The Micro/Nano Technology Center at the University of Louisville has the
same protocol.  We do not turn off our cylinders, but they controlled by our
gas cabinets and TGMS system.

 

Cheers!

Thank you so much everyone for such an enthusiastic response.  It seems
clear that at most facilities (if not all), the gas cylinders are always
kept open. We also have TGMS in our cleanroom which allows monitoring of the
toxic gases at multiple locations (source and delivery point) and will shut
off the ESO valve in the event of a leak. 

We will work with our safety and ES&H teams to change our current practice
of turning off the gases when not in use.

 

Regards,

Manish

Happy Friday everyone,

 

I have a question related to toxic gases in our nano fabrication center.

 

We typically shut off our toxic gases at the source when not in use, using
the in line valves on the Safety Manifolds, the ESO valves, and the cylinder
valve. This is to comply with the administrative control stated in our gas
safety notes. The following question came up for toxic gases. I would like
to understand how this is being done at other facilities and the reasoning
behind it.

 

"Is there a good reason we turn off the toxic gases at the end of the day
instead of just leaving them on? It seems like if there is a risk, it would
be wear and tear on the valves etc, plus someone going in vault often to do
it."

 

 

Thanks in advance,
