Executive Summary

The following charts were made from Department of Energy Occurrence Reporting and Processing System (ORPS) data.  The data are from Occurrence Reports with one or more of the following "HQ Keywords"

assigned: 01K - Lockout/Tagout (Electrical), 01M - Inadequate Job Planning (Electrical), 08A - Electrical Shocks, 08J - Electrical Near Miss, or 12C - Electrical Safety.  Statistical Process Control (SPC) techniques were applied to determine the existence of significant improving or declining trends.

A decreasing trend in overall events did occur in late 2006, dropping from 15 per month to 10 per month.  Electrical Near Misses are a primary contributor to the decrease, dropping from 9.9 per month to 4.4 per month.  The NA and EM program offices are showing decreasing trends over the past year.  It has been six months without an electrical shock at EM, a nearly significant decrease from past rates.  Electrical near misses at EM are down from 4.5 per month to stable at 0.8 per month for more than the past year.
