<h2 style="white-space:nowrap">Statement of Lessons Learned</h2>
<pre>Ensure that hand-held tools have expended all their residual energy before setting them down.</pre>
<h2 style="white-space:nowrap">Discussion of Activities</h2>
<pre>During a roofing project at Los Alamos National Laboratory Technical Area-3, Building 422, involving the use of a hand-held grinder; a roofer, who was wearing all the appropriate Personal Protective Equipment (including knee pads), sustained a laceration slightly above his right knee. According to the roofer, he had finished cutting off a rivet that had been securing some metal fascia. He released the grinder¿s power switch and was setting it down when he cut through his Tyvek coveralls and jeans. The roofer told his foreman of the incident and was asked if he wanted to go Occupational Medicine for evaluation. The roofer indicated that he was OK and continued to work the rest of the day. </pre>
<h2 style="white-space:nowrap">Analysis</h2>
<pre>The roofer did not notice the laceration until he went home and was removing his jeans. Since the injury was in the approximate location and was the size of the cut material it was evident that the injury was the result of the grinder¿s residual motion.</pre>
<h2 style="white-space:nowrap">Recommended Actions</h2>
<pre>Below are the consequences of the above event. They are provided for information and discussion purposes only.
The roofer immediately called his foreman and was taken for to the hospital where five sutures were applied to close the 1-inch long laceration. The medical provider said the laceration did not bleed due to the fact that it was cauterized immediately by the extreme heat of the grinding wheel. </pre>
<h2 style="white-space:nowrap">JLab Preventive Measures</h2>
<pre>(Jefferson Lab¿s Subject Matter Expert has provided the following recommendations.)
With any compressed air power tool (once work with the tool is complete)
1. Turn off the power source.
2. With tool in hand, slowly squeeze the trigger to release any remaining air pressure from the tool.
3. Disconnect the air hose from the tool. And, if applicable, disconnect air hose from the power source.
4. Properly store the air hose and tool.
Always use tools in accordance with Jefferson Lab's and manufacturer's requirements.
See EH&S Manual Chapter 6120 Portable Hand Tool Safety and its appendices.
