[labnetwork] Automated Emergency shutoff valve

[Matthieu Nannini, Dr.]

Dennis,

Yes. All are in exhausted gas cabinet. When I presented the safety mechanism to the project manager here, showing him the shutoff valve in the pigtail just before the panel, he mentioned that there was still a weak point between this valve and the actual cylinder rotary valve itself. If a leak occurs at the rotary valve or the CGA/DISS connection or at the pigtail nothing can stop it. Hence the shutoff valve on the cylinder rotary valve idea from the project manager.

Matthieu,

are you using gas cabinets to house your HPM cylinders?  If so, why wouldn't you use the shutoffs in the cabinets to perform this functionality?

Collegues,

Our facilites dept. is reviewing our operations before a « used-to-be-not-so-major » renovation. They are flirting with this idea of installing Emergency Gas Cylinder Valve shutoff like sold by the following company: http://www.halogenvalve.com/
These valves would be hooked up to our TGMS.

Any of you has such an installation ? Anyone could comment ?

Thanks
