<p class="MsoNormal"><span style="color:#1F497D">Here at Draper we have one exhaust stream for Solvents and one for Corrosive. Silane ends up on the corrosive side. I do not think that you want to mix gases that combust with air in a duct with solvents. Sounds
like an accident waiting to happen.<o:p></o:p></span></p>
<p class="MsoNormal"><span style="color:#1F497D"><o:p> </o:p></span></p>
<p class="MsoNormal"><span style="color:#1F497D">Is your duct work plastic or metal? If it is metal I would not be surprised if you have lots of corrosion in a common system. I would be very careful and at least consult the Universities Insurance carrier for
an opinion and read up on the NFPA and building codes for your area.<o:p></o:p></span></p>

<p class="MsoNormal">Hello,<o:p></o:p></p>
<p class="MsoNormal"> Here in my lab we have a PECVD system that uses 2%silane in argon. The cylinder is in a cabinet in the service chase. The silane shares this cabinet with a bottle of ammonia. The cabinet is connected to the general exhaust
that is used throughout the lab. I don’t really like the setup but this is how the system was running when I was hired and came to the university. This setup is different from my industrial experience where the silane was outdoors in a bunker.
<o:p></o:p></p>
<p class="MsoNormal"><o:p> </o:p></p>
<p class="MsoNormal">The lab will be moving to a larger cleanroom space. While I will not have an outdoor bunker at the new facility, I will take this opportunity to improve the situation. I intend to purchase a new cabinet for the 2%silane that will allow
me to use a cylinder with a pneumatic valve, DISS fitting and a dedicated purge cylinder. This is more in line with my prior experience. Are there any concerns or issues with connecting the cabinet to the common exhaust? Again this new lab only has general
exhaust that runs throughout the entire lab. <o:p></o:p></p>
