Silica Synopsis



  • Chemical Formula SiO₂
  • Silica is Quartz, and is found naturally in almost all rock, sand, soil, brick and concrete products
  • Respirable crystalline silica particles penetrate deep into the lungs causing lung disease
  • OSHA, after decades of scientific studies on respirable crystalline silica, adopted its first PEL in 1971
  • Silica exposure remains a serious threat to nearly 2 million U.S. workers, including more than 100,000 workers in high risk jobs such as abrasive blasting, foundry work, stonecutting, rock drilling, quarry work and tunneling
