|ACUTE HAZARDS||PREVENTION||FIRE FIGHTING|
|FIRE & EXPLOSION||Not combustible but enhances combustion of other substances.||NO contact with combustible substances.||In case of fire in the surroundings, use appropriate extinguishing media. In case of fire: keep cylinder cool by spraying with water.|
|AVOID ALL CONTACT! IN ALL CASES CONSULT A DOCTOR!|
|SYMPTOMS||ACUTE HAZARDS||FIRST AID|
|Inhalation||Cough. Sore throat. Shortness of breath. Dizziness. Headache. Burning sensation. Laboured breathing. Nausea. Symptoms may be delayed. See Notes.||Use breathing protection, closed system or ventilation.||Fresh air, rest. Half-upright position. Administration of oxygen may be needed. Refer immediately for medical attention.|
|Skin||Redness. Burning sensation. Pain. Serious skin burns.||Protective gloves. Protective clothing.||First rinse with plenty of water for at least 15 minutes, then remove contaminated clothes and rinse again. Refer immediately for medical attention.|
|Eyes||Redness. Pain. Severe burns.||Wear safety goggles or eye protection in combination with breathing protection.||Rinse with plenty of water for several minutes (remove contact lenses if easily possible). Refer immediately for medical attention.|
|Ingestion||Burns in mouth and throat.||Do not eat, drink, or smoke during work.||Rinse mouth. Do NOT induce vomiting. Refer immediately for medical attention.|
|SPILLAGE DISPOSAL||CLASSIFICATION & LABELLING|
|Evacuate danger area! Consult an expert! Personal protection: gas-tight chemical protection suit including self-contained breathing apparatus. Ventilation. Do NOT absorb in saw-dust or other combustible absorbents. Remove vapour with fine water spray. Neutralize used water with chalk or soda.||

|The commercial brown liquid under pressure is an equilibrium mixture of nitrogen dioxide and the colourless nitrogen tetroxide (CAS 10544-72-6).
Non irritant concentration may cause lung oedema.
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.
Immediate administration of an appropriate inhalation therapy by a doctor, or by an authorized person, should be considered.
Rinse contaminated clothing with plenty of water because of fire hazard.
Turn leaking cylinder with the leak up to prevent escape of gas in liquid state.
