Important Data
|
Physical State; Appearance:
WHITE
CRYSTALS
.
TURNS PINK ON Exposure TO AIR, LIGHT OR ON CONTACT WITH IRON.
Physical Dangers:
As a result of flow, agitation, etc., electrostatic charges can be generated.
Chemical Dangers:
Reacts
with
strong oxidants
ammonia
and
amino compounds
, causing fire and explosion hazard.
Occupational Exposure Limits:
TLV: 10 ppm as TWA; 20 ppm as STEL; A4; (ACGIH 2003).
EU OEL: 10 ppm, 45 mg/m3, as TWA; (skin) (EU 2000).
OSHA PEL: none
NIOSH REL: TWA 10 ppm (45 mg/m3) ST 20 ppm (90 mg/m3)
NIOSH IDLH: N.D. See: IDLH INDEX
|
Routes of Exposure:
The substance can be absorbed into the body
by inhalation of its aerosol,
through the skin
and
by ingestion.
Inhalation Risk:
A harmful contamination of the air will not or will only very slowly be reached on evaporation of this substance at 20°C
; on spraying or dispersing, however, much faster.
Effects of Short-Term Exposure:
The substance
is irritating to
the eyes
,
the skin
and
the respiratory tract
.
The substance may cause effects on the
blood
, resulting in
formation of methaemoglobin.
The effects may be delayed.
Medical observation is indicated.
Effects of Long-Term or Repeated Exposure:
In rare cases,
repeated or prolonged contact may cause skin sensitization.
