Arm injury caused while loosening bolt on WTG

What happened?

A technician was loosening a bolt with a wrench on an offshore wind turbine generator (WTG).

The technician lost control of the wrench and slipped.

The technician's right elbow area caught a sharp edge of the busbar box and caused a cut.

The socket wrench provided did not have sufficient grip for handling bolts secured with thread locking compounds.

Sharp edges did not have to appropriate edge protection to prevent injury.

Ensure the socket wrench provides a grip designed for handling bolts secured with thread locking compounds.

A wrench with ratcheting mechanisms or an impact wrench will offer more control and reduce the risk of slippage.

Apply edge protection on identified sharp edges.

Are you using the most appropriate tool for the task?
