Probably another very relevant and worthy tip would be to use extreme caution with sharp blades and fast rotating tools.
The bench grinder in particular - if set up with a buffing wheel or Scotchbrite wheel can easily grab a knife and throw it.
If done wrong or carelessly, serious injury could be the result.
I will wear a leather glove on one hand (my left) while holding the handle firmly with my right hand. With my gloved left hand, I can control the blade better. The glove helps my hand avoid the heat from the blade as well. The thick knife blades will "hold" the heat longer than say a shovel or machete.
Of course, you don't want the blade to get too hot, but a blade on bare skin can get pretty uncomfortable even at just 140 - 150 degrees and even a few inches from where you are grinding.
I don't know about anybody else. But, when I have been using my belt sander in particular, I develop a ton of static electricity. I am very jumping when getting shocked. The flinches and reflexes can cause potential issues as well. I have always been concerned about flinching and shoving a blade into the tool, having the blade flung in my face, body, foot, etc.
I have tried grounding myself different ways. Maybe just me (????).

I also didn't mention eye protection!
