  ACUTE HAZARDS PREVENTION FIRE FIGHTING
FIRE & EXPLOSION Highly flammable.  Vapour/air mixtures are explosive. Risk of fire and explosion on contact with acids or oxidizing agents.  NO open flames, NO sparks and NO smoking.  Closed system, ventilation, explosion-proof electrical equipment and lighting. Do NOT use compressed air for filling, discharging, or handling. Use non-sparking handtools. Prevent build-up of electrostatic charges (e.g., by grounding).  Use water spray, powder, alcohol-resistant foam, carbon dioxide.  In case of fire: keep drums, etc., cool by spraying with water. 

   
  SYMPTOMS PREVENTION FIRST AID
Inhalation Cough. Drowsiness. Unconsciousness.  Use ventilation, local exhaust or breathing protection.  Fresh air, rest. Refer for medical attention. 
Skin Dry skin. Redness. Pain.  Protective gloves. Protective clothing.  Remove contaminated clothes. Rinse and then wash skin with water and soap. 
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 Dullness. Nausea. Drowsiness. Unconsciousness.  Do not eat, drink, or smoke during work.  Rinse mouth. 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. 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. Do NOT wash away into sewer. 

According to UN GHS Criteria

 

Transportation
UN Classification
UN Hazard Class: 3; UN Subsidiary Risks: 6.1; UN Pack Group: II 

STORAGE
Fireproof. Separated from acids and oxidants. See Chemical Dangers. Store only if stabilized. Cool. Keep in the dark.

PHYSICAL & CHEMICAL INFORMATION

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. As a result of flow, agitation, etc., electrostatic charges can be generated. 

Chemical dangers
The substance can form explosive peroxides. Reacts violently with acids and oxidants. This generates fire and explosion hazard.

EXPOSURE & HEALTH EFFECTS

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

Effects of short-term exposure
The vapour is irritating to the eyes, skin and respiratory tract. The substance may cause effects on the central nervous system. This may result in lowering of consciousness. 

Inhalation risk
No indication can be given about the rate at which a harmful concentration of this substance in the air is reached on evaporation at 20°C. 

Effects of long-term or repeated exposure
The substance defats the skin, which may cause dryness or cracking. 


OCCUPATIONAL EXPOSURE LIMITS
 

ENVIRONMENT
 

NOTES
Check for peroxides prior to distillation; eliminate if found.
The relation between odour and the occupational exposure limit cannot be indicated.
Environmental effects from the substance have not been investigated.
An added stabilizer or inhibitor can influence the toxicological properties of this substance, consult an expert.
