 =====CNSI Innovation Workshop Benchtop Grinder User Outline=====
-This guide may be found online through the Innovation Workshop and microfluidics wiki.
 ====Location====
 The benchtop grinder is located in 2448 Elings Hall next to Fume Hood #3.
 ====Safety====
-  * Part not secure and becoming a projectile
+   * Standard machine tool safety requirements apply to this tool: safety glasses, long pants and closed-toe shoes are required.  Loose clothing, jewelry, and long hair that could become entangled in the machine should be removed or secured.
-  * Thin parts (less than 0.07 in or 1.7 mm in thickness) can be pulled into the gap between the wheel and guide and cause the machine to seize.
+  * Bench grinders should NEVER be used with wood, plastic, aluminium, brass, or any non ferrous metal. Soft materials such as these can quickly build up within the wheel, causing it to become less effective, generate more heat, and even explode.
-  * Flying sparks, metal dust.
+  * Thin parts can also easily be sucked between the guide and the stone, always make sure any part is properly supported by the guide, and the gap between the guide and the stone is as small as possible. Parts pulled out of the operators hands can make deep cuts.
-  * Metal reaches a high temperature during grinding. Apply coolant while grinding and let part cool before making skin contact.
+  * Dust and sparks are often generated while grinding
-  * Keep body parts clear of grinding discs. Use a tool to hold small parts.
+  * Prevent overheating of your workpiece by cooling it periodically in water.
-  * Don’t wear bracelets, dangling articles of clothing, gloves or long sleeves while using the benchtop grinder.
+  * Never grind on the side of the grinding wheel - this can cause the wheel to break apart.
+  * Keep your hands away from all moving parts of the machine.
