Indoor Air Quality (IAQ)

Indoor Air Quality refers to the air quality within and around buildings and structures, especially as it relates to the health and comfort of building occupants. To ensure a healthy work environment, EH&S will respond to and investigate all odor or air quality concerns to identify potential sources.  

EH&S investigates all odor or air quality concerns to identify potential sources and determine if the issue is rooted in laboratory practices or stems from building infrastructure. In cases where the source is laboratory related; EH&S provides the necessary corrective guidance to personnel.    

Reports related to building infrastructure and maintenance, such as odors from painting, drilling, or roof work, as well as issues of thermal discomfort (e.g., rooms being too hot or too cold) should be routed directly to Facilities via the call center.

Do not ignore persistent odors. Early reporting allows for prompt investigation and resolution. 

Once a recurring issue is identified, it is the responsibility of the space occupants to maintain an odor log. Follow up directly with Facilities for updates on long-term mechanical investigations. A standardized log template is available to download here.

Notify EH&S if the intensity or nature of the odor changes. 

Reports related to building infrastructure and maintenance, such as odors from painting, drilling, or roof work, as well as issues of thermal discomfort (e.g., rooms being too hot or too cold) should be routed directly to Facilities via the call center.
