Summary
An investigation records a mechanic’s right ring-finger injury during mud-pump pony-rod replacement. Starting another pump allowed pressure to reach the pump under repair, trapping the finger between rod ends. Subsequent treatment confirmed a double fracture. The report attributes the incident to deficient communication between drill-floor representatives and mechanics.
