Hurt by Defective Equipment at Work: Third-Party Claims

Workers’ compensation pays regardless of fault, but it comes with a tradeoff most injured workers don’t learn about until later: no pain and suffering, and everything else capped or formula-limited. When the injury was actually caused by a defective tool, machine or piece of equipment — not just an ordinary workplace accident — a separate path exists that doesn’t carry those limits.

Quick answer: If defective equipment caused your injury, you can typically pursue both a no-fault workers’ comp claim against your employer and a separate product liability claim against the equipment’s manufacturer, distributor or seller. The product liability claim can recover pain and suffering and full damages that workers’ comp does not provide — but your workers’ comp carrier will usually have a subrogation claim against whatever you recover.

Two Separate Claims, Two Separate Recoveries

• Workers’ compensation is a no-fault claim against your employer’s coverage — you don’t have to prove anyone was negligent, but you generally cannot recover pain and suffering, and everything else follows your state’s benefit schedule. See our workers’ comp settlement amounts guide for how that side of the claim is valued.
• Product liability is a fault-based claim against whoever designed, manufactured, distributed or sold the defective equipment — not your employer. It can recover full economic damages plus pain and suffering, without the caps and formulas that apply to workers’ comp.

Pursuing both is not double-dipping — they compensate for different things, through different legal theories, against different parties.

What Makes Equipment “Defective”

Product liability claims generally fall into one of three categories, and which one applies changes both the evidence needed and who the right defendant is:

1. Design defect — the product is unreasonably dangerous even when manufactured exactly as intended, because a safer, feasible alternative design existed.
2. Manufacturing defect — the design itself was sound, but this specific unit was flawed due to an error in production, making it more dangerous than others of the same design.
3. Failure to warn — the product lacked adequate instructions or warnings about a hazard that wasn’t obvious to an ordinary user, even though the product itself functioned as designed.

A missing safety guard, a failure to disengage automatically, inadequate lockout/tagout warnings, or a design that made an obvious hazard unnecessarily likely are all common fact patterns in workplace equipment cases.

A machine that met OSHA’s machine-guarding requirements can still be defectively designed, and vice versa. OSHA regulates your employer, not the manufacturer of equipment already sold — so an OSHA violation doesn’t itself establish the manufacturer’s liability. What OSHA standards (such as the machine-guarding rules at 29 C.F.R. § 1910 Subpart O) do provide is evidence of the industry’s recognized standard of care, which is commonly introduced in a design-defect case even though it isn’t the legal basis for it.

Who Can Be a Defendant

Depending on the theory and your state’s law, potential defendants can include:

• The equipment manufacturer
• A distributor or retailer in the chain of sale
• A component-part manufacturer, where a specific part (rather than the whole machine) was defective
• A repair or maintenance contractor, where negligent servicing rather than the original design or manufacture caused the defect

Why Your Employer Usually Isn’t a Direct Defendant Here

In most states, workers’ compensation is the exclusive remedy against your employer for a workplace injury — meaning you generally cannot sue your employer directly for ordinary negligence, even where the employer’s own conduct contributed. This is precisely why the product liability claim is aimed at the equipment’s manufacturer rather than your employer: it is a route around that exclusivity rule, not through it. Narrow exceptions to employer exclusivity exist in some states (intentional conduct, in particular), but they are the exception, not the general rule.

A Deadline That Isn’t About When You Got Hurt

Workplace equipment is often old, and that matters here in a way it doesn’t for most personal injury claims. Beyond the ordinary statute of limitations — which runs from the injury, like any other claim — many states impose a separate statute of repose on product liability claims: an outer deadline measured from the date the product was sold or manufactured, regardless of when you were injured or when the defect was discovered. Commonly 10 to 12 years, this can bar a claim entirely against a machine that has been in service for over a decade, even though your injury just happened. Connecticut (Conn. Gen. Stat. § 52-577a) and Arizona (Ariz. Rev. Stat. § 12-551) set 10- and 12-year periods respectively; Florida and Illinois also use 12 years. Find out how old the equipment actually is early — it can determine whether the product liability claim exists at all, independent of how strong the defect evidence is.

The Subrogation Question

Your employer’s workers’ comp carrier has typically already paid your medical bills and a portion of lost wages by the time a product liability claim resolves — and most states allow that carrier to recover those payments out of your product liability settlement through subrogation, since you generally cannot recover the same economic losses twice. This is usually a negotiated reduction rather than a full dollar-for-dollar repayment, and an attorney handling the product liability claim typically negotiates it directly with the workers’ comp carrier.

What to Preserve Immediately

1. Do not discard, repair or modify the equipment — it is often the single most important piece of evidence, and its condition at the time of the incident matters enormously.
2. Photograph everything before any repair, cleanup or removal.
3. Identify the manufacturer, model and any safety guards or warning labels present or missing.
4. Preserve maintenance and inspection records for the specific unit.
5. Report the incident through your employer’s standard process to preserve your workers’ comp claim regardless of the product liability question.
