HF
HF is a clear, colorless acid that is both extremely corrosive and very toxic. It
causes severe burns to the eyes, skin and respiratory tract. Pain may not be immediate
but begins as hydrogen fluoride penetrate deep through the tissues then to the bones.
Chronic exposure even to low concentrations can cause irreversible bone damage.
