Reacts
violently with
strong oxidants
and
reducing agents
causing fire and explosion hazard.
Reacts
violently with
strong acids
and

MAK: skin absorption (H);
Carcinogen category: 3B; BAT issued;
(DFG 2006).
EU OEL: 1 mg/m3, 0.2 ppm as TWA (skin) (EU 2006).
OSHA PEL: TWA 1 ppm (5 mg/m3) skin
NIOSH REL: TWA 1 ppm (5 mg/m3) skin
NIOSH IDLH: 200 ppm See: 98953
|
Routes of Exposure:
The substance can be absorbed into the body
by inhalation
through the skin
and
by ingestion
Inhalation Risk:
A harmful contamination of the air will be reached rather slowly on evaporation of this substance at 20°C; on spraying or dispersing, however, much faster.
Effects of Short-Term Exposure:
The substance may cause effects on the
blood
, resulting in
the formation of methaemoglobin.
Exposure could cause lowering of consciousness.
The effects may be delayed.
Medical observation is indicated.
Effects of Long-Term or Repeated Exposure:
The substance may have effects on the
blood
,
spleen
and
liver
.
This substance is possibly carcinogenic to humans.
Animal tests show that this substance possibly causes toxicity to human reproduction or development.
