Risk of fire and explosion on contact with aluminium, zinc, magnesium or oxygen.||NO open flames. NO contact with aluminium, zinc, magnesium or pure oxygen.||Shut off supply; if not possible and no risk to surroundings, let the fire burn itself out. In other cases extinguish with appropriate extinguishing agent. In case of fire: keep cylinder cool by spraying with water.|

Symptoms may be delayed. See Notes.||Use ventilation, local exhaust or breathing protection.||Fresh air, rest. Half-upright position. Artificial respiration may be needed. Refer immediately for medical attention.|
|Skin||MAY BE ABSORBED! Tingling sensation. Itching. Burning sensation. Redness. Blisters. Pain. ON CONTACT WITH LIQUID: FROSTBITE. Further see Inhalation.||Cold-insulating gloves. Protective clothing.||Rinse skin with plenty of water or shower. ON FROSTBITE: rinse with plenty of water, do NOT remove clothes. Refer immediately for medical attention.|
|Eyes||Redness. Pain. Blurred vision. Temporary loss of vision.||Wear safety goggles, face shield or eye protection in combination with breathing protection.||Rinse with plenty of water (remove contact lenses if easily possible). Refer immediately for medical attention.|
|SPILLAGE DISPOSAL||CLASSIFICATION & LABELLING|

Routes of exposure
Effects of short-term exposure
Effects of long-term or repeated exposure
|OCCUPATIONAL EXPOSURE LIMITS|
TLV: 1 ppm as TWA; (skin); A4 (not classifiable as a human carcinogen).
MAK: peak limitation category: I(2); carcinogen category: 3; pregnancy risk group: C
|The substance is toxic to aquatic organisms. Avoid release to the environment because of its impact on the ozone layer. This substance does enter the environment under normal use. Great care, however, should be taken to avoid any additional release, for example through inappropriate disposal.|
|Depending on the degree of exposure, periodic medical examination is suggested.
The symptoms of lung oedema 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.
Toxic effects on the nervous system may be delayed for several hours.
Immediate administration of an appropriate inhalation therapy by a doctor, or by an authorized person, should be considered.
Turn leaking cylinder with the leak up to prevent escape of gas in liquid state.
