Six more Hanford workers were treated for vapor exposure Tuesday after experiencing odors.

Since Thursday 4/28, 33 workers have been evaluated at the on-site medical facility. Twenty-six reported symptoms, while seven went for precautionary reasons. All but two have been released to return to work.

Workers reported odors in two separate events outside the tank farms. Access to the areas is restricted while samples are gathered and analyzed. Workers were not wearing respiratory protection, nor were they required to, since they were outside of a tank farm.
