  ACUTE HAZARDS PREVENTION FIRE FIGHTING
FIRE & EXPLOSION Extremely flammable. Gives off irritating or toxic fumes (or gases) in a fire.  Vapour/air mixtures are explosive.  NO open flames, NO sparks and NO smoking.  Closed system, ventilation, explosion-proof electrical equipment and lighting.  Use water spray, dry powder, alcohol-resistant foam.  In case of fire: keep drums, etc., cool by spraying with water. 

 PREVENT GENERATION OF MISTS! STRICT HYGIENE!  
  SYMPTOMS PREVENTION FIRST AID
Inhalation Cough. Laboured breathing. Sore throat.  Use ventilation, local exhaust or breathing protection.  Fresh air, rest. Half-upright position. Artificial respiration may be needed. Refer for medical attention. 
Skin MAY BE ABSORBED! Redness. Pain.  Protective clothing. Protective gloves.  Rinse skin with plenty of water or shower. Refer for medical attention . Remove contaminated clothes. 
Eyes Redness. Pain. Blurred vision.  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 Abdominal pain. Burning sensation. Diarrhoea.  Do not eat, drink, or smoke during work.  Rinse mouth. Do NOT induce vomiting. Give one or two glasses of water to drink. Refer for medical attention . 

SPILLAGE DISPOSAL CLASSIFICATION & LABELLING
Evacuate danger area! Consult an expert! Personal protection: filter respirator for organic gases and vapours adapted to the airborne concentration of the substance. Ventilation. Remove all ignition sources. Cautiously neutralize spilled liquid. Absorb remaining liquid in sand or inert absorbent. Then store and dispose of according to local regulations. 

According to UN GHS Criteria

ETHYLAMINE (50-70% aqueous solution) ICSC: 1482
PHYSICAL & CHEMICAL INFORMATION

Physical State; Appearance
COLOURLESS SOLUTION IN WATER WITH PUNGENT ODOUR. 

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

Chemical dangers
The substance is a strong base. It reacts violently with acid and is corrosive. Reacts violently with strong oxidants and organic compounds. This generates fire and explosion hazard. Attacks many non-ferrous metals and plastics. 

Formula: C2H5NH2 / C2H7N
Molecular mass: 45.1
Boiling point: 17°C
Melting point: -81°C
Relative density (water = 1): 0.81
Vapour pressure, kPa at 2°C: 53.3
Relative vapour density (air = 1): 1.6
Relative density of the vapour/air-mixture at 20°C (air = 1): 1.3
Flash point: -18°C c.c.
Auto-ignition temperature: 385°C
Explosive limits, vol% in air: 3.5-14 


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 substance is severely irritating to the eyes, skin and respiratory tract. 

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

Effects of long-term or repeated exposure
 


OCCUPATIONAL EXPOSURE LIMITS
TLV: 5 ppm as TWA; 15 ppm as STEL; (skin).
MAK: 9.4 mg/m3, 5 ppm; peak limitation category: I(2); pregnancy risk group: D.
EU-OEL: 9.4 mg/m3, 5 ppm as TWA 

ENVIRONMENT
The substance is harmful to aquatic organisms. 

NOTES
