In this product liability action, plaintiff Skip Wright, a firefighter employed by the City of Glendale, was injured when a “deck gun” or water cannon mounted on a firetruck broke loose while under pressure from the water pump, throwing Wright in the air and onto the ground with the deck gun landing on him. Plaintiffs appeal from summary judgment granted in favor of defendants, collectively referred to herein as Stang, the alleged successors of the corporation which manufactured the deck gun. The issues on appeal are whether the trial court correctly determined that “There is no evidence provided that the deck gun was defective. The piece of pipe that disengaged was not part of the deck gun and was requested and installed by another party. . . . [Tjhere is no duty to warn regarding a 17 year old component part that was not defective.”
Factual and Procedural Background
On November 14, 1994, plaintiff Skip Wright filed a complaint against Stang, among others, for negligence, strict liability, and breach of warranties; plaintiff Debbie Wright asserted a claim for loss of consortium. The complaint alleged that while Skip Wright was in the course and scope of his employment as a firefighter for the City of Glendale on November 15, 1993, he was using a Stang Manufacturing Company deck gun attached to a Seagrave fire engine; the deck gun broke loose and failed while under pressure, throwing him into the air and onto the ground, with the deck gun landing on him.
The most comprehensive evidence in our record setting out the details of the accident is provided by the declaration of Ralph Craven (Craven), plaintiffs’ expert consultant who is a fire apparatus expert and president of the National Institute of Emergency Vehicle Safety; Craven inspected the fire engine involved in the incident herein, including the deck gun and the riser to which it was attached; he also viewed a videotape of the incident that resulted in plaintiff’s injuries. According to Craven, water was being supplied to the deck gun from a water tank on the fire truck; when the water supply was exhausted, a hydrant connection was made and the engineer on the fire truck activated a valve that allowed the water to flow through the pump directly to the deck gun; the pump revolutions were high and the water pressure generated a nozzle reaction, known in the industry as a “water hammer.” A water hammer occurs when water is rapidly turned on and off, causing force to be generated which is more than four to six times the applied force; a nozzle reaction occurs, which, in turn, causes reactionary forces on the attachments, including the riser, to which the deck gun was attached with a three-inch threaded riser pipe. In this case, the threaded riser
The deck gun apparently was manufactured in 1977 by Stang Hydronics; the successor to Stang Hydronics is defendant Stang Enterprises, Inc. For purposes of the summary judgment motion, and this appeal, the Stang defendants provided no evidence to explain the nature of their relationship to Stang Hydronics and they did not provide sufficient evidence to negate the assertion that they are liable as successors to the manufacturer of the deck gun under principles set out in
Ray
v.
Alad Corp.
(1977)
In support of their motion for summary judgment, defendants asserted, and plaintiffs agreed, that the following facts were undisputed: The three-inch riser pipe remained attached to the deck gun at the time of plaintiff’s accident, and the threaded pipe did not shear at its connection with the deck gun; the steel which comprises the deck gun did not fail; according to blue prints, a flange mount system was available and could have been utilized by the City of Glendale. Defendants supported their motion with the declaration of Duane Bergmann, a licensed mechanical engineer, who stated that he inspected the deck gun and riser pipe; the pipe did not fail at the connection point with the deck gun; it was his opinion that the threaded mounting area of the deck gun was adequate; the threaded mounting of the deck gun did not fail, and the material which comprises the deck gun did not fail.
Defendants also asserted that they did not manufacture the deck gun, and had no involvement with it, but plaintiffs disputed those assertions on the ground that the evidence did not establish the relationships among the various defendants, or defendants’ relationships with the manufacturer of the deck gun. Thus, plaintiffs maintained that even if it were undisputed that defendants did not manufacture or distribute the deck gun, that fact alone would not entitle them to summary judgment. (See fn. 1, ante.)
In opposition to the motion, plaintiffs argued (1) that the fact that the deck gun itself did not fail does not preclude a finding that it was defective based on the lack of sufficient warnings about the proper maintenance of the gun, its attachments, and proper mounting; and (2) a component part manufacturer may be held liable for a failure to warn under the instant circumstances.
