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. </p>

teams to change our current practice of turning off the gases when not in use.</p>
