HF is a weak acid but extremely complex binding. If you spill it on skin, it will react with any Ca in your body and FUCK.YOU.UP!
Always have plenty of water with Ca to rinse with and Ca containing “lotion”

It is also fun as you can get really interesting results. I wanted to make a coffee cup with no bottom and put some in a cup and placed the cup in Ca-water. What happened was it removed the glazing and made a cup with slight leak as liquid permiates the clay.
