N2 Fitting and Machining Theory|Hands-On! 11


• Te wheel must not be worn down to within 10 mm of the paper washers on the sides and the side flanges should be at least one third of the wheel’s outer diameter.


• When you are ready to start grinding and are wearing all the required safety gear such as safety glasses and gloves, stand to one side until the wheel reaches operating speed before you start.


• Make sure you have received sufficient instruction in the operation of the particular machine, including, in particular, where to turn it off in a hurry before you start grinding with it.


Caution Te best way to prevent accidents is to concentrate on what you are doing.


Accidents


Accidents can usually be avoided as they are caused mostly by a combination of unsafe conditions and unplanned actions by people doing things for which they are either not trained or not capable of doing properly. Unsafe actions by workers are amajor cause of concern.


Examples of unsafe actions are: • adjusting or lubricating a machine that is in operation • working at an unsafe, too high speed, beyond the safe maximum limit • not wearing the required minimum safety protective clothing for a specific job • working on a machine for which you are not trained • working on a machine or with equipment without the necessary permission


• bypassing necessary safety devices such as safety switches which would stop the machine if it was over loaded, when a guard is open or not in place


• distracting other workers when they are busy working by clowning around, swearing at them, insulting them or their family or friends or teasing them


• running in the workshop with sharp objects in your hands or pockets • using your hands or feet in place of available equipment


• working in an area marked for other purposes such as a thoroughfare, meant for the movement of people and goods


• working in an unsafe, unsuitable area where construction is in progress or that has been condemned or deemed unsafe due to lack of ventilation, poor lighting or and other reason


• the worker is not well, not sober or under the influence of drugs


• wearing unsuitable or loose hanging clothing that could be caught on objects like handles, vices or moving machine parts when the worker passes by.
