ive been waterproofing basements for 13 years. we jackhammer concret all day and the basements get very dusty. masks are worn but their not 100%
I've only tried it once. I prefer cocaine.
its bad, you should be using a face mask, it can cause a disease called silicoses, and it works on your lungs over time like cement hardens. look it up.
i like tiny's answer... though, i don't do that stuff... concrete is very bad for you. not QUITE as bad as asbestos, but damned close to it. you can get emphysema, lung cancer, CONCRETE OPHTHALMIA etc etc from prolonged exposure, just like you can get concrete poisoning from laying wet concrete and not washing it off of you. i'd find a new line of work and do something to clean out your lungs.. i hope you aren't a smoker on top of that. as far as masks go, that obviously helps, but it depends on the quality of the mask obviously. I would assume you know the difference -most likely better than i would.
as you know, when cement dust mixes with water it turns into cement when dried...now your lungs have moisture in them and when you breath that stuff in it mixes with the moisture in your lungs. so when you breath it in it can turn into cement in your lungs...so its not good at all. make sure your mask is on properly and never work with cement without a mask on. =]
