Silicosis Lawsuits Highlight New and Deadly Risk Facing Engineered Stone Workers

A preventable lung disease caused by exposure to silica dust is spreading among workers who cut and install artificial stone countertops. Silicosis, a disease once associated solely with miners and sandblasters, is now striking men in their 30s and 40s who cut, grind and polish engineered stone slabs for kitchens, baths and other construction applications. Public health agencies and authorities tracking the outbreak agree that California sits at the center of the crisis.

What is Silicosis?

Silicosis is an incurable, progressive interstitial lung disease caused by silica dust exposure. According to the Cleveland Clinic, the disease scars lung tissue and gradually robs the lungs of their ability to move oxygen into the blood. Medication is unable to reverse the damage, and treatment is limited to supporting a patient, ranging from bronchodilators and supplemental oxygen to lung transplantation in advanced cases.

Silica itself is one of the most common minerals on earth, found in sand, granite, quartz and concrete. Exposure to silica is dangerous when it is broken into fine, breathable dust during cutting, grinding, drilling or polishing of engineered stone products.

How Does Silicosis Develop?

When inhaled, silica dust lodges deep in the air sacs of the lungs. Immune cells try to clear the particles from inside the lungs and become damaged, triggering inflammation and scar tissue called silicotic nodules. Over time, those nodules stiffen the lungs and shrink their capacity.

The Cleveland Clinic notes that traditional, chronic silicosis usually requires a decade or more of routine exposure, but exposure to silica from engineered stone is different. The CDC’s National Institute for Occupational Safety and Health (NIOSH) reports that engineered, or “artificial,” stone is typically more than 90% crystalline silica, a far higher concentration than what’s found in granite or marble. That density produces dust loads heavy enough for fabricators to develop a severe, accelerated form of silicosis. The American Prospect reports this faster-moving disease has killed at least 29 California stoneworkers and sickened hundreds more.

How is Silicosis Diagnosed?

There are few early signs or symptoms of silicosis, which is one reason workers are typically diagnosed only after significant lung damage has occurred. As the disease progresses, common warning signs include:

• Shortness of breath (especially during heavy activity)
• A persistent cough
• Chest tightness
• Fatigue
• Unexplained weight loss
• Night sweats
• Bluish tint to the lips or fingertips (in late stages), signaling low oxygen

Diagnosis usually involves a detailed work history, a chest X-ray or CT scan and pulmonary function testing. Anyone who has worked with engineered stone, even briefly, should tell their physician, because silicosis symptoms and diagnostic imaging can be misread without that context.

Who is Most Vulnerable to Silicosis?

The engineered stone outbreak has fallen hardest on countertop fabricators, the workers who cut and polish slabs before installation. California state data show more than 480 silicosis diagnoses over roughly seven years, with at least 27 confirmed deaths. 

Jobs that cause silicosis and those at risk include:

• Young, Latino and immigrant fabricators in their 30s or 40s
• Long-tenured stoneworkers exposed daily to slabs that exceed 90% crystalline silica
• Family members exposed to secondhand silica dust carried home on clothing

California enacted the nation’s first state law to protect engineered stone workers, effective Jan. 1, 2026. Authorities disagree whether tighter rules are enough or whether a full ban on engineered stone, like one in place in Australia, are needed. Anyone in California, Oregon or Washington who has worked with engineered stone and has trouble breathing should see a pulmonologist familiar with occupational lung disease soon. Early diagnosis cannot reverse silicosis, but it can slow its progression.
