Important Data
|
Physical State; Appearance:
COLOURLESS LIQUID
, WITH CHARACTERISTIC ODOUR.
Physical Dangers:
Chemical Dangers:
The substance can presumably form explosive peroxides in contact with air.
Reacts
violently with
strong oxidants
.
Attacks many metals forming flammable/explosive gas (hydrogen - see ICSC 0001).
Occupational Exposure Limits:
TLV: 100 ppm; skin (ACGIH 1999).
TLV: 150 ppm; (STEL) (skin) (ACGIH 1999).
MAK: 50 ppm, 310 mg/m3
Peak limitation category: I(1); Pregnancy risk group: D;
(DFG 2008).
OSHA PEL: TWA 100 ppm (600 mg/m3) skin
NIOSH REL: TWA 100 ppm (600 mg/m3) ST 150 ppm (900 mg/m3) skin
NIOSH IDLH: 600 ppm See: 34590948
|
Routes of Exposure:
The substance can be absorbed into the body
by inhalation of its vapour,
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.
Effects of Short-Term Exposure:
The vapour
irritates
the eyes
and
the respiratory tract.
The substance may cause effects on the central nervous system
, resulting in narcosis.
Effects of Long-Term or Repeated Exposure:
The liquid defats the skin.
