If you have indoor air quality (IAQ) concerns in campus buildings including noticeable odors, dust in the air, or physical symptoms such as allergies, headaches, nausea, etc. please be sure to fill out the IAQ questionnaire/complaint form at https://protect.iu.edu/machform/view.php?id=38356 so that the issue can be investigated and managed accordingly. For further information, you can view the IAQ Program at https://protect.iu.edu/doc/environmental-health/IU%20Indoor%20Air%20Quality%20Program%20.pdf. In addition, please note that essential oil diffusers and wax warmers, while they may smell nice, contain chemicals and irritants that can cause negative reactions for some.
