Abstract:

Personal air samples collected during abrasive blasting activities inside of verification tank 60-H-TK-1C at the
Effluent Treatment Facility (ETF) initially indicated detectable levels of beryllium over the Hanford Site Chronic
Beryllium Disease Prevention Program (CBDPP) Action Level and the Occupational Safety and Health
Administration (OSHA) Permissible Exposure Level. Subcontractor workers engaged i n the blasting activity
were wearing supplied air blasting hoods and were protected from all airborne hazards including beryllium.
Upon further data review, after response actions were taken, it became apparent that sample collection errors
resulted in over-quantification of potential worker exposure.
