Pretty much. HF is either the gas hydrogen fluoride, or the shorthand
name for hydrofluoric acid, the solution of the gas in water (where it
dissociates into H+ and F- ions).
If HF gas is inhaled, it dissolves in the moisture of the mucous
membranes in the nose, throat and lungs, and the resulting hydrofluoric
acid acts as a severe irritant. This causes the lungs to flood as a
defence mechanism - which doesn't work - and the unfortunate victim may
'drown' through loss of lung capacity.
