Dust blows off a pile of fracking sand at a mine near Chippewa Falls, Wis., on Dec. 15, 2011. Some of the air samples the National Institute for Occupational Safety and Health experts collected at fracking sites had such high levels of silica that the respirators typically worn by workers wouldn’t offer enough protection, according to NIOSH standards.

    Are you afraid to use your real name and take responsibility for your comments?
    As to get a clue about the process, perhaps you should read a few of the many posts on this site and learn about the difference between “Farm Dust” and freshly broken silica sand.
    You can call our local expert Dr. Crispin Pearse in Eau Claire if you really care to get educated….The breathe deeply!

    Get a clue about the process before you start spouting off things at random….silica dust is everywhere! Ever see a farmer turn over a field?

Courteous, concise comments relevant to the topic are welcome, whether or not they agree with the views that predominate here. Long rants proclaiming the infallibility of your own views or favorite ideology will not be posted, neither will repeated attempts to hammer on a point already addressed, nor will comments containing profanity, abusive language, flame-baiting and name calling. Please indicate precisely what you are blogging about. I just got a post from ? E-Mail ? which said: "Is this going to be OUR furture??. I have no idea what they were referring to and no way to contact them. This is why we prefer comments that are signed by actual persons who leave their E-Mail address (it won't be published) so they can be contacted if questions arise.
