3718 March 25, 1998; Updated: February 8, 2000 Johnson Controls Inc. Charles Kasch |
PAST OPERATIONS
Beryllium brought in facility: YES
Form of beryllium: SOLID
Period of beryllium operations (dates): Start: 1960 End: Late
1960s
Location(s) in facility that contained beryllium materials:
Bottom drawer of large combination safe.
Description of beryllium activities: Storage of obsolete
"dead" materials which contained beryllium.
Building monitoring data summary: None identified
Personnel monitoring data summary: None identified.
Specify Engineering/Administrative controls used during operations: Materials were packed loose in open cardboard boxes in the safe. Some were covered with grease.
Maximum Estimated Past Be exposure: NONE
CURRENT OPERATIONS
Building still present: YES
Beryllium present: NO
Current building occupancy/activity: This building is currently used for storage and has a small office area. No beryllium is believed present in the building.
1999 Study Results: Characterization of this facility was performed on March 1, 1999. Three air samples and 30 wipe samples for beryllium were taken in the building. The wipe samples were collected from the floor and horizontal surfaces throughout the building. All air samples were below the limit of detection of the method (0.001 ug/m3). All surface wipe samples were below the limit of detection of the method (0.5 ug/100 cm2).
Maximum Estimated Current Be exposure: NONE
Basis for above information: Stone and Webster report and interviews with site personnel. "1999 Study Results" summarized from Hanford Environmental Health Foundation report transmitted to RL on 4/28/99.
Comments, including any additional information needed (specify): This facility was identified based on a single memo dated June 1963 which noted beryllium storage in a safe. Because of the isolated nature and minimal exposure time (if any) expected from opening the safe and/or transporting the material in/out the facility, potential beryllium exposure is unlikely to have occurred to workers in this facility.
