*1042 OPINION
This is a civil action in which a Superior Court jury awarded damages to the plaintiff, Catherine Seittarelli, for personal injuries sustained when the oven door in her kitchen stove flew open, struck her, and tossed her to the floor. The plaintiff filed suit against the Providence Gas Company in 1961. In 1977, the defendant moved for dismissal of the complaint for lack of prosecution, and the plaintiff responded with a motion to assign the case under an amended complaint to the continuous jury trial calendar. The Superior Court denied the defendant’s motion and granted the plaintiff’s. 1
The plaintiff’s amended complaint in six counts alleged that the retailer of the stove, defendant Providence Gas Company, had committed specific acts of negligence, was negligent under the doctrine of res ipsa loquitur, had breached аn express warranty and implied warranties of merchantability and fitness for a particular purpose, and should be held strictly liable. The Providence Gas Company then filed a third-party complaint against the manufacturer of the stove, Hardwick Stove Company, seeking indemnity or contribution for any damage award resulting from the principal action. At the close of plaintiff’s case, the Providence Gas Company moved for a directed verdict upon all counts of plaintiff’s complaint. The trial justice granted the motion as to counts 4, 5, and 6, premised upon express warranty, strict liability, and res ipsa loquitur, respectively, but denied the motion as to counts 1, 2, and 3, grounded upon negligence and implied warranties of fitness and merchantability.
At the close of all the evidence when all parties rested, defеndant renewed its motion for a directed verdict on counts 1, 2, and 3. The defendant Hardwick moved for direction on the third-party complaint. The trial justice reserved decision on defendants’ motions and submitted the case to the jury. The jury returned a verdict for plaintiff against defendant Providence Gas Company in the sum of $14,000 and a verdict for Hardwick as to the third-party complaint. Following the jury verdict the trial justiсe reconsidered defendant Providence Gas Company’s motion for a directed verdict and Hardwick’s motion for a directed verdict, whereupon he denied defendant Providence Gas Company’s motion and granted Hardwick’s motion. The gas company moved for a new trial; the motion was denied.
The defendant Providence Gas Company appeals from the trial justice’s denial of its mоtion for a directed verdict against plaintiff on the negligence and implied warranty counts and the trial justice’s grant of Hard-wick’s motion on the third-party complaint. The plaintiff conditionally appeals the direction of verdicts for defendant on two counts, 2 one premised on a theory of res ipsa loquitur and the other founded on strict liability, in the event we sustain defendant’s appeal. Because we conclude that the trial court should have directed *1043 verdicts for defendant on all counts, we need not discuss defendant’s appeal in the third-party action.
The facts briefly summarized are as follows. In the autumn of 1959, plaintiff, then sixty-six years old, purchased from defendant a stove manufactured by the Hardwick Stove Company. On November 2, 1959, agents of defendant transported and installed the stove in plaintiff’s kitchen. The next day plaintiff set the temperature control of the oven at 350 degrees and placed a roasting chicken in a Pyrex dish inside the oven. Sometime thereafter plaintiff noticed that the glass window in the oven door had fogged. As she approached the stove she heard and saw the glass crack. The oven door opened and struck plaintiff just above the waist pushing her over backwards onto the kitchen floor.
The рlaintiff’s son telephoned the Providence Gas Company to notify it of what had occurred. Gas company servicemen, the day after the accident, replaced the oven door with a windowless door, inspected and tested the stove, and found it fully operational.
In the fall plaintiff sustained injuries to her back for which she was treated over several months. Although plaintiff had a prior history оf back problems, she testified that her movement was more restricted after the accident.

We note that a record containing the trial justice’s reasons for his decision on the motions for directed verdicts is not available to us. Nevertheless, settled Rhode Island law requires the trial justice to view the evidence in a light most favorable to the plaintiff, drawing every reasonable inferencе therefrom on his behalf, and to deny the motion for a directed verdict if he discerns triable issues upon which reasonable minds may differ. On review we place ourselves in the identical posture of the trial justice; we examine the evidence in the same manner and are bound by the same rules.
Geremia v. Benny’s, Inc.,
R.I.,
To avoid a directed verdict for defendant on the
res ipsa
and specific-negligence counts, therefore, plaintiff must have established a
prima facie
case of negligence.
Marshall v. Tomaselli,
Prom our reading of the transcript we conclude that plaintiff did not set forth, by evidence of either customary practices in the industry or past practices of defendant, an actual standard of care by which defendant should have abided, nor did she hypothesize by expert testimony an industrywide standard of care. Nevertheless, it generally can be presumed that de
*1044
fendant had to exercise reasonable care in the light of the apparent risks involved. 2 Restatement (Second) Torts § 402 at 345 (1965); Prosser,
supra
§ 53. But even were we to assume that some general standard of care for inspecting and testing stoves existed, we find the record in this case devoid of evidence showing that the general standard was breached. The fact of the ocсurrence alone is inadequate proof of improper inspection and testing.
