  ACUTE HAZARDS PREVENTION FIRE FIGHTING
FIRE & EXPLOSION Extremely flammable. Gives off irritating or toxic fumes (or gases) in a fire.  Gas/air mixtures are explosive.  NO open flames, NO sparks and NO smoking.  Closed system, ventilation, explosion-proof electrical equipment and lighting.  Shut off supply; if not possible and no risk to surroundings, let the fire burn itself out. In other cases extinguish with dry powder, carbon dioxide.  In case of fire: keep cylinder cool by spraying with water. Combat fire from a sheltered position. 

 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 ON CONTACT WITH LIQUID: FROSTBITE.  Cold-insulating gloves. Protective clothing.  ON FROSTBITE: rinse with plenty of water, do NOT remove clothes. Refer for medical attention . 
Eyes Redness. Pain. Blurred vision.  Wear safety goggles 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   Do not eat, drink, or smoke during work.   

SPILLAGE DISPOSAL CLASSIFICATION & LABELLING
Evacuate danger area! Consult an expert! Personal protection: complete protective clothing including self-contained breathing apparatus. Ventilation. Remove all ignition sources. NEVER direct water jet on liquid.

PHYSICAL & CHEMICAL INFORMATION

Physical State; Appearance
COLOURLESS COMPRESSED LIQUEFIED GAS WITH PUNGENT ODOUR. 

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

Chemical dangers
Decomposes on burning. This produces toxic gases including nitrogen oxides. The solution is a strong base. It reacts with acid and is corrosive. Reacts with strong oxidants and organic compounds. This generates fire and explosion hazard. Attacks many non-ferrous metals and plastic.

EXPOSURE & HEALTH EFFECTS

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

Effects of short-term exposure
The substance is severely irritating to the eyes and respiratory tract. Rapid evaporation of the liquid may cause frostbite. 

Inhalation risk
A harmful concentration of this gas in the air will be reached very quickly on loss of containment. 

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
Ethylamine is available commercially also in the form of 50-70% aqueous solution (UN number: 2270).
Turn leaking cylinder with the leak up to prevent escape of gas in liquid state.
