10. STABILITY AND REACTIVITY
NORMALLY STABLE? (CONDITIONS TO AVOID):
The product is stable under normal conditions. Explosions may result if in the flammable range. Any source of high
temperatures, 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 reactive metals: potassium, calcium, 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
LC50: 4 hr. (rat) - > 520,000 ppm / Cardiac Sensitization NOEL -350,000 ppm
DELAYED (SUBCHRONIC AND CHRONIC) EFFECTS:
Teratogenic NOEL (rat and rabbit)- 50,000 ppm
Subchronic inhalation (rat) NOEL - 50,000 ppm
OTHER DATA
Not active in four genetic tests.
12. ECOLOGICAL INFORMATION
Degradability (BOD)
R-32 is a gas at room temperature; therefore, it is unlikely to remain in water.
Octanol Water Partition Coefficient
Not applicable
