Important Data
|
Physical State; Appearance:
YELLOW CRYSTALS
Physical Dangers:
As a result of flow, agitation, etc., electrostatic charges can be generated.
Dust explosion possible if in powder or granular form mixed with air.
Chemical Dangers:
May explosively decompose on shock, friction, or concussion.
May explode on heating.
Shock-sensitive compounds are formed with metals, particularly copper, lead, mercury and zinc.
On combustion, forms toxic carbon and nitrogen oxides.
Reacts vigorously with oxidants and reducing materials.
Occupational Exposure Limits:
TLV: 0.1 mg/m3 as TWA (ACGIH 2008).
MAK: skin absorption (H); sensitization of skin (Sh);
Carcinogen category: 3B
(DFG 2008).
OSHA PEL: TWA 0.1 mg/m3 skin
NIOSH REL: TWA 0.1 mg/m3 ST 0.3 mg/m3 skin
NIOSH IDLH: 75 mg/m3 See: 88891
|
Routes of Exposure:
The substance can be absorbed into the body
by ingestion.
Inhalation Risk:
Evaporation at 20°C is negligible; a harmful concentration of airborne particles can, however, be reached quickly.
Effects of Short-Term Exposure:
The substance
is mildly irritating to the eyes
Effects of Long-Term or Repeated Exposure:
Repeated or prolonged contact with skin may cause dermatitis.
The substance may have effects on the
gastrointestinal tract
,
kidneys
,
liver
and
blood
when ingested
.
