Engineered Stone Silicosis: What California Workers Can Recover

If you’ve spent years cutting, grinding, or polishing quartz countertops in Southern California, you may already know something is wrong. The cough that won’t quit. The shortness of breath. The fatigue that makes it hard to get through a shift.

What you may not know is that you could be one of hundreds of workers in California who have developed silicosis — an incurable, often fatal lung disease — from breathing in the fine crystalline silica dust released every time engineered stone is cut.

And California may be on the verge of banning the material entirely.

What Is Engineered Stone — and Why Is It Deadly to Work With?

Engineered stone — also marketed as quartz, artificial stone, or composite countertops — became the most popular countertop material in the U.S. over the last decade. It’s affordable, durable, and visually consistent. But beneath its polished surface is a serious danger: most engineered stone slabs contain more than 90% crystalline silica, the most hazardous form of the mineral.

When workers cut, shape, grind, or polish these slabs, a fine toxic dust is released into the air. Breathe enough of it, and those microscopic particles scar your lungs from the inside — permanently.

To understand why engineered stone is so much more dangerous than natural materials, the silica content difference is stark:

California’s Silicosis Epidemic: The Numbers Are Staggering

California is currently the only state actively tracking silicosis cases among countertop workers. According to Public Health Watch, as of April 8, 2026:

• 542 confirmed silicosis cases statewide — up from just 69 in 2022
• 29 workers have died
• 279 cases — more than half — come from Los Angeles County alone

The majority of affected workers are young Latino immigrant men, many of them working in the San Fernando Valley. Some were diagnosed with advanced silicosis in their 20s. A number have required double lung transplants just to survive.

Occupational health experts warn the confirmed numbers are almost certainly an undercount. A 2023 Australian silicosis screening study found that nearly one in four workers fabricating engineered stone had the disease. Applying similar rates to California, state regulators estimate that out of approximately 4,600 stone fabrication workers in the state, between 485 and 848 will develop silicosis — and as many as 161 could die from it.

Silicosis is progressive and incurable. There is no treatment that reverses the scarring. The only options are supplemental oxygen and, in severe cases, a lung transplant.

California Is Now Considering a Full Ban

In December 2025, the Western Occupational and Environmental Medical Association — a nonprofit representing more than 600 physicians and health experts across seven states — petitioned California’s Occupational Safety and Health Standards Board to prohibit all fabrication and installation work on engineered stone containing more than 1% crystalline silica.

The Standards Board is expected to vote on whether to advance the proposal at its May 21, 2026 meeting in Los Angeles. If approved, it would kick off a formal rulemaking process — and California would become the first U.S. state to ban the material.

The medical community pushing for the ban argues that safety controls alone are not working. Cal/OSHA inspectors have found that approximately 95% of fabrication operations they’ve visited were not in compliance with all of California’s safety rules — and even facilities recognized as industry models are still seeing workers get sick.

The precedent has already been set internationally: Australia banned engineered stone in July 2024, after an outbreak that claimed an estimated 1,000 victims. After the ban, safer low-silica and silica-free alternatives entered the Australian market without significant disruption to the industry.

The Industry Is Fighting Back — in Congress

While California considers a ban, the engineered stone industry has taken its fight to Washington. In January 2026, manufacturers — led by Minnesota-based Cambria — testified before Congress in support of H.R. 5437, a bill that would:

• Eliminate the right of sick workers to sue stone manufacturers and distributors
• Retroactively dismiss hundreds of pending lawsuits already filed by fabricators with silicosis

Manufacturers argue that liability belongs with the fabrication shops that failed to follow safety protocols — not with the companies that made and sold the material. Public health experts counter that the material itself is too dangerous to be safely handled regardless of protocols, and that stripping litigation rights removes the single most powerful incentive for manufacturers to make safer products.

If this bill passes, it could permanently shut the courthouse door for workers who are already sick.

If You Work With Engineered Stone, Here Is What You Need to Know

You Likely Have More Than One Legal Claim

Many workers assume workers’ compensation is their only option. It isn’t. California law gives you two separate and simultaneous paths to compensation:

Workers’ comp does not bar a product liability suit. You can pursue both at the same time, and in silicosis cases, the product liability claim often produces significantly greater recovery.

What Manufacturers Are Being Sued For

Lawsuits across California allege that engineered stone manufacturers knew — or should have known — their products were deadly to fabrication workers and concealed those risks. Common claims include:

• Failure to warn — manufacturers did not disclose the silica hazard to workers or distributors
• Defective product design — the material is inherently unsafe for fabrication regardless of precautions taken
• Fraudulent concealment — some manufacturers are alleged to have suppressed knowledge of international silicosis clusters before the California epidemic became public

A California jury recognized the strength of these claims in August 2024, awarding $52.4 million to a 34-year-old fabricator who required a double lung transplant — the first verdict of its kind in the nation.

Your Immigration Status Does Not Affect Your Rights

California product liability law protects all workers on U.S. soil, regardless of immigration status. Your status cannot be used as a defense by stone manufacturers, and it cannot be used to deny you compensation.

The Discovery Rule May Extend Your Deadline

California generally allows two years to file a personal injury claim — but silicosis is different. The discovery rule starts the clock from when you knew or reasonably should have known that your lung disease was caused by engineered stone exposure — not from when you first developed symptoms. Many workers were never told what they were being exposed to. Do not assume you’ve missed your window before speaking with an attorney.

Symptoms to Watch For

Silicosis does not always announce itself immediately. Seek medical attention if you experience any of the following:

Early warning signs:

• Persistent cough
• Shortness of breath during physical activity
• Fatigue and weakness
• Chest tightness

Advanced-stage symptoms:

• Chest pain
• Night sweats and unexplained weight loss
• Cyanosis (bluish skin from low oxygen)
• Respiratory failure

If you’ve worked cutting or polishing engineered stone and have any of these symptoms, see a doctor and ask specifically about silicosis. Request high-resolution CT imaging — it is significantly more sensitive than a standard chest X-ray for detecting this disease.

This Is Not an Individual Failure — It’s a System Failure

The workers at the center of California’s silicosis epidemic did not make reckless choices. They went to work every day, often without being told what they were being exposed to. Many used the protective equipment they were given. Some worked in facilities that were recognized as industry models of safety — and still got sick.

The companies that manufactured and sold engineered stone knew what the science showed. They sold a product containing 90%+ crystalline silica to an industry of small fabrication shops, many of them under-resourced and under-informed, without ever putting a stop to it.

That is the kind of corporate negligence that belongs in a courtroom.
