Silicosis Exposure at Work: Which Jobs Are Most at Risk?

Silica dust exposure happens when workers cut, grind or disturb silica-containing materials such as stone, concrete or sand. Workers then inhale tiny crystalline silica particles that are at least 100 times smaller than ordinary grains of sand. This dangerous exposure and inhalation can cause silicosis.

Silicosis is a progressive disease that damages the lungs, making it difficult to breathe. There is no cure, and treatment can only ease symptoms. The disease can get worse over time, and it may lead to a lung transplant or death.

Some jobs, such as processing quartz stone countertops, may put workers at higher risk of silica exposure, increasing the likelihood of developing silicosis or other silica-related lung diseases.

Jobs with the highest silicosis risk are those where workers cut, grind, drill or crush quartz, concrete, rock or engineered stone. About 2.3 million workers are exposed to silica on the job in the United States, according to OSHA.

Occupations Most Affected

The most dangerous sectors include stone fabrication (especially engineered quartz), construction, mining, tunneling, sandblasting and foundry work.

In recent years, many silicosis cases have come from workers who cut, grind, fabricate or polish engineered stone quartz used to make kitchen and bathroom countertops. These workers often develop the disease quickly, and it’s typically a more serious type of silicosis.

California has become a hotspot for silicosis cases among engineered stone workers because the state tracks diagnoses and makes silicosis a reportable disease. As of August 13, 2026, there have been 631 confirmed countertop-worker silicosis cases and 32 deaths in California, according to the state’s Engineered Stone (ES) Silicosis Dashboard.

Tasks and Work That Create Silica Dust Exposure

On-the-job tasks that may create silica dust exposure include processing or otherwise disturbing silica-containing materials. Workers in the countertop manufacturing, finishing and installation industries who work with hand-held power tools that saw, grind and polish quartz slabs have some of the highest instances of silica dust exposure.

Workers who open bags of silica powder, move or mix raw materials, clean dust collectors or scrape mixers may also be exposed to silica dust. In addition to silica exposure, people who work in the construction and mining industries also have an increased risk of asbestos exposure. Asbestos can cause mesothelioma, an aggressive cancer that most commonly affects the lining of the lungs.

Yes. In rare situations, a single very high‑intensity exposure to silica dust can trigger acute silicosis and serious silicosis symptoms, but most people who develop silicosis have been exposed repeatedly over months or years.

Acute silicosis is the form closely linked to short‑term extreme exposure. This can happen when someone breathes large amounts of respirable silica dust in a confined or poorly ventilated space, such as sandblasting or cutting stone indoors without proper respiratory protection. In these situations, the lungs can become overwhelmed, leading to rapid inflammation and fluid buildup that may cause severe breathing problems within weeks to a few years of exposure.

For example, researchers in India documented severe acute silicosis cases that occurred after just a few months of exposure to large amounts of silica dust. The CDC reported on cases of severe silicosis among stone fabrication workers in California, Colorado, Texas and Washington.

However, most silicosis cases do not arise from a single incident. Chronic silicosis typically develops after at least 10 years of ongoing exposure to lower or moderate levels of silica dust, while accelerated silicosis appears after several years of high‑level exposure. In other words, for most workers, risk comes from cumulative exposure over time, not from a single brief contact.

Silica dust is dangerous at surprisingly low levels, and there’s no single “safe” amount that protects every worker. How risky exposure is depends on how intense the dust is, how long you’re exposed and whether effective protective measures (like ventilation and respirators) are in place.

In the U.S., federal workplace rules set exposure limits for respirable crystalline silica at 50 micrograms per cubic meter of air, averaged over an eight‑hour workday. But this is meant as a ceiling for typical work shifts, not a guarantee of zero risk. Some experts — such as the American Conference of Governmental Industrial Hygienists (ACGIH) — recommend even lower limits, reflecting growing evidence that harm can occur at or below current regulatory thresholds.

Even lower‑level exposure, repeated over many years of a construction, mining or manufacturing career, can add up to a significant total dose of silica and lead to silicosis, lung cancer or other chronic lung problems.

If you work with concrete, stone or other silica‑containing materials, the early signs of harmful exposure include a cough that doesn’t go away, shortness of breath with routine tasks or being more tired than normal with tasks you aren’t usually tired doing.

These symptoms matter most when they line up with your job history. For example, if you’ve spent years cutting, grinding or sandblasting without consistent dust control or a proper respirator, a persistent cough or new breathing trouble could be a warning that silica dust has started to damage your lungs. The same is true if you feel winded climbing stairs or carrying tools you used to handle easily, or if you’re unusually tired after a normal shift.

Because silica particles are too small to see, you can’t rely on visible dust as a gauge of danger. Instead, treat ongoing respiratory symptoms as a sign to look back at your work tasks, how dusty they were and what protection you had. If your work history includes regular exposure to dust from cutting or drilling quartz countertops, concrete or similar materials, it’s worth talking with a doctor, mentioning possible silica exposure at work and asking about silicosis treatment options.

If your job exposed you to silica dust, you may qualify to file a silicosis lawsuit against your employer, the product manufacturers or others who failed to control dust or warn about the risks. You’re not alone, and workers across the country have filed lawsuits over occupational silica exposure and silicosis.

Recently, two stone fabricators received multi-million dollar verdicts after they claimed engineered stone makers, such as Cambria and Caesarstone, failed to adequately warn them about the high silica content of quartz countertops.

Your first steps are medical and legal. Talk with a doctor about your work history and any symptoms you may have. Ask whether silica exposure should be evaluated. You may also consider speaking with a silicosis lawyer. They can help you gather records about your job duties, dust conditions, protective gear and diagnosis. They can also explain your legal options. These may include workers’ compensation, personal injury or product liability claims. A free case review through Consumer Notice can help you determine if you qualify and connect you with an experienced law firm.

A large group of silicosis cases filed in California has been consolidated in a Judicial Council Coordination Proceeding (JCCP) in California state court. This is a common case‑management process that allows one judge to oversee big‑picture issues for many similar claims, making the litigation more efficient. This JCCP typically only involves cases filed in California, but in some situations, people from other states can join a JCCP. A lawyer can tell you what’s best for your situation.
