Abstract: Two employees, an apprentice electrician and his helper, were repairing a wind turbine. The apprentice picked up parts and a truck at the shop. The two employees then drove to the malfunctioning wind turbine. The apprentice climbed the 61-meter-tall tower and found the problem. His assistant deenergized the system and locked out the disconnect. A few minutes later, the apprentice told his helper to reenergize the system so that he could lower the hoist to pick up tools. He brought up the tools, reached across a cabinet, and received an electric shock. He descended the tower, and his helper drove him to a hospital. He was hospitalized for 4 days and returned to work after he recovered from his injuries.