2
Plaintiffs’ opposition was supported with the declaration of Craven, who
Craven further declared that he was of the opinion “that Stang, as the manufacturer and seller of the deck gun, had a duty to warn the user of the deck gun regarding the potential hazards of a water hammer and the nozzle reaction that occurs as a result thereof, which warning must necessarily include a reference to the need for proper inspection and maintenance of the deck gun, including periodic inspection for the presence of corrosion, proper threading of attachments, and use of a flange mounting system or attachments made of industrial heavy steel or other materials that resist corrosion. In this regard, it is foreseeable to anyone familiar with fire apparatus that
Craven also concluded that because Stang did not design the deck gun with a flange mounting system, Stang as manufacturer had a duty to inform the installer and user of the deck gun that it must be installed in such a manner to safely handle the forces that would be generated during normal and foreseeable use, including those of water hammers; in this regard, it is the fire department that would necessarily be responsible for maintenance of the deck gun and attachments. In addition, Craven opined, the correct riser pipe was not used, nor was the riser installed with adequate thread depth to provide adequate strength. In this case, steel or galvanized steel pipe was used rather than industrial heavy weight steel, which has twice the thickness of typical steel or galvanized steel; in addition, when steel or galvanized steel pipe is used, the amount of the base material is reduced dramatically during the thread-cutting process, resulting in a loss of strength in the pipe and its ability to resist corrosion over time. Thus, Craven was of the opinion that the failure to use the correct pipe and the lack of adequate thread depth on the riser, “when subjected to the water hammer nozzle reaction caused the separation of the riser.”
Relying upon Craven’s declaration, plaintiffs asserted that the following nine material facts relating to product defect and causation were in dispute:
After hearing on the summary judgment motion, the court issued an order granting the motion. The order stated in pertinent part: “[T]he moving [parties are] entitled to summary judgment as a matter of law for the following reasons. There is no triable issue of fact regarding whether or not the deck gun is defective. There is no evidence provided that the deck gun was defective. The piece of pipe that disengaged was not part of the deck gun and was requested and installed by another party. The court finds that there is no duty to warn regarding a 17 year old component part that was not defective. The court further finds that the plaintiffs’ expert declaration did not provide sufficient evidence to overcome the holding in
Union Bank
v.
Superior Court
(1995)
Plaintiffs filed timely notice of appeal from the judgment.
Summary Judgment Principles
“ ‘Summary judgment is appropriate only if the evidence shows there is no triable issue of any material fact, and that the moving party is entitled to judgment as a matter of law. The trial court’s obligation in ruling on a summary judgment motion is to determine whether issues of fact exist, not to decide the merits of the issues themselves. When making that determination, the trial court must strictly construe the affidavits of the moving party, and liberally construe those of the dpponent. . . .’ [Citation.] [¶] . . . We independently review the record to determine whether the moving party is entitled to judgment as a matter of law.”
(Schwoerer
v.
Union Oil Co.
(1993)
In the instant case, the cause of action for strict products liability alleges that the deck gun was “defectively designed, manufactured, assembled, labeled, distributed, advertised, marketed, sold, inspected, tested, or maintained.” Thus, the pleading is broad enough to allege all three theories of product defect. There are commonly three types of product defects. “First, there may be a flaw in the manufacturing process, resulting in a product that differs from the manufacturer’s intended result. . . . [<J0 Second, there are products which are ‘perfectly’ manufactured but are unsafe because of the absence of a safety device, i.e., a defect in design. . . . [U The third type of defect. . . is a product that is dangerous because it lacks adequate warnings or instructions.”
(Brown
v.
Superior Court
(1988)
Respondents argue that because the deck gun did not “fail,”— which we interpret to mean that it did not break, or suffer any damage, during Skip Wright’s accident—it was not a defective product within the meaning of strict products liability law. Appellants agreed it was undisputed that the deck gun did not “fail,” and that the pipe remained attached to the gun during the accident, and the pipe did not shear at the point it was connected with the deck gun. However, respondents cite no authority for their implied proposition that when a product causes personal injuries it is not defective merely because the product itself remains intact or is not damaged in an accident. Further, no explanation or evidence was offered by respondents to link the fact that the deck gun itself did not break with the alleged theories of design defect and “warning defects,” which appear to be the product defects upon which appellants are basing their action.
