What is true about R-134a refrigerant?

R-134a refrigerant is considered non-toxic, which is a significant aspect of its use in refrigeration applications. This characteristic makes it a safer option for both the environment and human health when compared to some other refrigerants that may pose greater risks.

The non-toxic nature of R-134a allows it to be employed in various cooling systems without the same level of concern for health hazards that more toxic refrigerants would present. This is particularly important in commercial and residential applications, where exposure to refrigerants can occur.

In addition to being non-toxic, R-134a has a low environmental impact regarding ozone depletion potential, making it a more environmentally friendly choice at the time of its introduction compared to previous refrigerants. Overall, the non-toxic characteristic is one of the key reasons for the widespread adoption of R-134a in the refrigeration industry.
