  ACUTE HAZARDS PREVENTION FIRE FIGHTING
FIRE & EXPLOSION Flammable.  Above 45°C explosive vapour/air mixtures may be formed.  NO open flames, NO sparks and NO smoking.  Above 45°C use a closed system, ventilation and explosion-proof electrical equipment.  Use water spray, powder, alcohol-resistant foam, carbon dioxide.  In case of fire: keep drums, etc., cool by spraying with water. 

 AVOID ALL CONTACT!  
  SYMPTOMS ACUTE HAZARDS FIRST AID
Inhalation Dizziness. Drowsiness. Headache.  Use ventilation, local exhaust or breathing protection.  Fresh air, rest. Refer for medical attention. 
Skin MAY BE ABSORBED! Dry skin. Further see Inhalation.  Protective gloves. Protective clothing.  Remove contaminated clothes. Rinse skin with plenty of water or shower. Refer for medical attention . 
Eyes Redness.  Wear safety goggles 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. Nausea. Vomiting. Weakness. Unconsciousness. Further see Inhalation.  Do not eat, drink, or smoke during work.  Rinse mouth. Do NOT induce vomiting. Refer for medical attention . 

SPILLAGE DISPOSAL CLASSIFICATION & LABELLING
Personal protection: filter respirator for organic gases and vapours adapted to the airborne concentration of the substance. Do NOT let this chemical enter the environment. Ventilation. 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.

EXPOSURE & HEALTH EFFECTS

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

Effects of short-term exposure
The vapour is mildly irritating to the eyes. The substance may cause effects on the bone marrow and central nervous system. The substance may cause effects on the blood at high levels. This may result in lesions of blood cells and kidney impairment. Exposure far above the OEL could cause unconsciousness. 

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

Effects of long-term or repeated exposure
The substance defats the skin, which may cause dryness or cracking. The substance may have effects on the bone marrow and blood. This may result in lesions of blood cells and kidney impairment. May cause toxicity to human reproduction or development. 


Occupational exposure limits
TLV: 0.1 ppm as TWA; (skin); BEI issued.
MAK: 4.9 mg/m3, 1 ppm; peak limitation category: II(8); skin absorption (H); pregnancy risk group: B.
EU-OEL: 1 ppm as TWA; (skin) 

ENVIRONMENT
The substance is harmful to aquatic organisms. 

NOTES
Check for peroxides prior to distillation; eliminate if found.
Health effects of exposure to the substance have not been investigated adequately.
Its effects are deduced from those of similar substances.
