Drill Press – When cutting holes make sure the material is secured in a Vise or Gripping Tool. Never hold the material.
Band Saw – Use the guide to push material through the blade and keep your hands from the blade. Never force material, forcing means you are trying too hard and could bind.
Scroll Saw – Move material slowly, keep your hand away from the blade.
Sander – Hold material firmly, always move against the spin.

Some materials you need to score a few times before cutting through the material. Don’t try to “man-handle” it and cut through in one swipe because the material could slip.
NEVER walk around with a knife in your hand
If you need a new blade, I will come to you 
Standing up to cut always works better than sitting down
No horse playing
Keep cap on knife when not in use
