BNC All On 12-19-06 at 12:15 P.M. we will slow down the make up air to the east lab wing for about ~30 - 45 minutes to replace a failed temperature sensor. This will effect the positive pressure for all east wings lab to where the door may be hard to open during the repairs. Thank you for your cooperation.
