SECTION 4: First aid measures
Description of necessary first-aid measures
Fresh air, rest. Artificial respiration may be needed. Refer for medical attention.
ON FROSTBITE: rinse with plenty of water, do NOT remove clothes. Refer for medical attention .
First rinse with plenty of water for several minutes (remove contact lenses if easily possible), then refer for medical attention.
Rinse mouth with water. Do not induce vomiting. Never give anything by mouth to an unconscious person. Call a doctor or Poison Control Center immediately.
Most important symptoms/effects, acute and delayed
Inhalation at greater than 10% concentration in air may cause narcosis. Liquid may cause frostbite. (USCG, 1999)
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

SECTION 10: Stability and reactivity
Reactivity
Decomposes on contact with hot surfaces or flames. This produces toxic and corrosive gases including hydrogen chloride (see ICSC 0163), phosgene (see ICSC 0007), hydrogen fluoride (See ICSC 0283) and carbonyl fluoride (See ICSC 0633). Attacks magnesium and its alloys.
Chemical stability
The product is stable.
Possibility of hazardous reactions
Not flammable.The gas is heavier than air and may accumulate in lowered spaces causing a deficiency of oxygen.CHLORODIFLUOROMETHANE is incompatible with the following: Alkalis, alkaline earth metals (e.g., powdered aluminum, sodium, potassium, zinc) (NIOSH, 2016).
Conditions to avoid
no data available
Incompatible materials
In a dichlorodifluoromethane system, frictional wear exposed fresh metal surfaces on an aluminum compressor impellor, causing an exothermic reaction which melted much of the impellor. Later tests showed similar results ... with ... chlorodifluoromethane .
Hazardous decomposition products

Persistence and degradability
AEROBIC: Chlorodifluoromethane, present at 1.69 mg/L, reached 0% of its theoretical BOD in 4 weeks using an activated sludge inoculum at 2 mg/L in the Japanese MITI test(1). The maximum oxidation rate measured for chlorodifluoromethane in aerobic soil microcosms incubated with methane and air to simulate the gas composition in landfill soil covers was 0.343 mg/g soil-hour(2).
Bioaccumulative potential
An estimated BCF of 2.4 was calculated in fish for chlorodifluoromethane(SRC), using a log Kow of 1.08(1) and a regression-derived equation(2). According to a classification scheme(3), this BCF suggests the potential for bioconcentration in aquatic organisms is low(SRC).
Mobility in soil
The Koc of chlorodifluoromethane is estimated as 8.6(SRC), using a log Kow of 1.08(1) and a regression-derived equation(2). According to a classification scheme(3), this estimated Koc value suggests that chlorodifluoromethane is expected to have very high mobility in soil. However, since chlorodifluoromethane is a gas(4) under ambient conditions, most of the chemical released on soil will volatilize rapidly, effectively reducing the potential for leaching into groundwater(SRC).
Other adverse effects
no data available
SECTION 13: Disposal considerations
Disposal methods
The material can be disposed of by removal to a licensed chemical destruction plant or by controlled incineration with flue gas scrubbing. Do not contaminate water, foodstuffs, feed or seed by storage or disposal. Do not discharge to sewer systems.
Containers can be triply rinsed (or equivalent) and offered for recycling or reconditioning. Alternatively, the packaging can be punctured to make it unusable for other purposes and then be disposed of in a sanitary landfill. Controlled incineration with flue gas scrubbing is possible for combustible packaging materials.

Other Information
High concentrations in the air cause a deficiency of oxygen with the risk of unconsciousness or death.Check oxygen content before entering the area.The odour warning when the exposure limit value is exceeded is insufficient.Do NOT use in the vicinity of a fire or a hot surface, or during welding.Turn leaking cylinder with the leak up to prevent escape of gas in liquid state.
