Two Hanford workers are undergoing medical evaluation after reporting odors 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 is restricted.

Industrial hygiene technicians are collecting samples in the area using direct-read instruments. Results will be shared when available.
