Description of first aid measures
If inhaledFresh air, rest. Half-upright position. Refer for medical attention. See Notes.
ON FROSTBITE: rinse with plenty of water, do NOT remove clothes.
First rinse with plenty of water for several minutes (remove contact lenses if easily possible), then refer for medical attention.
Rinse mouth with water. Do not induce vomiting. Never give anything by mouth to an unconscious person. Call a doctor or Poison Control Center immediately.

Specific Hazards Arising from the Chemical
Not combustible. Gives off irritating or toxic fumes (or gases) in a fire.
Advice for firefighters
In case of fire in the surroundings, use appropriate extinguishing media. In case of fire: keep cylinder cool by spraying with water.
Personal precautions, protective equipment and emergency procedures
NEVER direct water jet on liquid. Remove vapour with fine water spray. Personal protection: gas-tight chemical protection suit including self-contained breathing apparatus.
Environmental precautions
Prevent further spillage or leakage if it is safe to do so. Do not let the chemical enter drains. Discharge into the environment must be avoided.
Methods and materials for containment and cleaning up
Collect and arrange disposal. Keep the chemical in suitable and closed containers for disposal. Remove all sources of ignition. Use spark-proof tools and explosion-proof equipment. Adhered or collected material should be promptly disposed of, in accordance with appropriate laws and regulations.
Precautions for safe handling
Handling in a well ventilated place. Wear suitable protective clothing. Avoid contact with skin and eyes. Avoid formation of dust and aerosols. Use non-sparking tools. Prevent fire caused by electrostatic discharge steam.
Conditions for safe storage, including any incompatibilities
Fireproof if in building. Keep in a well-ventilated room. Cool. Separated from food and feedstuffs.
Control parameters

Exposure controls
Ensure adequate ventilation. Handle in accordance with good industrial hygiene and safety practice. Set up emergency exits and the risk-elimination area.
Individual protection measures
Eye/face protectionWear face shield or eye protection in combination with breathing protection.
Cold-insulating gloves.
Use ventilation, local exhaust or breathing protection.

Possibility of hazardous reactions
The gas is heavier than air and may accumulate in lowered spaces causing a deficiency of oxygen.Decomposes on heating. This produces toxic fumes including hydrogen fluoride and sulfur oxides.

STOT-single exposure
The substance is severely irritating to the respiratory tract. The substance may cause effects on the central nervous system. This may result in convulsions and respiratory failure. Inhalation of this gas may cause lung oedema. See Notes. Exposure could cause death. Rapid evaporation of the liquid may cause frostbite.
STOT-repeated exposure
no data available
Aspiration hazard
A harmful concentration of this gas in the air will be reached very quickly on loss of containment.

Disposal methods
ProductThe material can be disposed of by removal to a licensed chemical destruction plant or by controlled incineration with flue gas scrubbing. Do not contaminate water, foodstuffs, feed or seed by storage or disposal. Do not discharge to sewer systems.
Containers can be triply rinsed (or equivalent) and offered for recycling or reconditioning. Alternatively, the packaging can be punctured to make it unusable for other purposes and then be disposed of in a sanitary landfill. Controlled incineration with flue gas scrubbing is possible for combustible packaging materials.

Other Information
Turn leaking cylinder with the leak up to prevent escape of gas in liquid state.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.High concentrations in the air cause a deficiency of oxygen with the risk of unconsciousness or death.Check oxygen content before entering area.There is no odour warning even when toxic concentrations are present.
