RICHLAND, Wash. (AP) - A Hanford Nuclear Reservation contractor says another six people working at or near waste tank farms have reported symptoms believed linked to chemical vapors from the tanks.

The Tri-City Herald reports that two workers were checked out at a hospital Wednesday while four others were evaluated by Hanford's medical provider.

It was the second day in a row and the third day in the last two weeks that workers have reported symptoms linked to chemical vapors from the underground waste tanks. The newspaper says HEPA filters prevent radioactive particles from venting into the atmosphere at the tank farms, but do not capture many other nonradioactive chemicals.

The tank farm contractor, Washington River Protection Solutions, says it's collecting information to understand what happened and what can be done to prevent more occurrences.

Symptoms reported previously include coughing, burning eyes, headaches, nose bleeds and dizziness.
