Not sure where you got your info but Black Beauty is no where near as bad as regular sand, actually Black Beauty is one of the safer alternatives to silica sand and contains very little silica (usually less than 1%) or none at all. No blast media is completely safe but some, such as Black Beauty, are much safer than sand.
