Physical Dangers:
Chemical Dangers:
Attacks many metals in presence of water.
Occupational Exposure Limits:
TLV: (as Be) 0.002 mg/m3 as TWA, 0.01 mg/m3 as STEL; A1 (confirmed human carcinogen); Intended change : 0.00005 mg/m3 as TWA; 0.0002 mg/m3 as STEL; (skin); SEN; A1 (confirmed human carcinogen); (ACGIH 2008).
MAK: sensitization of respiratory tract and skin (Sah);
Carcinogen category: 1;
(DFG 2008).
|
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 substance
is irritating to
the eyes
,
the skin
and
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
, resulting in chronic beryllium disease (cough, weight loss, weakness)
.
This substance is carcinogenic to humans.
