GOOD, J. pro tem.[1]
Plaintiff and plaintiff in intervention appeal from a judgment of nonsuit in an action for personal injuries sustained at plaintiff’s place of employment when an explosion occurred in the immediate area of a gas burner that had been manufactured by defendant Anthony Company and sold and installed by defendant Natural Gas Equipment, Inc. The two companies will be referred to as Anthony and Natural Gas. Plaintiff was employed as a fireman by Marks Materials Company, which was engaged in the production and sale of a black-top mix used in road paving. The burner was used in connection with a rotary drier to dry sand and gravels used in the mix. With the exception of the occasional intervention of the plant foreman, plaintiff was the only person who operated the burner or drier. Until four or five weeks before the explosion, the drying had been done with an oil burning unit. After installation of the gas unit, the burner involved produced the required silver blue flame and appears to have operated satisfactorily except that the quantity of aggregates dried had to be reduced somewhat. On the day of the accident, the burner was shut off at noon and relit about one-half hour later. It had been “working fine” during the morning. Shortly after relighting it, plaintiff noticed that the thermometer indicated a drop in the temperature of the drier. He cheeked the gas and air valves and gauges for proper pressures and on checking inside the drier noticed that instead of being blue, the flame was a reddish-orange color. Within minutes there was
* Assigned by Chairman of Judicial Council.
Plans and specifications for conversion from oil to gas were prepared by Natural Gas and the burner unit specified thereon was furnished by Anthony. The drier is a rotating brick-lined kiln 22 feet long with an inside diameter of about 5 feet into which the flame is blown from the separately installed burner. Schematic diagram and manufacturer’s description of the burner is contained in Anthony’s Data Sheet admitted in evidence herein. It may be noted that the burner actually installed appears to have been not exactly the same as that shown on the exhibit but design and operating principles insofar as gas is concerned were the same. There was testimony that natural gas under three to five pounds pressure and air under one to three pounds pressure were separately introduced into a mixing chamber and forced out of the orifice of the air adjusting cap, ignited by a pilot light and the flame then blown into the rotating kiln. The air cap was 12 inches in diameter and threaded to screw onto the burner head. The threads were coarse and free-running to permit easy adjustment of the space between the gas nozzle and the cap’s face, thus increasing or decreasing the air space in the mixing chamber. No lock or set screws were provided for the cap except when specified by the purchaser. A vice-president of Anthony testified that the unit was manufactured to provide a minimum of 14-inch air space with the cap screwed tight but that the tolerance was variable and it was conceivable that the space could be reduced to' % inch; that because of the coarseness of threads it would take a great deal of force to further close the space by stripping the threads; that the gas nozzle and air deflector were also threaded and could be moved forward toward the air adjusting cap but that set screws fixed its position; that the ]4-inch minimum space would not provide a satisfactory operation but that it was the practice to assemble the unit for shipping with the air cap screwed tight because the space between cap and nozzle had to be adjusted to suit each particular job and that once adjusted for proper burning it should not be “monkeyed with”; that if the %-inch minimum space was entirely closed it would be reasonable to assume that gas at the greater pressure could be forced back into the air line; and, also, that he did not know what actually caused the explosion.
There was also evidence that before installing the burner
The issues raised are (a) whether or not the evidence was sufficient to support a finding of negligence against either or both defendants under res ipsa loquitur; (b) whether the evidence without the application of res ipsa would support a finding of negligence because of unsafe or defective design or by reason of failure to instruct or caution appellant or his employer in the safety factors involved in the operation of the burner and its various adjustments; and (e) whether or not it was prejudicial error to exclude expert testimony on the question of accepted engineering standards of design and safety requirements in the San Francisco Bay area. These issues will be discussed in the order stated.
