<p class="MsoNormal"><span style="color:#1F497D">To Denis Grimards point about TGMS points, we’re either going to move the Hydrogen generator to the interstitial space above the point of use (shortest distance possible) or a wall mount near the non-toxic gas
distribution panel. The TGMS is not yet completed , so we’ll design “ tank like” shut offs at the generator (orbitally welded connections). This also moves a non-rated piece of equipment out of the HPM room (the unit is UL rated, not NEC Class 1 Division 2).

<p class="MsoNormal"><span style="color:#1F497D">To Bills point about H2 in cabinets, it’s a good question whether its required by the state or just “best practice”. AGI specified as being in a gas cabinet in our design, every facility in Massachusetts I have
worked (3 private) has had it in gas cabinets. NFPA 55 says that the exhaust cannot be recirculated for Hazardous Gases.<o:p></o:p></span></p>

<p class="MsoNormal"><span style="color:#1F497D">Excellent suggestion. To add to Bill’s recommendation, usually, when we install flammable gas cylinders with regulator or gas panel without an exhausted enclosure, we expose mechanical connections to the open
space. If this is the lab/fab strategy, then we recommend installing LEL/flammable gas sensor in the vicinity with horn/strobe and manual pull station. Usually the AHJ will require monitoring in this situation.<o:p></o:p></span></p>

<p class="MsoNormal" style="margin-bottom:12.0pt">Thomas,<br>
While I have had excellent experience with Proton Systems <br>
and recommend an H2 generator to minimize bottle changes,<br>
I know of no requirement to keep H2 in a gas cabinet.<br>
Your local authority may impose a different requirement.<br>
<br>
On site hydrogen generation with a PEM strategy rather than<br>
a potassium hydroxide system - in a facility that already has<br>
excess high quality DI water and excess electrical capacity<br>
(as our labs usually do) makes sense. It takes some time to <br>
recover the investment - if it is not being compared to a gas cabinet.<br>
<br>
I ask that the discussion address which labs keep H2<br>
in a gas cabinet and why. There are arguments against keeping H2<br>
in a gas cabinet rather than having it open to lab air where the air<br>
changes per hour are significant and offer their own safety.<br>
