TYPES OF
HAZARD /
EXPOSURE
ACUTE HAZARDS / SYMPTOMS      PREVENTION      FIRST AID / FIRE FIGHTING
FIRE Combustible.  NO open flames.  Use powder, carbon dioxide, foam. 
EXPLOSION Above 68°C explosive vapour/air mixtures may be formed.  Above 68°C use a closed system and ventilation.   
 
EXPOSURE   PREVENT GENERATION OF MISTS!   
Inhalation Cough. Dizziness. Drowsiness. Headache. Nausea. 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. Protective clothing.  Remove contaminated clothes. Rinse skin with plenty of water or shower. Refer for medical attention . 
Eyes Redness. Pain.  Wear safety spectacles 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. Diarrhoea. Further see Inhalation.  Do not eat, drink, or smoke during work.  Rinse mouth. Give one or two glasses of water to drink. Refer for medical attention . 

SPILLAGE DISPOSAL
PACKAGING & LABELLING
Personal protection: filter respirator for organic gases and vapours adapted to the airborne concentration of the substance. Collect leaking and spilled liquid in sealable containers as far as possible. Sweep spilled substance into covered sealable containers. If appropriate, moisten first to prevent dusting. Wash away remainder with plenty of water.

Physical dangers
 

Chemical dangers
Reacts violently with strong oxidants. Attacks plastics. 

Occupational exposure limits
TLV: 50ppm as TWA; (skin); (ACGIH 2004).
MAK (2b (not established but data is available)): 50 ppm, 210 mg/m³; Peak limitation category: I(1); Pregnancy risk group: D; Skin absorption (H); (DFG 2009). 

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 not or will only very slowly be reached 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
The liquid defats the skin.
