Two Hanford workers declined precautionary medical evaluation this morning after reporting odors at AP Farm. Neither reported symptoms. The employees were monitoring farm conditions from the AP Farm instrument building 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 gathered samples in the area. None of the monitoring and sampling results exceeded the action level for any chemical detected. Access to the area has been restored.
