4.First-aid measures
4.1 Description of necessary first-aid measures
General advice
Consult a physician. Show this safety data sheet to the doctor in attendance.
If inhaled
Fresh air, rest. Artificial respiration may be needed. Refer for medical attention.
In case of skin contact
ON FROSTBITE: rinse with plenty of water, do NOT remove clothes. Refer for medical attention .
In case of eye contact
First rinse with plenty of water for several minutes (remove contact lenses if easily possible), then refer for medical attention.
If swallowed
Never give anything by mouth to an unconscious person. Rinse mouth with water. Consult a physician.
4.2 Most important symptoms/effects, acute and delayed
Prolonged exposure can cause narcotic effect or rapid suffocation. (USCG, 1999)
4.3 Indication of immediate medical attention and special treatment needed, if necessary
Victims of freon inhalation require management for hypoxic, CNS anesthetic, & cardiac symptoms. Patients must be removed from the exposure environment, & high flow supplemental oxygen should be utilized. The respiratory system should be evaluated for injury, aspiration, or pulmonary edema & treated appropriately. CNS findings should be treated supportively. A calm environment with no physical exertion is imperative to avoid increasing endogenous adrenegic levels. Exogenous adrenergic drugs must not be used to avoid inducing sensitized myocardial dysrhythmias. Atropine is ineffective in treating bradyarrhythmias. For ventricular dysrhythmias, diphenylhydantoin & countershock may be effective. Cryogenic dermal injuries should be treated by water bath rewarming at 40-42°C until vasodilatory flush has returned. Elevation of the limb & standard frostbite management with late surgical debridement should be utilized. Ocular exposure requires irrigation & slit lamp evaluation for injury. /Freons/
5.Fire-fighting measures

10.Stability and reactivity
10.1 Reactivity
no data available
10.2 Chemical stability
Conditions contributing to instability: heat.
10.3 Possibility of hazardous reactions
The gas is heavier than air and may accumulate in lowered spaces causing a deficiency of oxygen.1,2-DICHLORO-1,1,2,2-TETRAFLUOROETHANE is chemically inert in many situations, but can react violently with strong reducing agents such as the very active metals and the active metals. Can react with strong oxidizing agents or weaker oxidizing agents under extremes of temperature. The reaction of aluminum with various halogenated hydrocarbons produces a self-sustaining reaction with sufficient heat to melt aluminum pieces, examples of other halogenated hydrocarbons are fluorotrichloromethane, dichlorodifluoromethane, chlorodifluoromethane, tetrafluoromethane. The vigor of the reaction appears to be dependent on the combined degree of fluorination and the vapor pressure [Chem. Eng. News 39(27):44(1961)].

AEROBIC: 1,2-Dichloro-1,1,2,2-tetrafluoroethane was reported to be not readily biodegradable using an activated sludge inoculum in the Japanese MITI test(1).
12.3 Bioaccumulative potential
Measured BCF values ranging from 16 to 32 and 15 to 28 at 1,2-dichloro-1,1,2,2-tetrafluoroethane exposure levels of 400 and 40 mg/L, respectively, were reported using carp (Cyprinus carpio) which were exposed over an 6-week period(1). According to a classification scheme(2), this BCF suggests the potential for bioconcentration in aquatic organisms is low to moderate(SRC).
