Beryllium and Beryllium Compounds (as Be)

General Description

Synonyms: Beryllium metal; Beryllium; Other synonyms vary depending upon the specific beryllium compound

OSHA IMIS code: 0360

CAS number: 7440-41-7 (elemental); Varies depending on specific beryllium compound

Monitoring Methods used by OSHA

Primary Laboratory Sampling/Analytical Method:
  • mixed cellulose ester filter (MCEF) 0.8 microns
  • maximum volume: 960 L
  • minimum volume: 480 L
  • maximum flow rate: 2.0 L/min (TWA)
  • maximum volume: 60 L
  • minimum time: 30 min
  • maximum flow rate: 2.0 L/min (ceiling)
  • maximum volume: 30 L
  • minimum time: 15 min
  • maximum flow rate: 2.0 L/min (Peak)
  • current analytical method: inductively coupled argon plasma; ICP/DCP-AES
  • method reference: OSHA ID-125G (fully validated)
  • note: If the filter is not overloaded, samples may be collected up to an 8-hour period for a time weighted average determination.

Carcinogenic classification:

EPA Inhalation Reference Concentration (RfC): 2x10-5 mg/m3

ATSDR Inhalation Minimal Risk Levels (MRLs): Not established

NIOSH IDLH concentration: 4 mg/m3

Notes on other potential health effects and hazards:

  1. Beryllium is combustible, and finely dispersed particles may form explosive mixtures (NIOSH/IPCS 1999).
  2. Occupational exposure to beryllium may be related to chronic obstructive pulmonary disease and nervous system and urinary tract cancers (Schubauer-Berigan et al. 2011).
  3. EPA RfC based on studies in workers showing beryllium sensitization progressing to chronic obstructive pulmonary disease (Kreiss 1996)
  4. Exposure to beryllium can be detected by a blood test, the beryllium lymphocyte proliferation test (Newman 2004).
