PHYSICAL STATE; APPEARANCE:
COLOURLESS LIQUID , WITH CHARACTERISTIC ODOUR.

PHYSICAL DANGERS:


CHEMICAL DANGERS:
Reacts with oxidants and strong acids .

OCCUPATIONAL EXPOSURE LIMITS:
TLV not established.
MAK not established.


ROUTES OF EXPOSURE:
The substance can be absorbed into the body by inhalation of its vapour 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 and the respiratory tract , and is mildly irritating to the skin . If this liquid is swallowed, aspiration into the lungs may result in chemical pneumonitis. At high levels the substance may cause effects on the central nervous system .

EFFECTS OF LONG-TERM OR REPEATED EXPOSURE:
The liquid defats the skin.
