It contains <strong>less than 1% free crystalline silica<\/strong>, is chemically inert and non-toxic, and produces far less respirable dust. That combination is exactly why regulators and contractors increasingly specify it over traditional blast sand. For the full technical profile, see our guide to <a href=\"https:\/\/hlh-js.com\/resource\/blog\/garnet-abrasive-blast-media\/\" target=\"_blank\" rel=\"noopener\">garnet abrasive blast media<\/a>.<\/p>\n    <\/section>\n\n    <section class=\"gsafe__s\" id=\"gsafe-silica\">\n      <div class=\"gsafe__k\">The Core Issue<\/div>\n      <h2>Free Silica &amp; Silicosis<\/h2>\n      <p>Silicosis is an irreversible, incurable lung disease caused by inhaling respirable crystalline silica. Many mined blasting sands contain high levels of free silica, which is why silica sand is banned or tightly restricted for blasting in a growing number of countries.<\/p>\n      <p>Almandine garnet is an iron-aluminium silicate, but the silica within it is chemically bound rather than free &mdash; its free crystalline silica content typically sits below 1%, well under the limits set by occupational health regulations.

Garnet is hard and tough, so it shatters far less on impact than slag or sand.
