  ACUTE HAZARDS PREVENTION FIRE FIGHTING
FIRE & EXPLOSION Highly flammable.  Vapour/air mixtures are explosive.  NO open flames, NO sparks and NO smoking.  Closed system, ventilation, explosion-proof electrical equipment and lighting.  Use water in large amounts, powder, alcohol-resistant foam, carbon dioxide.  In case of fire: keep drums, etc., cool by spraying with water. 

 STRICT HYGIENE! IN ALL CASES CONSULT A DOCTOR! 
  SYMPTOMS ACUTE HAZARDS FIRST AID
Inhalation Cough. Laboured breathing. Sore throat. Shortness of breath.  Use ventilation, local exhaust or breathing protection.  Fresh air, rest. Artificial respiration may be needed. Refer for medical attention. 
Skin Redness. Skin burns. Pain. Blisters.  Protective gloves. Protective clothing.  Remove contaminated clothes. Rinse skin with plenty of water or shower. Refer for medical attention . 
Eyes Redness. Pain. Blurred vision. Severe deep burns.  Wear safety spectacles, 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 Diarrhoea. Sore throat. Vomiting. Abdominal pain. Burning sensation. Shock or collapse.  Do not eat, drink, or smoke during work.  Rinse mouth. Do NOT induce vomiting. Refer for medical attention . See Notes. 

SPILLAGE DISPOSAL CLASSIFICATION & LABELLING
Evacuate danger area! Consult an expert! Personal protection: chemical protection suit including self-contained breathing apparatus. 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.

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. 

Chemical dangers
Decomposes on burning. This produces toxic fumes and gases (ammonia, nitrogen oxides). The substance is a weak base. Reacts with strong oxidants and strong acids. Attacks tin, aluminium and some steels. 

Formula: C4H11N / CH3CH(NH2)C2H5
Molecular mass: 73.1
Boiling point: 63°C
Melting point: -104°C
Relative density (water = 1): 0.7
Solubility in water: miscible
Vapour pressure, kPa at 20°C: 18
Relative vapour density (air = 1): 2.52
Flash point: -9°C c.c.
Auto-ignition temperature: 378°C
Octanol/water partition coefficient as log Pow: 0.74  


EXPOSURE & HEALTH EFFECTS

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

Effects of short-term exposure
The substance is corrosive to the eyes, skin and respiratory tract. 

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

Effects of long-term or repeated exposure
Repeated or prolonged contact with skin may cause dermatitis. 


Occupational exposure limits
MAK: 6.1 mg/m3, 2 ppm; peak limitation category: I(2); pregnancy risk group: D
