Longmont emergency manager Dan Eamon tells the Daily Times-Call the woman was injured Saturday by a chemical reaction while she was diluting ferric chloride. The chemical is often used for water treatment and to etch metal.
Eamon says there was no explosion, although that had been the initial report as police, fire and hazardous materials units went to the scene.
Front Range Community College spokesman John Feeley says the building where the accident happened did not have to be evacuated, but the jewelry studio closed and its occupants left while emergency crews checked the situation.
