Hypersensitivity due to changes in how the body's immune system reacts is poorly understood at present and is a matter of conjecture in the medical profession. An arthritic condition can appear when the body mistakes tissue in its own joints as a foreign substance so stiffness as an initial symptom is reasonable. Apparently just about any chemical is capable of triggering the enhanced response. There was a lot in the press a few years ago but the number of articles seems to have fallen off.

Apparently this is caused by dermal exposure to the compounds in the B&W fixer, which I assume it to mean thiosulphate. The initial symptoms are tightness in the joints of the hands. Does anyone know any details of this phenomenon? It is supposed to be reasonably well documented but not widely known. I understand that the sensitivity is quite severe. - Andrew. > > I have taken to wearing sweat pants and a sweat shirt. Actually, this has become my routine around-the-house costume. I use paper towels and toss them after one use. That absolutely prevents contamination. My lady friend does not understand why I go through so many paper towells. I use tongs these days. I hate rubber gloves but don't put my hands in the chemicals any more. I do have a good plastic apron made by Kodak but don't much use it. If I were working with anything hazardous I would take considerably more precautions. --- Richard Knoppow Los Angeles, CA, USA dickburk@xxxxxxxxxxxxx ======================================================================== ===================================== To unsubscribe from this list, go to www.freelists.org and logon to your account (the same e-mail address and password you set-up when you subscribed,) and unsubscribe from there. ====================================To unsubscribe from this list, go to www.freelists.org and logon to your account (the same e-mail address and password you set-up when you subscribed,) and unsubscribe from there. ============================================================================================================To unsubscribe from this list, go to www.freelists.org and logon to your account (the same e-mail address and password you set-up when you subscribed,) and unsubscribe from there.
