1,2-DICHLORO-1,1,2,2-TETRAFLUOROETHANE(76-14-2) is a colorless, nearly odorless nonflammable gas. 1,2-DICHLORO-1,1,2,2-TETRAFLUOROETHANE(76-14-2) may be mildly toxic and irritating by inhalation. 1,2-DICHLORO-1,1,2,2-TETRAFLUOROETHANE(76-14-2) can asphyxiate by the displacement of air. Exposure of the container to prolonged heat or fire can cause 1,2-DICHLORO-1,1,2,2-TETRAFLUOROETHANE(76-14-2) to rupture violently and rocket. 1,2-DICHLORO-1,1,2,2-TETRAFLUOROETHANE(76-14-2) is used as a solvent and as a fire extinguishing agent.

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)].

Prolonged exposure can cause narcotic effect or rapid suffocation.

This material is used as a refrigerant and also as a propellant gas

Some may burn but none ignite readily. Containers may explode when heated. Ruptured cylinders may rocket.

If this chemical gets into the eyes, remove any contact lenses at once and irrigate immediately for at least 15 minutes, occasionally lifting upper and lower lids. Seek medical attention immediately. If this chemical contacts the skin, remove contaminated clothing and wash immediately with 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 and CPR if heart action has stopped. Transfer promptly to a medical facility. When this chemical has been swallowed, get medical attention. Give large quantities of water and induce vomiting. Do not make an unconscious person vomit. If frostbite has occurred, seek medical attention immediately; do NOT rub the affected areas or flush them with water. In order to prevent further tissue damage, do NOT attempt to remove frozen clothing from frostbitten areas. If frostbite has NOT occurred, immediately and thoroughly wash contaminated skin with soap and water.

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

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.

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).

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.
