Analysis of EFCOG Electrical Safety Charts for
December 2008
SC Program Office did achieve a decreasing trend
(greater than 10 of 11 months below average) for 08J Electrical
Near Miss. However, December came in with two reports in the
same month. A decision to baseline the chart to a zero rate is
being deferred until more data are available.
NA Program Office developed a decreasing trend
for Electrical Events overall. The past four months have been
one standard deviation below the baseline average of 5.5 per
month. A new baseline average and control limits were developed
for 08A Electrical Shocks due to its recent decreasing trend.
The new baseline is 0.5 per month, less than one-third of the
previous baseline of 1.6 per month.
EM Program Office 08A Electrical Shocks have been
set to a zero baseline following previous decreasing trends.
All other charts are stable on their current
baselines.
“A3B2C02 - Signs to stop were ignored and step
performed incorrectly” has remains in first place as the leading
cause of 08J electrical near misses over the past 12 months.
“A4B3C11 - Inadequate work package preparation” is now tied with
A3B2C02 for first place.
