The only question is, whether there was evidence justifying the submission of the case td the jury.
The plaintiff was injured, while temporarily in the defendant’s employ, by the. explosion of a soda tank. He was employed as a drug clerk in another store, but on the day of the accident went to the defendant’s place of business and took charge of it, in the defendant’s absence for the afternoon. In drawing soda, he noticed that the fountain needed. re-charging. His story of the accident was as follows: “I went to the basement and filled the tank ready to charge it — started to turn in the gas, discovered that the wrench was not there with which to do it so I went upstairs to the back room and got the wrench . . . went back down to the basement and started to let [[in] the gas. It consisted of a simple affair: it was a pipe which ran from the gas cylinder down to the tank. Then it worked with a valve, with a wrench, which turned on and off in order to mix the soda gas with the water. There was an indicator on there which was supposed to tell the *208pressure we were getting. As I turned it on and off that-moved very little — perhaps two or three pounds — and I got the impression — I had had it do the same thing before ■ — ■ that there was very little gas in the cylinder. So then I opened up the valve and let it in without fear, thinking there was not much there in the tank. . . . Soon an explosion followed, the tank burst and something hit my arm and hand.” He further testified that he had worked in the store and used the carbonator before, as his previous testimony clearly indicated; that the carbonator was an old one and that the valve had always worked properly before; that the tanks were charged with about a hundred and fifty pounds pressure; that his employer did not state anything as to the condition of the carbonator before he left on the day of the accident; and that the charging of the tank was one of his (the plaintiff’s) duties.
The defendant, called as a witness by the plaintiff, testified that he had in the cellar of his store a tube of gas of a size sufficient to charge about seven tanks of soda water and with a pressure thereon of a hundred and sixty to a hundred and sixty-five pounds. His description of the method of charging the tank was as follows: “there was a tube and that was connected with the tank of soda. And I filled up the tank with ten gallons of plain water . . . then I attached this tube to the gas and turned on the gas and put in a little, and I had a rocker Under the tank and then I would shake it up back and forth, say two or three minutes, and let the gas go through the water.” In response to a question as to how he operated a valve, he said: “the indicator showed the amount of gas that was going into the tank of soda. ... I charged up a tank just about a week before that [the accident] .... I had probably seen it [in the interval after the time it was last charged], but that was the last time I touched it. . . . The first thing I do is to measure in ten gallons of water in the soda tank. And then I screw it on tight, and attach the gas, tank which has a rubber tubing to the soda water, and charge it a little at a time and then shake it. ... I use a wrench and I turn it on slowly.” To the question, “So that with one hand you shake the wrench back and forth, thus making the pressure greater or less, and then with the other hand . . . you shake the gas tank?" he replied, “I have to shut off the gas first before I shake it. ... *209I never . . . [jdo both at the same time] because the water is liable to rush up into the gas and cause an explosion into the gas tank. ... I might have Qione both at the same time] a year or two before this until I was cautioned by the soda fountain people that it was dangerous to do that and then I was cautious after that in shaking it, shutting off the gas before I shook it.” He further testified that the indicator was located on the pipe between the gas tube and the tank.
Although the testimony is not clear, it fairly appeared that the gas tank did not belong to the defendant, but had been lent to him while he was using the gas therein; that the soda tank, pipe and rocker had belonged to him for about eight years before the accident; and that he had not inspected nor examined the apparatus in the meantime except that when he charged the tank on previous occasions, the last time a week before the accident, the indicator worked properly. As a result of the accident, the soda tank was broken to pieces and the connecting pipe split.
The foregoing is the substance of all the evidence material to the issue. At the close of the plaintiff’s evidence, the defendant rested and moved that a verdict be ordered in his favor. The trial judge, subject to the defendant’s exception, refused to direct such verdict, and the jury found for the plaintiff.
The plaintiff bases his charge of negligence on the failure of the indicator to work properly, and on the danger of an explosion unless the apparatus was used in a certain and peculiar manner, claiming that knowledge of this danger was not communicated by the defendant to the plaintiff, who (he says) did not know of it.
The plaintiff was a drug clerk by business. He had been employed by the defendant on previous days. The defendant testified without contradiction that the plaintiff had been in his service during a year; he knew the apparatus for charging the tank and had used it before. There was no testimony that he was ignorant of the work to be performed, the method of performance, or of the dangers incidental thereto. Indeed, he testified that the valve was turned on and off in order to mix the gas with the water and that he did this on the day of the accident before he opened the valve which let the gas in freely. There was no testimony that he had not been warned or instructed as to the use of the apparatus, except that on the afternoon of the accident, and be*210fore the defendant left the store, nothing had been said as to the “condition of the carbonator or the tank” or indeed anything said about soda. It did not appear that the method employed for charging the tank was improper or dangerous, or such as was not in common use. Nor did it appear from previous use that there was any defect in the apparatus known to the defendant, or in existence under such circumstances as to imply that he was negligent in not knowing it. Toland v. Paine Furniture Co. 175 Mass. 476. Hill v. Iver Johnson Sporting Goods Co. 188 Mass. 75. Saxe v. Walworth Manuf. Co. 191 Mass. 338. Thompson v. National Fireworks Co. 195 Mass. 327. Childs v. American Express Co. 197 Mass. 337. Kelley v. W. D. Quimby & Co. Inc. 227 Mass. 93. Downing v. Jordan Marsh Co. 234 Mass. 559.
The mere age of apparatus like this, in the absence of evidence as to the effect of time and use, was not sufficient to fasten negligence on the defendant. The period that such apparatus can safely be used without repair or renewal was not a matter of common knowledge. Allen v. G. W. & F. Smith Iron Co. 160 Mass. 557.
The doctrine of res ipso loquitur does not apply. It is not a case where “in the ordinary course of things such an accident could not happen unless from careless construction, inspection or use attributable to the employer.” Ragolsky v. Nurenberg, 211 Mass. 575, 576. Kenneson v. West End Street Railway, 168 Mass. 1. Thompson v. National Fireworks Co. supra. Trim v. Fore River Ship Ruilding Co. 211 Mass. 593. Wadleigh v. Bumford, 229 Mass. 122. The case of Callahan v. New England Telephone & Telegraph Co. 216 Mass. 334, is distinguishable in its facts.
The motion of the defendant for a directed verdict should have been allowed, and the defendant’s exception to its refusal must be sustained. Judgment is to be entered for the defendant under G. L. c. 231, § 122.
So ordered.
