What is the most toxic refrigerant?

CFCs and HCFCs are the most harmful because they contain chlorine. These refrigerants are also relatively stable, meaning they don't get destroyed easily by rain or sunlight. This makes it more likely that they will reach the stratosphere, where the ozone layer is.

Is R22 refrigerant toxic?

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.

Which Gases are the Most Toxic?



What happens if you accidentally put 410A in a R22 system?

If you put R410-A into an R-22 system, the parts will rupture due to the increased force. You can convert your current system to one that runs on R-410A, but the cost will be high.

Is R410A worse than R-22?

Because R-410A can absorb and release more heat than R-22, your air conditioning compressor can run cooler, reducing the risk of compressor burnout due to overheating. R-410A also functions at a higher pressure than R-22, so new compressors are built to withstand greater stresses, reducing the chance for cracking.
