First of all, Dryburgh, at least, is no longer selling the odorless, as, according to him, it didn't work as well. Second, the Odorless was just as irritating to those susceptible, however its molecular weight was heavier, so it tended to sink to the floor, rather than waft around. Third, fans don't work, unless you have both a pull and push fan, but even then, if you are not venting the fumes, you will just recirculate them, and they will get you. A single fan just creates turbulence around the work area, but does not remove the fumes. That includes the ODORLESS. John Page (belatedly responding to Mike Magness's memory) was the one who suggested the vacuum with TWO hoses, the second exhausting out the window. That is the ONLY way I will do these projects in the future, as I have had TWO respiratory episodes (not the skin), the second one after using a cartridge respirator and fan. I have a beard, which compromises any partial face mask, but I was hoping. I think that any future discussion of CA techniques on this list should include a warning/reminder. Some of you may, in fact, be immune to its effects, or at least think you are, until your bodies say "enough". After that, even the thought of CA will generate a reaction! sort of. I admit, the warning on a cigarette package does little to deter anyone who wants to smoke, but it keeps the Surgeon General busy...you know - signing all those packs. Hope you're feeling better Grebe.
