Important Data
|
Physical State; Appearance:
COLOURLESS TO WHITE CRYSTALS
OR CRYSTALLINE POWDER
.
Physical Dangers:
Chemical Dangers:
The substance decomposes
on heating
producing
nitrogen oxides
.
The substance is a strong oxidant and reacts with combustible and reducing materials.
Reacts
with
powdered metals
causing fire and explosion hazard.
Occupational Exposure Limits:
TLV: (Barium, soluble)
0.5 mg/m3
as TWA; A4; (ACGIH 2004).
MAK: (inhalable fraction) 0.5 mg/m3
Peak limitation category: II(2);
(DFG 2003).
OSHA PEL*: TWA 0.5 mg/m3 *Note: The PEL also applies to other soluble barium compounds (as Ba) except Barium sulfate.
NIOSH REL*: TWA 0.5 mg/m3 *Note: The REL also applies to other soluble barium compounds (as Ba) except Barium sulfate.
NIOSH IDLH: 50 mg/m3 (as Ba) See: IDLH INDEX
|
Routes of Exposure:
The substance can be absorbed into the body
by inhalation
and
by ingestion.
Inhalation Risk:
Evaporation at 20°C is negligible; a harmful concentration of airborne particles can, however, be reached quickly when dispersed, especially if powdered.
Effects of Short-Term Exposure:
The substance
is irritating to
the eyes
,
the skin
and
the respiratory tract
.
Exposure could cause hypokalaemia
, resulting in
cardiac disorders
and muscular disorders.
Exposure may result in death.
Effects of Long-Term or Repeated Exposure:
