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

Remove victim to fresh air; enforce bed rest; administer oxygen for 30 min. of every hour for 6 hours, even if no symptoms appear.

Skin

If frostbite has occured, apply warm water and treat burn.

Eyes

Irrigate exposed eyes with copious amounts of tepid water for at least 15 minutes. If irritation, pain, swelling, lacrimation, or photophobia persist, the patient should be seen in a health care facility. Ophthamologic consultation should be obtained in any symptomatic patients.

Handling and Storage

Storage

Store in a cool, dry location -- away from incompatible materials. Keep container tightly closed.

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

Pulmonary irritation, bronchial constriction, cough, dyspnea, and chest tightness may develop after inhalation. Chronic pulmonary hyperreactivity may occur. Adult respiratory distress syndrome has been reported following acute inhalational exposures. Pulmonary edema is an autopsy finding in fatal cases.

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

EYES - Eye irritation occurs with ambient exposure. Frostbite of the lids may be severe. NOSE - Nasal irritation occurs with ambient exposure. THROAT - Irritation occurs. Frostbite of the lips, tongue, buccal mucosa and hard palate developed in a man after deliberate inhalation.

Ingestion

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

Hazards

Vapors from liquefied gas are initially heavier than air and spreadalong ground. Vapors may travel to source of ignition and flash back.

Exposure Controls/Personal Protection

Personal Protection

Goggles; rubber gloves.

Respirators

Self-contained breathing apparatus.

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

Fire Fighting Measures

Flash Point

-73

Fire Fighting

Do not extinguish fire unless flow can be stopped. Use water in flooding quantities as fog. Cool all affected containers with flooding quantities of water. Apply water from as far a distance as possible.

Upper exp. limit

38.7

Lower exp. limit

8.4

Fire Potential

Very dangerous, via heat, flames (sparks) or oxidizers.

Accidental Release Measures

Small spills/leaks

Keep sparks, flames, and other sources of ignition away. Keep material out of water sources and sewers. Attempt to stop leak if without undue personnel hazard. Use water spray to knock-down vapors.

Stability and Reactivity

Incompatibilities

Can react with some metals to form dangerous products Incompatible with strong oxidizing and reducing agents Incompatible with many amines; nitrides; azo/diazo compounds; alkali metals; strong oxidizers such as chlorine perchlorate, oxygen, bromine; and epoxides.

Stability

Polymerizes easily.

Decomposition

Oxides of carbon, hydrogen chloride.

Combustion Products

Toxic hydrogen chloride and hydrogen fluoride gases are formed.
