STABILITY AND REACTIVITY
CHEMICAL STABILITY
Material is stable. However, avoid open flames and high temperatures.
CONDITIONS TO AVOID
Avoid open flames and high temperatures.
INCOMPATIBILITY WITH OTHER MATERIALS
Incompatible with alkali or alkaline earth metals- powdered Al, Zn, Be, etc.
DECOMPOSITION
Decomposition Products are hazardous. HCFC-134A can be decomposed by high temperatures
(open flames, glowing metal surfaces, etc.) forming hydrochloric and hydrofluoric acids, and
possibly carbonyl halides.
POLYMERIZATION
Polymerization will not occur.
TOXICOLOGICAL INFORMATION
ANIMAL DATA
ETHANE, 1,1,1,2-TETRAFLUORO
INHALATION: 4 hour, ALC, rat: 567,000 ppm.
SKIN: The compound is a skin irritant and a slight eye irritant but is not a skin sensitizer in animals.
EYE: A short duration spray of vapor produced very slight eye irritation.
Effects from single high exposures include central nervous system depression, anesthesia, rapid
breathing, lung congestion and microscopic liver changes. Cardiac sensitization occurred in dogs at
50,000 ppm or greater from the action of exogenous epinephrine.
