Crystalline Silica• Crystalline Silica (respirable) has been identified by the International Agency for

Research on Cancer (IARC) as a “Group 1” carcinogen. OSHA therefore requires all products containing more than 0.1% crystalline silica to be labeled as a cancer hazard.

• Crystalline Silica is the principal cause of the silicosis and related lung diseases and is responsible for approximately 300 deaths in the US each year.

• Respirable Crystalline Silica is federally regulated by the EPA, FDA, & OSHA. NIOSH also considers crystalline silica to be a carcinogen.
