<br />Fluorocarbons enter your body when you breathe their
<br />vapors in the air. Small amounts of the liquid can also
<br />be absorbed through your skin, particularly with
<br />lengthy skin contact. The most common effect of over-
<br />exposure to fluorocarbons is irritation of the skin.
<br />Overexposure to fluorocarbons in the air most com-
<br />monly affects your skin, respiratory tract, or nervous
<br />system, as described below.
<br />Skin, Eyes, Nose and Throat: Fluorocarbons, like
<br />other organic solvents, can dissolve your skin's natural
<br />protective ods- Frequent skin contact with liquid
<br />fluorocarbons can cause dryness, redness, flaking,
<br />cracking, and dermatitis (skin rash). If air concentra-
<br />tions are kept below Cal/OSIWs Permissible Expo-
<br />sure Limits (PELs —see -Legal Exposure Limits on
<br />page 3), fluorocarbons probably will not irritate your
<br />eyes, nose, or throat.
<br />Nervous System: Fluorocarbons, like other organic
<br />solvents, can affect your central nervous system (your
<br />brain) the same waydrinkingalcohol does. Moderate
<br />overexposure for brief periods can cause effects which
<br />Effedior n orocarbons on the"Nervous System
<br />last for only a short time. For the
<br />commonly used fluorocarbons, these
<br />effects can occur at c3posure levels of
<br />.,
<br />about 1000-5000 lapin" ( see M
<br />Exposure Limits-). These effects can
<br />increase your chances of having acci-
<br />dents. At very high exposure levels,
<br />fluorocarbons and other solvents can
<br />cause disorientation, and may make
<br />you pass out.
<br />;6/3%) Some studies suggest that repeated,
<br />frequent overexposure to some
<br />organic solvents over months or years
<br />can have long lasting and possibly
<br />permanent effects on the nervous system. The expo-
<br />sure levels at which these effects occur are not known,
<br />and the effects have not been studied in workers ex-
<br />posed only to fluorocarbons.
<br />The symptoms of these longterm effects include
<br />fatigue, poor muscle coordination, difficulty, concen-
<br />trating, loss of short-term memory, and personality
<br />changes such as increased anxiety, nervousness, and
<br />irritability.
<br />Liver: One infrequently used fluorocarbon, FC -21,
<br />causes liver damage in animals repeatedly exposed to
<br />Zoo ppm or more. For this reason, FC -21 has a lower
<br />Permissible Exposure Limit than other fluorocarbons.
<br />Whether this effect occurs in humans has not been
<br />studied. Other fluorocarbons have not caused liver
<br />damage in animals.
<br />Heart During overexposure to fluorocarbons, your
<br />heart becomes more sensitive to adrenalin. Strenuous
<br />exercise or lack of oxygen, combined with severe over-
<br />exposure (well over 5000 ppm), could cause your heart
<br />to fail. Warning symptoms could include dizziness and
<br />palpitations (skipped heartbeats). However, lower -
<br />level exposures, even over a long period of time, have
<br />not been found to have any effect on the heart.
<br />Cancer. In animal studies, FC -11 and some rarely -
<br />used fluorocarbons (FC -134a, FC -143a) did not cans
<br />canto. FC -22, which is used mainly in refrigeration
<br />and air cooditioning, caused a slight increase in cancer
<br />in animals exposed to a very high level (50,000 ppm)
<br />over their lifetime. Two rarely -used fluor
<br />FC -31 and FC -133a, also caused cancer in animals. No
<br />research has been done to find out whether fluorocar-
<br />bons can cause cancer in humans. However, based on
<br />the available information, if there is any risk of
<br />cancer
<br />from exposure to the commonly used fluorocarbons, it
<br />is likely to be very low.
<br />Reproductive System: In rats, inhalation of FG22
