IMPORTANT DATA
Physical State; Appearance Routes of exposure
COLOURLESS LIQUID, WITH CHARACTERISTIC ODOUR. The substance can be absorbed into the body by inhalation of
its vapour and by ingestion.
Physical dangers
Inhalation risk
The vapour is heavier than air and may travel along the ground;
distant ignition possible, and may accumulate in low ceiling A harmful contamination of the air can be reached rather
spaces causing deficiency of oxygen. quickly on evaporation of this substance at 20掳C.
Chemical dangers Effects of short-term exposure
Reacts with strong oxidants (e.g., peroxides, nitrates and Swallowing the liquid may cause aspiration into the lungs with
perchlorates), causing fire and explosion hazard. Attacks some the risk of chemical pneumonitis. The substance may cause
forms of plastics, rubber and coatings. effects on the central nervous system.
Occupational exposure limits Effects of long-term or repeated exposure
TLV: 600 ppm; (ACGIH 1999). Repeated or prolonged contact with skin may cause dermatitis.
MAK: 1000 ppm; 2950 mg/m 3; (1995)

Relative vapour density (air = 1): 2.5
ENVIRONMENTAL DATA
The substance is harmful to aquatic organisms.
NOTES
High concentrations in the air cause a deficiency of oxygen with the risk of unconsciousness or death.
Check oxygen content before entering area.
