Opinions

Appellee brought an action for personal injuries suffered when gas escaping from a pipe-line, laid by appellant, ignited from a spark from her automobile while being started in her garage. The declaration counted, upon two elements of negligence, an improper installation of the pipe and the use of an improper union or pipe connection. From a verdict and judgment in the sum of $3,000, the defendant appeals.

The gas line was laid in 1944, and consisted of several joints approximately twenty feet in length. It was laid between fifteen and eighteen inches underground. The joints were united by what is described as a "Dresser Coupling." One of these couplings pulled apart at a place beneath the garage. This dislocation was both horizontal and vertical, one end of the pipe being some three inches below the opposite end, and the separation being about three inches. The coupling remained attached to the southernmost joint. The garage was erected in the latter part of 1947, and the explosion occurred thirty-eight days thereafter. The garage was erected upon ground which sloped southward to the rear of the garage, and rested upon a solid foundation wall about the sides and rear. These walls were laid upon the surface of the ground, and were six inches thick, and their height varied from six feet at the rear to about two and a half feet at the front. The floor of the garage was constructed by filling inside this foundation wall with dirt to the level of a driveway leading to the street. The floor was finished with three concrete runners so as to accommodate two cars. The weight of the entire garage was estimated at *Page 215 eighty thousand pounds. The broken joint was beneath the dirt fill toward the front part of the fill.

Appellant's concern rises above the usual interest in displacing an adverse verdict, and seems to involve an anxiety that an affirmance of the judgment would impliedly, if not directly, proscribe the use of the "Dresser Coupling," which, he asserts, with testimonial support, has been widely used by this and other gas companies in uniting pipe sections. While we would not be privileged to share this concern as a troubling incident to a conclusion if compelled thereto by a legal necessity, we take occasion to state that neither the verdict nor our conclusions need carry such implication.

This coupling, described without technical nicety, consists of a metal sleeve or coupling body about six inches long, into which the opposing ends of pipe joints are slipped, and which is tightened by octagonal threaded nuts at each end. This action engages and progressively tightens about the pipe a rubber compound gasket, thereby sealing the line against leakage, and by pressure or compression makes a tight, though flexible, joint. Tensile strength is sought to be assured by friction produced through the tightening of the end nuts, which causes a gasket retainer to engage and hold the gaskets fast about the pipe ends. Its merit over other union devices is argued upon the ground of its flexibility which allows the pipe to slip under great pressure rather than allow a break of the pipe at the joint or at a terminal connection. To emphasize this quality of flexibility, a concession is made that it is possible for such joints to pull apart, although when properly installed they afford a tensile strength of about one thousand pounds. Its technical and popular designation as a "slip joint" conveys more than a mere implication that, if improperly applied, it would constitute a hazard not only of leakage but of actual separation.

There was conflicting testimony regarding the comparative strength and safety of other methods of coupling, *Page 216 notably by welding or the use of "ground joints" or screw couplings. Yet, the defendant procured instructions which effectively excluded comparisons with other such devices provided the Dresser Coupling was found to be reasonably safe. Taking into account their widespread use and general approval was therein authorized.

(Hn 1) It is clear that the issue of liability involves the questions whether (1) the coupling used was under the circumstances reasonably safe; (2) whether it was properly installed; (3) whether the erection of the garage was the sole proximate cause of the break; and (4) whether the erection of the garage was a reasonably foreseeable contingency against which the defendant was required to guard, or for which it was bound to make allowance. Of course, negligence in erecting the garage in the manner, and at the location, even though a concurring cause, would not of itself absolve the defendant unless it was the sole intervening cause. These alternatives were presented to the jury through proper instructions. Arguments to support the respective contentions include the observation that a leak in the pipe would not have been a serious hazard had the garage not been erected over the joint, thereby allowing the escaping gas to be accumulated and confined; that a water line of similar dimensions was laid parallel to the gas line and beneath the garage. The water line was joined with a screw coupling, and, though exposed to the same conditions, did not break or pull apart. The "Dresser Coupling" was constructed so as to remain tight against leakage, yet under emergency conditions it allowed a play or expansion by slippage equal to twice the extent to which each pipe end was inserted beyond the gasket. Just what amount of sway or deflection in the line would extend its length to the point of separation is not computed, yet the diagrams exhibited did not show any substantial sag of the line, but only, as stated above, a vertical displacement of the southern or rear section of pipe below the north or front section. *Page 217

It is noteworthy that the other joints were sufficiently secure to withstand the pressure or strain, however imposed, and that the other end of the coupling here involved remained intact. The connecting pipe joints were not similarly depressed but only the south or rear joint, which retained the coupling, was found to be three inches below the opposing joint. This supports a view that the dislocation was not due to vertical pressure from weight above the joint, but by a horizontal pull which tested its tensile strength. The more plausible theory of the defendant is that such lateral strain resulted from the weight of the rear wall and the adjacent fill, which, exerted at a point beneath the real wall, caused the southern joint to sway in an arc sufficient to cause a shortening of its length beyond the safe margin of about three inches. As stated, the diagrams exhibited do not, however, show any such deflection. The break occurred about seven feet from the front end of the garage, which, as stated, was about two and a half feet above ground, and about twelve feet from the rear wall which was about six feet high. The floor of the garage was between three and four feet above the joint.

Further elaboration of statistical data would not be helpful. The issues sharply presented are: (1) Was the erection of the garage at the place, and in the manner indicated, a reasonably foreseeable probability? If so, (2) was the pipe-line laid with commensurate care in view of such probability? (3) If such erection was not reasonably foreseeable, was it the sole and intervening cause of the break and resulting injury?

Had there been no garage, the pulling apart of the joints would have presented a simple case, although one of the defendant's instructions denied the application of the res ipsa loquiter doctrine.

Now, certain factors are without dispute. The pipe-line did pull apart, gas did escape, and as a result thereof, plaintiff was injured.
