Silica dust is a hazardous substance that can cause silicosis, lung cancer, and other lung diseases. It is commonly found in rocks and can become airborne through processes such as grinding or cutting. Workers in industries such as sandblasting and ceramics are at risk. Safety precautions such as filtration systems and education can help limit exposure.
Silica dust is a potentially hazardous substance to which some workers may be regularly exposed. Dust can be released through virtually any process that destroys rocks or sends dust into the air. One of the most serious dangers of silica dust is silicosis, a condition that can reduce a person’s breathing capacity. Exposure to dust can also lead to lung cancer, stomach cancer and kidney disease. It can also lead to other lung diseases, such as tuberculosis and emphysema.
Silica is commonly and abundantly found in much of Earth’s rock and can become airborne when that rock is destroyed. If there is destruction or pulverization of the rock, such as grinding or cutting, which results in dust, the danger of silica inhalation may be present. Many workers can be exposed to silica. One of the best-known industries at risk from silica inhalation is sandblasting. Another sector at risk is that of ceramics or glass.
Exposure to silica dust can cause symptoms such as coughing and difficulty breathing. Exposure to silica can also increase a person’s risk for various lung diseases. Tuberculosis, fibrosis, and lung cancer can all develop after a person is exposed to airborne silica. In addition, kidney disease or kidney disease, stomach cancer, and kidney inflammation may develop. It is important, therefore, for a person to limit their exposure to airborne silica as much as possible, especially if they work in an industry where they may be exposed to it.
Inhaling silica dust can lead to a serious disease known as silicosis. Silicosis occurs when airborne silica is inhaled and enters the lungs. Dust particles irritate the lungs and cause inflammation. Eventually, the body’s immune system will cover the area with scar tissue. Scar tissue can disrupt the lungs’ ability to absorb oxygen and thus can disrupt a person’s ability to breathe.
Silicosis can come in three different forms. Acute silicosis can develop if silica dust is inhaled in large doses over a short period of time, from a few weeks to five years. Accelerated silicosis can take five to 10 years to develop. Most cases of silicosis are chronic silicosis. This form of the disease often occurs when a person inhales silica over a period of 10 to 40 years.
There are some safety precautions a person can take to limit their exposure to silica dust. For example, a breathing system with filtration may be used. Another system uses water to keep dust from becoming airborne. A person may also wear special clothing or use an appropriate ventilation system to prevent the dust from being inhaled. A workplace can also educate its workers about the danger of silica dust and how best to avoid it.
