POTENTIAL HEALTH HAZARDS
SKIN: Irritation would result from a defatting action on tissue. Liquid contact could cause frostbite.
EYES: Liquid contact can cause severe irritation and frostbite. Mist may irritate.
INHALATION: R-22 is low in acute toxicity in animals. When oxygen levels in air are reduced to 12-14% by
displacement, symptoms of asphyxiation, loss of coordination, increased pulse rate and deeper respiration
will occur. At high levels, cardiac arrhythmia may occur.
INGESTION: Ingestion is unlikely because of the low boiling point of the material. Should it occur, discomfort in the
gastrointestinal tract from rapid evaporation of the material and consequent evolution of gas would result.
Some effects of inhalation and skin exposure would be expected.
