  ACUTE HAZARDS PREVENTION FIRE FIGHTING
FIRE & EXPLOSION Flammable.  Above 38°C explosive vapour/air mixtures may be formed.  NO open flames, NO sparks and NO smoking.  Above 38°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. 

   
  SYMPTOMS ACUTE HAZARDS FIRST AID
Inhalation Cough. Drowsiness. Headache. Sore throat.  Use ventilation, local exhaust or breathing protection.  Fresh air, rest. Refer for medical attention. 
Skin Dry skin. Redness.  Protective gloves. Protective clothing.  Remove contaminated clothes. Rinse skin with plenty of water or shower. 
Eyes Watering of the eyes. Redness. Pain.  Wear safety spectacles or face shield.  First rinse with plenty of water for several minutes (remove contact lenses if easily possible), then refer for medical attention. 
Ingestion Drowsiness. Headache. Nausea.    Rinse mouth. Do NOT induce vomiting. Rest. Refer for medical attention . 

SPILLAGE DISPOSAL CLASSIFICATION & LABELLING
Collect leaking and spilled liquid in sealable containers as far as possible. Wash away remainder with plenty of water. 

According to UN GHS Criteria

Physical dangers
 

Chemical dangers
The substance can presumably form explosive peroxides. Reacts with strong oxidants, acid chlorides, acid anhydrides, aluminium and copper. 

Formula: C4H10O2 / H3CCHOHCH2OCH3
Molecular mass: 90.1
Boiling point: 120°C
Melting point: -96°C
Relative density (water = 1): 0.92
Solubility in water: very good
Vapour pressure, kPa at 20°C: 1.2
Relative density of the vapour/air-mixture at 20°C (air = 1): 1.03
Flash point: 38°C
Auto-ignition temperature: 270°C
Explosive limits, vol% in air: 1.9-13.1 


EXPOSURE & HEALTH EFFECTS

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

Effects of short-term exposure
The substance and the vapour in high concentrations are irritating to the eyes, skin and respiratory tract. Exposure to very high concentrations could cause depression of the central nervous system. 

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
TLV: 50 ppm as TWA; 100 ppm as STEL; A4 (not classifiable as a human carcinogen).
MAK: 370 mg/m3, 100 ppm; peak limitation category: I(2); pregnancy risk group: C.
EU-OEL: 375 mg/m3, 100 ppm as TWA; 568 mg/m3, 150 ppm as STEL; (skin) 

ENVIRONMENT
 

NOTES
Commercial product may contain impurities which may alter toxic properties.
Check for peroxides prior to distillation; eliminate if found.
