[Celticelement] CELTIC gas detection

Hi everyone, As you may be aware, following the recent fire alarm we discovered the HF sensors, though still working when the engineer tested and calibrated them last Thursday, are coming to the end of their life. As we can not have complete confidence in them, all HF work must stop until the sensors are replaced in the new year. The CELTIC clean labs will still be open for non-HF chemistry. I will let you know when we expect the sensors to be replaced once I have more info from the contractor/Estates. In the interim, the faulty HF sensors are likely to trigger the local gas alarm. Please treat any alarm as a real alarm and immediately vacate the labs. Please ensure everyone working within the CELTIC facility leaves the lab and the 'do not enter' sign is posted on the outer door. Please then contact Edward or myself to check the gas detection system, reset it, and let you know it is safe to re-enter. Thank you for your understanding.