The adversaries have correctly cited the principles of law governing the granting of nonsuit and appellate review there
Was res ipsa loquitur applicable? In our opinion there was prima facie proof sufficient to require submission of the question to the jury. The doctrine has three factual conditions (1) the accident must be of a kind which ordinarily does not occur in the absence of someone’s negligence ; (2) it must be caused by an agency or instrumentality within the exclusive control of the defendant; (3) it must not have been due to any voluntary action or contribution on the part of the plaintiff. (Ybarra v. Spangard (1944), 25 Cal.2d 486 [ 154 P.2d 687 , 162 A.L.R. 1258 ]; Baker v. B. F. Goodrich Co. (1953), 115 Cal.App.2d 221 [ 252 P.2d 24 ].)
It is well settled that the first condition is satisfied if there is a basis of experience, either common to the community or brought out in evidence, from which it may reasonably be concluded that the accident is of a kind which does not ordinarily occur unless someone has been negligent. (Hercules etc. Co. v. Automatic etc. Corp. (1957), 151 Cal.App.2d 387 [ 311 P.2d 907 ]; Zentz v. Coca Cola Bottling Co.,
In order to satisfy the second condition of the doctrine, it is not necessary to show that a defendant had control of the instrumentality at the time of the accident where the evidence shows that, after a defendant relinquished control, the instrumentality had not been changed and that it had not been mishandled. (Burr v. Sherwin Williams Co. (1954), 42 Cal.2d 682 [ 268 P.2d 1041 ]; Ybarra v. Spangard, supra.) The respondents cite Trust v. Arden Farms Co. (1958), 50 Cal.2d 217 [ 324 P.2d 583 ] on the duty which the plaintiff has to establish that there has been no change in the condition of the instrumentality. Respondents argue that there the court in finding this condition not satisfied relied on the fact that the plaintiff did not have her children testify as to access to or handling of a milk bottle that had been in the refrigerator for four days. Respondents empha
Before leaving this second condition another argument of Natural Gas must be examined. Tobola v. Wholey (1946), 75 Cal.App.2d 351 [ 170 P.2d 952 ] is cited for the proposition that where testimony involves a physical impossibility it must be ignored. It is their theory that the condition of the air cap must have changed since they argue the burner could not have operated for three weeks with the air cap in the tight position. The appellant points out that all of the cases which have formulated the “impossibility” rule (except for Lind v. Closs, 88 Cal. 6 [ 25 P. 972 ], which was unusual in that it was a rape case) have done so indictum. Appellant claims the rule is that before evidence can be rejected as inherently impossible, the physical impossibility must be shown by evidence or must be apparent without resort to deductions. (Brown v. Guy (1959), 170 Cal.App.2d 256 [ 338 P.2d 586 ] ; Anderson v. Joseph (1955), 136 Cal.App.2d 382 [ 288 P.2d 524 ] ; Kahn v. Lischner (1954), 128 Cal.App.2d 480 [ 275 P.2d 539 ] ; Evje v. City Title Ins. Co. (1953), 120 Cal.App.2d 488 [ 261 P.2d 279 ].) It must be noted that in all these cases credibility had been determined and evidence had been believed by the trier of fact below. Because of the nonsuit, that feature is here lacking. However, a compelling analogy exists because, as above noted, the plaintiff’s evidence must be given all possible weight, and credibility is not in question. Respondent’s theory does not accord with testimony of an officer of Anthony called under Code of Civil Procedure, section 2055 that if the cap were completely shut it would be “a poor operation.” He did not testify that the burner could not operate. In fact, with the cap shut there should have remained the %-inch opening for the passage of air. Further, the diagram and testimony shows that the nozzle itself could go forward, thus closing the critical space. In view of these factors, the respondent’s theory is without merit both as to this point and when raised again in answering appellant’s contentions on specific evidence on negligence.
