Hanford nuclear site workers report possible chemical vapors

KENNEWICK, Wash. (AP) — Six workers at the Hanford nuclear reservation reported a smell that they thought might have been chemical vapors.

The Tri-City Herald reports the workers were preparing for routine electrical maintenance on Wednesday when they smelled the suspicious odor.

Tank farm contractor Washington River Protection Solutions states none of the workers experienced symptoms and all declined medical evaluations.

Workers left the area after the odor was reported. No work that would disturb waste, which can increase the chance of chemical vapors being emitted, was being done.

The last report of suspicious odors near the tank farm was on June 13, when five workers received medical evaluations after they and others smelled a suspicious odor outside the A Tank Farm
