<p>Hi Valery,</p>
<p>We are developing a document to help with the OSP. Patrizia is
looking into the pressure systems calculation and assignment of a
DA, she will provide guidance and we will assist as directed. We
will make you know what needs to be done as soon as we complete
the documentation and receive guidance from Patrizia.</p>
<p>Thanks,</p>

Tyler Lemon is the DSG point of contact for the RICH
interlocks, he can assist you with any info on the
interlock information. That is with the exception of
the RICH gas controls interface chassis. <br>
<br>
This is a chassis which is being assembled by the
DSG, it contains two power supplies (24VDC and +/-
15V) which are used to provide power for the mass flow
transducers, humidity and temperature sensors. It also
provides an interconnect for the sensors and
transducers to the RICH Interlocks cRIO. The chassis
has circuit protection fuses, is grounded, and the
power supplies are completely enclosed to eliminate
any electrical shock hazards.<br>

Although the nitrogen in the system is a relatively
small amount, Bob Miller would have to provide the
answer this question...as all Hall Gas systems have to
be considered in an ODH calculation.<br>

DSG will be providing software to control turning the
compressors on and off remotely, additionally there
will be a local method. Once defined, DSG will provide
documentation and training to the Hall B staff
responsible for daily operation of the detector and
any after hours on-call support. Once on, the gas
operation will not be controlled by any
instrumentation such as a mass flow controller, the
system is set up to always flow gas/air as long as
everything is in working order.<br>

Again, Saptarshi provided the documentation on the
relief valves and any other ASME pressure numbers.
The piping and valve equipment is all standard, we do
not perceive any necessary adjustments to valves once
they are set. The tank is above the 15PSI limit and is
considered a pressure system, but there are engineer
specified relief valves in the design and there are no
welds. Saptarshi can probably give you more specifics,
if you need them.<br>
