1 and this is to you and others from Lin Pac. It says: "We
2 have now carried out our initial trials on our stocks and
3 production". Then there are some numbered paragraphs and
4 he says at the last paragraph, this is Mr. O'Shea: "I am
5 sorry for the problems Pentane foam is causing you all.
6 I can only say, and it is perhaps no consolation, we are
7 finding the change-over from CFCs back to Pentane no
8 holiday either". Were Lin Pac Plastics a little unhappy at
9 this stage, Mr. Oakley, as it would suggest?
10 A. They were struggling with the change.
11
12 Q. When was the change actually effectively completed, can you
13 remember? Give a month, not an actual date?
14 A. The whole market was put on to packaging blown with
15 Isopentane in July 1988.
16
17 Q. July 1988?
18 A. Yes, so these letters you are referring to here are
19 after the entire market had changed.
20
21 Q. That is the entire market in this country?
22 A. Yes.
23
24 Q. And Ireland?
25 A. Yes.
26
27 Q. So far as you have described some of the problems with
28 hydrocarbons, one of which is that they are flammable ---
29 A. Yes.
30
31 Q. -- as we used to say inflammable and, therefore, perhaps
32 somewhat dangerous, are you conscious of any environmental
33 detriments involved in the use of hydrocarbons for blowing
34 polystyrene foam?
35 A. I think there are. I cannot be specific. Certainly,
36 the impact on the ozone layer in using a hydrocarbon is
37 dramatically less than it is using a CFC blown package. I
38 do not think it is the ultimate ideal world, but it is a
39 major step forward from CFCs. The next phase is yet to
40 come, as I alluded to earlier.
41
42 Q. The chronology you have given us tells us that CFCs began
43 in 1986 in this country?
44 A. Yes.
45
46 Q. But had disappeared from use at any rate from McDonald's
47 products by July 1988?
48 A. That is correct.
49
50 Q. Did HCFCs and, in particular, HCFC-22 ever come into the
51 picture so far as McDonald's in this country is concerned?
52 A. McDonald's in the UK have never used packaging blown
53 with HCFC-22.
54
55 Q. At this day -- I may have asked you this already so
56 I apologise -- is it still Isopentane that is being used
57 for polystyrene foam?
58 A. Yes, it is.
59
60 Q. I want to, if I may, ask you some questions generally about
