Re: Ambroid PROWELD Label Message #1 Posted by David Smith on 10 Apr 2003, 6:24 p.m. Nope, carbon tet and TCE are two different things. I think one can prove ANYTHING causes cancer. There was a study done where they stuck some mice with a needle. Others were actually injected with distilled water. Guess what? Those injected with water got more cancers than those just stuck. Now why do bottles of water sold in California not say "This produce contains a substance known to cause cancer"? Bags of sandbox sand have the Warning of Doom.

Re: hazardous materials Message #2 Posted by Ellis Easley on 12 Apr 2003, 11:01 a.m., in response to message #1 by David Smith Then there are the things that, if they are as bad as they say now, we might as well just lie down and die. My dad's Electrical Engineer's Handbook, ca. 1940, has a chart comparing insulating oils for capacitors and transformers. PCBs were at least an order of magnitude better than anything else they had, so it's no wonder they were put to wide use. Now PCBs are considered to be extremely hazardous. A few years ago, a power company truck carried a leaky transformer for a few miles through the center of our downtown area. It leaked about 5 gallons of oil that contained a trace of PCBs, the transformer having been drained and refilled with something non-hazardous. All the pavement that had come in contact with the oil was dug up and replaced. Now, maybe PCBs are that dangerous. But for many years, used PCB transformer oil was sprayed on rural dirt roads to keep down the dust!
