Takeaway
In short, this case adopts Restatement § 402A in Ohio but holds that a manufacturer and sellers are not liable when an employer’s substantial post-sale safety modification, rather than any original product defect, causes the employee’s injury.
Mrs. Temple, an employee of Superior, was severely injured when a power punch press activated while her hands were in its danger zone. The press had been manufactured by Wean United and later sold by G.M. Superior altered the press’s original two-button activating arrangement after purchase: following its company policy, it lowered the buttons from shoulder height to waist height, positioned them facing upward and 24 inches apart, and used the press to stamp stock long enough to bridge the gap between the buttons. Superior had ordered and installed the operating buttons manufactured by Square D.
The Temples sued Wean, G.M., and Square D on theories of negligence, implied warranty, and strict liability in tort. They contended that the press was unreasonably dangerous because it lacked adequate warnings and a fixed barrier guard, and that the button assembly should have included or warned about horseshoe-shaped guards. The trial court granted protective orders and summary judgment for the defendants, and the Court of Appeals affirmed. The Ohio Supreme Court affirmed as well.
Issue #1
Whether Ohio should adopt Restatement (Second) of Torts § 402A as the formulation of strict products liability in tort.
Holding
Yes. The Court approved § 402A because it substantially matched Ohio’s existing implied-warranty-in-tort doctrine and provided a useful framework for analyzing product-defect claims.
Reasoning
Ohio had already moved beyond contract-based warranty concepts in Lonzrick v. Republic Steel Corp. and recognized strict liability in tort for defective products. Under Ohio precedent, a plaintiff had to prove a defect, that the defect existed when the product left the defendant’s hands, and that the defect proximately caused the injury.
Section 402A was consistent with that established Ohio approach. Its requirement that a seller supply a product in a defective condition unreasonably dangerous to the user, and that the product reach the user without substantial change, gave the Court a clearer and more fully developed analytical structure without materially changing Ohio law.
Issue #2
Whether Wean and G.M. were strictly liable for Mrs. Temple’s injury when Superior altered the press’s activating-button arrangement after purchase.
Holding
No. Superior’s alteration was a substantial change, and the undisputed evidence showed that the press had no original defect; Superior’s alteration and use of the press were the sole responsible cause of the injury.
Reasoning
Strict liability under both Ohio law and § 402A requires proof that the claimed defect existed when the product left the seller’s control. Section 402A also applies only when the product reaches the user without a substantial change in its condition.
Superior changed the original method of guarding by lowering and repositioning the activating buttons. That alteration materially increased the risk of unintentional activation, especially when Superior used stock long enough to bridge the 24-inch space between the buttons. The Court therefore treated the change as substantial as a matter of law.
Because the press was not defective when it left Wean’s hands and because the later alteration created the hazard, neither Wean as manufacturer nor G.M. as subsequent vendor could be strictly liable. Cases involving employers’ later modifications of power presses supported the same conclusion.
Issue #3
Whether Square D, as the manufacturer of the buttons installed by Superior, had a strict-liability duty to warn that the button assembly required protective guards.
Holding
No. Square D had no duty to anticipate the particular way Superior would integrate otherwise nondefective components into its press, and a warning would have added nothing because Superior already knew protective guards were available.
Reasoning
The buttons were component parts ordered and installed by Superior, not a completed press assembly designed and sold by Square D. The duty to warn did not require Square D to speculate about every potentially dangerous configuration that another company might create by incorporating ordinary components into a larger machine.
Although Square D made horseshoe-shaped button guards, Superior’s engineer testified that Superior had known for years that those guards were available and would prevent accidental button depression. Requiring Square D to warn Superior of a safety measure Superior already knew about would have been futile.
Issue #4
Whether the defendants were negligent for failing to warn of the press’s dangerous condition.
Holding
No. The defendants could not be negligent for failing to warn of a danger created only by Superior’s post-sale alteration, of which they neither knew nor reasonably could have known.
Reasoning
A failure-to-warn claim is grounded in negligence because it concerns whether a manufacturer or seller met a duty of reasonable care. Under Ohio law, that duty ordinarily arises when the defendant knows of a latent defect that makes the product unsafe and fails to warn of it.
Here, the allegedly dangerous condition did not exist when the press was manufactured or sold. It resulted from Superior’s later modification of the button arrangement and its operational practices, so the defendants had no knowledge, and no basis to have knowledge, of the condition requiring a warning.
Issue #5
Whether Wean negligently designed the press by failing to provide a fixed barrier guard that would keep an operator’s hands out of the danger zone.
Holding
No. As a matter of law, Wean was not negligent because the applicable Industrial Commission safety regulation recognized a two-hand tripping device, which the press had, as an acceptable alternative to a fixed barrier guard.
Reasoning
A manufacturer must use reasonable care to make its product safe for its intended use, but it is not required to make the product accident-proof or foolproof. The Court looked to the governing workplace-safety regulation to evaluate the reasonableness of Wean’s design choice.
Industrial Commission Safety Code IC-5-08.03 required power presses to be constructed or guarded to prevent an operator’s hands from entering the danger zone, but it expressly listed both fixed barrier guards and two-hand tripping devices as acceptable methods. Because this press was equipped with a two-hand tripping device, Wean’s decision not to supply a fixed barrier guard was not negligent as a matter of law.
Issue #6
Whether summary judgment and the protective orders were properly granted for the defendants.
Holding
Yes. The record showed no genuine issue of material fact, and any error in granting the protective orders caused no prejudice because the defendants were entitled to judgment as a matter of law on the existing evidence.
Reasoning
Under Ohio Civil Rule 56(C), summary judgment is proper when no genuine issue of material fact remains, the movant is entitled to judgment as a matter of law, and reasonable minds could reach only a conclusion adverse to the nonmoving party when the evidence is viewed in that party’s favor.
Depositions of Superior’s president, chief engineer, and press-room foreman established that Superior’s alteration of the safeguarding arrangement and its use of the press caused Mrs. Temple’s injury. That testimony eliminated any material factual dispute concerning the defendants’ responsibility.
The Court found no prejudice from the protective orders because the testimony already in the record independently established the dispositive facts. Additional discovery therefore could not change the legal conclusion that the defendants were entitled to judgment.
