Management has published its plans for improving ventilation on the Back to Mac website.  Among other measures, they confirmed that any room that has a reading of less than 6 equivalent air changes per hour (eACH) will not be used for classes.

We are asking our members to please verify the list of rooms available on the website. If you see any issues with a room that you will use, please get in touch with us and with your department chair. If your classroom or TA office is not listed, contact your administrator and/or the Union and we will push for a reading. As we hear more and more people concerned with the return to campus, it bears mentioning that the more we contact our departments and management to voice our concerns and dissatisfaction, the more they will need to pay attention to the problems we are facing.
