HANFORD, WA - The Washington River Protection Solutions is working to mitigate potential sources of dangerous vapors at the Hanford Tank Farms.
As of Wednesday 17 employees had been checked out for vapors-related symptoms. On Thursday, yet another worker was sent to the site medical provider for evaluation, but that worker was later allowed to return to work.
WRPS says investigations have led them to the following potential sources of vapor emissions:
- In one farm, field investigations identified a cut in the insulation surrounding a pump pit as one potential source of vapor emissions. The cut was sealed with foam and the area was re-evaluated. Instruments no longer detect elevated levels of potential vapor-causing compounds in the local area.
- In another tank farm, investigations identified liquid in old, unused equipment that had been staged for disposal as a potential source of emissions. It has been cordoned off as a Vapor Control Zone. The liquid is being sampled and analyzed.
- Evaluations in a third farm where vapors-related symptoms were experienced found no detectable measurement of vapors-causing compounds.
WRPS says they are continuing to investigate to find other potential sources of vapors in the tank farms. They say they are encouraging employees to use additional protective gear, including respiratory devices.
