Outlook (Prognosis)

Hydroflouric acid is especially dangerous. The most common accidents occur with hydroflouric acid causing severe burns on the skins and hands. The burns may be extremely painful. Patients will have a lot of scarring and some loss of function of the area involved.

Persons who swallow hydroflouric acid can have a lot of damage to the inside organs, which can lead to a painful death.
