Analysis of EFCOG Electrical Safety Charts
for December 2009
The overall number of Electrical Events
reports was close to the Upper Control Limit for September with
18 reports.
The data since have returned closer
to baseline, but the past five months have been above average.
Another two months above average
will be a significant increasing trend.
Electrical Shocks (08A) for All DOE have
been above average for more than seven months in a row.
This is a significant increasing
trend.
A new baseline average and control
limits will be developed when the data stabilize.
SC Program Office charts are stable.
Electrical Near Miss (08J) did come
in close to the UCL in November, and another month similar to
this in January will cause a trend to be declared.
NA Program Office 08A Electrical Shocks
have a significant increasing trend with November above the UCL,
and both October and November more than two standard deviations
above average.
December did return to closer to baseline.
A new baseline average and control
limits will be established if the data stabilize higher than the
existing baseline.
NA 08J Electrical Near Misses were close to
the UCL in November.
Another month similar to this in
December or January will cause a trend to be declared.
EM Program Office 08J Electrical Near Miss
Chart is one month away from an increasing trend.
The past three of four months have
been one standard deviation above average.
All other charts are stable on their
current baselines.
Check of Work was Less than Adequate
(A3B1C01) remains the leading cause of 08J Near Miss events.
A3B1C03 - Incorrect performance due
to mental lapse and A3B2C05 - Situation incorrectly identified
or represented resulting in wrong rule used are now tied with
A3B1C01 for the leading cause, each with 5 events over the past
12 months.
