|ACUTE HAZARDS||PREVENTION||FIRE FIGHTING|
|FIRE & EXPLOSION||Extremely flammable. Gas/air mixtures are explosive. Risk of explosion on contact with water.||NO open flames, NO sparks and NO smoking. NO contact with halogens, oxidizing agents or water. NO contact with hot surfaces. Closed system, ventilation, explosion-proof electrical equipment and lighting. Prevent build-up of electrostatic charges (e.g., by grounding). Use non-sparking handtools.||Shut off supply; if not possible and no risk to surroundings, let the fire burn itself out. In other cases extinguish with dry powder. NO hydrous agents. 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. Sore throat. Nausea. Laboured breathing. Dizziness. Weakness. Headache. Fever. Tremor. 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 for medical attention.|
|Skin||Frostbite. Frostbite.||Cold-insulating gloves.||ON FROSTBITE: rinse with plenty of water, do NOT remove clothes. Refer for medical attention .|
|Eyes||Severe deep burns.||Wear 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 refer for medical attention.|
|Ingestion||Do not eat, drink, or smoke during work.|
|SPILLAGE DISPOSAL||CLASSIFICATION & LABELLING|
|Evacuate danger area! Consult an expert! Personal protection: complete protective clothing including self-contained breathing apparatus. Ventilation. Remove all ignition sources. Turn off gas at source if possible.||
According to UN GHS Criteria
DANGERExtremely flammable gas

Fatal if inhaled
Causes severe skin burns and eye damage
Causes damage to respiratory system if inhaled
|Fireproof. Separated from strong oxidants, food and feedstuffs and water. Cool. Ventilation along the floor and ceiling. Dry.|
|Special insulated cylinder.
Do not transport with food and feedstuffs.
|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|
|Environmental effects from the substance have not been investigated adequately.|
|The presence of contaminants may lower the auto-ignition temperature so that ignition may occur at or below room temperature.
Reacts violently with fire extinguishing agents such as water.
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 is therefore essential.
The odour warning when the exposure limit value is exceeded is insufficient.
Turn leaking cylinder with the leak up to prevent escape of gas in liquid state.