See San Antonio
v.
Warwick Club Ginger Ale Co.,
The plaintiff claims that she established the inadequacy of the preinstallation and postinstallation inspection and testing. With regard to the first inspection plaintiff called as a hostile witness a Providence Gas Company employee, John Bradshaw, who testified that nineteen years earlier another gаs company employee had performed a detailed twenty-one step check on the Scit-tarelli stove according to a check list dated November 2, 1959. The plaintiff pointed to no instance, however, where the inspector neglected to conduct one of the standard tests or inspections listed on the form, nor did she suggest a procedure not mentioned on the form thаt should have been followed.
The evidence of the postinstallation inspection was even less probative of negligence. The plaintiff merely elicited from Mr. Bradshaw that neither defendant nor the agents it hired to install the stove usually conducted the same inspection after installation as the gas company performed before delivery. There was no evidence of what aсtually took place during the installation of the Scittarelli stove.
Mr. Bradshaw did testify, however, that as a general practice the installers turned on a stove to ascertain if it operated after they completed the installation. On this evidence a jury could only speculate about whether defendant through its agents breached any actual or hypothetical duty to inspect or to tеst the stove once installed.
As additional evidence of defendant’s negligence plaintiff submits that an employee of defendant admitted responsibility for the accident. When plaintiff’s son, Joseph Scittarelli, telephoned the gas company after the accident to request a repairman, the person he spoke with responded, “Those things happen once in a while, you can’t help it. We’ll send somebody up.” Aside from the lack of evidence establishing the speaker’s identity, authority, and knowledge of the accident or of the workings of this type of stove, the statement in and of itself does not amount to a party admission of negligence. McCormick’s Handbook of the Law of Evidence, § 263 at 631-32, § 267 at 640 (2d ed. Cleary 1972).
The plaintiff also contends that she has established defendant’s negligence by excluding all other possible explanations for the aсcident. By stipulation the parties eliminated any negligence on the part of plaintiff as a cause of the accident. This falls short, however, of pointing to defendant as a negligent party. She was not, of course, required to eliminate all possible causes save defendant's negligence to escape a directed verdict, but she was required to introduce evidence from which defendant’s negligence could reasonably have been inferred.
Hill v. State,
R.I.,
II
The plaintiff additionally contends that the trial justice erred in directing a verdict for defendant on the
res ipsa loqui-tur
count. However, in order to recover under the doctrine of res
ipsa loquitur,
plaintiff must have established that the accident was one that in the ordinary course of events occurs when someone is negligent and that at the time of the accident defendant exclusively controlled the instrument of
*1045
plaintiff’s injury.

Carnevale v. Smith,
R.I.,
The quantum of proof necessary to meet the latter burden depends on the facts of each case. If the jury, relying on their common sense, would expect to find a negligent agency as the cause of the accident, the occurrence itself suffices to raise an inference of negligence.
E. g., Coia v. Eastern Concrete Prod. Co.,
Although we have not until now considered whether
res ipsa
should apply to cases where a gаs stove is the instrument of plaintiff’s injuries, other jurisdictions have held that the mere fact of an explosion in a gas stove, without additional evidence, is not sufficient to raise an inference of negligence, and therefore the doctrine is inapplicable.
Davis v. Aetna Ins. Co.,
In the instant case we conclude that plaintiff cannot avail herself of the
res ipsa loquitur
doctrine because without the aid of additional information about what actually occurred before and after the accident and what caused the door to open, a jury could only speculate that negligence on the part of defendant precipitated the event. As plaintiff asserts, most persons are familiar with the general operation of a stove and know that an oven door does not usually open by itself. Beyond this, however, а person of ordinary experience could not infer what caused the door to open and whether the cause involved negligence. The plaintiff produced no evidence of a malfunction in the stove other than a shattered glass window in the oven door. She claims an explosion in the oven caused the glass to shatter. But she did not present further evidence of an explosiоn, nor through expert testimony did she posit what one might expect to find at the scene of an oven explosion. Other possible theories, some of which do not implicate negligence, might explain how the oven door
*1046
shattered. On the facts in this record, however, no one theory is more probable than another. Accordingly, we find that plaintiff has failed to establish the likelihood that negligence precipitated the accident. Whether defendant has exclusive control over the stove, therefore, is irrelevant.
See Carnevale v. Smith,
R.I.,
Ill
The plaintiff also sought to establish defendant’s liability by alleging a breach of implied warranties of merchantability and of fitness for a particular purpose, 4 and by claiming that defendant should be held strictly liable for her injuries. 5 The trial justice submitted the case to the jury on the warranty counts.
