If you use the sides of the grind stone it will weaken and make the exploding thing more likely to happen. I always use a full face sheild when grinding. One thing always stuck with me from high school when in a safety class. The instructor said that if you get an eye injury, you are lucky if you pass out becasue the pain is excruciating. I already new that from an eye injury as a child.
Tools don't hurt people, people misuse tools.
People don't get rid of or replace their worn out tools. People don't have the correct tools to do the job. People are inexperienced. People don't learn lessons until it hurts real bad. I learned all of these lessons at one time or another.
Accidents do happen, but many accidents are avoidable.
