Indoor Air Quality (IAQ) Basics for Schools

How do I know if there is an IAQ problem?

Diagnosing symptoms that relate to IAQ can be tricky. Acute (short-term) symptoms of IAQ problems typically are similar to those from colds, allergies, fatigue, or the flu. There are clues, however, that can serve as indicators of potential indoor air problems:

• the symptoms are widespread within a class or within the school, potentially indicating a ventilation problem
• the symptoms disappear when the students or staff leave the school building for the day
• the onset is sudden after some change at school, such as painting or pesticide application
• persons with allergies, asthma, or chemical sensitivities have reactions indoors, but not outdoors
• a doctor has diagnosed a student or staff member as having an indoor air-related illness

However, a lack of symptoms does not mean that the quality of the air within the school is acceptable. Symptoms from long-term health effects (such as lung cancer due to radon) often do not become evident for many years. For this reason, schools should establish a preventive indoor air program to minimize exposure of students and staff to indoor air pollutants.

If your child, or someone else you know, is experiencing symptoms that you believe may be related to their school environment, contact a school official immediately. Whether or not the school has a known problem, encourage the school to obtain and use the Tools for Schools Action Kit. This easy-to-use Kit shows schools how to carry out a practical plan of action at little or no cost, using in-house staff.
