Allways wear eye protection when grinding! after haveing piece of metal dug out of my eye recently!.
Good point, wear goggles or better yet goggles and faceshield when grinding or wire brushing. A long time back, for what ever reason I looked up at the dropped ceiling above my grinder and noticed it was growing hair. Upon closer inspection if found wire wheel wires stuck in the ceiling!!! Convinced me to wear eye protection...
