Sound testing kicked off recently at the Hanford Site’s Waste Treatment and Immobilization Plant as team members measured ambient sound levels throughout the plant’s facilities. The testing allows the team to verify that fire alarm volume levels meet fire codes and workers can hear alarms over ambient sounds. Ambient sound levels have changed since construction finished and commissioning activities began. Plant maintenance department team members used meters to measure ambient sound levels in multiple locations throughout the plant’s Balance of Facilities, Low-Activity Waste Facility, Analytical Laboratory and other facilities. Teams will also test at the plant’s simulator facility in Richland, Washington. Here, maintenance staff members Heather Price, left, and Fitsum Gebretatios conduct sound testing in the Analytical Laboratory.
