This divеrsity case was brought by the administratrix of the estate of Robert Burton for damages resulting from an accident that caused Burton’s death. The original defendant was the Osborn Manufacturing Cоmpany, but the plaintiff later added two counts directed solely against the appellee, L. 0. Smith *110 Foundry Products (“Smith”). The two added counts were based on breach of warranty and striсt liability in tort; plaintiff acknowledges the two to be equivalent under Indiana law. The District Court granted summary judgment in favor of Smith on both counts, and made the direction and determination necessary to appealability under Fed.R. Civ.P. 54(b). We affirm.
The following facts are undisputed:
Burton was employed at the Indianapolis, Indiana plant of International Harvester Company, where he had worked sincе 1955. The accident occurred while he was participating in the repair of a molding machine, which forms molds by applying sand to metal patterns. In the operation of thе machine a “parting” compound, consisting of a highly flammable liquid, is dispensed under pressure by the machine for the purpose of preventing the sand from sticking to the metal pаtterns.
During the repairs, another employee attempted to cut through a bolt on the machine with an acetylene torch. The flame severed a hose containing thе pressurized parting compound, which escaped and ignited, causing fatal burns to Burton, who was standing nearby.
Smith had no part in the design or construction of the machine, which was manufactured by the defendant Osborn Manufacturing Company. Smith did, however, supply the parting concentrate which was the active ingredient of the parting compound. The concеntrate contained a small amount of kerosene, but additional kerosene was needed to thin the material so it could be sprayed evenly on the metal patterns. Accordingly, International Harvester, pursuant to Smith’s recommendation, mixed the concentrate with an equal part of kerosene to form the parting compound.
Adding kerosеne increased volatility. Vapor from the parting concentrate, before it was mixed with kerosene, would ignite at 305 °F. After the kerosene was added, vapor from the mixture would ignite at 190 °F.
International Harvester had used Smith’s product or a closely related product for some 30 years. Before the accident, Smith had never warned Harvester or its employees of the volatile nature of the product, nor had Smith recommended the use of the less flammable or “non-flammable” substitutes that were available. After the aсcident Harvester changed to a less volatile parting agent at Smith’s suggestion and also posted signs identifying the hose carrying the parting agent and warned maintenance pеrsonnel of the danger of rupturing the hose.
The District Court found that it was common knowledge among the maintenance employees, including Burton, that a flammable liquid was used in the molding mаchine. Plaintiff contends there is a genuine issue as to whether such knowledge existed, but we need not consider this contention because, as we understand Indiana law, that issue is irrelevant.
The District Court based its summary judgment on several alternate grounds, including lack of defect, misuse, assumption of risk, and proximate cause. We find the first ground determinative.
The doctrinе of strict liability, as set forth in section 402A of the
Restatement of Torts (Second)
has been adopted as the law in Indiana.
Ayr-Way Stores, Inc. v. Chitwood,
Ind.,
At leаst three types of unreasonably dangerous defects may exist under section 402A. A product may be defective because of manufacturing flaws, defective design, or failure to supply complete information about the product’s dangers. Keeton,
Products Liability,
We consider first Smith’s failure to warn. Under Indiana law, “it is well established that a product, although virtually faultless in design, material, and workmanship, may nevertheless be deemed defеctive . . . where the manufacturer fails to discharge a duty to warn or instruct with respect to potential dangers in the use of the product”
Nissen Trampoline Co. v. Terre Haute First National Bank,
Ind.App.,
A duty to warn exists only when those to whom the warning would go сan reasonably be assumed to be ignorant of the facts which a warning would communicate. If it is unreasonable to assume they are ignorant of those facts, there is no duty to wаrn. As an Indiana court said in
Nissen Trampoline Co. v. Terre Haute First National Bank, supra,
Ind.App.,
The crucial fact in the case at bar, in our view, is that Smith’s product was mixed before use with an equal amount of kerosene. Because it can reasonably be expected that any user of kerosene will know it is flammable, neither Smith nor the supplier of the kеrosene had any duty to warn of that fact. For the same reason, Smith had no duty to warn users that its product did not have the effect of rendering kerosene flame-proof; no one would have reasonably expected the product to have that effect.
Of course, an “obviously dangerous” product is nonetheless dangerous, especially to employees who are unaware that they are working in proximity to it. But it was not the duty of Smith to remind International Harvester of this fact, or of the obvious precautions to bе taken. Smith’s duty was only to make known, to those International Harvester employees to whom it had access, properties of its product that were dangerous *112 but nonobvious. It did not breach that duty.
For related reasons, the parting concentrate was not defectively designed, even though less flammable substitutes were available. Under Indiana law, a product is not defectivеly designed where its dangerous properties are patent.
Schemel v. General Motors Corp.,
Although we have considered separately the plaintiff’s two theories— failure to warn and defective design— both thеories suffer from the same fundamental flaw. While defects can take various forms under section 402A, the basic test is failure to meet the reasonable expectations of the ordinary user as to safety. See
