Facilities Engineering is in the process of investigating this issue.  A follow-up message will be delivered once all mechanical systems and room pressures are working in a normal manner.

Revised:  As of 11:45 all HVAC systems have returned to normal operation and all A/BSL3 or BSL3 alarms have returned to normal.  All activities may resume in the affected areas.
