Facts

Uloth was injured while working on a Loadmaster Model LM 316 refuse body designed and manufactured by City Tank and Old Dominion. The machine's packer blade descended through a trash hopper and created a shear point at the loading sill; after Uloth activated the compaction cycle, he jumped onto the rear step, lost his balance, and his foot was caught and severed by the descending blade. Uloth had limited experience with the machine and had not previously operated the lever that activated the packer panel. Uloth introduced expert testimony that several known safety devices, including side steps, interlocking hopper doors, a stop bar, an interrupted cycle, or a dead-man control, were available and would have reduced the danger without significantly impairing performance.

Issue

Whether the trial judge erred in refusing to direct verdicts or enter judgments notwithstanding the verdicts for the defendants on the negligence claims. More specifically, the court considered whether a product that functions as intended, presents an obvious danger, or is accompanied by adequate warnings can still be negligently designed, and whether Uloth assumed the risk as a matter of law.

Rule

A designer has a duty to design machinery with reasonable care to eliminate avoidable dangers. In a design negligence case, the inquiry is not limited to whether the product functioned as intended; warnings and the obviousness of the danger are factors for the jury, not absolute bars to liability. A case for the jury exists if the plaintiff can show an available design modification that would reduce the risk without undue cost or interference with the machinery's performance.

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

In Toledo, Ohio, Mara Jensen lost two fingers while using a commercial dough mixer made by Lakefront Food Systems. The mixer operated exactly as designed, but its exposed pinch point could have been covered by a simple metal guard already used on similar machines without slowing production or materially increasing cost.

If Mara sues for negligent design, what is the strongest argument against the manufacturer's motion for a directed verdict?

Explanation. The majority rejected any rule that intended functioning defeats a negligent design claim. The focus is whether the product was designed with reasonable care to eliminate avoidable dangers. Evidence of an available guard that would reduce risk without undue cost or interference with performance is enough to create a jury question. (Derived from Uloth v. City Tank Corp. (n.d.).)
