EINECS #: 203-869-6

  ACUTE HAZARDS PREVENTION FIRE FIGHTING
FIRE & EXPLOSION Flammable.  Above 21°C explosive vapour/air mixtures may be formed.  NO open flames, NO sparks and NO smoking.  Above 21°C use a closed system, ventilation and explosion-proof electrical equipment.  Use foam, dry powder, carbon dioxide. NO water.  In case of fire: keep drums, etc., cool by spraying with water. 

   
  SYMPTOMS ACUTE HAZARDS FIRST AID
Inhalation Cough. Sore throat. Dizziness. Headache.  Use ventilation, local exhaust or breathing protection.  Fresh air, rest. Refer for medical attention. 
Skin Redness. Pain. Dry skin.  Protective clothing. Protective gloves.  Remove contaminated clothes. Rinse and then wash skin with water and soap. 
Eyes Redness. Pain.  Wear safety goggles or face shield.  First rinse with plenty of water for several minutes (remove contact lenses if easily possible), then refer for medical attention. 
Ingestion   Do not eat, drink, or smoke during work.  Rinse mouth. 

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. Do NOT wash away into sewer. Cover the spilled material with dry earth, sand or other non-combustible material. Collect leaking and spilled liquid in sealable containers as far as possible. 

According to UN GHS Criteria

 

Transportation
UN Classification
UN Hazard Class: 3; UN Pack Group: II

PHYSICAL & CHEMICAL INFORMATION

Physical State; Appearance
COLOURLESS LIQUID. 

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

Chemical dangers
The substance can presumably form explosive peroxides. Decomposes on burning. This produces toxic gases and irritating fumes. 

Formula: C6H14O
Molecular mass: 102.20
Boiling point: 88-90°C
Melting point: -122°C
Relative density (water = 1): 0.7
Solubility in water, g/100ml at 25°C: 0.25
Vapour pressure, kPa at 25°C: 8.33
Relative vapour density (air = 1): 3.53
Relative density of the vapour/air-mixture at 20°C (air = 1): 1.2
Flash point: 21°C c.c.
Auto-ignition temperature: 188°C
Explosive limits, vol% in air: 1.3-7
Octanol/water partition coefficient as log Pow: 2.03  


EXPOSURE & HEALTH EFFECTS

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

Effects of short-term exposure
The substance is irritating to the eyes, skin and respiratory tract. Exposure at high levels could cause lowering of consciousness. 

Inhalation risk
A harmful contamination of the air will be reached rather slowly 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. 


Occupational exposure limits
 

ENVIRONMENT
 

NOTES
Check for peroxides prior to distillation; eliminate if found.
