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, 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:
Difluoromethane: LC
50
: Inhalation 4 hr. (rat) - > 520,000 ppm
Pentafluoroethane: Cardiac Sensitization threshold (dog) > 100,000 ppm
DELAYED (SUBCHRONIC AND CHRONIC) EFFECTS:
Teratology – negative
Subchronic inhalation (rat) NOEL – 50,000 ppm
REPEATED DOSE TOXICITY:
Lifetime inhalation exposure of male rats was associated with a small increase in salivary gland fibrosarcomas.
OTHER DATA:
Not active in four genetic studies
FURTHER INFORMATION:
Acute effects of rapid evaporation of the liquid may cause frostbite. Vapors are heavier than air and can displace
oxygen causing difficulty breathing or suffocation. May cause cardiac arrhythmia.
POTENTIAL HEALTH HAZARDS
SKIN: Irritation would result from a defatting action on tissue. Liquid contact could cause frostbite.
EYES: Liquid contact can cause severe irritation and frostbite. Mist may irritate.
