The plaintiffs brought these actions for personal injuries, alleging negligence and breach of warranty, against Allied Chemical Corporation (Allied) a vendor of acids. and against Plax, the manufacturer of the containers of the acids. The plaintiff Madeline was employed as an etcher by North American Electronics Corp. (Electronics) the buyer of the acids. Verdicts were directed for both Allied and Plax on the warranty counts. The negligence counts were submitted to the jury, who returned verdicts for Plax and for the plaintiffs against Allied. The judge, subject to exception, entered verdicts for Allied under leave reserved. The exceptions argued are to the action of the judge in directing verdicts for Allied and Plax on the warranty counts and in entering verdicts for Allied on the negligence counts.
We review and summarize the evidence under the rule stated in Kelly v. Railway Exp. Agency, Inc. 315 Mass. 301, 302. Tanguay v. Wood Conversion Co. 347 Mass. 530, 531. Almost all of the evidence came from witnesses called by the plaintiffs, including employees of Allied. Since Electronics' organization in 1959 to the date of the accident on September 13, 1961, it had bought its liquid chemicals from Allied. Among the chemicals were hydrofluoric and nitric acids. Both are extremely corrosive. Hydrofluoric acid, for example, "will attack practically everything, glass, steel, all types of metal." If a sufficient quantity should leak out of a bottle in transit, "it would burn a hole right through the freight car." Each of the two acids when shipped by Allied was contained in one gallon bottles or jugs made of polyethylene, commonly called plastic. The jugs were made by Plax pursuant to specifications given by Allied. The buyer of the acids paid a deposit on the jugs, which were returnable to Allied, whose name was impressed in the polyethylene. Polyethelene is a strong, flexible, acid-resistant synthetic material. It retains these characteristics for at least ten years and permits the manufacture of a seamless container. The jugs in which the hydrofluoric and nitric acids were sold to Electronics were closed by a *327 solid nonvented polyethelene screw-on cap within which there was a thin solid polyethelene disc. This type of cap prevents leakage or spillage of the corrosive acids if the jug is turned over. It is a good and safe cap for uncontaminated hydrofluoric acid or nitric acid. It will hold them in the bottle. The jug which exploded had a nonvented cap.
Allied also shipped some chemicals in jugs with vented caps. It sold hydrogen peroxide to Electronics in either glass or polyethelene bottles with a vented cap. The reason is that hydrogen peroxide decomposes or breaks down rapidly if contaminants are added, creating great quantities of gas which must be released if an explosion is to be avoided. A vented cap was used to release from the jug the gas resulting from the contamination of hydrogen peroxide. Neither hydrofluoric acid nor nitric acid alone generates gas under normal conditions, nor do they when mixed together. If either alone, or a mixture of the two, however, is added to hydrogen peroxide, there is quickly liberated a gas which if confined in a jug would cause the jug to explode. A vented cap differs from an unvented cap in that it has a hole in the top and a slitted plastic washer inside. The slit is closed until the pressure from gas is built up. When the pressure is sufficiently built up, the slit in the washer opens and releases it. When the vent is closed, there is probably no chance of the liquid spilling.
Madeline's job involved in part the use of a prescribed mixture of hydrofluoric and nitric acids to etch parts used in the manufacture of a device produced by Electronics. The parts were then washed in running water and dipped in hydrogen peroxide. The hydrofluoric and nitric acids were mixed in a plastic bottle which was then placed under the sink in the etching room. When new, hydrofluoric acid and nitric acid are visually indistinguishable from distilled water; all are clear. It was customary in the electronics industry to use plastic bottles for mixing acids. On the day of the accident, September 13, 1961, Madeline mixed hydrogen peroxide and distilled water, put the cap on the *328 bottle, placed the bottle under the sink, and started to leave the room when the explosion took place. She did not mix any hydrogen peroxide with hydrofluoric acid. Although she did not know what would happen if she did mix them, she knew that she was not supposed to mix them. She had been told to "be careful." She was not sure that the bottle which blew up was the bottle in which she had put the hydrogen peroxide. The identity of the person who mixed the contents of the jug which exploded was never ascertained.
The explosion did not cause the jug to disintegrate or fragment. The cap, which was the strongest part of the unit, remained intact. There were vertical splits or ruptures around the jug caused by the pressure of the gas within it which resulted in the liquid being forcefully expelled.
There was no serious dispute that the probable cause of the explosion was the mixture and containment of hydrogen peroxide and an acid in an unvented plastic bottle. The atmospheric conditions which otherwise might conceivably have accounted for the explosion were not shown to have existed. The experts were agreed that if the plastic bottle containing the mixture had had a vented cap there would have been no explosion.
