Freon is the tradename of an odorless, colourless and non-flammable group of chemicals used in air conditioners and refrigerators. It is a chemical compound, technically known as a Chlorofluorocarbon or hydro-chlorofluorocarbon; it is part of a group of chemicals known as Halo-alkanes. It is non-toxic to human beings, and have been used since the early 20th century.
Freon is fairly controversial, and some forms were phased out by DuPont during the nineties when CFCs were discovered to be having a negative effect on our atmosphere and environment. Although non-toxic, in 2008 it killed 20 and injured 21 Russian submariners on board the submarine K- 152 Nerpa. A Freon based fire system was activated by mistake during trials, filling cabins with a high concerntration of the substance.
Inhaling directly from a Freon leak can be dangerous, it is heavier than air and when inhaled it can settle in the lungs which can cause lots of problems, inlcuding suffocation. Continual exposure to low levels is very unlikely to cause much of a problem, but in large quantities it can displace oxygen in the lungs and can lead to asphyxiation.
In cars, certain compounds of Freon are used in the air conditioning systems. A story surfaced a few years back claiming to be a researcher for the American Motor Vehicle Safety Organisation (AMVSO) stating that freon is lethal and dangerous. It was essentially claimed that every car produced between 1985 - 1998 is dangerous, and could lead to Alzheimer's disease.
The truth is that the AMVSO does not even exist on record, and the hype created a lot of controversial gossip, about what is a simple problem; if your air conditioning brakes, fix it or get it looked at. In addition, there is no scientific evidence at all that suggests a link between Freon and Alzheimer's.
In conclusion, despite the false worries surrounding the substance in our air conditioners, it is not lethal to humans unless our lungs are flooded with it. It is bad for the environment and the ozone layerr and sustained exposure to it is not recommended. Freon is NOT a dangerous gas, a simple service and even your standard M.O.T will spot a problem with your electrical systems or air conditioning and the amounts used in modern day cars in so negligible that it should make no difference anyway, it just means your car will a bit warm on a hot day unless you open your windows.

Thank you. I have been worried because I drive 1hr one way to work(10-12hrs wk ) I know I have a slow leak as I have refilled the freon twice now. I will get it fixed asap
No problem, glad my article could be of help
I was sprayed in the face when the freezer I was cleaning started to leak. is that going to effect me?
if i where you id go see a doctor asap, im no expert but freon can be very dangerous!
Scientists are stiull divided over the geniune dangers of Freon in small doses but in large amounts it can certainly be damaging to your health and being sprayed in the face with it probably isn't too great!