The third condition for application of res ipsa loquitur may be satisfied even where a plaintiff has participated in the events leading up to the accident, if the evidence excludes his conduct as a responsible cause. (Zentz v. Coca
The analysis of the conditions which are required for the application of res ipsa loquitur indicates that evidence was present in the record which could have satisfied the doctrine. In considering the applicability of the doctrine, it is not for the trial court to draw the conclusion as to whether a defendant’s negligence is or is not the more likely explanation of the accident. The question turns on whether the plaintiff has produced sufficient evidence to permit a jury to draw such inference and not whether the court itself would draw it. Where reasonable men may differ as to the balance of probabilities, the court must leave the question to the jury. (Bauer v. Otis (1955), 133 Cal.App.2d 439 [ 284 P.2d 133 ] ; Seneris v. Haas, supra; Hercules etc. Co. v. Automatic etc. Corp., supra.) Where, as here, there is evidence that would support the application of res ipsa loquitur the granting of a nonsuit is erroneous. (Raber v. Tumin, supra; Hinds v. Wheadon, supra; Towers
The next major issue is whether there was sufficient evidence on negligence, unaided by the doctrine of res ipsa loquitur, to allow the question to go to the jury. It is clear that proof of specific negligence does not preclude application of res ipsa loquitur, or vice versa. (Towers v. Massey-Harris Co., supra; Fedler v. Hygelund (1951), 106 Cal.App.2d 480 [ 235 P.2d 247 ].)
The appellant points out, as to Anthony, that irrespective of privity of contract where an article is either inherently dangerous or reasonably certain to place life and limb in peril when negligently made, a manufacturer owes a duty of care to those who are the ultimate users. (Kalash v. Los Angeles Ladder Co. (1934), 1 Cal.2d 229 [ 34 P.2d 481 ]; Nebelung v. Norman (1939), 14 Cal.2d 647 [ 96 P.2d 327 ]; Maecherlein v. Sealy Mattress Co. (1956), 145 Cal.App.2d 275 [ 302 P.2d 331 ] ; Larramendy v. Myres (1954), 126 Cal.App.2d 636 [ 272 P.2d 824 ].) This duty requires reasonable care to be exercised in assembling component parts and inspecting and testing them before the product leaves the plant. (Post v. Alameda Amusement Co. (1953), 117 Cal.App.2d 588 [ 256 P.2d 580 ].) Where an article is a dangerous instrumentality, the suppliers thereof (this would include both Anthony and Natural Gas as the term applies to both sellers and installers) have a duty to exercise care commensurate with the danger involved. The appellant correctly cites Dow v. Holly Manufacturing Co., 49 Cal.2d 720 [ 321 P.2d 736 ] [gas heater] ; Warner v. Santa Catalina Island Co., 44 Cal.2d 310 [ 282 P.2d 12 ] [shooting gallery] ; Johnson v. Nicholson, 159 Cal.App.2d 395 [ 324 P.2d 307 ] [gasoline] for this proposition. 2 Within’s Summary of California Law (7th ed.), page 1414, section 220, also points out that this duty exists when the instrumentality involves a volatile gas, which has been held to be inherently dangerous. There is evidence of the existence of inherent danger in the testimony that if the cap were shut tight (the position it was found in after the accident), it could cause the gas to bach up and mix with. air. There is, therefore, evidence on
There was also evidence present which should have allowed the jury to consider the possible breach of the duty of care by Natural Gas in installation of the burner. The danger present when the air cap was closed has been indicated in the preceding discussion. Although Natural Gas in deposition indicated it adjusted the air cap in a preliminary test, there is evidence which is contradictory. The cap was closed when shipped by Anthony, and it was found in that position when examined after the accident. Further, a negative inference exists that the set screws to fix the position of the nozzle were not checked during installation. The plaintiff and his foreman were the only persons who operated the equipment and testified that neither they nor anyone else ever adjusted the cap or other parts of the burner head. The jury should have determined from the conflicting evidence whether there had been a duty to plaintiff which had been breached here.
It is with regard to this point that the respondent Natural Gas again raises the contention that it would have been physically impossible for the burner to operate with the air cap in the shut position. The same reasoning which disposed of this argument on the res ipsa loquitur argument, supra, compels a determination that the contention is without merit.
