An EMS helicopter landed on a dirt road near a seafood processing plant. He was to pick up a worker who had suffered a major back injury from a falling 500' block of ice. His takeoff path was obstructed by telephone wires. He elected to takeoff beneath the wires rather than to try to climb over them. He had 35 hours in this particular model aircraft. He misjudged the height of his tail rotor which cut the lowest of 3 phone wires. A 1/4 X 1/8 nick was made in 1 tail rotor blade. He was unaware of the wire strike until advised by radio as he approached his destination. He elected to proceed to the hospital with the patient rather than divert to an airport even though he said such diversion would have been the prudent thing to do.
