Is tetrafluoroethane harmful to humans?

In a study with human volunteers exposed at concentrations up to 8,000 ppm for 1 h, no adverse effects on pulmonary function, clinical chemistry, hematology parameters, or heart rate or rhythm were observed.

What is tetrafluoroethane used for?

Tetrafluoroethane is used primarily as a refrigerant gas, in manufacturing polymeric foams and as a propellant in aerosols, including inhalers.

Is HFC-134a harmful to humans?

No toxicity data are available on humans following exposure to HFC-134a. Animal studies indicate that HFC-134a has a low level of systemic toxicity following acute, subacute, subchronic, and chronic exposures.

Is tetrafluoroethane a refrigerant?

1,1,1,2-Tetrafluoroethane is a non-flammable gas used primarily as a “high-temperature” refrigerant for domestic refrigeration and automobile air conditioners.

What did R134a replace?

For many years, hydrofluorocarbon (HFC)-134a was the alternate refrigerant of choice to replace chlorofluorocarbon (CFC)-12 in many medium- and high-temperature stationary refrigeration, air conditioning, and automotive air conditioning applications.

Can a refrigerant leak make you sick?

While tasteless and odorless, Freon does make a large impact on your air and health. Refrigerant poisoning is a serious condition that can lead to difficulty breathing, headaches, nausea and vomiting, skin and eye irritation, and coughing.

Is tetrafluoroethane a CFC?

Looks like a CFC! In fact it is a hydrofluorocarbon, an HFC.

What happens if you accidentally inhale R134a?

Swelling in your throat or sinuses. Difficulty breathing. Severe pain in your nose, throat, or sinuses. Burning sensation on your eyes, nose, ears, lips, or tongue.

What happens if you breathe in R134a?

The inhalation of high concentrations of R134a vapour may cause temporary central nervous system depression, with narcosis, lethargy and anaesthetic effects. Continued breathing of high concentrations of R134a vapours may produce cardiac irregularities, unconsciousness and death.

Does R134a damage the ozone?

R134a possesses the zero potential destruction of the ozone layer (PDOL), and its potential of global warming (PGW) of carbonic acid is 1 300, which is much more lower than the PGW of R-12, which is 8 500. R134a does not ignite at the whole range of the exploitation temperatures.
