Hazards and Protection.
Storage
Store in dry, well-velentad area away from heat.
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.
Protection
Cold-insulating gloves. Safety goggles, face shield or eye protection in combination with breathing protecton.
Respirators
Wear positive pressure self-contained breathing apparatus (SCBA).
Small spills/leaks
Attempt to stop leak if without undue personnel hazard.
Stability
Stable at room temperature in closed containers under normal storage and handling conditions.
Incompatibilities
Incompatible with certain metal powders (aluminium, zinc, beryllium).
Decomposition
When heated to decomposition it emits highly toxic fumes of hydrogen fluoride and hydrogen chloride.

Fire.
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.
Fire potential
Nonflammable.
Hazards
Vapors from liquefied gas are initially heavier than air and spread along ground.
Combustion products
Toxic fumes of Cl and F

Exposure effects
Headache, dizziness, and disorientation are common. Cerebral edema may be found on autopsy.
   Ingestion
Nausea may develop. Ingestion of a small amount of trichlorofluoromethane resulted in necrosis and perforation of the stomach in one patient.
   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.

First aid
 
   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
Provide a quiet calm atmosphere to prevent adrenaline surge if the patient is seen before the onset of cardiac arrhythmias. Minimize physical exertion.
   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
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.
