Under the Montreal Protocol and
Kigali Amendment, the production and
consumption of these ozone-depleting
substances (ODS) is being or has
been phased out. It is recommended
you ensure compliance with this
universally ratified treaty before
attempting to use these gases, in
addition to R113, R-123, and R-141b.
