|ACUTE HAZARDS||PREVENTION||FIRE FIGHTING|
|FIRE & EXPLOSION||Not combustible but enhances combustion of other substances. Many reactions may cause fire or explosion. Risk of fire and explosion. See Chemical Dangers.||NO contact with incompatible materials: See Chemical Dangers||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.|
|AVOID ALL CONTACT! IN ALL CASES CONSULT A DOCTOR!|
|Inhalation||Cough. Sore throat. Shortness of breath. Wheezing. Laboured breathing. Symptoms may be delayed. See Notes.||Use breathing protection, closed system or ventilation.||Fresh air, rest. Half-upright position. Refer immediately for medical attention. Artificial respiration may be needed. See Notes.|
|Skin||ON CONTACT WITH LIQUID: FROSTBITE. Redness. Burning sensation. Pain. Skin burns.||Cold-insulating 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||Watering of the eyes. Redness. Pain. Burns.||Wear 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 immediately for medical attention.|
|Ingestion||Do not eat, drink, or smoke during work.|
|SPILLAGE DISPOSAL||CLASSIFICATION & LABELLING|
|Evacuate danger area! Consult an expert! Personal protection: gas-tight chemical protection suit including self-contained breathing apparatus. Ventilation. Shut off cylinder if possible. Isolate the area until the gas has dispersed. NEVER direct water jet on liquid. Remove gas with fine water spray. Do NOT let this chemical enter the environment.||
According to UN GHS Criteria
DANGERMay cause or intensify fire; oxidizer
Contains gas under pressure; may explode if heated
Fatal if inhaled
Causes severe skin burns and eye damage
May cause respiratory irritation
May cause damage to lungs through prolonged or repeated exposure if inhaled
Very toxic to aquatic life
|Fireproof if in building. Provision to contain effluent from fire extinguishing. Separated from food and feedstuffs. See Chemical Dangers. Cool. Dry. Keep in a well-ventilated room. Store in an area without drain or sewer access.|
|Special insulated cylinder.
|PHYSICAL & CHEMICAL INFORMATION|
Physical State; Appearance
|EXPOSURE & HEALTH EFFECTS|
Routes of exposure
Effects of short-term exposure
Effects of long-term or repeated exposure
|OCCUPATIONAL EXPOSURE LIMITS|
TLV: 0.1 ppm as TWA; 0.4 ppm as STEL; A4 (not classifiable as a human carcinogen).
MAK: peak limitation category: I(1); pregnancy risk group: C.
EU-OEL: 1.5 mg/m3, 0.5 ppm as STEL
|The substance is very toxic to aquatic organisms. It is strongly advised not to let the chemical enter into the environment.|
|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.
The odour warning when the exposure limit value is exceeded is insufficient.
Do NOT use in the vicinity of a fire or a hot surface, or during welding.
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.
