Facts

Luis Liriano, a 17-year-old grocery store employee, was injured while feeding meat into a commercial meat grinder after its safety guard had been removed; his hand and lower forearm were amputated. Hobart manufactured and sold the grinder in 1961 with an affixed safety guard, but did not place warnings on the machine indicating that operating it without the guard was dangerous. Before the accident, Hobart knew that a significant number of purchasers had removed the safety guards and in 1962 began issuing warnings concerning guard removal. It was undisputed that the guard was intact when Super acquired the grinder, that Super removed it while the grinder was in its possession, and that Hobart knew such removals were occurring and were highly dangerous.

Issue

Whether a plaintiff whose design defect claim is barred by the substantial modification defense may nevertheless maintain a failure-to-warn claim based on the manufacturer's failure to warn of the dangers of such modification. Also, whether that claim was barred as a matter of law on these facts, though the court declined to answer that second question.

Rule

A manufacturer has a duty to warn against latent dangers resulting from foreseeable uses of its product of which it knew or should have known, and also against dangers from unintended uses that are reasonably foreseeable. That duty can extend to warning against foreseeable product modifications or misuse, even where the substantial modification defense would bar design defect liability. No duty to warn exists where the danger is patently open and obvious or where the user already appreciated the specific hazard to the same extent a warning would have provided; in close cases, those questions are generally for the jury.

One of 10 multiple-choice questions for this case. Pick an answer to see why.

Prairie Mill Equipment sold a commercial dough mixer in Toledo, Ohio with a metal interlock cover over the rotating blades. Years later, after learning that many bakery owners were removing the cover to speed production, Prairie Mill did not add any label warning against operating the mixer without the cover. A new employee at Lakefront Bakes was injured after his supervisor had removed the cover months earlier.

If the employee's design defect claim is barred because the product was substantially modified after sale, what is the strongest argument for allowing his failure-to-warn claim to proceed?

Explanation. The majority held that the substantial modification defense that defeats a design defect claim does not necessarily defeat a failure-to-warn claim. The manufacturer may still have a duty to warn of foreseeable dangerous modifications because warning analysis focuses on foreseeability and the adequacy and feasibility of warnings, not on redesigning the product to prevent all later alterations.
