The appellant next contends there was no causal relationship between the explosion and any acts or omissions to act on the part of its employees on June 18 or 19, 1954. It contends that the acts of the deceased in using the old coal water heater for a stove, a purpose for which it was never intended, and attempting to disconnect the plugs when steam was discovered coming out of one of the openings were separate intervening acts which were the sole proximate cause of the accident. Several cases are cited in support of these contentions but they are not applicable to the situation presented here.
The jury has found the negligence of Kelly’s employee was a substantial factor in causing the accident. Since the heater was not drained, the plugging of the outlets under the circumstances here was a direct cause of the explosion and the ensuing damages. Bartlein testified that he did not drain the water out of the old heater. The fact that the intervening acts of the deceased were negligent did not make them superseding causes of the explosion as they should reasonably have been anticipated by Kelly’s employee who inserted the plugs. A discussion of the subject of intervening cause is contained in Brown v. Travelers Indemnity Co. 251 Wis. 188, 28 N. W. (2d) 306; Wenzel v. Werch, 256 Wis. 47, 39 N. W. (2d) 721; and Ryan v. Cameron, 270 Wis. 325, 71 N. W. (2d) 408.
It is further claimed that the contributory negligence of the deceased was greater as a matter of law than any negligence which could be attributed to the appellant’s employees. The comparison of the negligence of the parties is peculiarly within the province of the jury and a study of the record shows that the jury acted within proper limits. Its determination of the question must be affirmed.
There was an appeal also from the judgment against Kelly in favor of Sears. The procedure was somewhat unusual but under the circumstances was not prejudicial so far as Kelly
