| UN #: 1079
|EC Number: 231-195-2
|ACUTE HAZARDS||PREVENTION||FIRE FIGHTING|
|FIRE & EXPLOSION||Not combustible. Heating will cause rise in pressure with risk of bursting.||In case of fire in the surroundings, use appropriate extinguishing media. In case of fire: keep cylinder cool by spraying with water. NO direct contact with water. Combat fire from a sheltered position.|
|STRICT HYGIENE! IN ALL CASES CONSULT A DOCTOR!|
|Inhalation||Cough. Shortness of breath. Sore throat. Laboured breathing. See Notes.||Use ventilation, local exhaust or breathing protection.||Fresh air, rest. Artificial respiration may be needed. Refer for medical attention.|
|Skin||ON CONTACT WITH LIQUID: FROSTBITE.||Cold-insulating gloves.||ON FROSTBITE: rinse with plenty of water, do NOT remove clothes. Refer for medical attention .|
|Eyes||Redness. Pain.||Wear safety goggles, face shield or eye protection in combination with breathing protection.||Rinse with plenty of water for several minutes (remove contact lenses if easily possible). Refer for medical attention.|
|SPILLAGE DISPOSAL||CLASSIFICATION & LABELLING|
|Evacuate danger area! Consult an expert! Personal protection: complete protective clothing including self-contained breathing apparatus. Ventilation. NEVER direct water jet on liquid.||

|OCCUPATIONAL EXPOSURE LIMITS|
TLV: 0.25 ppm as STEL; A4 (not classifiable as a human carcinogen).
MAK: 2.7 mg/m3, 1 ppm; peak limitation category: I(1); pregnancy risk group: C.

|The substance is harmful to aquatic organisms.|
|Depending on the degree of exposure, periodic medical examination is suggested.
The symptoms of asthma often do not become manifest until a few hours have passed and they are aggravated by physical effort.
Rest and medical observation are therefore essential.
Anyone who has shown symptoms of asthma due to this substance should avoid all further contact.
Do NOT spray water on a leaking cylinder (to prevent corrosion of the cylinder).
Turn leaking cylinder with the leak up to prevent escape of gas in liquid state.
