SECTION 4: First aid measures

Description of necessary first-aid measures

If inhaled

Fresh air, rest. Half-upright position. Artificial respiration may be needed. Refer for medical attention. See Notes.

Following skin contact

Rinse and then wash skin with water and soap.

Following eye contact

First rinse with plenty of water for several minutes (remove contact lenses if easily possible), then refer for medical attention.

Following ingestion

Rinse mouth.

Most important symptoms/effects, acute and delayed

Exposure Routes: inhalation, ingestion, skin and/or eye contact Symptoms: Irritation eyes, skin; central nervous system depression; pulmonary edema; drowsiness; dyspnea (breathing difficulty) Target Organs: Eyes, skin, respiratory system, central nervous system (NIOSH, 2016)

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 deg 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

Persistence and degradability

ANAEROBIC: Structurally similar compounds such as Freon 12 and Freon 114 have been shown to biodegrade under anaerobic conditions(1), suggesting that 1,1,1,2-tetrachloro-2,2-difluoroethane may also biodegrade under anaerobic conditions(SRC).

Bioaccumulative potential

An estimated BCF of 82 was calculated in fish for 1,1,1,2-tetrachloro-2,2,-difluoroethane(SRC), using an estimated log Kow of 3.41(1) and a regression-derived equation(2). According to a classification scheme(3), this BCF suggests the potential for bioconcentration in aquatic organisms is moderate(SRC), provided the compound is not metabolized by the organism(SRC).

Mobility in soil

Using a structure estimation method based on molecular connectivity indices(1), the Koc for 1,1,1,2-tetrachloro-2,2,-difluoroethane can be estimated to be 200(SRC). According to a classification scheme(2), this estimated Koc value suggests that 1,1,1,2-tetrachloro-2,2,-difluoroethane is expected to have moderate mobility in soil.
