Re: Media Question
this is purely hearsay and as best i remember:
someone on another forum mentioned that coal slag is as bad or worse than sand, because it contains a lot of arsenic. they may have said it still has silica dust, too. and they claimed it will probably be banned in the next few years. ...not sure if any of that is right. i'm guessing the banned part was speculation unless osha's on it.
