- Docket 077: Manual of Analytical Methods, Beryllium - CDC
use of beryllium oxide spikes in quality control testing have been included as suggested However, inclusion of a general beryllium salts or beryllium silicate recovery discussion were not included since the focus of the research is the recovery of the most commonly encountered workplace beryllium compounds (beryllium metal and beryllium oxide)
- BERYLLIUM in Air 7704 by Field-Portable Fluorometry
beryllium concentration can be prepared by 10-fold dilution of the stock standards mentioned in the note above As with the samples, these stock standards are prepared for analysis by add-ing 0 4 mL of beryllium stock standard into 1 6 mL of detection solution (5-fold dilution) Please see Table 2
- BERYLLIUM in Surface Wipes by Field-Portable Fluorometry
beryllium concentration can be prepared by 10-fold dilution of the stock standards mentioned in the note above As with the samples, these stock standards are prepared for analysis by add-ing 0 4 mL of beryllium stock standard into 1 6 mL of detection solution (5-fold dilution) Please see Table 2

- Beryllium compounds - IDLH | NIOSH - CDC
However, the revised IDLH for beryllium compounds is 4 mg Be m3 based on being 2,000 times the OSHA PEL of 0 002 mg Be m3 (2,000 is an assigned protection factor for respirators; only the “most reliable” respirators are recommended for exposures greater than 2,000 times the OSHA PEL)
