Identification of hazards
Specific hazards: rapid evaporation of the liquid can cause frost-bite.
Greater hazards: the vapors are heavier than air and can cause suffocation by reducing the oxygen
available for breathing.
First-aid measures
General information: do not administer anything to persons who have fainted
Inhalation: take the person involved into the fresh air. Give oxygen or artificial respiration if necessary.
Do not administer adrenaline or similar substances.
Contact with eyes: Carefully rinse with plenty of water for at least 15 minutes and see a doctor.
Contact with skin: Wash immediately with plenty of water. Immediately take off contaminated
clothing.
Fire-prevention measures
Appropriate fire-fighting equipment: any
Specific hazards: Pressure rise
Specific fire-fighting methods: cool containers/tanks with water jets.
Measures to be taken in case of
accidental leaks
Individual precautions: evacuate personnel to safety areas.
Environmental precautions: none because the fluid evaporates.
Cleaning methods: not necessary because fluid evaporates.
Handling and storing
Handling
-Technical measures/precautions: make sure sufficient air is circulating in the work premises and/or
that air extraction is adequate
-Hints for safe use: Use only in well-ventilated premises. Do not breathe vapors or aerosols.
Storage
-Technical measures/storage methods: carefully close and keep in a cool, dry and well-ventilated
environment.
-Incompatible products: explosives, flammable materials, organic peroxides
-Packaging materials: keep in original containers

Exposure control / individual protection:
Individual protection:
- breathing protection: during salvage and cfc tank operations, independent breathing apparatus must be
used. The vapors are in fact heavier than air and can cause suffocation by reducing the oxygen available
for breathing.
- eye protection: Safety goggles
- hand protection: rubber gloves.
Specific hygienic precautions: do not smoke.

Stability: no decomposition if used according to instructions.
Conditions to be avoided: contact with alkaline metals, earthy alkaline metals, granulated metal salts,
Aluminum, Zinc, Beryllium, etc. in powder.
Hazardous decomposition products: halogen acids, traces of carbonyl halides.
