1 Year or 2 Years? Industrial Injury and Occupational Disease Claims Run on Different Clocks in Washington

An industrial injury claim has to be filed within one year. An occupational disease claim gets two years. Which clock applies depends on how L&I classifies the claim, and in Washington, that classification is usually made once and generally cannot be reopened for a different one later.

Washington law draws a specific legal line between the two. An industrial injury is “a sudden and tangible happening of a traumatic nature, producing an immediate or prompt result,” under RCW 51.08.100, the kind of thing a fall, a machinery accident, or a single lifting injury produces. An occupational disease is “a disease or infection that arises naturally and proximately out of employment,” under RCW 51.08.140, the kind of thing that develops from repeated exposure or conditions over time, such as a lung condition from chemical exposure or hearing loss from sustained noise.

The Two Different Filing Deadlines

• Industrial injury claim: must be filed within one year of the date the injury occurred.
• Occupational disease claim: must be filed within two years of the date a physician gives the worker written notice that both confirms the disease and states that disability benefits may be filed for it, not simply the date of an initial diagnosis.

Getting the classification wrong at filing can mean applying the wrong deadline to a claim, which is why the distinction matters well before any dispute over benefits comes up.

Why the Classification Gets Decided Once, Not Twice

The standard courts use to sort a condition into one category or the other depends on whether it came from a specific traumatic event, or from the distinctive conditions of the job generally. Once L&I issues a final order classifying a claim one way, a worker generally cannot later ask to reclassify it into the other category, even if new medical evidence would have supported it, according to legal analysis of the rule. That makes the initial classification a decision worth getting right the first time, not something to revisit after the fact.

Repetitive Trauma Sits in a Gray Area

Injuries from repeated motion, such as carpal tunnel syndrome from repetitive tasks or a rotator cuff injury from repeated heavy lifting, don’t come from one identifiable event, so Washington generally treats them as occupational disease claims rather than industrial injury claims. That classification affects both the filing deadline and the medical evidence needed to support the claim, since an occupational disease claim has to show the condition came from the distinctive conditions of the job rather than from an ordinary risk of everyday life.

If a Work-Related Condition Causes a Worker’s Death

Surviving family members can file a claim within one year of the worker’s death, even if the condition itself would otherwise have had a different filing window, as long as they can show the death was connected to the work-related injury or disease.

Do You Have Legal Options?

A claim filed under the wrong classification, or filed after its actual deadline has passed, can be denied on a technicality before anyone even reviews the medical facts. Workers with a condition that developed gradually, rather than from one clear incident, may have options worth discussing with an attorney before filing.

FAQ

What’s the real difference between an industrial injury and an occupational disease claim?

An industrial injury comes from a specific, sudden event, like a fall or a machinery accident. An occupational disease develops gradually from the conditions of the job itself, like repeated chemical exposure or sustained loud noise. Washington law defines each separately, and they run on different filing deadlines.

How long do I have to file each type of claim?

An industrial injury claim is due within one year of the injury. An occupational disease claim is due within two years of getting written notice from a physician or licensed advanced practice registered nurse confirming the disease and that benefits may be filed for it.

Is carpal tunnel or a rotator cuff injury an industrial injury or an occupational disease?

Washington generally classifies repetitive-motion conditions like these as occupational disease claims, since they develop from repeated job tasks rather than one traumatic event. That affects both the deadline and the medical proof needed.

Can I change my claim from one category to the other later?

Generally, no. Once L&I issues a final order classifying a claim as an industrial injury or an occupational disease, that classification typically stands, even if later evidence would have supported the other category. That makes it important to get the classification right at filing.

Should I talk to an L&I attorney?

If a condition developed gradually rather than from one clear incident, if a filing deadline is approaching, or if a claim was denied over its classification, it’s worth a conversation before filing or before that decision becomes final.
