Gotcha. Our company uses HF, 100%. It is scary shit. Period. I wouldn't want to have it in a 5 mile radius of where I live. It goes straight to your bone and attacks your bone marrow.. and eats you from the inside out.. To make it even worse, it looks and feels like water, so it can be sitting on the table and you could touch it without even knowing it... You're probably using a very diluted amount but whatever it is, make sure you're wearing proper personal protection equipment when you're using it... Otherwise get your ass to the hospital and prepare yourself for many many shots straight into your bones (without any pain killers either)..
