It’s on a level of the building that’s adjacent to the loading dock (which itself is underground, accessed via ramp directly from the street). I recall that it’s on a mezzanine level of the nano complex and there was clever massing of the building that enabled siting of the bunker one level below grade. I was not privy to details before construction, involved in permitting or working with the AHJ.<div class=""><br class=""><div class=""><div><blockquote type="cite" class=""><div class="">On Dec 7, 2017, at 9:19 PM, John D Shott <<a href="mailto:shott@stanford.edu" class="">shott@stanford.edu</a>> wrote:</div><br class="Apple-interchange-newline"><div class="">

<div class="">The institution for whom I used to work had a below-grade gas bunker in 1985 … when that was still legal. </div>

<div class="">In 1995, we constructed two at-grade bunkers: one for toxics, flammable, and pyrophorics and one for corrosives. </div>

<div class="">The one in which the silane lives has very heavily reverted walls, blast resistant doors, and a flimsy louvered ceiling … with no occupied spaces above or adjacent. </div>
<div class=""><br class="">
</div>
<div class="">Our AHJ would NEVER, EVER want us to have silane below grade. Despite my status as a leather-helmeted old fart, neither would I. </div>

<div class="">There are likely online photos of silane "releases" that are quite persuasive. </div>

<div class="">In our case, an installation below grade may be preferred. I am wondering if anyone can provide any insight into the reasoning behind this. Does anybody store/use Silane below grade?</div>
