DOE Complex Electrical Event Charts
October 2008

Analysis of EFCOG Electrical Safety Charts for
October 2008
SC Program Office did achieve a decreasing trend
(10 of 11 months below average) for 08J Electrical Near Miss.
NA Program Office decreasing trend for 08A
Electrical Shocks continues. A new set of average and control
limits will be established when the data stabilize.
EM Program Office has been unstable over the past
year on 08A Electrical Shocks. There appear to be clumps of
events with long runs of zeroes in between. Two events have
occurred in the past three months, following a significantly low
period with only one event in 11 months. Still, the overall
rate is low (7 events since January 2007). There may be an
overall increasing trend developing in 08J Electrical Near
Miss. January 2008 had previously been above the UCL, and now
there have been 14 reports in the past nine months, though
October did come in at zero. If November and December stay at
baseline, it will be assumed that the January 2007 was an
isolated spike.
All other charts are stable on their current
baselines.
“A3B2C02 - Signs to stop were ignored and step
performed incorrectly” has moved into first place as the leading
cause of 08J electrical near misses over the past 12 months.
