USING MOSTLY IN GULF COUNTRIES BCOZ THEY HAVE MORE SAND OF BLASTING FREE OF
COST OF COURSE IT IS FREE . COPPER SLAG TOO BANNED BUT STILL IN INDIA AND OTHER
COUNTRIES STILL USING. BEST SAFE IS GARNET BLAST. IT IS SAFE YES TILL ANY
ALTERNATE BLASTING MATERIALS COMES.

Silica means the sand,.due to blasting,size of thesand would become very minute

So internationaly sand blasting has been banned...
However copper slag can be used for abrasive blasting..
