NAICS industry code: 213112

An employee was checking a power swivel's back-up securing line to see if it was tight enough. As he reached out to slap the line, residual stored energy released, causing the securing line to back spin. The line was attached to a turnbuckle with a safety pin in place. The safety pin spun backwards, catching and lacerating the employee's right inner elbow area and causing potential muscle damage.
