| TYPES OF HAZARD / EXPOSURE | ACUTE HAZARDS / SYMPTOMS | PREVENTION | FIRST AID / FIRE FIGHTING |
| FIRE |
Extremely flammable. Gives off irritating or toxic fumes (or gases) in a fire.
|
NO open flames, NO sparks, and NO smoking.
|
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.
|
| EXPLOSION |
Gas/air mixtures are explosive.
|
Closed system, ventilation, explosion-proof electrical equipment and lighting.
|
In case of fire: keep cylinder cool by spraying with water. Combat fire from a sheltered position.
|
| EXPOSURE |
|
STRICT HYGIENE!
|
|
| Inhalation |
Cough. Laboured breathing. Sore throat.
|
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.
|
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 take to a doctor.
|
| Ingestion |
|
Do not eat, drink, or smoke during work.

| IMPORTANT DATA | |||
|
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: The substance decomposes on burning producing toxic gases including nitrogen oxides. The solution in water is a strong base, it reacts violently with acid and is corrosive. Reacts violently with strong oxidants and organic compounds causing fire and explosion hazard. Attacks many non-ferrous metals and plastic. OCCUPATIONAL EXPOSURE LIMITS: TLV: 5 ppm as TWA; 15 ppm as STEL; (skin); (ACGIH 2002). EU OEL: 5 ppm; 9.4 mg/m³;as TWA (EU 2000). |
ROUTES OF EXPOSURE: The substance can be absorbed into the body by inhalation. INHALATION RISK: On loss of containment, a harmful concentration of this gas in the air will be reached very quickly. EFFECTS OF SHORT-TERM EXPOSURE: The substance is severely irritating to the eyes and the respiratory tract. Rapid evaporation of the liquid may cause frostbite. | ||

Boiling point: 16.6°C Melting point: -81°C Relative density (water = 1): 0.7 (liquid) Solubility in water: miscible Vapour pressure, kPa at 20°C: 121 Relative vapour density (air = 1): 1.55 |
Relative density of the vapour/air-mixture at 20°C (air = 1): 1.66 Flash point: -17°C c.c. Auto-ignition temperature: 385°C Explosive limits, vol% in air: 3.5-14 Octanol/water partition coefficient as log Pow: -0.27/-0.08 (calculated) conductivity 7.0*10exp5 pS/m | ||
| ENVIRONMENTAL DATA | |||
|
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. Card has been partially updated in January 2008: see Occupational Exposure Limits.
