How can we keep track of potential IAQ problems at our company?

It is often difficult to determine if symptoms are a result of exposure to poor IAQ or some other factors, however, the following information may be helpful to figure out if there is an IAQ problem at your facility:

• Do employees have symptoms that just occur at work and go away when they get home?
• What are these symptoms?
• Are these symptoms related to a certain time of day, a certain season, or certain location in the workplace?
• Did the symptoms start when something new happened in the workplace, such as renovation or construction projects?
• Are there other employees at work with similar complaints?
• Did any employee see a doctor for their symptoms, and if so, did the doctor diagnose an illness related to IAQ?

If answers to the above questions indicate a possible IAQ issue, an effort should be made to identify indoor air sources at the worksite that may be possible causes.