As a threshold element of tort liability for personal injuries under each theory a plaintiff must prove that the defendant sold a defective product which posed a threat of injury to potential consumers.

Geremia v. Benny’s, Inc.,
R.I.,
The instant plaintiff hаs not produced direct or circumstantial evidence of a defect in her stove. Proof that the oven door opened does not tend to establish that the stove was defective.
See Geremia v. Benny’s, Inc.,
R.I.,
In support of her contention that she adduced sufficient evidence оf a defect in the stove, plaintiff has referred us to a recent opinion of the Appellate Division of the Superior Court of Connecticut,
Liberty Mutual Insurance Co. v. Sears, Roebuck & Co., 35
Conn.Supp. 687,
The plaintiff insurance company alleged that a defective television set which the insured had purchased from the dеfendant had burst into flames causing fire damage *1047 to real and personal property. The plaintiff could not, however, point to a specific defect in the charred remains of the television set.
Notwithstanding the lack of direct evidence of a defect the court stated:
“It is not necessary that the plaintiff in a strict tort action establish a specific defect so long as there is еvidence of some unspecified dangerous condition. * * * The jury may rely on circumstantial evidence to establish the dangerous condition of the product. In the absence of other identifiable causes, evidence of malfunction is sufficient evidence of a defect under § 402A.” Id. at 691,406 A.2d at 1256 (citations omitted).
Armed with these principles the court culled evidence tending to indicate the existence of a defect. Based on testimony pinpointing the set as the cause of the fire and establishing the normal use of the set prior to the fire, on evidence of the set’s malfunctioning, and on the common knowledge that nondefective televisions do not self-ignite, the court concluded that a jury could reasonably infer that the set was defective.
Id.
at 691,
While we find the reasoning of the Connecticut court perceptivе and its conclusions supportable, we believe the
Liberty Mutual
case is clearly distinguishable from the one before us. No one could have discovered the precise defect that must have existed in the television set because the fire reduced the set to ashes. Both parties in the case
sub judice
had ample opportunity after the accident to inspect the Scittarelli stove. Indeed, the repairman who examined the stove after the incident found no evidence of a defect. The circumstantial evidence of a defect in
Liberty Mutual
was so overwhelming that the inference that a defect existed was inescapable. In the case before us, however, the lack of evidence of a defect left the question open to speculation. Speculation will not suffice as proof of a defect.
Geremia v. Benny’s, Inc.,
R.I.,
After examining the record we conclude that the plaintiff has not produced sufficient proof of a defect in the stove to support an action in warranty or strict liability. Therefore, we hold that the trial justice erred by not directing a verdict for the defendant on both warranty counts, and we sustain his direction on the strict liability count.
For the reasons stated, the dеfendant’s appeal is sustained, the plaintiff’s conditional appeal is denied and dismissed, and the case is remanded to the Superior Court for entry of final judgment for the defendant.
Notes
. The defendant has appealed the denial of its pretrial motion to dismiss. Under Super.R. Civ.P. 41(b)(2) on motion of a defendant the Superior Court may, in its discretion, dismiss a complaint for lack of prosecution. In
Manton Industries, Inc. v. Providence Washington Indemnity Co.,
The instant defendant has not complained that the рassage of time between the assignment of the first trial date in 1963 to the actual trial in 1977 has worked to its prejudice; the defendant merely asserts that the elapse of fourteen years is reason enough to dismiss. On the contrary, under Rule 41(b)(2) and
Mantón Industries,
the trial justice must weigh the equities of dismissal between the parties. Accordingly, more than the fact of delay must be shown. Absent abuse, the trial justice’s exercise of discretion must stand.
Mantón Industries, Inc. v. Providence Washington Indemnity Co.,
. The plaintiff does not press the direction on the express warranty count as error.
. The third element of proof of res ipsa — the absence of plaintiffs contributory negligence— was not an issue in this case since the parties stipulated that plaintiff in no way caused the accident.
. Although the trial justice stated that the particular and the ordinary use of the stove was as a cooking device, defendant did not object to the failure of the trial justice to require plaintiff to show that she intended to use the stove for something other than its usual purpose before she could allege a breach of the warranty of fitness for a particular purpose.
See generally, D’Onofrio v. First National Stores, Inc.,
. The defendant cоntends that since this action accrued prior to any recognition by this court of the doctrine of strict liability, we should apply the rule of prospectivity in this matter. But because plaintiff failed to establish a defect in the stove, strict liability is not applicable. We therefore need not consider the question of whether the doctrine of strict liability should apply retroactively.
