This аction was instituted by the widow and minor children of George T. Hinds, deceased, to recover damages for his wrongful death, which was allegеd to have been caused by the negligence of defendants. The deceased was employed as a welder by E. H. Irwin who did business as the Irwin Welding Works. The defendant, I. M. Wheadon, did business as the Allied Petroleum Company, and in connection with his business employed the defendants Chestеr Fisher and Mark Haines. On February 23, 1937, Hinds was directed by his employer to go to the premises of the Allied Petroleum Company for the purpose of performing certain welding operations which had been ordered by defendants. The defendant Fisher informed him that a steel dеhydrator tank, used in treating crude petroleum, had been prepared for the welding operation, that is, that it had been washed out and filled with water. In order to demonstrate that the tank was filled with water, Fisher ordered that the pump be started. When water flowed from a bleeder line at the top of the tank, Hinds said that it was satisfactory and began the welding operation which consisted of affixing metal brackets or straps to the outside of the dehydrator tank. The lower bracket was welded first and then Hinds commenced to work on the upper one. Shortly after Hinds commenced the final portion of the top weld, the tank exploded and he was killed. After the intrоduction of evidence by plaintiffs, *460 the trial court granted defendants’ motion for a nonsuit upon the theory that no evidence of negligence on the part of defendants had been produced. Plaintiffs appeal from the judgment of nonsuit.
Where a judgment is renderеd upon a motion for nonsuit, the court must assume that all evidence received in favor of the plaintiff relevant to the issues is true. All рresumptions, inferences and doubtful questions must be construed most favorably to the plaintiff.
(Richardes
v.
Richardes,
The defendants had an obligation, which they do not dispute, to exercise reasonable care in order to make the dehydrator tank safe for the welding operation which Hinds was ordered to рerform. Such a duty of care was required because Hinds was invited upon the premises as a business visitor to work upon the tank.
(Shanley
v.
American Olive Co.,
Defendants contend, however, that there is no evidence from which it could be found that they were guilty of negligеnce. It may be conceded that plaintiffs have not produced evidence which tends to establish specific acts of nеgligence. Negligence was pleaded generally, and plaintiffs rely upon the doctrine of
res ipso loquitur
to establish a
prima facie
case of negligence sufficiеnt to warrant submitting the case to the jury. This doctrine is applicable where a thing is shown to be under the exclusive management or cоntrol of the defendant or his servants and the accident is such as in the ordinary course of things does not happen if those who havе the management use proper care. In such cases an inference arises that the accident resulted from a want оf proper care on the part of the defendants.
(Judson
