When Silica particles are inhaled, it results in the formation of scar tissue in the lungs preventing oxygen from getting in the blood. This condition eventually results in a disease called Silicosis, an incurable and progressive lung disease. Approximately 300 people die from the disease every year in the United States.
More than one million workers are occupationally exposed to crystalline silica dusts in the United States. According to the World Health Organization, more than 100,000 of these workers are sandblasters. What is alarming is that 59,000 of them will eventually develop silicosis.
