The plaintiff’s husband voluntarily undertook to help in a work of manifest danger. That alone would bar a recovery. But in addition to this, it appears that the primary cause of the accident was the slipping of the pipe out of the deceased’s hands, thus throwing the weight on him and knocking him into the vat. If this was not the result of his own carelessness in handling the pipe, it certainly did not show any negligence on the part of defendants.

Judgment affirmed.
