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
Excerpt from ERG Guide 126 [Gases - Compressed or Liquefied (Including Refrigerant Gases)]: Vapors may cause dizziness or asphyxiation without warning. Vapors from liquefied gas are initially heavier than air and spread along ground. Contact with gas or liquefied gas may cause burns, severe injury and/or frostbite. Fire may produce irritating, corrosive and/or toxic gases. (ERG, 2016)
Indication of immediate medical attention and special treatment needed, if necessary
Immediate first aid: Ensure that adequate decontamination has been carried out. If patient is not breathing, start artificial respiration, preferably with a demand-valve resuscitator, bag-valve-mask device, or pocket mask, as trained. Perform CPR if necessary. Immediately flush contaminated eyes with gently flowing water. Do not induce vomiting. If vomiting occurs, lean patient forward or place on left side (head-down position, if possible) to maintain an open airway and prevent aspiration. Keep patient quiet and maintain normal body temperature. Obtain medical attention. Halogenated aliphatic hydrocarbons and related compounds

SECTION 10: Stability and reactivity
Reactivity
Decomposes on contact with hot surfaces or flames. Decomposes above 52°C . This produces hydrofluoric acid. Incompatible with certain metal powders (aluminium, zinc, beryllium).
Chemical stability
Stable under recommended storage conditions.
Possibility of hazardous reactions
Tetrafluoromethane may burn, but does not readily ignite.The gas is heavier than air and may accumulate in lowered spaces causing a deficiency of oxygen.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].
Conditions to avoid

Persistence and degradability
AEROBIC: Highly chlorinated/fluorinated compounds are not expected to biodegrade rapidly(1).
Bioaccumulative potential
An estimated BCF of 3 was calculated in fish for tetrafluoromethane(SRC), using a log Kow of 1.18(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
Using a structure estimation method based on molecular connectivity indices(1), the Koc of tetrafluoromethane can be estimated to be 44(SRC). According to a classification scheme(2), this estimated Koc value suggests that tetrafluoromethane is expected to have very high mobility in soil.
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.
