Thanks, you’ve done more for me in a day than Airgas has in months.

Thanks for the part numbers. Are those Matheson part numbers?

Hi Deon,

If you order 10 pound bottles and the gas cabinet has scales, when you get to 5 pounds remaining on a source, trigger another order of a 10 lb bottle so there is never more than 15 lb on site but you can have a spare on hand for immediate change outs as needed.

Part numbers are:

G2672843DP;Arsine ULTIMA GX PDISS632SS 10lb

G2675709DP; Phosphine ULTIMA GX PDISS632SS 10lb

Cheers,

Steve

This conversation is for facilities within the US using PH3 and AsH3.

With CFATS lapsing what volume of PH3 AsH3 is your facilities ordering? Our Division of Research and Safety, understandably, would like to abide by the volume limitations just in the event CFRATS is resurrected. I am of the understanding that CFATS is on the back burner for a while if not indefinitely. CFATS volumes seem to create an obstacle that our local gas distributor does not want to help us manage. With CFATS and our H-5 Semiconductor certification we are only allowed to have limited quantities listed in the tables below. Our local municipalities have no f regulations limiting these materials other that the state and Federal regulations.

What volumes of Phosphine and Arsine is your facility ordering? What vendor are you using and what are the part numbers? DRS would prefer 15# of product to minimize cylinder change out and still fall under the CFATS regulations.

We have been asking Airgas and Matheson for a part number for months. Neither have provided a part number for us to order PH3. We are using 100% AsH3 and PH3 in our process.
