Breathing silica dust is bad. I'm so glad that there are government agencies with the autonomy to make rules about this kind of thing -- oh... oh oh no.
(This particular rule is under attack from multiple sides. I wonder how much money it's worth to the mine owners? How much do they get for each year of hacking and suffering in old age from their workforce? We should count it up. Write it on a cake. Make them a cake. Give them the cake. )
