Freons generally have a low order of toxicity. However, exposure to relatively high
concentrations (>100 ppm) may produce adverse effects on health. Possible exposure routes
include inhalation, ingestion, skin and eye contact (NIOSH, 2003B; NIOSH, 2003C).
Freon vapor may cause irritation of the eyes, nose, throat, and mucous membrane at low
concentrations (Meditext, 2003; Hazardtext, 2003B). At high concentrations, Freon vapor may
cause pulmonary edema and neurological problems such as central nervous system depression,
dizziness, headache, drowsiness, tremors, seizures, confusion, in-coordination, loss of
consciousness, and paralysis (Hazardtext, 2003B; Dupont, 1996A; OSHA, 1998; NIOSH, 2003C).
Inhalation of high concentrations may also result in temporary alteration of the heart's electrical
activity by increasing the sensitivity of the heart to the arrhythmogenic action of epinephrine,
causing irregular pulse, palpitations, or inadequate circulation (Dupont, 1996A; Dupont, 1996F;
OSHA, 1998; Reprotext, 2003). Deliberate inhalation ("sniffing") may cause death without
warning (Dupont, 1996A; Dupont, 1996F; OSHA, 1998).
At extremely high concentrations (several thousand ppm), Freon vapor has the potential to
reduce the amount of oxygen available for breathing, especially in confined spaces, which can
lead to suffocation (Dupont, 1996A; Dupont, 1996F; OSHA, 1998; Reprotext, 2003).
Ingestion of liquid Freon 11 may cause nausea, headache, or weakness (Dupont, 1996B);
ingestion of larger volumes may also cause stomach perforation and necrosis (Hazardtext,
2003B; Lewis, 1997A). Direct eye contact with liquid Freon may cause irritation with discomfort,
tearing, or blurring of vision. Skin contact with liquid Freon can cause frostbite.
Repeated skin contact with liquid Freon may also cause drying of the skin resulting in mild skin irritation with discomfort or rash (Dupont, 1996A; Dupont, 1996F; OSHA, 1998).

R134a Freon is an oxymoron, Freon is R12 but the answer is yes, a subtle 'sweetish' odor
R134a
R134a freon...................
Freon is a brand name. It uses R134a refrigerant.
R134a
R134a is the only freon for cars after 1994. Earlier cars can be retrofitted to R134a.
it takes r134a freon
R134a freon......
It will use R134a Freon..........
First off it contains no Freon. The refrigrant used is not Freon R12 but is R134a. Freon is extremely expensive but R134a is around $7 per 12 ounce can.
