| 16 | +### Who may be harmed & how |
| 17 | +User - the user may receive cuts from tools while handling or sharpening them. They may also be cut by sharp edges on the workpiece. |
| 18 | + |
| 19 | +### Control measures |
| 20 | +- Training - user should not touch cutting surfaces at any time, and should be aware of potential sharp edges on the workpiece. Workpieces should be sanded where appropriate before being considered "finished." |
| 21 | +- Training - chip cleanup should be done with shop vac or dustpan and brush, not by hand. |
| 22 | +- Equipment - an emergency stop button is installed. A first aid kit is available. |
