Silicosis and Occupational Lung Disease Workers' Comp in California — Stone-Fabrication Industry Claims

How do you prove silicosis came from your job?

You show your work history and your dust exposure. Then a doctor links your scarred lungs to that silica dust. Medical proof drives the case.

Silicosis builds slowly. You may have breathed the dust for years. So the law treats it as a cumulative injury. It is not a one-day accident. That is normal for lung disease.

Engineered stone is the worst source. It is the quartz used for kitchen counters. It holds far more silica than granite. Cutting it dry throws clouds of fine dust. Many shops skip the water and masks that block it. That is why young workers get sick so fast. State dust rules require water and good masks. Too many shops ignore them.

These jobs carry the highest risk:

• Stone and quartz countertop fabricators
• Concrete cutters and grinders
• Sandblasters
• Foundry and glass workers
• Masons, tile setters, and tunnel crews

The proof has two parts. First, your job history. We show where you cut, ground, or polished stone. Second, the medical link. A doctor reviews your lung scans, your breathing tests, and your dust history. A neutral doctor called a QME often weighs in. If you have a lawyer, both sides can agree on one shared expert. It is called an AME.

Picture a fabricator who cut quartz for six years. The shop ran dry saws with no water. He now needs oxygen at night. His scans show classic silica scarring. That is a strong, provable claim. We line up the exposure proof and the medical proof together. We gather shop records, safety data, and old pay stubs.

What benefits can you get for occupational lung disease?

Three things: all your lung care paid for life, two-thirds of your wages while off work, and a cash award for permanent lung damage.

Your lung care is covered in full under Labor Code 4600. That means scans, breathing tests, oxygen, specialists, and medicine. Silicosis does not heal. So this care lasts for life. You never pay a copay.

While your lungs keep you off work, you get temporary disability pay. It replaces two-thirds of your wages. Under Labor Code 4656, this pay has a time cap. The first table shows the rates and the limit.

Scarred lungs often leave lasting damage. That earns a permanent disability award. Serious lung disease rates high. A rating of 70 percent or more adds a lifetime life pension.

Once your lungs are as stable as they will get, a doctor scores the damage. That score sets your weeks of pay. Older age and a harder job can push it up. The next table shows what higher ratings pay.

Silicosis may push you out of dusty work for good. If your old employer cannot take you back, you can get a retraining voucher. It helps pay for a new trade or school.

When does the clock start on a silicosis claim?

The clock for a slow disease starts when two things meet: real disability and knowing the dust caused it. Often that is diagnosis day.

Many silicosis workers fear they waited too long. Usually you have not. For a slow disease, the law sets a special start date. It is Labor Code 5412. Your clock starts when you are disabled and you learn work caused it.

So your dusty job may have ended years ago. Your deadline can still be open. You tell your employer within 30 days of that start date. You file your claim within one year, under Labor Code 5405. The table lays out each clock.

After you file, the insurer must decide fast. Your care keeps flowing while they review. We map your work history shop by shop. Then we lock in the right date. Do not guess on your timeline. One free call sorts it out.

Can the insurer blame your smoking to cut the award?

They can try. It is called apportionment. By law their doctor must prove the exact share from smoking, not just guess at it.

The biggest fight is over cause. The insurer may say smoking hurt your lungs, not dust. Every share they pin on smoking is money they keep. So this fight is really about your award.

The law does not let them guess. Under Labor Code 4663, their doctor must show the real medical split. How much came from silica dust. How much from anything else. And the reason for each share. A bare claim of smoking does not count.

Here is the good news. Silica dust is a known, clear cause of this scarring. Its damage has a telltale look on a lung scan. A skilled expert can tell dust damage from smoking damage. So the work share is often large. That puts most of the award on the insurer, not on you. In the worst cases, the lungs fail and need constant oxygen. Those claims rate among the highest.

The insurer may also deny a treatment your doctor orders. Maybe a scan or a new drug. You can appeal that through a review called Independent Medical Review. You have 30 days to ask. We file the appeal and push back fast.
