Hanford Chemical Exposure Safety

NV5 provided several Certified Industrial Hygienists to support Washington River Protection Solutions, the U.S. Department of Energy’s prime contractor responsible for managing 56 million gallons of radioactive and chemical waste stored in 177 underground tanks (“Tank Farms”) at the Hanford Site.

Specifically, we supported the Tank Farms Industrial Hygiene Programs Group to ensure compliance with federal, state, local, and Hanford Site requirements for industrial hygiene programs. As one example, we developed two procedures and technical basis documents related to assessing formaldehyde exposures. We also reviewed formaldehyde exposure results and the short-term risks from all identified chemicals of potential concern. We improved bench-top operations to rapidly monitor chemical vapors as a result of worker odor or exposure concerns, and we provided training.

NV5 completed the scope of work requested on time and under budget. The client was pleased with our performance, extending the original contract and then awarding us a year-long follow-on contract.
