08 Check of the
exposition /
personal protection
Personal protection. Assure adequate ventilation, especially in closed rooms.
Control parameters. Difluorometan (R32): Recommended limits of exposition: AEL (8h and 12h TWA) = 1000
ml/m3
Pentafluoroetan (R125): Recommended limits of exposition: AEL (8h and 12h TWA) = 1000
ml/m3
Protection of respiratory tract. For the rescue and for service work in the tanks, use an autonomous breather. Vapours are
heavier than the air and can cause choking by reducing the oxygen available for breathing.
Protection for the eyes. Total protection glasses.
Protection for the hands. Rubber gloves.
Hygienic measures. Do not smoke.
09 Chemical
-physical
properties.
Relative density, gas (air=1) Heavier than air.
Solubility in water (mg/l). Not known, but probably very low.
Aspect. Colourless liquefied gas.
Smell. Simile to ether.
Point of ignition. Don’t ignite.
10 Stability
and
reactivity.
Stability and reactivity. No decomposition if used following the instructions.
Materials to avoid. Alkaline metals, earth alkaline metals, granulated metal salts, Al, Zn, Be etc. in powder.
Dangerous decomposition products. Halogen acids, traces of carbonyl halogens.
11 Toxicological
information
Local effects. Concentration substantially above the TLV value (1000 ppm) can cause narcotic effects. Inhalation of products
at high concentration decomposition can cause respiratory insufficiency (pulmonary edema).
Long-term toxicity. It has shown no carcinogenic, teratogen or mutagenic effects on animal experiments.
Specific effects. A rapid evaporation of the liquid can cause freezing. It can cause cardiac arrhythmia.
12 Ecological
information
Effects connected to ecotoxicity
Pentafluoroetan (R125) Potential of global heating of halocarbides; HGWP; (R-11 = 1) = 0.84
Potential of ozone impoverishment; ODP; (R-11 = 1) = 0
13 Disposal
considerations
General considerations. Do not drain where the accumulation can be dangerous
Usable as reconditioning.
Depressurized containers should be given back to the supplier.
Contact the supplier if the use of instructions is necessary.