One of the theories of liability suggested by appellants, and supported by Craven’s declaration, is that the deck gun was defective in design because it was not designed with a flange mounting system. Appellants in their opening brief appear to concede the fact that the deck gun was manufactured in accordance with the requests of the Glendale Fire Department, although there was no evidence on the issue either way offered by the parties below. We thus cannot determine whether the deck gun in question was mass produced, or a special piece of equipment made in accordance with the purchaser’s plans. In any event, the uniqueness of a purchaser’s order does not alter the manufacturer’s responsibilities and is not a defense. (See
DeLeon

Commercial Manufacturing & Supply Co.

Product Defect Based on Inadequate Warnings or Instructions 4
Under ‘warning defect’ strict liability, a product, even though faultlessly made, is defective if it is ‘unreasonably dangerous to place ... in the hands of a user without a suitable warning and the product is supplied and no warning is given.’ [Citation.] It is now settled that ‘knowledge or knowability [of the danger] is a component of strict liability for failure to warn.’
(Anderson
v.
Owens-Corning Fiberglas Corp.
(1991)
“Negligence law in a failure-to-wam case requires a plaintiff to prove that a manufacturer or distributor did not warn of a particular risk for reasons which fell below the acceptable standard of care, i.e., what a reasonably prudent manufacturer would have known and warned about. Strict liability is not concerned with the standard of due care or the reasonableness of a manufacturer’s conduct. The rules of strict liability require a plaintiff to prove only that the defendant did not adequately warn of a particular risk that was known or knowable in light of the generally recognized and prevailing best scientific and medical knowledge available at the time of manufacture and distribution. Thus, in strict liability, as opposed to
In this case, Stang did not claim below, nor do they contend on appeal, that a “water hammer,” nozzle reaction, and corrosion are unknown or unknowable risks associated with the use of a deck gun. Therefore, “Whether a warning is adequate depends on several factors, among them ‘the normal expectations of the consumer as to how a product will perform, degrees of simplicity or complication in its operation or use, the nature and magnitude of the danger to which the user is exposed, the likelihood of injury, and the feasibility and beneficial effect of including a warning.’ ”
(Schwoerer
v.
Union Oil Co., supra,
Respondents argue that “The duty to warn does not include the duty to warn of known dangers foreseeable to the user.” They claim that Craven’s declaration establishes that it is foreseeable to anyone familiar with fire apparatus, including Skip Wright, allegedly a firefighter for 13 years, that water hammer nozzle reactions can occur and that this, in combination with corrosion, can result in the failure of attachments to the deck gun. Respondents fail to cite any evidence that Wright was aware of any of the dangers of separation due to the design features of the deck gun and attachments as noted by Craven. Although Wright may have been aware of the water hammer effect in general, there is no evidence that he was aware that he was using a product which had the problems or defects noted by Craven, or that he may have been subjecting himself to the risk of injury in using the deck gun with the riser pipe attachment.

(1993)
In examining the two elements of the test for application of primary assumption of the risk—the nature of the activity in which defendant is engaged, and the relationship between the defendant and the plaintiff to that activity—the court in
Milwaukee Electric Tool Corp.
stated as to the first factor: “We find nothing in the nature of the manufacturing activity to indicate that a finding of no duty on the manufacturer’s part should be made. To the contrary, we believe there is a sound basis in the development of strict products liability doctrine to support analysis of a products liability case, even one involving an assertion of assumption of the risk, in terms of a duty on the part of the manufacturer to produce defect-free products.” (
“According to
[Knight
v.
Jewett, supra,
We find Milwaukee Electric Tool Corp. persuasive here, and conclude that respondents failed to establish primary assumption of the risk as a bar to appellants’ cause of action for strict products liability. Accordingly, the trial court erred in finding there was “no duty to warn regarding a 17 year old component part. . . .” 5 Further, assuming without deciding that the case is subject to comparative fault principles, summary judgment still would have been inappropriate. Inasmuch as respondents have failed to establish that primary assumption of the risk bars appellants’ claim for strict products liability, we proceed to address respondents’ contention that as a component part manufacturer it is not liable for a failure to warn when the final product is subsequently packaged, labeled and marketed by another manufacturer.
