Two Hanford workers were released back to work after undergoing medical evaluation for odors reported today outside of AW Farm. One of the workers reported symptoms while the other did not. A third worker also reported odors but declined a precautionary medical evaluation.

The employees were supporting AW Farm exhauster stack extension work and were not in an area that requires use of a supplied-air respirator. Workers were instructed to leave the area and access to the area was restricted.

Industrial hygiene technicians collected readings and samples in the area, which were below action levels. Access to the area has been restored.
