Abstract: Part of a house leveling crew was under a house seeking to level its central portion. The company owner was inside the house, checking it with a level. One of the crew members was working with a metal jack rated for 8 tons. He was raising it against a seal under the house. A bar had been inserted into the jack to act as a handle, and a metal plate had been placed on top of the jack against the seal. The metal plate contacted an energized conductor, and the employee operating the jack handle was electrocuted. A second employee received an electric shock when he tried to pull the dead employee from the jack handle. The second employee was hospitalized overnight for his injury.
