When Do I File a CA-1 Instead of a CA-2?

A CA-1 generally applies to a traumatic injury that happens within one workday or shift. A CA-2 generally applies to an occupational illness or condition that develops from work exposure over more than one shift. The distinction is about the time involved, so an injury does not need a dramatic accident to belong on a CA-1.

Does a CA-1 Require One Sudden Incident?

No. Lifting a box and immediately hurting your back is one example, but it is not the only one. Repeated lifting during a single shift may also fit the traumatic-injury category if the injury developed within that shift.

That is why a clear description of what happened matters. The form should reflect the work activity and the period of exposure, rather than just the name of the diagnosis.

When Would a CA-2 Apply?

A CA-2 generally covers work exposure extending beyond one shift. Repeated lifting over several days is one possible example. A condition connected to a longer period of environmental exposure may also fall into this category.

Your medical evidence still needs to support the connection between your work and the diagnosed condition. Choosing the right form is one part of presenting the claim.

Why Does the Difference Matter for Pay?

An eligible traumatic injury may qualify for up to 45 calendar days of continuation of pay from the employing agency. Occupational-disease claims do not carry that same continuation-of-pay benefit, although OWCP wage-loss benefits may be available when the requirements are met. OWCP explains these distinctions in its new-claim guidance.

What If I Am Unsure Which Form Fits?

Write down what you were doing, when the exposure began, and when symptoms developed. Those details help clarify whether the claim involves one shift or a longer period. If the form and the facts do not match, ask for help addressing the discrepancy instead of assuming that the form alone settles your eligibility.
