    It’s been banned in new construction for a long time I believe. What they recently banned was the niche use of it in industrial applications I believe. Which pretty much completely banned it

      It’s one of those materials that has an almost complete list of superb properties, with one overwhelming downside. It’s cheap, abundantly available, completely fireproof and can be woven into fireproof cloth, adds enormous structural strength to concrete in small quantities, very resistant to a wide range of chemical attacks. It’s just that the dust causes horrific cancers. See also CFCs, leaded petrol, etc, which have the same ‘very cheap, superb in their intended use, but the negative outweighs all positives’.

      One of the ‘niche industrial applications’ was the production of pump gaskets in high-temperature scenarios, especially when pumping corrosive liquids. We’ve a range of superalloys that are ‘suitable’ for these applications - something like inconel is an absolute bastard to form into shapes, but once you’ve done so it lasts a long time. But you still need something with similar properties when screwing the bits together. For a long time, there was no suitable synthetic replacement for asbestos in that kind of usage.

      If you know that the asbestos is there, have suitable PPE and procedures, then IMHO it’s far from the worst industrial material to work with. It’s pretty inert, doesn’t catch fire or explode, and isn’t one of the many exciting chemicals where a single droplet on your skin would be sufficient to kill you. What is inappropriate is using it as a general-purpose building material, which is how it was used for so long, and where it was able to cause so much suffering for so many people.

        The biggest problem with it is that the particles are so small that they can stay afloat for weeks without any airflow. They are just that light.

      Allegedly, if there’s asbestos in your workplace, it’s better to leave it and not remove it. IE, in wall or ceiling paint
