Margaret Looks like this is all they have. I spoke with Barry Ly ons of BOC this morning. He said there is a woman, Jane Gartshore, of Cool Concerns who gives the class on hy drocarbon refrigerant. CARE sends their technicians to her for training on hy drocarbon refri gerants. Ispoke to her and she told me she follows the attached guideline and uses slides about the Cool refrigerants and hands out the ACRIB_HC_Guide which is covered in the class. Steve Hammerling of ASHRAE said they do not have an ything in place for Hy drocarbon Refrigerant since it is not legal in the U.S. O nce legal, they will put guidelines in place.
