TheIt's also an inhalation hazard, along the lines of asbestos. Do NOT put it in your tumbler.
I work with Diatomaceous Earth (DE) every day... I'm in the pool business. There are 2 kinds of DE... pool filter DE, which also has silica in it, and natural DE... with no silica. If you want to run DE, get the natural kind... which actually is good for pest control, and some people ingest, believe it or not, for various reasons. Natural DE is not poisonous, per se, but does pose an inhalation hazard.
