Braley, J.
The plaintiff has no ground of exception to the ruling made at the trial. By B. L. c. 106, §§ 71, 78, 74, under which this action is brought, recovery is denied unless the death of the employee is caused either by the negligence of the employer, or of a person for whose negligence the employer is responsible. If the record is somewhat voluminous, the essential features relating to this question are easily distinguishable. The electric wires of the defendant’s system having become dangerous for want of proper insulation, new wires were to be substituted, and a gang of men, including the decedent, who was an experienced lineman, were sent out to perform the work, under the direction of a general foreman of the company. The old wires when in position rested on cross arms of six pins each, equally divided by the pole. Of these wires, the second in each group was used to carry a current of electricity of sufficient voltage to operate motors, while those remaining, consisting of two on each side nearest the pole, and two at each end of the cross arm, respectively designated as the “ pole pin ” and “ end pin wires,” were used to supply electricity for running the lights. If the current in the motor wires was not dangerous to life, each of the lighting wires was charged with an alternating current, sufficiently high to cause the death of those who might come into contact with them. The pole and end pin wires on the street side were left uncharged, but during the process of reconstruction the corresponding wires on the other side of the arm, where the decedent stood, were in operation while new wires were being substituted. In the substitution, the new wires after being raised were tied in with the old on the in- • sulators by the use of “ short tie wires,” and while doing this work the plaintiff’s husband stood on a second cross arm a little more than two feet below the first. Before tying the end pin wires, the motor wire had to be untied, and, after that had been attached to the insulator, retied. It is manifest from the testi*479mony of his fellow workmen, that, having secured the pole and end pin wires, he then had to step from the lower, over- the upper cross arm, to reach a position where he could retie the motor wire. While making the change, he apparently would have incurred no danger if the pole pin wire had been properly insulated. But about ten inches from the cross arm, and attached to this wire, over which a few turns had been taken, were the remains of a discontinued copper “ tap wire,” which had been cut off leaving a very short projecting end. On changing his position, he was obliged to step over the tap wire, which had become charged with the alternating current, when its end penetrated his body at the groin. It could have been inferred' from the different descriptions of what followed, that from the shock he either fell upon the wires or instinctively to prevent falling almost simultaneously grasped one of them, making a short circuit through which the electricity passed, causing his death. It is further stated, that when the workmen began they all knew the cause of replacement and that, while reconstruction was in progress, the defendant would supply electricity for lighting through the pole and end pin wires in use at the time of the accident. The decedent, who was a practised and skilful workman, had been informed of these general conditions, and must have been aware of the danger. During readjustment, the arrangement of the various wires, the shifting from one position to another required while fastening them, the bare wire in proximity to his person alive with electricity, were not only clearly visible, but, in the light of his general knowledge, obvious. But if these conditions are uneontroverted, the plaintiff contends that they did not embrace the remains of the tap wire. The day, however, was clear, and, even if this wire originally bright had become oxidized, resembling in color the pole pin wire, yet, from where the decedent stood on the lower cross arm, it not only was unconcealed, but was immediately within his vision. Nor is this all. He was not hurried while tying the wires, but was permitted to perform the work in his own way, with an opportunity of unrestricted observation which the dangerous environment demanded. If generally the employer, or those who under the statute stand in his place, owes a duty to an employee to warn or instruct him as to abnormal *480dangers, this duty is not violated, where from either the character of the work, or other sources, the employee is possessed of all the information which the employer could have furnished regarding such perils. Because of his previous knowledge, experience and means of ascertaining the obvious conditions under which his work must be performed, the decedent had been put in possession of all the elements of danger attendant upon his employment. The failure of the defendant, or of its foremen, who could have been found to have been entrusted with superintendence, to instruct the decedent, where for these reasons no instructions became necessary, furnished no evidence of the defendant’s negligence; and a verdict in its favor was rightly ordered.
