Evidently you misunderstood what was said in that link, it plainly says that Black Beauty has 1% or less of free silica. As I said no media is "Safe" but Black Beauty is one of the safer ones and has little to no free silica.

I think Cranky posted the text from the link on Black Beauty.

From the link you provided

[The typical free-silica content is stated to be less than 0.1% (Reed Minerals, 1992).]