To support their claim that they are not liable as component part manufacturers, respondents rely upon
Walker
v.
Stauffer Chemical Corp.
(1971)
Unlike the situation in Walker, there is no evidence in this case that the deck gun was not intended to reach the ultimate consumer in the same condition as it left the manufacturer. Walker is not dispositive here.
We also conclude that Lee is not dispositive in the instant case. In Lee, the defendant manufactured a component part, a motor, which was installed in a meat grinding machine which injured plaintiff; plaintiffs claimed that the motor was defective because it lacked a warning that it did not stop immediately when turned off. The court upheld summary judgment in favor of defendant, stating that “. . . there is nothing to indicate that the motor in its use had unreasonably dangerous propensities not ordinarily discoverable by the user. The uncontradicted evidence shows that all motors, even ‘brake motors,’ do not stop immediately. There is no danger in the motor which would not have been obvious to a person of ordinary intelligence. [00 Moreover, we stress that defendant gave no input and had no control over the design, manufacture, and packaging of the finished product. The cases relied on by defendant demonstrate a reluctance against imposing liability for the component-part manufacturer’s failure to warn the consumer where the final product is subsequently packaged, labeled and marketed by another manufacturer. [Citations.] [00 • • • [00 Accordingly, we conclude that defendant owed no duty to plaintiffs to warn that the motor did not stop immediately.” (169 Cal.App.3d at pp. 388-389, fn. omitted.)
In light of
Knight
v.
Jewett
and
Milwaukee Electric Tool Corp.,
discussed above, we question
Lee's
analysis of the “duty” issue for purposes of determining liability under strict products liability principles. We also fail to see how the deck gun was “packaged, labeled, and marketed,” by the Glendale Fire Department; rather, the fire department apparently installed it on their firetruck without making any changes to the deck gun or firetruck. It is also
not negated
on our record that the manufacturer knew that the fire
We find the circumstances in the instant case more similar to those in
Huynh
v.
Ingersoll-Rand
(1993)
“ ‘Misuse’ is a defense only when that misuse is the actual cause of the plaintiff’s injury, not when some other defect produces the harm.”
(Huynh
v.
Ingersoll-Rand, supra,
The court in
Huynh
went on to state that “A manufacturer does not satisfy its duty to warn by supplying a warning so vague and ambiguous only some users are likely to read and comprehend the danger. It cannot count on the sophisticated users—even those in an employment setting—passing on to the less sophisticated the fact the obtuse language the manufacturer included
As in Huyhn, we conclude that respondents failed to counter Craven’s declaration, or to otherwise negate appellants’ allegations that the manufacturer of the deck gun did not provide an adequate, or any, warning against the potential dangerous and foreseeable “mismatch” of the deck gun and riser pipe attachments which did not have adequate strength or design to withstand the water pressures generated with the use of the deck gun, and the alleged foreseeable danger that the deck gun or its attachments may become separated from the fire truck under such pressures. We thus conclude that triable issues of fact exist on the “warning defect” aspect of strict products liability.
Finally, we note that since the summary judgment motion admittedly did not address or negate successor liability under
Alad,
the motion should have been denied, whether or not any showing was made as to liability based on respondents’ own conduct or involvement with the manufacture or distribution of the deck gun. Thus, respondents’ citation to
Gee
v.
Tenneco, Inc.
(9th Cir. 1980)
Disposition
The judgment is reversed, and on remand, the trial court is directed to deny respondents’ motion for summary judgment. Appellants are entitled to costs on appeal.
Johnson, J., and Woods, J., concurred.
Respondents’ petition for review by the Supreme Court was denied August 13, 1997.
Respondents incorrectly contend that there is no evidence in the record that there were no warnings, and that the “warning defect” issue is not properly before us because appellants failed to establish the product lacked a warning. Inasmuch as Stang were the parties moving for summary judgment, they had the burden to negate all theories of liability reflected in the complaint. If there were indeed warnings or instructions given with respect to the deck gun, it was up to Stang to provide evidence of such. They did not do so. On the other hand, Craven’s declaration provides evidence that “Stang did not provide any of the aforementioned warnings [regarding the potential hazards of a water hammer and nozzle reaction, the need for proper inspection and maintenance, and the use of a flange mounting system or attachments made of industrial heavy steel].”
