Defective Spiking Tools

Brief Description of Incident:

The chisel point broke off of a cable spiking tool on only the second or third attempted use of this tool.  As a result the chisel point didn’t penetrate the insulation but marked the cable giving it the appearance that it had been spiked. Had the crew not noticed this they may have begun working on an energized cable.  Further investigation revealed that there have been two additional cases of the spikes on these tools deflecting sideways creating a superficial mark on the cable.

Failure of this critical tool can have significant safety consequences. All failures occurred on the AB Chance Cable Penetration Tool with a date code of 02-09-2015.
