TYPES OF
HAZARD /
EXPOSURE
ACUTE HAZARDS / SYMPTOMS      PREVENTION      FIRST AID / FIRE FIGHTING
FIRE Flammable.  NO open flames, NO sparks and NO smoking.  Use alcohol-resistant foam, powder, carbon dioxide. 
EXPLOSION Above 25°C explosive vapour/air mixtures may be formed.  Above 25°C 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.  Use 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.  Wear 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 refer for medical attention. 
Ingestion   Do not eat, drink, or smoke during work.  Rinse mouth. Give one or two glasses 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. Then store and dispose of according to local regulations.   
EC Classification
R: 10-66; S: (2)-23-25; Note: C 
UN Classification
UN Hazard Class: 3; UN Pack Group: III 
GHS Classification
 

EMERGENCY RESPONSE SAFE STORAGE
Transport Emergency Card: TEC (R)-30S1104 or 30GF1-III.
NFPA Code: H1; F3; R0. 
Fireproof. Separated from oxidants. 

IMPORTANT DATA
Physical State; Appearance
COLOURLESS LIQUID WITH CHARACTERISTIC ODOUR. 

Physical dangers
The vapour is heavier than air. 

Chemical dangers
Reacts with oxidants. This generates fire and explosion hazard. Attacks many plastics. 

Occupational exposure limits
TLV: 50 ppm as TWA; 100 ppm as STEL; (ACGIH 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 20°C. 

Effects of short-term exposure
The substance is irritating to the eyes, skin and respiratory tract. Exposure at high levels could cause lowering of consciousness. 

Effects of long-term or repeated exposure
The liquid defats the skin.
