TYPES OF
HAZARD /
EXPOSURE 		ACUTE HAZARDS / SYMPTOMS      PREVENTION      FIRST AID / FIRE FIGHTING
FIRE Highly flammable.  NO open flames, NO sparks and NO smoking.  Use powder, AFFF, foam, carbon dioxide. 
EXPLOSION Vapour/air mixtures are explosive.  Closed system, ventilation, explosion-proof electrical equipment and lighting. Do NOT use compressed air for filling, discharging, or handling. Use non-sparking handtools.  In case of fire: keep drums, etc., cool by spraying with water. 
 
EXPOSURE      
Inhalation Dizziness. Drowsiness. Lethargy. Headache. Nausea. Weakness. Unconciousness.  Use ventilation, local exhaust or breathing protection.  Fresh air, rest. Refer for medical attention. 
Skin Dry skin. Redness. Pain.  Protective gloves.  Remove contaminated clothes. Rinse and then wash skin with water and soap. Refer for medical attention . 
Eyes Redness. Pain.  Wear safety goggles, 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 Abdominal pain. Further see Inhalation.  Do not eat, drink, or smoke during work.  Rinse mouth. Do NOT induce vomiting. Rest. Refer for medical attention . 

SPILLAGE DISPOSAL
 		PACKAGING & LABELLING
Consult an expert! Personal protection: filter respirator for organic gases and vapours adapted to the airborne concentration of the substance. Remove all ignition sources. Do NOT wash away into sewer. Do NOT let this chemical enter the environment. 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
Symbol: F, Xn, N; R: 11-38-48/20-62-65-67-51/53; S: (2)-9-16-29-33-36/37-61-62 
UN Classification

GHS Classification
 

EMERGENCY RESPONSE SAFE STORAGE
Transport Emergency Card: TEC (R)-30S1208.
NFPA Code: H1; F3; R0.  		Fireproof. Separated from strong oxidants. Well closed. 

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

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

Chemical dangers
Reacts with strong oxidants. This generates fire and explosion hazard. Attacks some plastics, rubber and coatings. 

Occupational exposure limits
TLV: 50ppm, 176mg/m³ as TWA; (skin); BEI issued; (ACGIH 2004).
MAK: 50 ppm, 180 mg/m³; Peak limitation category: II(8); Pregnancy risk group: C; (DFG 2004). 

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

Inhalation risk
A harmful contamination of the air can be reached rather quickly on evaporation of this substance at 20°C. 

Effects of short-term exposure
The substance is irritating to the skin. If this liquid is swallowed, aspiration into the lungs may result in chemical pneumonitis. Exposure at high levels could cause lowering of consciousness. 

Effects of long-term or repeated exposure
Repeated or prolonged contact with skin may cause dermatitis. The substance may have effects on the central nervous system and peripheral nervous system. This may result in polyneuropathy. Animal tests show that this substance possibly causes toxic effects upon human reproduction.
