If the nail gun's safety mechanism failed, your case is not dead just because you kept using it.

That's the first thing.

A lot of owners in South Bend do the same thing: keep the crew moving, finish the punch list, deal with the bad tool later. You've got five employees waiting on payroll, maybe a job off Lincoln Way or near Mishawaka, and nobody has time for a perfect safety memo. Then the gun double-fires or shoots when the nose piece wasn't supposed to engage, and now your hand, leg, or knee is torn up.

Indiana does not automatically treat that as "your fault" because you knew the tool was acting weird.

Partial blame is a problem, but not always the whole problem

Indiana uses modified comparative fault. In plain English, if a jury says you were more than 50% at fault, you're out. If you were 50% or less at fault, your recovery gets reduced by your share.

So yes, the defense will absolutely argue you should have tagged the tool out, replaced it, or stopped using it. That's the ugly part.

But with a defective safety mechanism, the bigger question is whether the gun was unreasonably dangerous when it left the manufacturer or seller. A contact-trip trigger that fires when it shouldn't, a worn or defective nose safety, or a design that allows an unintended discharge can shift the focus back where it belongs: the product.

That matters whether the job was on a remodel near Notre Dame, a commercial build on the south side, or a residential site out toward Granger.

The missing doctor notes are fixable, but only if you move fast

Incomplete medical records can wreck a good injury case because the insurer starts saying the injury wasn't that serious, or the mechanism of injury is "unclear," or the surgery was for something preexisting.

In South Bend, that can happen if you bounced from an urgent care to Memorial Hospital, then to an orthopedic follow-up, then physical therapy, and one chart never got scanned correctly. Spring is busy, construction picks up, and records get sloppy. Nobody at the carrier gives a damn that your charting error was somebody else's mistake.

What helps is rebuilding the medical story from every other source around the bad chart:

• ER triage notes, ambulance run sheets, X-rays and radiology reports, operative reports, discharge instructions, work restrictions, PT intake forms, prescription history, billing codes, and photos of the wound or swelling taken the same day

Those records often say more than one thin office note ever would.

If the treating doctor's chart is missing the part where you explained the misfire, look at the radiology order. Look at the emergency department history. Look at the first PT evaluation. Those places often document "nail gun accidental discharge" or "injury from defective tool" in cleaner detail than the later specialist note.

A product claim is different from a workers' comp fight

For a small business owner, this gets messy fast.

If you were physically doing the work with your crew, there may be a workers' comp issue depending on how your business is set up and how coverage was elected. But a defective-tool claim against the manufacturer, distributor, or seller is a separate lane. Homeowner insurance saying "this is the company's problem" does not answer the product-defect issue at all.

And if this happened on a customer's property, preserving the actual nail gun matters more than almost anything. Don't let it disappear into a truck bin, get "repaired," or get tossed after the site gets cleaned up. The defense would love that.

What usually makes or breaks this kind of claim

The strongest cases are the ones that can show a straight line from bad tool to injury to treatment.

That line does not have to be perfect. It does have to be documented.

Witness statements from your crew matter. So do text messages sent right after the injury. If you called your spouse or foreman and said, "The damn safety on this gun failed again and it shot me," that is useful. If one of your five employees saw the nose piece not seat correctly or saw the gun fire unexpectedly, that matters too.

Indiana generally gives you two years for a product-liability injury claim, but waiting is stupid in a case like this because evidence goes bad fast. Tools get replaced. Jobs wrap. People forget. Lake-effect weather doesn't hit South Bend like Gary gets buried, but even one wet spring week can scatter a site and half your proof with it.

And if the chart is incomplete, delay makes that worse. The longer you wait, the easier it is for everyone else to say they just don't remember what happened.
