Opinion by
Mr. Justice Horace Stern,*413Notwithstanding the tragic death in this case of plaintiffs decedent, the jury, in an action brought by the administratrix of his estate under the Wrongful Death and Survival Acts, found a verdict in favor of the original defendants, and we are constrained to hold, on plaintiffs present appeal, that the court below acted properly in refusing her motion for a new trial.
The jury found a verdict in favor of the plaintiff against the additional defendant, who, however, was decedent’s employer and therefore liable to him only under the Workmen’s Compensation Act; accordingly the court below entered judgment for this defendant n.o.v., and from that judgment no appeal has been taken.
The controlling facts are, briefly, as follows: Edward J. Eeider and Minnie M. Eeider, the original defendants, were the owners of a two-story commercial property in Eochester, Beaver County. In 1946 they had a hot-water heater installed on the second floor for the purpose of supplying hot water to the tenants. Its fuel was natural gas; it was enclosed in a small closet and, although it was provided with an opening for that purpose, it was not fitted with a vent to carry off the fumes produced by the heater when burning and which were released instead, by means of a hole cut through the ceiling of the closet, into a loft space between the ceiling of the second floor and the roof of the building. This space, 60 feet in length and 18 feet in width, was but 28 inches high at its highest point; it was a dark area without any opening to provide an exit for the gas fumes ascending from the heater below, and it thus constituted what amounted practically to a reservoir for the accumulation of the carbon monoxide gases, which are colorless, tasteless, almost odorless, and deadly upon extended inhalation. At the time the heater was installed defendants were advised by the contractor who did the work that a fresh air vent *414ought to be attached to it and the contractor recommended to them a tinner for that purpose, but they made no attempt to have such a vent constructed. At different times thereafter their attention was called to the danger of the condition thus created and they were urged to have it corrected, but nothing was done.
In 1947 defendants entered into a contract with Hershel Routman, the additional defendant, for the installation by the latter of a furnace on the second floor of the property adjacent to the hot-water heater. This furnace was to be electrically controlled, and for that purpose Routman decided that the necessary connection could best be made with a wire which ran across the space above the furnace and which could be reached by going into that space through the hole above the heater in the closet. Two of Routman’s employees, Joseph C. Smith and the decedent, Raymond H. Engle, worked on the job for a few days; on the day of the accident Smith left there for about an hour to return to the shop, and during his absence Engle, in order to reach the point where the splice or connection to the wire was to be made, crawled through the hole in the closet and wormed his way for a distance of some seven feet into the compressed space of the loft. When Smith returned he found Engle lying dead on the floor of the loft as a result of his having inhaled the carbon monoxide gas produced by the hot-water heater.
At the trial Routman testified that he had visited the Reider property several times before and during the installation of the furnace, had examined the premises, looked into the closet, seen the hot-water heater there and noticed there was no vent on the tank, and that he was fully aware of the resulting danger of carbon monoxide poisoning; he also testified that, according to his best recollection, he had discussed the matter with Reider on the first day on which the furnace was being installed and had called his attention to the *415fact that the heater was not properly vented and that it was dangerous. Realizing, as he did, the hazard of working over the top of the heater, he instructed Smith to he sure to turn the gas off before going up into the loft. Smith, in turn, testified that he said to Engle that the heater should have been vented and was dangerous ; also, that when he left to go to the shop he told Engle to be sure to turn the gas off before he entered the loft, to which Engle replied “O.K.”. Engle did not turn off the gas; the pilot light was on and the gas was burning when Smith returned and discovered Engle’s body.
The learned trial judge charged the jury that, while he would leave it to them to decide, it seemed to be undisputed that the contractor, Routman, well knew that there was a dangerous situation there caused by the failure to have a vent pipe that would carry the carbon monoxide fumes into the open air, and had warned his employee Smith accordingly. The jury was then instructed that “The extent of the duty of the owner of a building who employs an independent contractor to the latter’s employees (that is, Routman’s employee, Engle) with respect to known or discoverable dangerous conditions existing on the premises where the work is to be done, is to warn the contractor of their existence; he is not required to warn every sub-contractor and laborer who comes on the premises. In this case, . . . the Reiders had no obligation to warn Engle, an employee of Routman. His full duty was performed with regard to this dangerous condition when he warned the contractor Routman. If you find that he did warn the contractor Routman; or, if you find that Routman did not need to be warned because of his superior knowledge of the danger of unvented flues, or because of his having visited the premises five or six times he saw, or ought to have seen this obvious danger and realize it — and he says he did — then Reid-*416er’s full duty to those business visitors, Routman and Engle, was to notify Routman, or be sure that Routman knew of the existence of this condition which was dangerous; and if he had done that he did not need to go farther, he did not need to go as far as to notify Engle.” The court further charged the jury that “the burden is affirmatively on the plaintiff (Mrs. Engle in this case) to prove the employer’s [owner’s?] (Reider’s) failure to notify the contractor of the existing dangerous condition. There was no attempt made to show that. As a matter .of fact, on cross-examination of Routman it was developed that Routman did know of the existence of this dangerous situation, and that he did nothing about it, except, as he says, that he warned Smith not to, under any circumstances, go up into that cubbyhole in the roof without first turning off the gas for a sufficient length of time to have the carbon monoxide dissipated. He doesn’t say that he notified Engle; that wasn’t developed. The burden is upon the plaintiff to show affirmatively that the Reiders did not notify the contractor.”
