Dear Margaret:
 
Got this from Mr. Emad Jafa. He is waiting for me to get an answer from 
the EPA,
on my refrigerant. He forwarded this email address on the standards and 
regulations in the UK.

Richard,
hydrocarbon refrigerants (HC) are approved and safe in Europe.  In 
domestic refrigeration, HC has been used for many years. As far as R290, 
it is being used in freezer and commercial refrigeration system.  As far 
as R600a it is being used in domestic refrigeration for many years now.  
R134a is not allowed to be used in domestic refrigeration.  However, R600a 
is allowed in domestic refrigeration in small appliances and if the charge 
is less than 150g.  R600a still not allowed in large refrigerator or 
commercial refrigeration because of it's flammability issue.  EU might 
increase the limit of charge to be more than 150g, but no one knows when.
I do not have safety standard procedure to pass to you but you can get 
some information on the web.
I hope that helps
Emad

Dear Emad:
 
Do you have anything on this that I can pass on to the EPA.
 
Thank you

Richard,
I'm sorry to hear you didn't get a response concerning the European 
experience with hydrocarbon refrigerators.  That information could be very 
relevant to clearance in the US and relevant to implementation.  By having 
a standard or a program of safety procedures already prepared, you could 
make it much easier for interested manufacturers to use HCR-188C if it is 
approve.  This also would be evidence that safety issues have been well 
considered.

I have no information European standards because my main concern is the 
U.S. clearance. I did inquire but never got a response.

Richard, 
Thanks for following up.  I expect to be writing to you on the status of 
your application for MVAC after consultation with my supervisor. 
 
I will want to go back over the checklist attached to the incompleteness 
letter for white goods to see what further information we want.  Have you 
found any information about European standards, guidelines, or experience 
for using hydrocarbons in appliances?

Dear Margaret and Karen 

Got this proposal from ARA Engineering on the CFD Modeling. 
If it meets your approval then I will have them proceed with it. 
If you have any questions please feel free to contact me. 

Richard 
Richard, 

Attached is our proposal to model the refrigerant leak. 

I apologize to for the delay, we fell behind last week. 

Please call Roxanne if you have any questions
