First Aid Measures

Ingestion

These substances may cause frostbite to the upper airway and gastrointestinal tract after ingestion. Administer oxygen and manage airway as clinically indicated. Emesis, activated charcoal, and gastric lavage are not recommended.

Inhalation

Move victim to fresh air. Apply artificial respiration if victim is not breathing. Administer oxygen if breathing is difficult.

Skin

Remove contaminated clothing and wash exposed area thoroughly with soap and water. A physician should examine the area if irritation or pain persists. If frostbite has occurred, refer to dermal treatment in the main body of this document for rewarming.

Eyes

If symptoms develop, immediately move individual away from exposure and into fresh air. Flush eyes gently with water for at least 15 minutes while holding eyelids apart; seek immediate medical attention.

Handling and Storage

Storage

Keep in a cool, dry, dark location in a tightly sealed container or cylinder. Keep away from incompatible materials, ignition sources and untrained individuals. Secure and label area. Protect containers/cylinders from physical damage.

Handling

All chemicals should be considered hazardous. Avoid direct physical contact. Use appropriate, approved safety equipment. Untrained individuals should not handle this chemical or its container. Handling should occur in a chemical fume hood.

Hazards Identification

Inhalation

Vapors may cause dizziness or asphyxiation without warning.

Skin

Dermal contact may result in defatting, irritation or contact dermatitis. Severe frostbite has been reported as an effect of freon exposure. Injection causes transient pain, erythema and edema.

Eyes

See Skin.

Ingestion

Nausea may develop. Ingestion of a small amount of trichlorofluoromethane resulted in necrosis and perforation of the stomach in one patient.

Hazards

Containers may explode when heated. Ruptured cylinders may rocket.

Exposure Controls/Personal Protection

Personal Protection

Wear appropriate protective gloves, clothing and goggles.

Respirators

Wear positive pressure self-contained breathing apparatus (SCBA).

Exposure Effects

Headache, dizziness, and disorientation are common. Cerebral edema may be found on autopsy. Dichlorodifluoromethane was not teratogenic in rats and rabbits. <br>The reproductive effects of 1,1,1,2-tetrafluoroethane were studied in rats. No adverse effects on reproductive performance was noted or on the development, maturation or reproductive performance of up to two successive generations.

Poison Class

5

Fire Fighting Measures

Autoignition

>1100

Fire Fighting

Extinguish fire using agent suitable for type of surrounding fire. (Material itself does not burn or burns with difficulty.) Cool all affected containers with flooding quantities of water. Apply water from as far a distance as possible. Do not use water on material itself. Use water spray to knock-down vapors.

Fire Potential

May burn but does not ignite readily.

Accidental Release Measures

Small spills/leaks

Attempt to stop leak if without undue personnel hazard. Use water spray to knock-down vapors.

Stability and Reactivity

Incompatibilities

Incompatible with aluminum.

Stability

Thermally and chemically very inert.

Decomposition

When heated to decomposition it emits toxic fumes of hydrogen fluoride.

Combustion Products

Fire may produce irritating, corrosive and/or toxic gases.
