Locations of natural gas lines

July 6: PDFs showing location of existing natural gas service piping in labs 201, 205, 288 & 292 sent to Ken Filice to be forwarded to G. Wilson Inc.

Copy of July 5 email to Ken Filice regarding gas service to Labs 292 & 288:

Ken,

I've attached PDFs of four BME labs 201, 205, 288 and 292 for Kenny of George Wilson. They show the locations of the various gas services.

CO2 SERVICE:

To confirm our discussion in Rm 288, we would like a pressure gauge on the CO2 line where it enters Rm 288.

We need pressure regulators at the points of termination. The CONCOA 405 series single stage brass line regulator was recommended by Praxair, but an equal substitution is OK. (www.concoa.com)

We want to terminate at the incubators with a Swagelok quarter turn valve with a compression fitting. The thread should be mated to a hose fitting, and vinyl tubing will be the last leg.

According to the Praxair technical representative, if the copper line feeding the room is 1/2", it will need to be stepped down to 1/4" piping at the termination points.

At the Biosafety Cabinets you will be connecting the CO2 line to the plugged penetration on the right hand side of the cabinet as we pointed out this morning. The interior connection should receive a petcock with hose fitting. The exterior connection is CGA 320 (you should confirm).

Let me know if George Wilson wants contact information for the Praxair technical specialist.

RMS 201 AND 205

When we toured Rms 201 and 205 this morning I should have said that Rm 205 would get gas to the island benches and 201 would get gas next to the fume hood rather than the other way around. The drawings show the correct locations for natural gas service in Rams 201 and 205.
