Incident date: 2015-10-04
NAICS industry code: 213112

Two shop employees were in the process of tearing down a 1250 Ton Slip Type Elevator (STE) and were pulling the carriers and slips out of the STE.  While removing one of the carriers from the slip, utilizing the overhead crane, the entire slip assembly (carrier, slip, and slip hanger) began to rise out of the tool.  As the slip hanger rose the IP reached in to remove it when the slip suddenly released from the carrier pushing the slip hanger back into position.  The IP's finger was caught between the slip hanger and the timing ring of the STE amputating the tip of his left index finger midway up the fingernail.
