To All -
As stated above an electric shock can cause a person to stop breathing by
contracting the lung muscles. The important thing to remember is that a
person who is unconcious and not breathing after receiving an electric shock
can somtimes be revived by CPR if immediate action is taken. Disconnect the
electric circuit. Carefully remove the victim from contact with wires and
start the CPR. Do not wait for medical help.
