STEWART, Justice:
The Stahelis, plaintiffs in this action, hired the defendant, Farmers' Cooperative of Southern Utah (Coop), to store 328,470 lbs. of barley pursuant to an oral contract of bailment. Fire of an unknown origin destroyed the warehouse and a large part of the stored grain. Other farmers who stored grain in the warehouse and sustained losses in the fire assigned their claims to the Stahelis who sued the Coop for the total amount of the loss. The trial court entered judgment for the Coop. The Stahelis' basic contention on appeal is that they were entitled to a presumption that the Coop was negligent as a matter of law and that the Coop did not rebut that presumption. It is conceded by the parties that there is no evidence as to actual cause of the fire.
The Coop is engaged in the business of providing grain storage for local farmers in Washington County, Utah. Generally it stores the grain in steel facilities, but in the fall of 1976 the Coop's warehouses could not accommodate the storage requirements of all the farmers in the area. Consequently, the Coop leased one-half of a large potato cellar owned by Stan Holt Cellar and Storage Company to provide temporary additional storage capacity. The portion of the cellar not leased to the Coop was retained and used by the owner for its purposes. There was no wall or partition between that part of the pit leased to the Coop and that part retained by Holt for its own use. The farmers whose grain was stored in Holt's potato cellar knew that the Coop was using that facility for their grain because they had hauled their grain into and out of the potato pit.
The potato pit was made primarily of wood and was surrounded by grass which could have been ignited by a lighted cigarette. The doors to that part of the cellar retained by Holt could not be locked to keep intruders out. The doors to that part of the cellar leased to the Coop were opened and closed by an electric motor; but at the time of the fire, the motor was not operating and the doors, having to be opened and closed by hand, were frequently left open. Burlap bags and a smudge pot containing oil had been left by a prior user of the pit in the Coop's portion of the storage facility.
The trial court expressly found that the Stahelis knew that their grain would be stored in the potato pit and that the owner of the pit retained possession of half the facility; the Stahelis as well as agents of the Coop had unlimited access to the pit through both the end leased to the Coop and the end retained by the owner; there were transients who were observed in or around the potato pit on October 6, 1976; and "the origin, cause or exact location where the fire commenced are [sic] unknown." In its conclusions of law, the trial court stated: "Defendant exercised the care that could reasonably have been expected under the circumstances and that no negligence on the part of the Defendant was shown by the Plaintiffs," and "without a showing of negligence on the part of the Defendant, Defendant is not responsible for the fire of unknown origin which caused the loss."
The trial court also wrote a thorough memorandum opinion, stating in considerable detail its reasons for ruling for the Coop. The court stated, inter alia:
On appeal, the Stahelis contend that by establishing the existence of their bailment contract and the failure of the Coop to return the bailed goods on request, they were entitled to the presumption that the fire was caused by the Coop's negligence. The Stahelis further contend that the Coop failed to establish its own due care. The Coop, on the other hand, maintains that the burden of proof did not shift to it because it did not have "`exclusive possession'" and therefore had no "`better opportunity to know the cause of injury or manner of the loss'" than the Stahelis. Sumsion v. Streator-Smith, Inc., 103 Utah. 44, 59-60, 132 P.2d 680, 687 (1943).
The general rule of law is that where goods bailed for a fee are damaged or destroyed a presumption of negligence is imposed on the bailee once the bailor proves the fact of bailment and damage to the bailed goods. The bailee must then come forward with evidence that the loss or damage was not due to the bailee's negligence.
Although the authorities are divided as to whether a fire of unknown origin is sufficient to rebut a prima facie case of negligence established by the presumption, 8 C.J.S. Bailments § 50 (1962), the rule in this jurisdiction is that if the factual preconditions for imposition of the presumption are met, a fire of unknown origin is presumed to have been caused by the bailee's negligence and the bailee must then shoulder the burden of showing lack of fault. Barlow Upholstery & Furniture Co. v. Emmel, Utah, 533 P.2d 900 (1975); Wyatt v. Baughman, 121 Utah. 98, 239 P.2d 193 (1951); cf. Romney v. Covey Garage, 100 Utah. 167, 111 P.2d 545 (1941).
The policy that sustains the presumption arises from the practical consideration that one who is in possession of another's property is in a better position to control the conditions that may cause loss or damage and to know, or at least to be able to ascertain, the cause of any actual loss or damage. A predicate of the presumption, therefore, is that the bailee be in exclusive possession, and it is that proposition that gives logical force to the presumption. Sumsion v. Streator-Smith, Inc., 103 Utah. 44, 132 P.2d 680 (1943). The Court in Sumsion stated: "The cases almost universally hold that this inference of negligence will not arise in those cases where the bailor shows by his pleading or proof that he had the same opportunity to ascertain the facts as did the bailee. It is a rule based on necessity and will not apply if the necessity does not exist." Id. at 60, 132 P.2d at 687. In addition, the bailee's expectation of making a profit would normally lead a prudent person to take appropriate care of the entrusted property. See Romney v. Covey Garage, 100 Utah. 169, 111 P.2d 545 (1941).
Notwithstanding the presumption, the law does not make the bailee for hire a guarantor; it is a rule of fault with which we deal. Thus, the presumption allocates the burden of proof to the party most likely to have access to the evidence and, in the absence of evidence, places liability on the party most likely to have been able to avert the loss.
This Court has observed that the evidentiary rules governing bailment are in some respects similar to those governing the doctrine of res ipsa loquitur, although there are important procedural differences. Romney v. Covey Garage, 100 Utah. 167, 111 P.2d 545 (1941).
The record in this case clearly establishes that the Coop did not have "the right or power of control." The trial court's findings are unchallenged that Holt, the Stahelis, and the Stahelis' assignors had lawful access to the potato pit. Indeed, the trial court specifically found that "Plaintiffs, as well as the agents of the Defendant, had unlimited access to the said potato pit either through the doors on the end temporarily leased by the Defendant or through the doors on the end retained by the owner, neither of which was locked." Furthermore, it is not even established whether the fire started in that part of the facility retained and controlled by Holt or in that part leased by the Coop.
We readily concede that the record contains evidence of carelessness on the Coop's part, but there is also evidence of the Stahelis' negligence and, indeed, the possibility of negligence on the part of third parties. The retention of the oil-filled smudge pot and burlap bags in an area of the pit accessible through both Holt's side and the Coop's side, as well as the existence of intruders in the vicinity who sought shelter in the warehouse, raises the possibility that any of the above-mentioned parties may have negligently started the fire. Furthermore, the fire could have been caused by a lighted cigarette thrown on the grass near the wood structure or by spontaneous combustion, as the trial court suggested.
The right to control these events and conditions was not exclusively or even primarily the duty of the Coop. Indeed, the lack of control and adequate precautions was a result, to some extent, of the emergency situation arising from the need to store surplus grain beyond that which the Coop's facilities could accommodate. In sum, the trial court properly held that a presumption of negligence did not arise because of the absence of the Coop's exclusive control of the premises. Under the circumstances the Coop was in no better position than the Stahelis to know, or to be able to ascertain, the cause of the fire or to control several of the possible causes of the fire.
Finally, the Stahelis failed to make out a case based on the specific acts of negligence alleged in the complaint, irrespective of a presumption, because of the absence of proof of the proximate cause of the fire. When the proximate cause of an injury is left to speculation, the claim fails as a matter of law. Sumsion v. Streator-Smith, Inc., 103 Utah. 44, 132 P.2d 680 (1943).
