It is far, far closer to the truth to say that the foam degrades in all cases than to say that it degrades in some cases."
Again: how can you possibly know this? It's pure speculation on your part, pulled from thin air.
Bobbie, Sam isn't saying that foam degradation 'may' happen. PR says this. Sam is saying that every single machine has been issuing a constant stream of carcinogenic particles since day one of its operation. He's saying this IS happening.
What Qwerty writes is true. Foam has degraded and it's frightening. I've also read on this thread that people have opened their machines and found the foam to be intact.
My point has never been that this can't happen--clearly it does. After all, this is a class 2 recall, which is serious. My point is that we don't know the extent of the problem. People are rightly worried about their machines. Adding a lot of unproven and unlikely nightmare scenarios only brings more stress.
I stand behind my statement. PR makes medical grade machines. These have to meet regulators specifications. the foam has to meet those same specs in order to be installed in the machines. Obviously, something was missed! But Sam claiming that regulators have missed carcinogenic particles being emitted in a constant stream since 1993, worldwide, in machines that aid breathing, seems incredible. Sam's 'proof' struck me as being pretty darn weak--no proof at all. It had nothing to do with pre pur foam in these machines.
"I do not understand why you think proof is needed for saying something MAY happen. " fine. It MAY happen that I'll be struck by lightning or eaten by a bear. Should I assume that it will every time I go out of my house? No.
It would be irresponsible for me to post that there are millions of unreported cases of people falling from Half Dome on a forum for people who have a fear of heights. That's what some here are doing.
