Separately, three non-WRPS workers reported possible vapors-related symptoms today after working yesterday near AY/AZ Farms, where other workers were evacuated Tuesday. All three were taken to the site medical provider; two were released back to work. Evaluation of the third is pending.
Data collection and analysis is underway in the affected farms to understand what happened and what might be done to reduce the likelihood of future occurrences.
The presence of chemical vapors is one of the hazards of tank farm operations, and WRPS takes a conservative approach to dealing with its risksone designed to minimize potential worker exposure and provide an appropriate medical response, when necessary.
