Grinding is the process of removing metal by the application of abrasives which are bonded to form a rotating wheel. When the moving abrasive particles contact the workpiece, they act as tiny cutting tools, each particle cutting a tiny chip from the workpiece.

All near miss incidents shall be reported immediately as it may be a sault with the equipment or disc and not the installation of it. 3. Personnel shall ensure that all are adequately fitted to grinders. 4. When a new disc is installed it shall be tested in an enclosed box for 90 seconds to ensure that it is safe. 5. Grinders are not to be used without guards in position. |
| Lacerations to legs | 1. Can occur when working in confined spaces or areas of restricted access should the grinder kick or slip. | 1.
