A short Wednesday afternoon update for you on the gas detection system. It seems that both HF detectors in the clean labs have now failed. In order to save your sanity (and mine) from the constant triggering of the alarm or system fault tone on the panel, we have now disabled both HF sensors totally. 

During this time, and as Lindsey said in her previous email, no HF work is to be undertaken until the sensors have been replaced in the new year. 

As always, if you have any questions, then please get in touch :)

Cheers,

Edward
