2. B1004E Compressor Building is Now C-AD’s Only ODH-1 Posted Building  You need ODH-1 training and current ODH -1 physical to enter  You must wear a calibrated Portable Oxygen Monitor (POM) to enter the building  You must first open the door and hold the POM at arm’s length at the building door to verify that the oxygen concentration in the building is safe  You DO NOT need an escape pack to enter, only the POM - it takes no more than ~15 seconds to exit the building (it is small) if your POM alarms  There are always 2 escape packs in the building mounted and labelled on the wall for use if needed  The building is keyed with a lock and only Cryo has the key  This will help ensure that all non-cryo entrants are fully familiar with the entry requirements and with the ODH hazards in this new building 2
