TYPES OF
HAZARD /
EXPOSURE
ACUTE HAZARDS / SYMPTOMS      PREVENTION      FIRST AID / FIRE FIGHTING
FIRE Flammable. Heating will cause rise in pressure with risk of bursting.  NO open flames.  Use water spray, foam, powder, carbon dioxide. 
EXPLOSION Above 60°C explosive vapour/air mixtures may be formed.  Above 60°C use a closed system, ventilation and explosion-proof electrical equipment.  In case of fire: keep cylinder cool by spraying with water. 
 
EXPOSURE   PREVENT GENERATION OF MISTS!   
Inhalation Dizziness. Drowsiness. Lethargy. Headache. Sore throat.  Use ventilation, local exhaust or breathing protection.  Fresh air, rest. Artificial respiration may be needed. Refer for medical attention. 
Skin Dry skin. Redness.  Protective gloves.  Remove contaminated clothes. Rinse and then wash skin with water and soap. Refer for medical attention . 
Eyes Redness.  Wear safety spectacles.  First rinse with plenty of water for several minutes (remove contact lenses if easily possible), then refer for medical attention. 
Ingestion Abdominal pain. Nausea. Vomiting.  Do not eat, drink, or smoke during work.  Rinse mouth. Do NOT induce vomiting. 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. Then store and dispose of according to local regulations. Personal protection: self-contained breathing apparatus.  Marine pollutant. 
EC Classification

GHS Classification
 

EMERGENCY RESPONSE SAFE STORAGE
Transport Emergency Card: TEC (R)-30GF1-III-9.

Separated from strong oxidants and strong acids. Dry. Well closed. Keep in a well-ventilated room. Store only if stabilized. 

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

Physical dangers
The vapour is heavier than air and may travel along the ground; distant ignition possible. 

Chemical dangers
The substance may polymerize due to warming. This generates fire or explosion hazard. Reacts with strong oxidants and strong acids. 

Occupational exposure limits
TLV: 50 ppm as TWA; 100 ppm as STEL; A4 (not classifiable as a human carcinogen); (ACGIH 2004).
MAK: 100 ppm, 490 mg/m³; Peak limitation category: I(2); (DFG 2004). 

Routes of exposure
The substance can be absorbed into the body by inhalation and by ingestion. 

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. The substance may cause effects on the central nervous system. 

Effects of long-term or repeated exposure
Repeated or prolonged contact with skin may cause dermatitis. The liquid defats the skin. The substance may have effects on the liver and kidneys. This may result in tissue lesions.
