERSENSITIVITY PNEUMONITIS: A group of respiratory diseases that cause inflammation of the lung (specifically granulomatous cells). Most forms of hypersensitivity pneumonitis are caused by the inhalation of organic dusts, including molds.

lAQ: Indoor air quality.

lAQ BACKGRQUNDER: A component of the lAQ Tools for Schools Kit that provides a general introduction to lAQ issues, as well as lAQ program implementation information.

lAQ COORDINATOR: An individual at the school and/or school district level who provides leadership and coordination of lAQ activities.

lAQ CHECKLIST: A component of the lAQ Tools for Schools Kit containing information and suggested easy-to-do activities for school staff to improve or maintain good indoor air quality. Each Activity Guide focuses on topic areas and actions that are targeted to particular school staff (e.g..
