324 Mass. 623 | Mass. | 1949
This is an action of tort to recover for personal injuries sustained by the plaintiff in an explosion alleged to have been caused by the defendant’s negligence. The plaintiff had a verdict which was recorded under leave reserved. Thereafter the judge entered a verdict for the defendant. The plaintiff brings the case here on exceptions challenging this action and various rulings made during the trial. The defendant also comes here on exceptions but presses them only if the plaintiff’s exceptions are sustained.
A summary of the pertinent portions of the evidence most favorable to the plaintiff is as follows: On February 6, 1942, the defendant installed a gas burner, controlled by a thermostat, in the furnace of a house which was owned and occupied by the plaintiff’s parents with whom the plaintiff lived. The furnace was connected with a chimney, about six feet away, by means of an eight inch flue. This flue “as installed by the defendant ran from the furnace to the chimney in a horizontal line without pitch or rise and sagged in the middle.” The burner contained a safety device designed to prevent gas from flowing into the burner in the event the pilot went out.
On September 24, 1945, the defendant installed an automatic gas hot water heater near the furnace. It had a three inch flue which was joined by “a short right angle connection” to the eight inch flue, mentioned above, at a point about midway between the furnace and the chimney.
In March of 1945 the defendant cleaned the pilot in the furnace and also the flue, and in May turned off the gas for the summer. On August 1, 1945, “there was a general
About ten o’clock on the morning of February 3, 1946, the plaintiff’s father smelled gas and went downstairs to the basement. He looked through a crack between the door and the casing of the furnace and could see no flame, but he “could hear the sound of gas going into the burner of the furnace.” He called the plaintiff who came down to the basement, and while the plaintiff was in front of the furnace “he heard the hot water heater go on and then there was an explosion which blew out the part of the flue pipe which was between the furnace and the hot water heater, the firebox door, and also the small clean-out door at the top of the furnace.” At seven o’clock on the morning of the accident a wood fire had been lighted in the stove next to the heater and there “was still a little fire ... [in it] after the explosion . . . but ... it was low and there were no sparks.” As a result of the explosion the plaintiff was severely injured. Evidence in addition to that set forth above will be recited hereinafter as occasion requires.
The plaintiff’s exception to the entry of the verdict for the defendant under leave reserved raises the following questions: (1) whether the defendant has violated any duty of care owed by it to the plaintiff, and (2) whether, if there was such a violation, it caused the injuries of which the plaintiff complains. The plaintiff contends that, irrespective of what caused the excessive accumulation of gas in the furnace and flues, the explosion was caused by the right angle or “T” connection and that the installation of this type of connection by the defendant was a breach of duty owed to the plaintiff. The plaintiff also contends that the explosion could have been found to be caused by the defend
We shall deal with the latter question first. The evidence on this issue came entirely from experts. One expert, Hesselschwerdt, called by the plaintiff, testified that “There is a possibility that with the ignition of this gas heater . . . a tongue of flame, or an incandescent spark of carbon could have gone up conceivably through . . . [the] stack pipe, out into the main breaching ... and caused an explosion somewhere in . . . [the] line,” that if “the right angle connection were not there, there would be a longer travel for that spark to become extinguished, and only the products of combustion could have gone into the breaching.” On cross-examination this witness qualified this testimony by saying that on the facts assumed by him as the basis for his opinion it was not possible that a tongue of flame could extend up through the heater and into the stack, and that there would be no more “than a speculative possibility that any spark would go up the stack from the water heater” if the heater was operating normally. (There was no evidence that the water heater was not operating normally.) It may well be that this evidence leaves the issue of causation in such an atmosphere of guesswork and speculation that it would not afford the basis of a finding that there was a causal relationship between the installation and the explosion. The opinion, as qualified, would seem to be no more than an “expression of conjecture.” Brownhill v. Kivlin, 317 Mass. 168, 170. But this evidence did not stand alone. Another expert, one Goldberg, who had had forty to fifty years experience as a master gas fitter, testified that in his opinion the right angle or “T” connection was the cause of the explosion. His explanation of how the explosion occurred
Whether the installation made by the defendant was one which would be likely to cause an explosion of the sort occurring here was not a matter of which the jury could be expected to know from their common knowledge and experience. The subject was a proper one for expert testimony. Jackson v. Anthony, 282 Mass. 540, 544. Flynn v. Growers Outlet, Inc. 307 Mass. 373, 376. On the basis of Goldberg’s testimony the jury would be warranted in finding that the connection installed by the defendant caused the explosion by permitting the escaping gas to flow down the flue into the hot water heater. We cannot say that this opinion is so “contrary to common sense or to known natural laws of which the court can take judicial notice” that it must be disregarded. Ruschetti’s Case, 299 Mass. 426, 430-431. The defendant contends, however, that Goldberg’s testimony should be put out of the case since it rested on an assumption that the water heater was constructed with an air space that continued “up the sides of the storage tank” whereas in fact the heater was constructed with a flue through the middle of the boiler. This contention is without merit. It is true that Goldberg gave his opinion on the assumption that an air space existed on the side of the tank. And it is also true that after making a second inspection of the water heater during the trial he was recalled and admitted that it was constructed with a flue in the center. But he stated that this would not change the opinion which he had previously given.
The defendant owed a duty to the plaintiff to install the water heater in “a workmanlike manner, with reasonable judgment, skill and care, according to the approved usages of . . . [[the] trade.” Kelley v. Laraway, 223 Mass. 182,
Considering the evidence which was introduced together with that which was erroneously excluded, we think that the plaintiff was entitled to have the jury determine whether the defendant was negligent and, if so, whether such negligence was causally related to the explosion. It was, therefore, error to enter a verdict for the defendant under leave reserved, and the plaintiff’s exceptions must be sustained.
It becomes necessary to consider certain exceptions taken by the defendant. The judge in his charge, among other things, told the jury in substance that they could find for the plaintiff if the defendant cleaned the burner in the furnace improperly, provided such improper cleaning caused the explosion. The defendant excepted to this portion of the charge. This exception must be sustained. It is true that there was evidence that the improper cleaning of the pilot could be an adequate cause of an explosion of the
Plaintiff’s exceptions sustained.
Defendant’s exceptions sustained.
This type of connection was sometimes referred to in the testimony as a “T” connection.
Another regulation (part of § 19) which was offered in evidence provided that “No horizontal flue greater in length than twenty feet shall be allowed and for long runs a pitch or rise of at least one half inch to the foot shall be maintained from the appliance to the chimney.” This was rightly excluded. If we assume in favor of the plaintiff that a violation of this regulation was shown — a matter by no means free from doubt — it would have no relevancy here because it was not shown beyond conjecture that there was any causal relation between the lack of a pitch or rise and the explosion.
