All, As part of the building maintenance activities this week, we will be conducting a test of the Toxic Gas Monitoring system. Before the test begins, the standard announcement to disregard the alarm will be given. Remember, this is only a test. At the conclusion of the test, another announcement will be made communicating that the TGM system is back on-line. Thank you for your support and cooperation.
