Important Data
|
Physical State; Appearance:
GREY
TO WHITE
POWDER.
Physical Dangers:
Dust explosion possible if in powder or granular form, mixed with air.
Chemical Dangers:
Reacts
with
strong acids
and
strong bases
forming flammable/explosive gas (hydrogen - see ICSC0001)
.
Forms shock sensitive mixtures with some chlorinated solvents, such as carbon tetrachloride and trichloroethylene.
Occupational Exposure Limits:
TLV: 0.002 mg/m3 as TWA, 0.01 mg/m3 as STEL; A1 (confirmed human carcinogen); (ACGIH 2004). Intended change 0.00002 mg/m3
Skin, Inhal.
SEN (ACGIH 2005).
MAK: sensitization of respiratory tract and skin (Sah);
Carcinogen category: 1;
(DFG 2004).
OSHA PEL: TWA 0.002 mg/m3 C 0.005 mg/m3 0.025 mg/m3 30-minute maximum peak
NIOSH REL: Ca Not to exceed 0.0005 mg/m3 See Appendix A
NIOSH IDLH: Ca 4 mg/m3 (as Be) See: IDLH INDEX
|
Routes of Exposure:
The substance can be absorbed into the body
by inhalation of its aerosol
and
by ingestion.
Inhalation Risk:
Evaporation at 20°C is negligible; a harmful concentration of airborne particles can, however, be reached quickly when dispersed.
Effects of Short-Term Exposure:
The aerosol of this substance
is irritating to
the respiratory tract
.
Inhalation of dust or fumes may cause chemical pneumonitis.
Exposure may result in death.
The effects may be delayed.
Medical observation is indicated.
Effects of Long-Term or Repeated Exposure:
Repeated or prolonged contact may cause skin sensitization.
Lungs may be affected by repeated or prolonged exposure to dust particles
, resulting in chronic beryllium disease (cough, weight loss, weakness).
This substance is carcinogenic to humans.
