(1/6) What is your University doing to reopen in the fall? Here's a place to start (thanks @j_g_allen): Hierarchy of controls:
#1 Elimination of exposure
#2 Substitution of activities
#3 Engineering controls in spaces
#4 Administrative controls
#5 PPE

(2/6) For #1: eliminate exposure by working from home, keeping sick people out of buildings, testing/quarantine/trace. For #2: workers in critical jobs return following all established control protocols including reporting illness (our contractors are using a QR code to report)

(3/6) For #3: establish a risk hierarchy for your buildings. Which one is at low risk? The lab buildings with hoods and 100% outside air and limited occupancy.

(4/6) Which ones are at high risk? The ones that have older equipment that need maintenance and cannot provide 100% OA or additional clean air changes, windows that do not open, higher occupancy (rec centers, dining halls). What to do in these cases?

(5/6) Good question. Target with additional administrative controls (see #4) and/or additional well designed proven technologies such as HEPA air purifiers and germicidal UV. limit occupancy or close.

(6/6) For #4: De-densify workspaces and institute physical/social distancing. For #5: WEAR masks. mandatory, full stop. everywhere. Thanks to @CUBoulder for working on a plan that addresses all of these controls and to @j_g_allen for his webinar this morning

Oh and one more thing. Pay attention to your bathrooms. flushing the toilet generates airborne droplets. Virus has been found in wastewater (and active), most institutional toilets do not have covers, so run exhaust 100% of the time and clean often.
