Post by: westerner on October 19, 2012, 10:44:16 PM

Has anyone heard of any incidents where hard drives have been corrupted following a gas discharge in EDP environments?

I do remember there was concern 'back in the day' of the risks of thermal shock from CO2, hence the wider use of BCF/BTM in computer environments.

With current agents the following links will be of interest:

This could be a major issue in Europe where the HCFC blends are intended to be phased out by the EU, leaving only inert gases & water mist for data centres
