General Description
1,2-DICHLOROTETRAFLUOROETHANE is a colorless, nearly odorless nonflammable gas. 1,2-DICHLOROTETRAFLUOROETHANE may be mildly toxic and irritating by inhalation. 1,2-DICHLOROTETRAFLUOROETHANE can asphyxiate by the displacement of air. Exposure of the container to prolonged heat or fire can cause 1,2-DICHLOROTETRAFLUOROETHANE to rupture violently and rocket. 1,2-DICHLOROTETRAFLUOROETHANE is used as a solvent and as a fire extinguishing agent.
Reactivity Profile
1,2-DICHLOROTETRAFLUOROETHANE 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)].
Health Hazard
Prolonged exposure can cause narcotic effect or rapid suffocation.
Fire Hazard
Some may burn but none ignite readily. Containers may explode when heated. Ruptured cylinders may rocket.
Safety Profile
An asphyxiant. See also DICHLOROTETRAFLUOROETHANE
Potential Exposure
This material is used as a refrigerant and also as a propellant gas
First aid
If this chemical gets into the eyes, remove anycontact lenses at once and irrigate immediately for at least15 min, occasionally lifting upper and lower lids. Seekmedical attention immediately. If this chemical contacts theskin, remove contaminated clothing and wash immediatelywith soap and water. Seek medical attention immediately.If this chemical has been inhaled, remove from exposure,begin rescue breathing (using universal precautions,including resuscitation mask) if breathing has stopped andCPR if heart action has stopped. Transfer promptly to amedical facility. When this chemical has been swallowed,get medical attention. Give large quantities of water and induce vomiting. Do not make an unconscious personvomit. If frostbite has occurred, seek medical attentionimmediately; do NOT rub the affected areas or flushthem with water. In order to prevent further tissue damage,do NOT attempt to remove frozen clothing fromfrostbitten areas. If frostbite has NOT occurred, immediatelyand thoroughly wash contaminated skin with soap andwater.
Carcinogenicity
Dichlorotetrafluoroethane is considered to
have little or no mutagenic or carcinogenic
potential.
The 2003 ACGIH threshold limit
value-time-weighted average (TLV-TWA)
for dichlorotetrafluoroethane is 1000ppm
(6990mg/m3).
storage
Color Code—Green: General storage may be used.Prior to working with CFC 114 you should be trained on itsproper handling and storage. Dichlorotetrafluoro-ethanemust be stored to avoid contact with acids, acid fumes,chemically active metals, such as sodium, potassium, calcium, powdered aluminum, zinc, and magnesium, since violent reactions occur. Store in tightly closed containers ina cool, well-ventilated area away from heat. Proceduresfor the handling, use, and storage of cylinders should bein compliance with OSHA 1910.101 and 1910.169, aswith the recommendations of the Compressed GasAssociation.
Shipping
UN1958. 1,2-Dichloro-1,1,2,2-tetrafluoroethane or Refrigerant gas R-114, Hazard Class: 2.2; Labels: 2.2- Nonflammable compressed gas. Cylinders must be transported in a secure upright position, in a well-ventilated truck. Protect cylinder and labels from physical damage. The owner of the compressed gas cylinder is the only entity allowed by federal law (49CFR) to transport and refill them. It is a violation of transportation regulations to refill compressed gas cylinders without the express written permission of the owner
Incompatibilities
Keep away from welding and hot metals; decomposes, forming hydrogen chloride and hydrogen fluoride. Reacts with acids and acid fumes forming highly toxic chloride gases. Keep away from chemically active metals: sodium, potassium, calcium, powdered aluminum; zinc, and magnesium. Attacks some plastics and coatings.
Waste Disposal
Return refillable compressed gas cylinders to supplier. Incineration after mixing with combustible fuel. Use flue gas scrubber.
