Hey Pony, How many cigarettes do you smoke???
TnTjigman wouldnt it only be fair to say that you are working in a more controlled environment when it comes to this stuff compared to the average jig pouring man doing it out of his garage or basement. What I mean by that is there exhaust ventilation systems and such should be more capable of doing what they are designed to do, than the make shift window fan put in a doorway to help create air circulation.
I guess what it comes down to would be the individuals choice on whether or not to just take some added precautions and use a respirator or not. Like everything else you do in life there are good sides and bad sides it all depends I guess on who is doing the talking, but in the end it is the individuals choice, at least for the time being anyway.
