From helenandersonpenn at gmail.com Mon Jan 23 12:30:19 2012 From: helenandersonpenn at gmail.com (Helen Anderson) Date: Mon, 23 Jan 2012 12:30:19 -0500 Subject: [labnetwork] lab security survey Message-ID: Folks, A group of us are working toward a security presentation for UGIM 2012 this summer. Toward that end, we have two brief surveys for micro/nanofabrication lab users, staff, faculty, health & safety, security and facility managers. The first is anonymous*, asking about your views on security issues. The second enables you to request specific security information if you want it, either at your site or at the conference, and asks for your name and affiliation. Total time to fill out both surveys is about 10 minutes. Here are the survey addresses: https://sasupenn.qualtrics.com/SE/?SID=SV_1z6L1IMOpkKDamg https://sasupenn.qualtrics.com/SE/?SID=SV_bxcKhc43MIuOb64 Participants: Helen Anderson, University of Pennsylvania David Bunzow, Lawrence Berkeley Lab Abbie Gregg, AGI John Hughes, University of Illinois Justin Kita, FBI WMD Chemical Countermeasures Unit Richard Morrison, Draper Lab One area that we are *not* working on is the safety of nanoscale particles. I hope someone else will present on that topic this summer. Thanks for your participation. -Helen Helen Anderson *anonymous means that no individual identities will be collected or presented at the conference. However, as in all web activities, your IP address will be collected. If you have any concerns about that, you can use a free public network such as a coffee shop or library for the first survey.

The product was developed as a zero flame spread material to replace plastic and is required by major insurance underwriters. This duct material is referred to as PSP and it is made of stainless steel with a Teflon coated interior to resist the corrosion from strong acids. PSP is notoriously expensive and cannot be reworked in the field, therefore the measurements need to be accurate before fabricating. Any metal exhaust can be used for pyrophorics if local and state ordinances are adhered to. I suspect that the downstream exhaust is PSP and the proposal is to maintain the integrity of the system. We here at Harvard use PSP materials for any modification or new addition to acid exhaust applications for that reason. Generally, galvanized metal is used for pyrophoric gas cabinet exhaust and because we don't consider these gases acidic by nature, we use an exhaust system that is isolated from our acid/base exhaust.

Pyrophoric and corrosive gases are commonly exhausted from the same tools. The coatings are for corrosion resistance. Epoxy coating (common product names - plasite or tnemec) on galvanized duct work or teflon coating on SS ductwork are common. The teflon coated SS is expensive and not possible to field retrofit. It is beautiful and considered the Cadillac soultion. The epoxy / galvanized solution is more affordable, ducts can be modified in place and epoxy coatings manually painted on any exposed surfaces. If you have a pyrophoric initiated duct fire - the main fuel source of concern is accumulated pump oil - not the corrosion resistant duct coatings. For dedicated Gas Cabinet or VMB Exhaust Duct: coating is not required Bill Flounders UC Berkeley Iulian Codreanu wrote: > Good Afternoon Fab Network. > > Is it a good idea to have the inside of the exhaust ducts serving > pyrophoric gas equipment coated with teflon? > > Thank you very much for your help. > > Iulian From vincent.luciani at nist.gov Tue Jan 31 21:50:16 2012 From: vincent.luciani at nist.gov (Luciani, Vincent) Date: Tue, 31 Jan 2012 21:50:16 -0500 Subject: [labnetwork] duct material for pyrophorics Message-ID: <01F47D4EDEEC64488C10B767D15E48580BD05295AD@MBCLUSTER.xchange.nist.gov> Hello Lulian, We used unlined stainless steel ductwork. Teflon coated is not required but, as Bill noted, is a nice feature. Our nitride LPCVD, which uses dichlorosilane, produces acidic and pyrophoric by products and we see no sign of corrosion so far. We also employ dry pumps for these processes to avoid the oily acidic buildup in the ducts. Good luck on your transition into your new facility...always exciting, but lots of work.