Allied's representative knew that its jugs were being used to mix and store acids at Electronics, that the employees in the etching room were not skilled chemists, that hydrogen peroxide was kept in the etching room, and that there was a possibility that the acids in the same room might be in contact with it. He testified that two safety meetings were held at which these matters were pointed out to Electronics' personnel; that the second was held four weeks before the accident.
The purchasing director and plant superintendent of Electronics conceded that there had been a safety meeting of Allied and Electronics people but stated that he did not attend. He knew that there were four or five chemicals on the premises some of which, when mixed, generated gas; that some of the bottles had venting caps, and that any *329 bottle containing a chemical which will generate gas should have a vent cap to release the gas. He knew that hydrogen peroxide was treated differently because it had to be vented. He had never received instructions from Allied not to reuse the bottles for mixing acids. Madeline's immediate supervisor at Electronics had never received instructions from Allied not to reuse Allied's jugs for mixing acids or storing mixed acids. He knew that jugs of hydrofluoric acid, nitric acid and hydrogen peroxide were among the chemicals kept in the etching room and that plastic jugs of acid were kept under the sink. He knew that there was a difference in the caps used on jugs to mix things and that some caps were vented. He knew that some acids when confined generate gas and that if the gas is not released through a venting hole "something can happen."
The jugs received by Electronics from Allied bore labels identifying the chemical contents. The labels on the acid bottles cautioned to "loosen bottle closures carefully" or "Open carefully to relieve possible internal pressure before completely removing closure." They specified the hazards of poison or burns and prescribed antidotes and precautions against spillage. On the day of the accident the labels on the bottles in the etching room and another room were "practically illegible."
On the evidence, the judge was right in entering verdicts for Allied on the negligence counts under leave reserved. "[A] person who owns or controls an instrumentality which he knows, or with reasonable care should know, is dangerous in its nature or is in a dangerous condition and who disposes of it in a manner that he foresees, or in the exercise of reasonable care ought to foresee, will probably carry that thing into contact with some person, known or unknown, who will be ignorant of the danger, owes a legal duty to every such person to use reasonable care to prevent injury to him." Mann v. Cook, 346 Mass. 174, 176-177. Carter v. Yardley & Co. Ltd. 319 Mass. 92, 96. If Allied had not been aware of the loose safety practices at Electronics, this obligation would have been fully met. Allied had shipped each of the *330 chemicals in a specially manufactured container closed by a cap specially and adequately designed to guard against the hazards which might reasonably be anticipated from the particular chemical during shipment and storage prior to use. We think Allied could reasonably have relied on Electronics thereafter to take proper safety precautions and to instruct its own employees in the proper technique to be used in handling these dangerous acids. "It was the ... [Electronics'] common law duty to furnish ... [its employees] safe materials with which to work or to warn ... [them] of any dangers of which ... [it] knew or ought to have known and which were not reasonably obvious to ... [them]." Taylor v. Newcomb Baking Co. 317 Mass. 609, 611. See Peacock v. Ambassade Realty Co. 336 Mass. 115, 118.
There remains, however, the question whether any additional duty was placed on Allied by its knowledge that the bottles were being used by Electronics to mix acids and to store mixed acids in the etching room. The duty to exercise reasonable care includes a duty to warn of danger, if "the person on whom that duty rests has some reason to suppose a warning is needed." Carney v. Bereault, 348 Mass. 502, 506. It does not appear from the evidence that Allied failed to perform this duty. The evidence indisputably shows that at Allied's suggestion, a safety meeting was held between Allied's and Electronics' supervisory personnel prior to the accident. There was testimony that at the meeting it was pointed out that (a) the bottles designed for hydrofluoric acid should be returned after use, but (b) if they were to be used to contain any other acid, it should be done under a certain condition, and (c) hydrogen peroxide very specifically should not come in contact with any strong acids. This testimony was left entirely uncontradicted as to points (b) and (c) and was not directly contradicted as to point (a). The affirmative of the issue was on the plaintiffs, see Cadogan v. Boston Consol. Gas. Co. 290 Mass. 496, 499. There was no evidence of failure to warn of the danger of which Allied had become aware. It was not Allied's responsibility to *331 compel the attendance of Electronics' personnel at the meeting or to enforce safety regulations in Electronics' plant, or to train Electronics' employees in the etching room.
The breach of warranty counts may be dealt with summarily. It was correct to direct verdicts for both Allied and Plax because there was no privity of contract between Madeline and either of them. Kennedy v. Brockelman Bros. Inc. 334 Mass. 225, 227. Sullivan v. H.P. Hood & Sons, Inc. 341 Mass. 216, 223. The Uniform Commercial Code, G.L.c. 106, § 2-318, dispenses with this requirement only in the case of a "natural person who is in the family or household of ... [the] buyer or ... a guest." None of these relationships exists here.
The plaintiffs' exceptions with respect to Monsanto are dismissed. All their other exceptions are overruled. Judgments are to be entered for the defendants.
So ordered.
