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

PHYSICAL DANGERS:
The vapour is heavier than air.

CHEMICAL DANGERS:
The substance may polymerize under the influence of heat, oxidizers, peroxides, light. Reacts violently with oxidants. Attacks many plastics.

OCCUPATIONAL EXPOSURE LIMITS:
TLV: 1 ppm as TWA; (skin); (ACGIH 2004).
MAK: 2 ppm, 4.7 mg/m; Peak limitation category: I(2); skin absorption (H); Pregnancy risk group: IIc; (DFG 2005).
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 can be reached very quickly on evaporation of this substance at 20C.

EFFECTS OF SHORT-TERM EXPOSURE:
The substance is irritating to the eyes, the skin and the respiratory tract. The vapour irritates the eyes, the skin and the respiratory tract. The substance may cause effects on the liver and kidneys, resulting in impaired functions. Exposure above the OEL may result in death. Medical observation is indicated.

PHYSICAL PROPERTIES
Boiling point: 114C
Melting point: -48 - -52C
Relative density (water = 1): 0.97
Solubility in water: miscible
Vapour pressure, kPa at 20C: 1.54
Relative vapour density (air = 1): 1.93
Flash point: 33C c.c.
Explosive limits, vol% in air: 3.4-70
ENVIRONMENTAL DATA
The substance is toxic to aquatic organisms.
NOTES
The odour warning when the exposure limit value is exceeded is insufficient. Vapours are uninhibited and may polymerize, blocking valves and vents. Card has been partly updated in October 2005. See sections Occupational Exposure Limits, EU classification, Emergency Response.
