<h2 style="white-space:nowrap">Statement of Lessons Learned</h2>
<pre>While using an industrial manipulator, the operator observed a spark and smoke. The machine was immediately shut down and the fire chief notified, initiating an investigation. </pre>
<h2 style="white-space:nowrap">Discussion of Activities</h2>
<pre>On the morning of May 04, 2021, during operations in the Thermal Properties Cell at INL, the manipulator operator noticed a spark and smoke. The operator immediately pushed the e-stop on the manipulator, controlled the work area and notified the Shift Supervisor. After an initial investigation the Fire Chief confirmed there was no sign of fire. It was determined that the manipulator's 90v DC power cord was pinched between the motor and the equipment guard. This resulted in a short in the conductor.</pre>
<h2 style="white-space:nowrap">Analysis</h2>
<pre>It was determined that the motor for this equipment should have been installed at a 180* rotation which would allow the power cord to hang freely, greatly reducing the pinch risk.
An extent of condition review identified that approximately half the manipulators in the area had their motors installed in a position that allow pinching of the power cable.
</pre>
<h2 style="white-space:nowrap">Recommended Actions</h2>
<pre>Manipulators that could be re-installed to reduce pinch risk were taken out of service until their motors could be reconfigured.
Notification was provided for staff to evaluate facility manipulators/equipment for similar conditions.
