You'd think that the liability from this alone would cause changes. I hope so, because 134a is what they are using in the new CFC-free asthma inhalers now (that insurance won't cover). My friend also told me that all eight techs who converted the first Arkansas plant to 134a from R-12 got cancer within a year and a half or so. But I haven't heard of any other such cases, so it could have been caused by something else. I sure hope so. Dan |
