Two Hanford workers received precautionary medical evaluations Wednesday for symptoms potentially related to suspicious odors that could have indicated the presence of chemical vapors Tuesday near the C Tank Farm.
The odors were not reported until Wednesday, according to Washington River Protection Solutions. Both workers were released to return to work.
Although symptoms were not made public, typical symptoms include coughing and sore throats. However, workers are concerned that they could develop serious long-term health conditions.
The report brings the number of Hanford workers evaluated in recent months for possible exposure to chemical vapors to about 52.
