South Metro Fire Rescue investigated a hazardous material situation in Greenwood Village Thursday afternoon after three office workers were exposed to an unknown powder while moving boxes.
The three workers who were moving boxes reported burning eyes and throats after the encountering the substance, which was between boxes, fire rescue spokesman Eric Hurst said. Investigators later determined that it was a small amount of potassium perchlorate, which is a common oxidizer used in fireworks.
The three started recovering after walking outside into fresh air, Hurst said. One was transported to the hospital as a precaution.
The call came in around 1:45 p.m. on Thursday, Hurst said. One area of the office building, which is located on South Quebec Street north of East Crestline Avenue, has been evacuated. The rest of the building is still operating.
Hurst said investigators determined that the situation was not suspicious. The substance was being cleaned up and disposed of.
