<h2 style="white-space:nowrap">Statement of Lessons Learned</h2>
<pre>1. It is not suggested that you follow the utility locator markings as a stand-alone indicator of the location of a utility. It is imperative that the site SOTR walk-down the site and QA the map and markings.</pre>
<h2 style="white-space:nowrap">Discussion of Activities</h2>
<pre>On August 10, 2015 around 8:20 am there was a 277 volt exterior light pole circuit that was struck by a backhoe while digging to prepare an exit area for a directional bore conduit. There were no injuries and the workers immediately reported this event to their Subcontracting Officer Technical Representative (SOTR) and field supervisor. The particular light pole was tested after the strike and the results showed that there was still power to that light pole. The Jefferson Lab electrician turned the circuit off and verified that the power to that light pole was off. Prior to contractor electricians beginning the repair work, the light pole was further assessed and it was discovered that a second lighting circuit passed through the light pole base (the light pole was used as a junction point for another circuit beside the one that powered the specific light pole). This other circuit was tested and proved to be energized, so the electricians went back to the utility room and found the second lighting circuit that was inadvertently marked as ¿spare¿ on the panel board schedule (Panel schedule was updated on the spot). The second circuit was not damaged in this event. The contractor electricians then LOTO¿d both circuits 15 and 17 which then placed both lighting circuits in an electrically safe work condition. The actual repair work, to the damaged lighting circuit, has been post-poned until all digging at this location is complete.</pre>
<h2 style="white-space:nowrap">Analysis</h2>
<pre>Root Cause:
1. Failure to communicate expectations to the subcontractor to use the Jefferson Lab Basic Site Plan when marking the utilities onsite prior to the start of the work.
2. Contractor failed to conduct a thorough walk-down of the area in which they were digging. There were red lines in the general area, none were within the area to which they were about to dig.
Contributing Cause:
1. Dig Permit covered too many areas and had too many details which complicated this process. The permit is 22 pages long and covers 7 different areas. It might be best to cover less area and streamline this process as much as possible.
</pre>
<h2 style="white-space:nowrap">Recommended Actions</h2>
<pre>1. Update the dig permit to ensure that all parties are using the Jefferson Lab Basic Site Plan (BSP) as a guide, when marking utilities. Ensure that they are trained and have access to the document both on site and off site.
2. Conduct a SOTR training Meeting to re-iterate the importance of using the BSP as the master document when conducting the Walk-through.
3. The site must be walked down prior to the work beginning. This walkdown must use the BSP when conducting this walkdown as it is the most current live version of the document.
4. Although not a confirmed cause, it is imperative that the dig permits should be re-evaluated after a change occurs, that may affect the dig permit location. Once the permit is re-evaluated to ensure it¿s accuracy, it should be resigned by the permit owner.
5. Training to the utility locator company which will details expectations to include using the basic site plan, feedback requested when discrepancies.</pre>
