During the Johnson Controls Server Upgrade Project the 7230 A/BSL3 suite experienced an unexplained problem that has caused lab 7230 to become too negative. At this time the lab is safe, but Facilities Engineering is recommending that no A/BSL3 work take place in the 7230 Boon Lab until the issue is resolved. A follow-up message will be delivered once all mechanical systems and room pressures are working in a normal manner.

We thank you for your patience and understanding at this time.
