The Shift Supervisor should inspect the PLC type EtO monitoring system at the beginning of every shift.

Check for the following items:

Is the Power On lamp illuminated?

Is the PUMP ON LED illuminated, and does the flowmeter indicate a flow rate of 0.5 liter/minute?

Does the EtO concentration display indicate a reading of zero or above?


If the answer to any of these questions is “no,” call Clinical Engineering or Maintenance to remedy the situation.
