10. STABILITY AND REACTIVITY
NORMALLY STABLE? (CONDITIONS TO AVOID):
The product is stable.
Do not mix with oxygen or air above atmospheric pressure. Any source of high temperature, such as lighted cigarettes,
flames, hot spots or welding may yield toxic and/or corrosive decomposition products.
INCOMPATIBILITIES:
(Under specific conditions: e.g. very high temperatures and/or appropriate pressures) – Freshly abraded aluminum surfaces
(may cause strong exothermic reaction). Chemically active metals: potassium, calcium, and powdered aluminum,
magnesium and zinc.
HAZARDOUS DECOMPOSITION PRODUCTS:
Halogens, halogen acids and possibly carbonyl halides.
HAZARDOUS POLYMERIZATION:
Will not occur.
11. TOXICOLOGICAL INFORMATION
IMMEDIATE (ACUTE) EFFECTS:
LC
50
: 4 hr. (rat) - ≥520,000 ppm (difluoromethane)
Cardiac Sensitization threshold (dog) ≥100,000 ppm (pentafluoroethane)
DELAYED (SUBCHRONIC AND CHRONIC) EFFECTS:
Teratology - negative
Subchronic inhalation (rat) NOEL - 50,000 ppm
OTHER DATA:
Not active in four genetic studies
12. ECOLOGICAL INFORMATION
Degradability (BOD): Genetron AZ-20 (R-410A) is a gas at room temperature; therefore, it is unlikely to remain in water.
Octanol Water Partition Coefficient: Log P
ow
= 1.48 (pentafluoroethane), 0.21 (difluoromethane)
