Due to the vast number and complexity of buildings at The Ohio State University, a wide range of working conditions exist. The quality of indoor air within OSU buildings should allow employees to work safely at all times. However, there are rare circumstances where hazards, such as elevated particulates (dust, dander, and allergens), volatile chemical vapors, vehicle emissions, mold, etc. may enter workplace air. EHS has the capability to conduct air monitoring for these, and many other, compounds to evaluate breathing air within a building.