There is another duty which must be considered. There was evidence discussed earlier to the effect that the shut position of the cap could force gas into the air passages and that this could cause an explosion. This was known to respondent Anthony Company and should have been known to respondent Natural Gas, whose business is to install such gas heaters. The plaintiff would be in the class of persons reasonably to be expected to be in the vicinity of the equipment while it was operated for the purpose for which it was supplied. There is testimony to the effect that no one told the appellant or foreman about the danger involved in operating the burner with air space closed. A jury could
The record thus furnishes at least some support for an inference of actual negligence, the factors being known to both Anthony and Natural Gas. The test of foreseeability having been met, an inference as to proximate cause exists since no other causes were shown to intervene regarding Natural Gas and any evidence present as to Natural Gas’ installation intervening as to Anthony presented a question of fact for determination by the jury. In view of the foregoing, there was sufficient evidence of actual negligence to require the jury to resolve the issue.
Finally, appellant contends that the court erred in preventing him from eliciting expert testimony as to whether the burner’s design met with the general engineering standards of safety in the area, and as to whether anything could have been done to make it safer in its operation. Proper foundation as to qualifications by way of general education and experience as well as knowledge of the particular operation was established. An objection to a question as to whether
While the admission or rejection of expert testimony lies largely within the discretion of the trial court, and its action will not be disturbed on appeal unless there is a showing of abuse of this discretion (Davenport v. National Reserve Ins. Co., 91 Cal.App. 460 [ 267 P. 132 ]), the test is whether the case is one outside the common experience of men so that a person with superior knowledge because of training and experience is better able to reach a conclusion from the facts. (Manney v. Housing Authority, 79 Cal.App.2d 453 [ 180 P.2d 69 ]; Wells Truckways, Ltd. v. Cebrian, 122 Cal.App.2d 666 [ 265 P.2d 557 ].) It has been held that evidence is admissible to show the necessity and feasibility of adding a safety device to machinery and, also, whether machinery is properly equipped or adjusted. (Young v. Bates Valve Bag Corp., 52 Cal.App.2d 86 [ 125 P.2d 840 ] ; Mulholland v. Western Gas Constr. Co., 21 Cal.App. 44 [ 131 P. 110 , 113] ; Pitt v. Southern Pacific Co., 121 Cal.App. 228 [ 9 P.2d 273 ].) Vedder v. Bireley, 92 Cal.App. 52 [ 267 P. 724 ], held it was prejudicial error to exclude expert opinion as to whether brakes were in proper condition to function. In view of appellant’s proffer and the holdings of the eases cited, as well as many others, the trial judge was not correct in his comment that expert evidence was not admissible and that the jury could form its own conclusions from the plans themselves.
The determinative question is whether the trial court abused its discretion in barring this line of expert testimony, for as pointed out earlier, and as noted by respondent, there can be no prejudicial error where the refusal is not an abuse of discretion. The question is answered by determining if the party barred from introducing such expert testimony has been denied a fair opportunity to prove his ease. If so, the exclusion requires reversal. (Jones v. Johnston Testers, Inc., 132 Cal.App.2d 162 [ 281 P.2d 602 ]; Agnew v. City of Los Angeles, 97 Cal.App.2d 557 , 558 [ 218 P.2d 66 ].) Here, a foundation was laid, and the proffered testimony was within the proper scope of expert opinion. The evidence was both material and relevant, since it went to the issue of standard of care and breach as well as being relevant to causation. Under the circumstances of the case, the exclusion of the proffered expert testimony was prejudicial.
The judgment is reversed. The appeals from the order granting a motion for nonsuit, a nonappealable order, are dismissed.
Kaufman, P. J., and Draper, J., concurred.
A petition for a rehearing was denied October 20, 1960, and respondents’ petitions for a hearing by the Supreme Court were denied November 16,1960. Schauer, J., and McComb, J., were of the opinion that the petitions should be granted.
