FAQ

Frequently Asked Questions

Its production and major use have been phased out globally under the Montreal Protocol due to its ozone-depleting properties. Very limited, critical uses may exist under strict exemption.

In industry, it was often called Freon 13, R-13, or simply CFC-13.

It is a stable compound that rises to the stratosphere, where ultraviolet radiation breaks it down, releasing chlorine atoms that catalytically destroy ozone molecules.

It is highly unlikely. Any equipment containing it (like very old commercial refrigeration units) is now rare and subject to strict regulations for recovery and destruction.
