A Hanford worker reported symptoms that may be related to chemical vapors from waste tanks Tuesday in the 200 East Area of the nuclear reservation.
The worker was sent to the onsite medical provider for evaluation and later released to return to work.
This was the 43rd worker to receive a medical evaluation for possible exposure to vapors this spring and summer.
The worker was outside the AN, AY and AZ Tank Farms and access there was temporarily restricted.
Never miss a local story.
Sampling of the area did not show elevated levels of chemical vapors.
Although the worker’s symptoms were not made public, typical symptoms include coughing, shortness of breath and headaches.
Workers are concerned that the chemical exposures could lead to serious long-term health problems.
The Hanford Tank Vapor Assessment Team led by the Savannah River National Laboratory was scheduled to be at Hanford through Tuesday for tours, briefings, procedure reviews, observation of work at the tank farms and meetings with workers.
Tank Farm contractor Washington River Protection solutions commissioned the national lab in South Carolina to conduct an independent review of tank vapor issues using nationally recognized experts.
