Silicosis is the most common disease from excessive exposure to silica dust. Silicosis is a scarring, fibrotic lung disease that affects a person's ability to breathe. Several hundred people in the U.S. die from silicosis every year. There is no cure for silicosis, but it is preventable. Because you cannot see dust does not mean it is not present.
Dust particles that affect the lungs are so small that they are invisible to the naked eye.
Some dust particles are so light that they float in the air and take long periods to settle to the ground. You can help in the efforts to elim-inate silicosis from the workplace by being aware of silica hazards, and following safe and healthy work practices. You have a lot of control over how much silica dust you may be exposed to. Follow all company policies and procedures regarding dust control. Try to use all possible steps to protect yourself.
