Step 6 — Third-Party Claims: When Someone Other Than Your Employer May Be Responsible
A third-party claim is a civil lawsuit against someone other than the employer: a machine manufacturer, an outside contractor working on the site, a property owner, or another business whose conduct may have contributed to the injury. It runs alongside workers' compensation rather than replacing it.
A third-party claim based on negligence requires showing four things: a legal duty owed to the injured person, a breach of that duty, causation (that the breach actually caused the injury) and damages. Whether those elements are met depends on the facts. An injury, however serious, does not by itself prove that anyone was at fault.
Where machinery or equipment is involved, a products-liability claim (a claim that a product was defective and that the defect caused harm) against a manufacturer, distributor or seller may be possible. That framework asks about a defect and causation; an accident involving a machine is not proof that the machine was defective.
Depending on state law, a civil claim may allow damages for medical expenses, lost income, pain and suffering and, where a death occurred, wrongful-death damages, meaning losses the law allows a family to claim after a death. Fault rules also vary; some states use comparative fault, which can reduce a claim by the injured person's own share of responsibility.
Families and injured workers often gather photos and video of the scene and equipment, the equipment itself where it can be kept, maintenance and inspection records, incident reports and witness names.
What is at stake is time and proof. Limitation periods for civil claims differ by state, and the one that applies depends on the facts and the state. The site's page on the industrial accident attorney role describes who may be answerable by type.
