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.
