I consider sandpaper safe, yet it's also a skin irritant and I would not eat it. "Safe" does not convey anything about wearing gloves or not, and the term should not be thrown around without understanding what is meant by it. I think most people would say going outside in the sun is "safe", but most also know there is more to that than a binary "good" or "bad", "safe" or "toxic". You however seem to be using the term in binary form.
