Abstract

A 21-year old man was referred to our hospital with severe respiratory distress and diffuse infiltrative shadows on chest radiograph. He had been exposed to irritant gas when polishing the inside of a stainless tank using a chemical cleaner containing hydrofluoric acid and nitric acid. He felt sick immediately after exposure and experienced respiratory distress within a few hours. He was successfully treated with intensive care including mechanical ventilation and administration of high dose methylprednisolone. Later, his illness was diagnosed as acute lung damage induced by hydrogen fluoride gas inhalation based on the findings of increased fluoride concentration in serum and urine specimen, and decreased serum calcium level.

    Occupational exposure to beryllium is well-documented to put workers' health at risk. The two principal targets of beryllium poisoning are the respiratory system and the skin. Of all beryllium compounds, beryllium fluoride complexes (including beryllium fluoride and beryllium oxyfluoride) appear to be the most toxic. As shown below, studies dating back

  • Respiratory Risks from Occupational Fluoride Exposure

    Starting in the 1930s, scientists have observed that workers exposed to airborne fluorides suffer from an elevated rate of respiratory disorders. For over 50 years, however, US government and industry scientists made repeated assurances that the allowable level of fluoride dusts and gases in industrial workplaces would not cause any
