In a move the EPA deemed ‘historic,’ the agency has banned chrysotile asbestos, the only form of the cancer-causing mineral that the U.S. still imports and uses

      There are certain places where even with it’s problematic nature, it was the more desirable material. Normally in industrial applications where temperatures would be several hundred degrees for long periods of time. Most of the replacements aren’t much better in regards to the long term health risks they pose.

        I quit working in a factory setting a couple years ago. It was definitely unsettling seeing dozens of pipes running all through the facility, and a few are labeled “Asbestos-Free”.

        I would think most of those applications should be able to use an alumino-silicate based refractory ceramic fiber. Kaowool is one brand, but there are many like it.

        It has its own problems in regard to silicosis but that’s only after it’s been exposed to higher temperatures and are easily mitigated with most particulate respirators. Also, if I remember correctly, the silicosis threat requires very long term exposure. I do know of at least one company developing a silca-free version too, which would eliminate the silicosis threat.

        I use it in glass manufacturing with temperatures 2000°F+ so I’m quite confident it’ll hold up to any application where asbestos is being used.

        EDIT: It will hold up in any application unless there’s a problem with certain chemical reactivity I should say*. I don’t expect that would be a common problem, but I’m sure it could happen. I’m admittedly not well versed on asbestos since I’ve never tried speccing it out for anything, haha.

          Dust from refractory isn’t good to breathe. Koawool still has warnings not to inhale the fluff. Anything that has silicate in it is a respiratory hazard when it has particles small enough to get into your lungs. And it, like asbestos, will cause issues. The speed at which these issues show up is linked to the amount you are exposed to. If you breathe clouds of the stuff for weeks on end, it’ll show up a hell of a lot quicker than if you are exposed irregularly over years. ANY TIME you are working a SILICATE based material, you should be wearing respiratory protection (or around any dust really, even you are cleaning air vents or sanding wood). Silicosis is a killer, dust doesn’t belong in lungs.

          Oh yeah? How is it for making Chlorine…because that’s one of the big uses for chrysotile asbestos (the kind that was just banned.)

        Nah, his rule there didn’t really do much. Asbestos was already 98% banned long before he took office and his stupidity didn’t move the needle on it’s use.

        In reality the type of asbestos in the article still has an exemption in Canada and other countries because of its specialty uses like creating the Chlorine used for water treatment. Yes we needed to be done with the stuff but Trump really had nothing to do with why we were still using one specific type of it for a short list of specific needs.
