Yes, very likely, if you cut, grind, or drill concrete, stone, brick, or engineered quartz without dust control. That dust contains respirable crystalline silica, particles small enough to reach deep into your lungs and scar them permanently. The disease it causes, silicosis, has no cure. You often feel nothing for years, and by the time you are short of breath, the damage is already done. Quartz (engineered stone) countertop work is the most dangerous version of this, and it is putting young workers in their 30s and 40s on lung transplant lists right now.
What silica does to your lungs
Respirable crystalline silica is the fine dust released when you work anything with quartz in it: concrete, mortar, brick, block, stone, tile, and engineered quartz. The particles are too small to see or feel, and your body cannot clear them. They lodge in the lung and trigger scarring (fibrosis) that never heals.
That scarring is silicosis, and it comes in three forms depending on how much dust and how fast:
- Chronic silicosis builds over 10 or more years of moderate exposure. This is the classic version, slow and often silent until it is advanced.
- Accelerated silicosis shows up in 5 to 10 years with heavier exposure and moves faster.
- Acute silicosis can hit in weeks to months under extremely high exposure. It progresses fast and it kills. This is the form now devastating engineered-stone countertop fabricators.
Silica does not stop at silicosis. It also raises your risk of lung cancer, tuberculosis, COPD, and kidney disease. There is no treatment that reverses any of it. The only lever is stopping the dust before it gets into you.
Engineered quartz countertops are the emergency
If you fabricate engineered stone countertops, this section is aimed straight at you. Engineered stone marketed as "quartz" is roughly 90 to 95 percent crystalline silica, far more than natural granite or concrete. Cutting, grinding, and polishing it dry throws off dust at concentrations that can overwhelm even a respirator worn correctly.
The result is a real, documented outbreak, not a scare story:
- As of May 15, 2026, the California Department of Public Health had confirmed more than 560 engineered-stone silicosis cases and 31 deaths among countertop workers since surveillance began in 2019. The median age at diagnosis was 46, and at death, 48. These are young men.
- An earlier CDPH count on November 13, 2025 had 432 cases, 25 deaths, and 48 workers who needed a lung transplant.
- Nationally, by November 2024 the total across reporting states had reached 219 confirmed cases including at least 14 deaths and 26 lung transplants. California's numbers run higher mostly because it made silicosis a reportable disease in 2025, so it actually counts cases that most states never record.
Australia banned engineered stone containing high levels of silica in 2024 after its own cluster of cases proved the dust controls were not enough. In the US, California's standards board voted in May 2026 to direct Cal/OSHA to draft an emergency standard that would prohibit fabricating engineered stone above 1 percent crystalline silica, which would be the first ban of its kind in the country. Federal OSHA has not banned it. Its silica rule still applies, and for high-silica engineered stone that means wet methods, ventilation, and, realistically, a powered air-purifying respirator (PAPR) rather than a standard half-face mask.
You will not feel the early damage
The cruel part of silicosis is that early on it is quiet. There is no cough that says "this is silica," no pain that warns you in time. Symptoms like shortness of breath on exertion, a lingering cough, chest tightness, and fatigue tend to show up once scarring is already established. That is exactly why you cannot judge your risk by how you feel today.
If you have done years of dusty cutting, grinding, or fabrication, do not wait for symptoms to get checked.
Screening: what to ask for and why
Screening does not undo damage, but it catches disease earlier, tracks whether it is progressing, and builds the medical record you need if you ever file a claim. The core tests for silica are:
- A chest X-ray read by a NIOSH-certified B Reader. A B Reader is specially trained to spot the pattern of dust-related lung scarring, and they are the right person to interpret these films. A regular X-ray read by a general radiologist can miss early changes.
- Spirometry (a pulmonary function test), which measures how well your lungs move air and can show loss over time.
- A tuberculosis test, because silica raises TB risk.
If you have to wear a respirator for silica work for 30 or more days in a year, your employer owes you this medical surveillance at no cost to you, and the detailed findings stay confidential to you. The mechanics of that requirement live in the silica standard guide. Separately, if you have a significant smoking history, low-dose CT lung cancer screening (which NCCN guidelines suggest from age 50 for a 20 pack-year history) is more sensitive than an X-ray, so raise your silica exposure with your doctor when you discuss it.
Stopping the dust is the whole game
Because nothing reverses silicosis, prevention is not a nice-to-have, it is the only real protection. The dust controls that work are wet cutting, tools with shrouds and a HEPA vacuum, good ventilation, and proper respiratory protection when you cannot knock the dust down at the source. OSHA's silica standard spells out exactly which controls go with which task through its Table 1 shortcut. The full how-to, including when a respirator is required and what Table 1 demands, is in the silica standard guide. Read it, because that is where the life-saving is.
Common questions
Can silicosis be cured?
No. Silicosis is permanent and there is no cure. The scarring in your lungs does not heal, and treatment can only manage symptoms and slow further harm. Removing yourself from silica exposure stops it getting worse from new dust but does not reverse what is there. That is why prevention, controlling the dust before you breathe it, is the only real protection, and why "just a bit of dust" is the wrong way to think about it.
Is cutting quartz countertops more dangerous than cutting concrete?
Yes, considerably. Engineered quartz is about 90 to 95 percent crystalline silica, far more than concrete or natural stone, so fabricating it dry releases much heavier dust. That is why countertop fabricators are turning up with fast, severe silicosis in their 30s and 40s, some needing lung transplants. If you fabricate engineered stone, wet methods, strong ventilation, and often a powered air-purifying respirator (PAPR) rather than a basic mask are the baseline, not the extras.
What are the early signs of silicosis?
Often there are none until the disease is advanced, which is what makes it so dangerous. When symptoms do appear they include shortness of breath on exertion, a persistent cough, chest tightness, and fatigue. Because you cannot rely on how you feel, anyone with years of dusty cutting, grinding, or stone fabrication should get lung screening rather than wait for symptoms. This is general information, so see a doctor about your own risk.
How do I get tested for lung damage from silica?
Ask for a chest X-ray read by a NIOSH-certified B Reader, a spirometry (pulmonary function) test, and a tuberculosis test. A B Reader is trained to spot dust-related lung scarring that a general read can miss. If you wear a respirator for silica work 30 or more days a year, your employer must provide this surveillance at no cost. If you also have a smoking history, ask your doctor about low-dose CT screening, which is more sensitive than an X-ray.
Does engineered stone get banned in the US?
Not federally, as of 2026. California moved first: in May 2026 its standards board directed Cal/OSHA to draft an emergency standard prohibiting fabrication of engineered stone above 1 percent crystalline silica. Australia banned high-silica engineered stone in 2024. Until any US ban is final, federal OSHA's existing silica rule governs, which means wet cutting, ventilation, and respiratory protection are required, not optional. Check Working in Your State for where your state stands.
The honest bit
- The engineered-stone case counts here are from the California Department of Public Health and are current as of May 2026. They keep rising, and most states do not track silicosis at all, so the true national number is higher than any published figure. Verify current data at cdph.ca.gov and cdc.gov/niosh.
- This guide teaches the health side. The legal dust limit, Table 1 controls, and respirator rules are federal OSHA and live in the silica standard guide. State-plan states can require more, and California may ban engineered-stone fabrication outright, so check Working in Your State.
- This is general information, not medical advice. If you have done dusty work, or you have a cough or breathlessness that will not settle, see a doctor and tell them about your exposure. Early screening changes what your doctor can do for you.
