Silica Dust and Lung Cancer: Your Legal Options in New York

If you spent years cutting countertops, working construction, or running equipment in a foundry, you probably went home covered in fine gray dust more times than you can count. Most workers never thought twice about it.

That dust was also settling deep in your lungs, and for a growing number of workers it is now tied to a lung cancer diagnosis that arrived years later.

This guide explains how silica causes lung cancer, which jobs carry the most risk, what employers are required to do, and how New York law handles these claims.

How Silica Dust Causes Lung Cancer

The National Toxicology Program lists respirable crystalline silica as known to be a human carcinogen, and the International Agency for Research on Cancer has classified it as a cause of human lung cancer since 1997.

The American Cancer Society lists silica among the workplace exposures that raise lung cancer risk.

Once silica particles lodge in the lungs, they injure the lining of the airways and trigger chronic inflammation and oxidative damage. The NTP explains that this persistent inflammation can lead to genetic damage in lung tissue, which is one way silica is thought to cause cancer.

The NTP summarizes the overall increase in lung cancer risk among exposed workers at roughly 30 to 50 percent, with higher risk for workers who had heavier or longer exposure.

Among workers who also have silicosis, the risk is roughly two to four times higher. Those are relative comparisons, not the share of workers who develop cancer.

Why Countertop Workers Are Getting Sick So Young

Engineered stone is made by crushing quartz into powder and binding it with resin and pigments. According to the 2026 OSHA and NIOSH hazard alert on countertop work, some engineered stone contains up to 95 percent crystalline silica.

That compares with up to 50 percent for granite and less than 5 percent for marble and limestone. Silica content does vary by product, and some newer engineered stones contain far less.

The percentage describes the slab, not the air a worker breathes. The danger comes from cutting, grinding, and polishing, which release the dust. An installed countertop in a kitchen does not create the same exposure.

For a worker who later develops lung cancer, the engineered stone pattern matters for another reason. The exposure is often easier to trace than in older industrial cases, because there is a manufacturer that made the slabs, a distributor that sold them, and a shop where the cutting happened.

What Smoking Means for a Silica Claim

Smoking does not rule out a silica claim. The 2020 pooled analysis found that silica and smoking together raised lung cancer risk by more than the two risks multiplied, which means a smoker with heavy silica exposure faces a far higher risk than either exposure alone would predict.

The New York City advisory makes the same point in clinical terms, warning that smoking compounds the effects of silicosis.

Expect the defense to raise a smoking history anyway. A claim will need medical evidence that addresses smoking directly rather than ignoring it.

Lung cancer from silica usually appears years or decades after the exposure. A worker who left a dusty job long ago can still receive a diagnosis that traces back to it.

What OSHA Requires Employers to Do

OSHA has two silica standards: 29 CFR 1910.1053 for general industry and maritime work, which covers most fabrication shops, and 29 CFR 1926.1153 for construction.

Both set a permissible exposure limit of 50 micrograms of silica per cubic meter of air, averaged over an eight-hour shift, with an action level of 25 micrograms. Most construction obligations began in June 2017, and most general industry obligations in June 2018.

When it issued the rules, OSHA estimated they would save more than 600 lives and prevent more than 900 new silicosis cases each year once fully in effect.

Under both standards, employers must:

• Use water, ventilation, and other engineering controls to keep exposure at or below the limit

• Provide respirators where those controls are not enough

• Keep a written exposure control plan and train workers on the hazard

• Avoid dry sweeping and compressed-air cleaning where they spread dust

• Offer free medical exams that include a chest X-ray read by a certified B reader and a lung function test

The two standards differ in ways that matter later. Construction employers can either follow OSHA's Table 1, which specifies controls and respirators for listed tasks, or measure exposure directly, and they must designate a competent person to inspect job sites.

In construction, medical exams are required for workers who must wear a respirator for 30 or more days a year; in general industry, for workers exposed at or above the action level for 30 or more days a year.

Employers who measure exposure must tell workers the results within five working days in construction and 15 in general industry.

Employers must also keep air monitoring and medical surveillance records, which can become important evidence years later.

OSHA's chest X-ray is occupational surveillance, not lung cancer screening. The New York City advisory notes that a high-resolution CT scan is the gold standard for evaluating silicosis.

Can You Get Compensation for Silica-Related Lung Cancer?

In New York, there are usually two paths: a workers' compensation claim against your employer's insurance, and a lawsuit against companies other than your employer.

Workers' compensation

Workers' compensation pays medical costs and part of your lost wages without requiring proof that your employer did anything wrong. It still requires proof that your illness came from your work. Under Workers' Compensation Law § 11, it is generally your only remedy against your own employer, unless the employer failed to carry workers' compensation insurance.

New York's law gives silica cases some specific help.

Under Workers' Compensation Law § 47, any exposure to harmful dust in New York lasting 60 days is presumed to be an injurious exposure unless there is substantial evidence otherwise. When the disease is silicosis or another dust disease, the employer where you were last exposed is generally the one responsible for the claim.

The filing deadline accounts for the long delay before diagnosis. Workers' Compensation Law § 28 names silicosis, other dust diseases, and occupational malignancies among the diseases that can be claimed after the usual two-year limit. The claim must be filed within two years after disablement and after you knew or should have known the disease was caused by your work.

The New York City advisory stresses a point many workers do not know: every employee in New York has the same right to workers' compensation benefits and medical care regardless of immigration status.

Lawsuits against other companies

Many silica-exposed workers have claims against companies other than their employer: the manufacturer of the engineered stone, a supplier of sand or other silica products, a distributor, or a contractor or property owner who controlled the worksite.

These third-party claims can recover damages that workers' compensation does not pay, such as pain and suffering.

Under Workers' Compensation Law § 29, you can collect workers' compensation and pursue a third-party lawsuit at the same time. The compensation carrier has a lien on any recovery for what it has paid, and settling for less than the compensation owed generally requires the carrier's written consent or a court order.

These cases turn on scientific proof that you were exposed to enough silica to cause your cancer. Our guide to proving a workplace chemical caused your cancer explains the causation standard New York courts apply.

A pending federal bill could affect engineered stone lawsuits

H.R. 5437, the Protection of Lawful Commerce in Stone Slab Products Act, would bar certain lawsuits against manufacturers and sellers of stone slabs over silica exposure that happens during fabrication.

According to the Congressional Budget Office, it would also require dismissal of pending cases that meet its criteria. The House Judiciary Committee approved it 16 to 7 on June 3, 2026. As of mid-October 2026, it had not passed the House or become law.

How Long You Have to File a Lawsuit

Under CPLR 214-c, a lawsuit for the delayed effects of a toxic exposure generally must be filed within three years of the date you discovered the injury, or should have discovered it.

The clock runs from discovery, not from the date of exposure, which matters for a disease that takes years to appear.

The catch is what counts as discovery. New York's highest court has held that the clock starts when you notice the symptoms of the illness, even if you do not yet know what caused them. Waiting until you connect a cough or a diagnosis to your old job can cost you the claim.

The statute does offer one narrow extension. If you discover the cause within five years of discovering the injury, you may get one more year from that point, but only if you can show the scientific knowledge needed to identify the cause was not available earlier.
