Silicosis is permanent lung damage caused by breath- ing dust containing extremely fine particles of crys- talline silica. Crystalline silica is found in materials such as concrete, masonry and rock.
Is concrete dust bad?
Concrete dust can be very harmful. Even the slightest amount of exposure can cause irritation to the eyes, nose, and throat. Prolonged exposure can lead to lung cancer and other respiratory problems. It is for these reasons that it is essential to protect saw machine operators from this harmful situation.
Can you get silicosis one time exposure?
Acute silicosis – caused by short-term exposure to very large amounts of silica – is rare. In these cases, the cough and shortness of breath can appear within days or weeks of exposure to silica, with weight loss, tiredness and wheezing developing within a few months or years.
How quickly can you get silicosis?
Silicosis usually develops after being exposed to silica for 10-20 years, although it can sometimes develop after 5-10 years of exposure. Occasionally, it can occur after only a few months of very heavy exposure.
How likely is it to get silicosis?
A recent study of pottery workers found high rates of silicosis, up to 20%, among workers with an average exposure of 0.2 mg/m3 over many years.
Can breathing concrete dust hurt you?
Most concrete and masonry products contain large amounts of sand. When you inhale the dust, silica particles scar your lungs, causing a disabling, irreversible, and incurable lung disease called silicosis. … 34:5-182) prohibits dry cutting and dry grinding of masonry materials.
Is concrete toxic to humans?

Is concrete toxic?
Concrete causes damage to the most fertile layer of the earth, the topsoil. … The presence of some substances in concrete, including useful and unwanted additives, can cause health concerns due to toxicity and (usually naturally occurring) radioactivity.
What happens if you breathe in silica?
Breathing crystalline silica dust can cause silicosis, which in severe cases can be disabling, or even fatal. When silica dust enters the lungs, it causes the formation of scar tissue, which makes it difficult for the lungs to take in oxygen. There is no cure for silicosis.
What is Acute silicosis?
Acute silicosis results from short-term exposure (weeks or months) of large amounts of silica. The lungs become very inflamed and can fill with fluid, causing severe shortness of breath and low blood oxygen levels. A cough, weight loss, and fatigue may also be present.
Does all concrete have silica?
What construction materials contain silica? Many common construction materials contain silica including, for example, asphalt, brick, cement, concrete, drywall, grout, mortar, stone, sand, and tile.

Water not only helps cool and lubricate the blade but also keeps the dust down. These cut the fastest and cleanest, but they require a special saw that can both distribute water and be safely used around it.
What is concrete poisoning?
There are three factors in concrete poisoning: the abrasiveness of concrete mixtures, the alkaline (high pH) nature of cement, and the chemical and metal content. Cement, which you find in products like concrete, mortar, and grout, is extremely caustic or corrosive.
What is in concrete toxic?
The cement causes many issues: it is highly toxic, prompting eye, skin and respiratory tract irritation, and contains calcium oxide, corrosive to human tissue, and chromium, which can prompt severe allergic reactions. Then there’s silica.

How long does concrete dust stay in the air?
Because of its small particle size, it can stay in the air for up to 12 days. Sometimes, when we don’t see dust, we might still smell it e.g. if a room smells “like concrete” cement can be circulating in the air.
Do lungs clean themselves of dust?
Luckily, the lungs have another function – they have defense mechanisms that protects them by removing dust particles from the respiratory system. For example, during a lifetime, a coal miner may inhale 1,000 g of dust into his lungs.
Is house dust harmful?
Dust allergies can cause wheezing, asthma attacks, bronchial infections, dermatitis and other allergy-related problems. Dust also contains chemical particles, including pesticides and other dangerous substances found in and around your home. Exposure to these may cause long-term health problems.
Who is most at risk of silicosis?
Who is at risk for silicosis? Factory, mine, and masonry workers are at the greatest risk for silicosis because they deal with silica in their work. People who work in the following industries are at greatest risk: asphalt manufacturing.
Can concrete dust cause sore throat?
Depending on the level of exposure, effects may range from redness to chemical burns and blindness. Inhaling high levels of dust may occur when workers empty bags of cement. In the short term, such exposure irritates the nose and throat and causes choking and difficult breathing.