Thus, there is indeed evidence in our record that Stang did not provide the foregoing warnings with respect to the deck gun.
Notes
Robert Green, the president of defendant GST Industries, Inc., presented a declaration stating that in 1989 he purchased a portion of Stang Hydronics from Stang Enterprises, the successor to Stang Hydronics, Inc. The former corporate name of GST Industries, Inc., was Stang Manufacturing, Inc. According to the caption of defendants’ pleadings, Stang Manufacturing Co. is a division of Stang Hydronics, Inc.
In light of the issues raised below, and the state of the record, we need not further address the issue of the relationship of the Stang defendants to the manufacturer of the deck gun, Stang Hydronics. According to plaintiffs’ opposition to the summary judgment motion, defendants had previously moved for summary judgment on the ground that they were not successors to the corporation that manufactured the deck gun. We infer that such previous motion was denied or was ultimately unsuccessful. As acknowledged by plaintiffs, in the instant motion for summary judgment before us on this appeal, defendants do not attempt to negate successor liability under principles set out in
Ray
v.
Alad Corp., supra,
Accordingly, even if defendants did not themselves manufacture, design, or sell, etc., the deck gun in this case, they may be liable for injuries caused by a defective product and thus stand in the shoes of the manufacturer, Stang Hydronics, for purposes of imposing liability based on the theory of strict product liability. The
Alad
case thus offers an additional basis for imposition of strict products liability against defendants, in addition to any independent ground based on defendants’ own conduct or involvement in the manufacture and distribution of the deck gun. Because of the multiple theories of liability asserted against defendants,
Defendants below, and on appeal, make a great deal out of the fact that plaintiffs responded “Undisputed” to the following separate statement of fact (No. 7 in defendants’ papers, but numbered 8 by plaintiffs, who mixed up the numbers of defendants’ separate
It is clear from plaintiffs’ opposition that plaintiffs were not conceding the issues of product defect or causation, although plaintiffs admitted the facts that the riser pipe broke and there was no damage to the deck gun itself. Defendants below and in their brief on appeal, fail to establish that plaintiffs’ response to their separate statement of undisputed facts is accorded the same effect as a judicial admission in a pleading. As noted by the court in
Kirby
v.
Albert D. Seeno Construction Co.
(1992)
In light of Kirby, it is clear that plaintiffs made a mistake in responding “Undisputed” to that portion of defendants’ separate statement that it was undisputed that the deck gun did not cause plaintiff’s injuries. Such an assertion contradicts other portions of plaintiffs’ response to the separate statement, as well as plaintiffs’ own list of nine material facts which they claimed were in dispute, and which they supported with Craven’s declaration. Moreover, we fail to see how defendants can rely on the mistaken response to bolster their motion when the response to the separate statement is not evidence because it is not under oath, nor is it verified. Accordingly, we do not consider the mistaken response of plaintiffs as a “judicial admission” or concession on the issues of liability and causation.
The trial court’s reference to the
Union Bank case
is puzzling, inasmuch as that case simply held that the 1992 and 1993 amendments to the summary judgment law intended to abrogate a Court of Appeal decision prohibiting moving defendants from securing a summary judgment based upon factually inadequate discovery responses of a plaintiff, and that the defendant therein was entitled to summary judgment on a fraud claim because “plaintiffs’ interrogatory responses demonstrate they have no evidence defendant made any fraudulent representations; plaintiffs’ interrogatory responses indicate they have no evidence defendant was a member of a fraudulent conspiracy; and plaintiffs admitted defendant had done nothing wrong in connection with the actual lending of the money . . . .”
(Union Bank
v.
Superior Court
(1995)
To the extent the court was referring to the plaintiffs’ apparently mistaken response of “undisputed” to a portion of one of defendants’ separate statements of fact dealing with the issue of causation, we conclude that no authority is provided in Union Bank which would allow such an ambiguous and mistaken response to be interpreted to be a “judicial admission” or an admission, when such response was not under oath or part of any pleading, and when the response was inconsistent with other responses and evidence submitted in opposition to the summary judgment motion. (See fn. 2, ante.)
In this aspect of its order, the court appears to confuse the theory of successor liability under
