3. Hazard
identification
Most important hazards Ambient consequences: not easily biodegradable. Chemical and physical hazards:
thermal decomposition into toxic and corrosive products.
Additional information Not dangerous according to 1999/45/CE.
4. First aid
measures
Inhalation Immediately remove to fresh air. If breathing has stopped, give artificial respiration. Get
medical attention if symptoms persists.
Contact with skin Promptly flush with water for at least 15 minutes. If there is evidence of frostbite, bathe
with lukewarm water. Get medical attention if symptoms persists.
Contact with eyes Immediately flush eyes with large amount of water for at least 15 minutes lifting eyelids
occasionally to facilitate irrigation. Get medical attention.
Ingestion Hospitalization
Protections for aiders If there are high concentrations of refrigerant, the breathing apparatus must be worn.
Notes for the doctor Do not administer catecholamines (because of the cardiac effect caused by the product).
5. Fire fighting
measures
Specific hazard At high temperature - Thermal decomposition giving toxic and corrosive products:
hydrogen fluoride, carbon oxides, one of the components of this preparation gives
flammable mixtures with air.
Specific methods Prohibit all sources of sparks and ignition - Don't smoke. Cool containers / tanks with
water spray. Ensure a system for the rapid emptying of containers. In case of fire nearby,
remove exposed containers.
Special protective equipment
for fire-fighters
Wear self-contained breathing apparatus and protective suit.
6. Accidental
release
measures
Personal precautions Avoid contact with skin and eyes and inhalation of vapours. Use personal protective
equipment. In enclosed areas: ventilate or wear a self-contained breathing apparatus
(risk of anoxia). Remove all sources of ignition. Do not smoke.
Environmental precautions Discharge into the environment must be avoided.
7. Handling and
storage
Handling Technical measures
/ Precautions
Storage and handling precautions applicable to products: gases under pressure, provide
appropriate exhaust ventilation at machinery.
Save handling advice Prohibit ignition sources near the point where containers are opened. Do not smoke.
Storage
Technical measures / Storage
conditions
Store at room temperature in the original container. Keep away from open flames,
hot surfaces and sources of ignition. Keep in a cool, well-ventilated place. Protect full
containers from sources of heat to avoid over pressurization.
Packaging materials
Recommended Ordinary steel
To be avoided Alloys containing more that 2% of magnesium. Plastic materials.
