TYPES OF HAZARD / EXPOSURE ACUTE HAZARDS / SYMPTOMS PREVENTION FIRST AID / FIRE FIGHTING
FIRE Flammable.
NO open flames, NO sparks, and NO smoking.
AFFF, alcohol-resistant foam, powder, carbon dioxide.
EXPLOSION Above 32C explosive vapour/air mixtures may be formed.
Above 32C use a closed system, ventilation, and explosion-proof electrical equipment.
In case of fire: keep drums, etc., cool by spraying with water.
EXPOSURE


Inhalation Cough. Dizziness. Drowsiness. Headache. Sore throat.
Ventilation, local exhaust, or breathing protection.
Fresh air, rest.
Skin Dry skin. Redness.
Protective gloves.
Remove contaminated clothes. Rinse skin with plenty of water or shower.
Eyes Redness. Pain.
Face shield, or eye protection in combination with breathing protection.
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. Give plenty of water to drink.
SPILLAGE DISPOSAL PACKAGING & LABELLING
Remove all ignition sources. 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.

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

PHYSICAL DANGERS:
The vapour is heavier than air.

CHEMICAL DANGERS:
Reacts with oxidants causing fire and explosion hazard. Attacks many plastics.

OCCUPATIONAL EXPOSURE LIMITS:
TLV: 50 ppm as TWA; 100 ppm as STEL; (ACGIH 2004).
MAK: 50 ppm, 270 mg/m; Peak limitation category: I(1); (DFG 2004).
ROUTES OF EXPOSURE:
The substance can be absorbed into the body by inhalation of its vapour.

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 irritates the eyes, the skin and the respiratory tract. Exposure at high levels may result in lowering of consciousness.

EFFECTS OF LONG-TERM OR REPEATED EXPOSURE:
The liquid defats the skin.
PHYSICAL PROPERTIES
Boiling point: 121C
Melting point: -148C
Relative density (water = 1): 0.86
Solubility in water: poor
Vapour pressure, kPa at 20C: 0.93
Relative vapour density (air = 1): 4.5
Relative density of the vapour/air-mixture at 20C (air = 1): 1.03
Flash point: 32C c.c.
Auto-ignition temperature: 380C
Explosive limits, vol% in air: 1.0-7.5
Octanol/water partition coefficient as log Pow: 2.26
ENVIRONMENTAL DATA

NOTES
Use of alcoholic beverages enhances the harmful effect. Card has been partly updated in October 2005. See sections Occupational Exposure Limits, Emergency Response.