These instructions were in complete accord with the law of Pennsylvania on the subject thus discussed. In Newingham v. J. C. Blair Co., 232 Pa. 511, 520, 521, 81 A. 556, 560, the following quotation from White’s Supplement to Thompson on Negligence, sec. 979: “It is the rule that the owner of property owes to an independent contractor and his servants at work thereon, the duty of exercising reasonable care to have the premises in a safe condition for the work, unless the defects responsible for the injury were known to the contractor. . . .” was commented upon as enunciating a “sound, general rule.” Authority to the same effect is to be found in Nettis v. General Tire Co. of Philadelphia, Inc., 317 Pa. 204, 209, 210, 177 A. 39, 41, 42. There then followed the decision of this Court in Valles v. Peoples-Pittsburgh Trust Co., 339 Pa. 33, 13 A. 2d *41719, where the subject of the liability of a property owner to the employees of a contractor called to work upon the premises to warn such employees against latent dangers was comprehensively discussed in an opinion by Mr. Justice Linn and it was held that the extent of the duty of the owner of a building under such circumstances was to warn the contractor of the existence of dangerous conditions, but that he was not required to warn every sub-contractor and laborer who came on the premises, — that his responsibility to an independent contractor’s employees while performing the contract on his premises was not the same as his responsibility to his own employees; furthermore, that it was a necessary and essential part of the plaintiff’s case to prove that the property-owner failed to notify or warn the contractor and that the latter did not have knowledge thereof. In the present case plaintiff made no attempt to prove that the contractor was uninformed as to the danger; on the contrary, the contractor himself testified that he was fully aware of it and had discussed it with defendants themselves. If, as the court instructed the jury, they believed Routman’s testimony to that effect, their verdict in favor of defendants necessarily followed from the law laid down in the Valles case.
There is another, equally potent reason why plaintiff’s right to recovery is barred in this case. The learned trial judge submitted several special interrogatories to the jury, one of which was as follows: “Was Raymond H. Engle negligent in crawling up over the tank into the space between the ceiling and roof without shutting off the gas and waiting a reasonable length of time for the fumes to clear away, and without having someone near at hand to help him in the event that any trouble developed?” To this interrogatory the jury answered: “Yes (Partially).” “Partially” must be understood as meaning “to some extent”, but, of course contributory negligence even in the slightest degree *418destroys the right of recovery. There was ample justification in the testimony for the jury’s finding. As already stated, the witness Smith testified that he had warned Engle to turn the gas off before entering the loft and that they had discussed the dangerous condition arising from the fact that the heater was not vented. It is true that Smith admitted that he had not previously told anyone of such warning and discussion but the jury had the right to believe the testimony he gave at the trial and from it, and from all the other circumstances in the case, to conclude that Engle had been “partially” negligent in entering and crawling back into the loft although he was aware of the danger involved. While the jury’s verdict in favor of plaintiff against the additional defendant was inconsistent with their special finding of contributory negligence, and even if, in such case, the special finding be not held as absolutely controlling (although plaintiff’s counsel frankly concedes the contrary), certainly the court was not bound, in the exercise of its discretionary power, to grant a new trial, on that account, as to the original defendants. Plaintiff urges, however, that the Reiders should not be permitted to avail themselves of the defense of contributory negligence because their negligence amounted to reckless or wanton misconduct (Kasanovich, Administratrix, v. George, 348 Pa. 199, 34 A. 2d 523; Misorski v. Pennsylvania R.R. Co., 348 Pa. 204, 34 A. 2d 526). This contention, not made at any stage of the trial, is raised for the first time in this Court, but, apart from that fact, and even though defendant’s negligence may have been gross, it cannot properly be characterized as wanton. The distinction between gross negligence and wanton misconduct was explained in the Kasanovich case (p. 203, A p. 525) as being a difference not merely in degree but in kind; the cases in which wanton misconduct was found to exist were those in which the tortfeasor had actual knowl*419edge of a victim’s peril but nevertheless pursued bis tortious course with utter indifference to the outcome; (see Slother v. Jaffe, 356 Pa. 238, 242, 243, 51 A. 2d 747, 749, 750.) Allowing the gases to accumulate in the loft did not in itself constitute wanton misconduct; only if Beider was responsible for Engle’s entering there without being warned of the danger could he possibly have been so charged. In view of Routman’s testimony that he had called Beider’s attention to the fact that the heater was not properly vented and was therefore dangerous Beider was justified in assuming that Boutman, aware of the danger, would warn his employees accordingly. “A possessor of land is subject to liability for bodily harm caused to business visitors by a natural or artificial condition thereon if, but only if, he (a) knows, or by the exercise of reasonable care could discover, the condition which, if known to him, he should realize as involving an unreasonable risk to them, and (b) has no reason to believe that they will discover the condition or realize the risk involved therein, . . .” Restatement, Torts, §343. The jury were asked in a special interrogatory: “Did Edward J. Beider and Minnie M. Beider have any reason to believe that Hershel Boutman, or his agents, would discover the condition of the unvented hot-water heater or realize the risk involved therein?” Their answer was “Yes.” On the whole, therefore, the jury could not have found on the testimony in this case that, however great the negligence of which the Beiders were guilty, it constituted wanton misconduct within the legal concept of that term.
It appearing from all angles, therefore, that the verdict of the jury in favor of the original defendants was fully justified by the evidence, the court properly denied the motion for a new trial. As far as the verdict against the additional defendant, Boutman, was concerned, the court entered judgment n.o.v, thereon be*420cause, lie being Engle’s employer, and it baying been stipulated at tbe trial that be bad entered into an agreement for workmen’s compensation for Engle’s death wbicb agreement remained in force and was being complied with, tbe verdict against bim in favor of plaintiff could not, of course, be sustained.
Judgment affirmed.
