Two Hanford workers declined precautionary medical evaluation after reporting odors yesterday morning outside of SY Tank Farm in the 200-West Area.  The employees were performing excavation work to support the installation of a safety shower outside the tank farm in an area that does not require the use of supplied-air respirators.

 As a precaution, workers were instructed to leave the area.  Sampling was completed yesterday afternoon and the results were below action limits.  Access to the area was restored about 5 p.m.
