PHYSICAL DANGERS:


CHEMICAL DANGERS:
The substance decomposes on burning producing toxic and corrosive fumes .

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


ROUTES OF EXPOSURE:
The substance can be absorbed into the body by inhalation, through the skin and by ingestion.

INHALATION RISK:
No indication can be given about the rate in which a harmful concentration in the air is reached on evaporation of this substance at 20°C.

EFFECTS OF SHORT-TERM EXPOSURE:
The substance is corrosive to the eyes, the skin and the respiratory tract. Inhalation of the substance may cause lung oedema (see Notes). Corrosive on ingestion.

EFFECTS OF LONG-TERM OR REPEATED EXPOSURE:

PHYSICAL
PROPERTIES

Boiling point: 231°C
Melting point: 46-50°C
Density: 0.48
g/cm3
Solubility in water, g/100 ml at 20°C: 0.23
Vapour pressure, Pa at 20°C: 27
Octanol/water partition coefficient as log Pow: 3.09

ENVIRONMENTAL
DATA

The substance is very toxic to aquatic organisms.

N O T E S

The symptoms of lung oedema often do not become manifest until a few hours have passed and they are aggravated by physical effort. Rest and medical observation is therefore essential. Substance may be transported in a molten form.
