At approximately 12:01 am there was a room pressure alarm for room B127. At this time no work should take place within this lab. Facilities Engineering is in the process of investigating and recovering the room. A follow-up message will be delivered once all mechanical systems and room pressures are working in a normal manner.
UPDATE: The room pressure in B127 has been stabilized and maintaining normal pressure. Work may resume in B127. A follow up outage will be scheduled for the B120 suite to replace a component in the exhaust air valve serving B127.
