Hanford Facility Beryllium Fact Sheet

PAST OPERATIONS
Beryllium brought in facility: YES
Form of beryllium: LIQUID
Period of beryllium operations (dates): Start: 1992 End: Present
Location(s) in facility that contained beryllium materials: Tank waste

Description of beryllium activities: Low levels of beryllium may potentially be present in the liquid tank wastes.

Building monitoring data summary: None identified.
Personnel monitoring data summary: None identified.

Specify Engineering/Administrative controls used during operations: Radiological controls for tank wastes would be more than adequate to control any potential beryllium exposure.

Maximum Estimated Past Be exposure: NONE

CURRENT OPERATIONS
Building still present: YES
Beryllium present: YES
Current building occupancy/activity: Liquid waste is stored in underground tanks.

Maximum Estimated Current Be exposure: NONE

Basis for above information: Interviews with site personnel.

Comments, including any additional information needed (specify): Controls to protect workers from potential exposures to radiological materials and toxic gasses and/or vapors are more than adequate to protect workers from potential beryllium exposures. Similarly, potential exposure to beryllium in the Evaporator Building (242-A) are unlikely due to radiological controls.
