EXPOSURE
PREVENT GENERATION OF MISTS!

Inhalation Cough. Sore throat. Unconsciousness.
Ventilation, local exhaust, or breathing protection.
Fresh air, rest. Artificial respiration may be needed. Refer for medical attention.
Skin Dry skin. Redness. Pain.
Protective gloves. Protective clothing.
Remove contaminated clothes. Rinse skin with plenty of water or shower. Refer for medical attention.
Eyes Redness. Pain.
Safety goggles.
First rinse with plenty of water for several minutes (remove contact lenses if easily possible), then take to a doctor.
Ingestion
Do not eat, drink, or smoke during work.
Rinse mouth. Rest. Refer for medical attention.
SPILLAGE DISPOSAL PACKAGING & LABELLING
Ventilation. Collect leaking and spilled liquid in sealable containers as far as possible. Absorb remaining liquid in sand or inert absorbent and remove to safe place. Do NOT wash away into sewer. Personal protection: filter respirator for organic gases and vapours.

IMPORTANT DATA
PHYSICAL STATE; APPEARANCE:
COLOURLESS LIQUID.

PHYSICAL DANGERS:
The vapour is heavier than air and may travel along the ground; distant ignition possible.

CHEMICAL DANGERS:
Reacts with strong oxidants.

OCCUPATIONAL EXPOSURE LIMITS:
TLV: 25 ppm as TWA, 40 ppm as STEL; (skin); (ACGIH 2004).
MAK: 20 ppm, 85 mg/m; Peak limitation category: I(1); Pregnancy risk group: IIc; (DFG 2005).
ROUTES OF EXPOSURE:
The substance can be absorbed into the body by inhalation of its vapour and through the skin.

INHALATION RISK:
A harmful contamination of the air will be reached rather slowly 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. Exposure could cause lowering of consciousness.

EFFECTS OF LONG-TERM OR REPEATED EXPOSURE:
The liquid defats the skin.
PHYSICAL PROPERTIES
Boiling point: 132C
Melting point: -90C
Relative density (water = 1): 0.82
Solubility in water: 2 g/100 ml
Relative vapour density (air = 1): 3.5
Flash point: 41C
Explosive limits, vol% in air: 1.0-5.5
Octanol/water partition coefficient as log Pow: 1.43
