Emmett Foster and his wife appeal a judgment in favor of appellees Caterpillar Tractor Company (“Caterpillar”) and Gould, Inc. (“Gould”) following a jury trial. Because of the Michigan Supreme Court’s subsequent and specific rejection of language in an intermediate appellate court decision upon which the trial court relied, we are obliged to reverse and remand.
Owens v. Allis-Chalmers Corp.,
While in the course of his employment with Ministrelli Construction Company, appellant Foster attempted to jump start the battery of a Caterpillar 950 front-end loader. The battery exploded and severely injured Foster.
Foster and his wife brought this diversity suit in the District Court. Their complaint raised products liability claims alleging a design defect and failure to warn regarding the dangers of the battery. Gould manufactured and designed the battery in accordance with Caterpillar’s specifications. Michigan law applies.
Erie R.R. Co. v. Tompkins,
It was undisputed at trial that the explosion most likely occurred because an external spark created during the jump starting process ignited some hydrogen gas normally found over a battery. The ensuing flame apparently was able to enter the battery through its vent caps and ignited the battery’s internal gases.
An expert testifying for Gould stated that Gould was aware in 1974 or early 1975, when the battery was manufactured, that explosions could occur during the jump start procedure. He testified further that explosion-proof “flame arrestor” caps prevent external sparks from entering the battery, reducing the possibility of explosions. The Gould battery was equipped with conventional rather than explosion-proof caps.
The Fosters introduced proof that a 1969 patent for explosion-proof caps was similar in design to a cap patented in 1949. In fact, the product designed for Gould was refused a patent for such a vent cap in 1975 because the U.S. Patent Office did not view the design as novel. The Fosters also introduced proof that all 1974 General Motors automobiles produced in 1973 were equipped with Delco batteries which had explosion-proof caps. Gould was in the process of developing such caps before 1974 but did not produce them until 1976.
The Fosters’ counsel made an offer of proof that their expert would testify that explosion-proof caps were available at the time the Gould battery was manufactured and sold, and that they were a reasonable safety device to protect against explosions. The district judge refused to admit this evidence, finding that a jury issue is created regarding the reasonableness of a design only where it is shown that the product did not conform to governmentally imposed standards or to the generally prevailing practice in the industry. Adhering to this holding, the district judge granted a directed verdict in favor of Gould and Caterpillar and did not instruct the jury regarding the duty to install reasonably adequate safety devices. The jury was only allowed to consider the adequacy of the warnings regarding the dangers associated with the battery, and it returned a verdict for Gould and Caterpillar. 1 The Fosters filed a Motion for a New Trial, which was denied. This appeal followed.
The district judge in refusing to submit the issue of the reasonableness of safety devices to the jury relied primarily upon
Owens v. Allis-Chalmers,
the particular design was not in conformity with industry design standards, design guidelines established by an authoritative *656 voluntary association, or design criteria set by legislative or other governmental regulation....

The
Owens
case arguably was inconsistent with Michigan products liability law.
See, e.g., Marietta v. Cliff’s Ridge, Inc.,
This Court has previously held that compliance with governmental and industrial standards does not preclude a trier of fact from finding certain conduct to be negligent. The holding in Marietta v. Cliff’s Ridge, Inc.,385 Mich. 364 , 369-370,189 N.W.2d 208 (1971), cited with approval in Hill v. Husky Briquetting, Inc.,393 Mich. 136 ,223 N.W.2d 290 (1974), remains as precedent. Also see Webster v. Symes,109 Mich. 1 ,66 N.W. 580 (1896).
As stated in Marietta,385 Mich, at 369-70 ,189 N.W.2d 208 :
“The customary usage and practice of the industry is relevant evidence to be used in determining whether or not [the] standard [of reasonable care] has been met. Such usage cannot, however, be determinative of the standard.”
Judge Learned Hand eloquently stated the rule when he wrote:
“Indeed, in most cases reasonable prudence is in fact common prudence; but strictly it is never its measure; a whole calling may have unduly lagged in the adoption of new and available devices. It never may set its own tests, however persuasive be its usages.”
The T.J. Hooper,60 F.2d 737 , 740 (CA2, 1932).
We note that our Legislature has recently enacted a statute which provides that industrial and governmental standards are admissible in products liability actions, M.C.L. § 600.2946; M.S.A. § 27A.2946. The statute does not provide that such standards are conclusive. The defendant, in arguing that plaintiff did not present a prima facie case, does not challenge the rule that compliance with governmental and industrial standards is admissible as evidence but is not conclusive as to whether the defendant was negligent or the product was defective. We reaffirm that position.
(emphasis added). 2 The expert’s evidence regarding the reasonableness of the alternative design should therefore have been admitted.
The question then becomes whether a directed verdict was proper. We are, of course, bound by Michigan law in determining the sufficiency of the evidence.
Gold v. Nat’l Sav. Bank,
We recognize that Gould and Caterpillar introduced evidence which, if believed, tended to show that explosion-proof caps were not without risks. While the jury may properly consider such countervailing evidence regarding the practicality of alternate designs, the reasonableness of protective or preventative measures remains an issue to be decided by the jury after considering all of the evidence.
Elasser, supra,
Accordingly, the judgment entered by the district court is reversed and the cause is remanded for further proceedings consistent with this opinion.
Notes
. No appeal was taken regarding this theory of liability.
. After the Michigan Supreme Court released its decision in
Owens,
we requested supplemental briefing concerning its impact on the present case. The language cited above clearly contradicts Caterpillar’s assertion that the Michigan Supreme Court disagreed only with the lower court’s allocation of the burden of proof and not with its rationale.
