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

PHYSICAL DANGERS:
The vapour is heavier than air and may accumulate in low ceiling spaces causing deficiency of oxygen.

CHEMICAL DANGERS:
The substance decomposes on heating producing phosgene , hydrogen fluoride and hydrogen chloride .

OCCUPATIONAL EXPOSURE LIMITS:
TLV not established.
Carcinogen category: 3B
(DFG 2008).


ROUTES OF EXPOSURE:
The substance can be absorbed into the body by inhalation.

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 20C.

EFFECTS OF SHORT-TERM EXPOSURE:
The substance irritates the eyes . The substance may cause effects on the central nervous system and cardiovascular system , resulting in narcosis and cardiac disorders.

EFFECTS OF LONG-TERM OR REPEATED EXPOSURE:
The substance may have effects on the liver.
PHYSICAL
PROPERTIES
Boiling point: 28C
Melting point: -107C
Relative density (water = 1): 1.5
Solubility in water, g/100 ml at 25C: 0.21
Vapour pressure, Pa at 25C: 14
Relative vapour density (air = 1): 6.4
ENVIRONMENTAL
DATA
Environmental Hazard placard This substance may be hazardous to the environment; special attention should be given to its impact on the ozone layer . It is strongly advised not to let the chemical enter into the environment because it persists in the environment. Avoid release to the environment in circumstances different to normal use.
N O T E S
High concentrations in the air cause a deficiency of oxygen with the risk of unconsciousness or death. Check oxygen content before entering area.
