What is crystalline silica?
What is crystalline silica? An abundant natural material, crystalline silica is found in stone, soil, and sand. It is also found in concrete, brick, mortar, and other construction materials. Quartz dust is respirable crystalline silica, which means it can be taken in by breathing.
Is crystalline silica the same as silica?
Silica is commonly found in nature as sand. Silica exists in many different forms that can be crystalline as well as non-crystalline (amorphous). Crystalline silica is hard, chemically inert and has a high melting point. These are valued/important properties in various industrial uses.
Why is crystalline silica bad for you?
Breathing in very small (“respirable”) crystalline silica particles, causes multiple diseases, including silicosis, an incurable lung disease that leads to disability and death. Respirable crystalline silica also causes lung cancer, chronic obstructive pulmonary disease (COPD), and kidney disease.
What is crystalline silica OSHA?
Crystalline silica is a common mineral that is found in construction materials such as sand, stone, concrete, brick, and mortar. When workers cut, grind, drill, or crush materials that contain crystalline silica, very small dust particles are created.
Is crystalline silica safe?
What is the danger of crystalline silica exposure? Crystalline silica has been classified as a human lung carcinogen, and can cause serious lung disease and lung cancer. It only takes a very small amount of respirable silica dust to create a health hazard.
Is silica in beach sand?
Silica is one of the most common minerals in the earth’s crust. Glass, beach sand, silicone, and granite are all silica materials. The most common form of crystalline silica is quartz, which is found in sand, gravel, clay, granite, diatomaceous earth, and many other forms of rock.
Is silica harmful to humans?
Inhaling crystalline silica can lead to serious, sometimes fatal illnesses including silicosis, lung cancer, tuberculosis (in those with silicosis), and chronic obstructive pulmonary disease (COPD). In addition, silica exposure has been linked to other illnesses including renal disease and other cancers.
Does all sand contain crystalline silica?
Yes, most of our sands (and most sands sold in home improvement and big box stores) have crystalline silica in them because they contain quartz sand grains (which is the common name for crystalline silica). These are the same quartz grains found on 99.9% of the ocean, lakes and stream beaches in the US.
Is silica dust in drywall?
1. What exactly is silica dust? Crystalline silica is found in brick, concrete, mortar, drywall, and other construction materials, as well as in asphalt, glass, topsoil, and more. Particles of crystalline silica that are small enough to be respirable (i.e., taken in by breathing) is called silica dust.
What happens if you breathe silica dust?
Breathing in these very small (respirable) crystalline silica particles can cause irreversible scarring in the lungs, trouble breathing, permanent disability, and death. Crystalline silica dust can also cause lung cancer, kidney damage, and autoimmune disease.
What is silica used for in construction?
Construction Materials Silica sand (often called industrial sand when used for this purpose) is the main structural component in a number of construction products. Flooring, mortars, cement, roofing shingles, asphalt, and other industrial materials all use silica to improve durability and structural integrity.
How does crystalline silica cause cancer?
Exposure of workers to respirable crystalline silica is associated with elevated rates of lung cancer. The strongest link between human lung cancer and exposure to respirable crystalline silica has been seen in studies of quarry and granite workers and workers involved in ceramic, pottery, refractory brick, and certain earth industries.
Is crystalline silica the next asbestos?
Crystalline Silica – The New Asbestos . Respirable crystalline silica (RCS) has been touted as “the new asbestos” due to a recent surge of silicosis diagnoses, one of the most common occupational lung diseases affecting workers worldwide. It is believed that this significant workplace hazard could rival the impact of asbestos in coming years as the full extent of the problem is still coming to light.
Why is silica bad for You?
Long answer. Silica also acts as a diuretic, which can be dangerous for anyone taking a “water pill.” Taking both together can lead to dehydration from the excessive water loss in the body, which can also cause electrolyte imbalance. Potassium is typically the most affected by this situation, as levels become very low.
What are the dangers of silica?
Prolonged exposure to crystalline silica may cause toxicity. Lung damage and chronic obstructive pulmonary disease are common side effects. However, crystalline silica has a different chemical makeup than dietary silica, so the dietary form doesn’t carry these risks.
