3 IDENTIFICATION OF HAZARDS
Identification of hazards Liquefied gas.
The vapours are heavier than air and can cause suffocation, reducing the oxygen available for bre-
athing.
Rapid evaporation of the fluid can cause freezing.
Can cause cardiac arrhythmia.
4 FIRST-AID MEASURES
Inhalation Do not administer anything if the person has fainted.
Take the person outdoors. Use oxygen or artificial respiration if necessary.
Do not administer adrenaline or similar substances.
Contact with eyes Rinse thoroughly with plenty of water for at least 15 minutes and see a doctor.
Contact with skin Wash immediately with plenty of water. Immediately remove all contaminated garments.
Swallowing
5 FIRE-PREVENTION MEASURES
Specific hazards Increase in pressure.
Dangerous fumes Halogen acids, traces of carbonyl halides.
Fire-extinguishing means usable All the known fire-extinguishing means can be used.
Specific methods Cool the containers/tanks with water sprays.
Special protection equipment Use self-contained breathing apparatus in confined spaces.
6 MEASURES AGAINST ACCIDENTAL SPILLING OF THE PRODUCT
Personal protection Evacuate personnel to safe areas. Provide for adequate ventilation. Use personal protection
equipment
Protection for the environment It evaporates.
Product removal methods It evaporates.
7 HANDLING AND STORAGE
Handling and storage Ensure an adequate air change and/or extraction in the workplaces. Only use well-ventilated rooms.
Do not breathe vapours or aerosols. Carefully close the containers and keep them in a cool, dry and
well-ventilated place. Keep in the original containers.
Incompatible products Explosives, flammable materials, organic peroxides.
8 CONTROL OF EXPOSURE / PERSONAL PROTECTION
Personal protection Ensure adequate ventilation, especially in closed areas.
Control parameters Difluoromethane (R32): Recommended exposure limits: AEL (8h and 12h TWA) = 1000 ml/m3
Pentafluoroethane (R125): Recommended exposure limits: AEL (8h and 12h TWA) = 1000 ml/m3
Respiratory tract protection For rescue and for maintenance works in tanks, use self-contained breathing apparatus. The vapours
are heavier than air and can cause suffocation, reducing the oxygen available for breathing.
Eye protection Total protection glasses.
Hand protection Rubber gloves.
Hygiene measures Do not smoke.
9 CHEMICAL-PHYSICAL PROPERTIES
Relative density, gas (air=1) Heavier than air.
Solubility in water (mg/l) Not known, but deemed very low.
Appearance Colourless liquefied gas.
Odour Similar to ether.
Fire point Does not ignite.
10 STABILITY AND REACTIVITY
Stability and reactivity No decomposition if used according to the special instructions.
Materials to be avoided Alkali metals, alkali-earth metals, granulated metal salts, Al, Zn, Be, etc. in powder.
Hazardous products of decomposition Halogen acids, traces of carbonyl halides.
11 TOXICOLOGICAL INFORMATION
Local effects Concentrations substantially above the value TLV (1000 ppm) can cause narcotic effects. Inhalation
of highly concentrated products of decomposition can cause respiratory insufficiency (pulmonary
oedema).
Long-term toxicity No carcinogenic, teratogenic or mutagenic effects have been recorded in experiments on animals.
Specific effects Rapid evaporation of the fluid can cause freezing. Can cause cardiac arrhythmia.
12 ECOLOGICAL INFORMATION
Effects linked to ecotoxicity Pentafluoroethane (R125)
Potential global warming with halocarbides; HGWP (R-11 = 1) = 0.84
Potential impoverishment of the ozone; ODP (R-11 = 1) = 0
