What should be done with refrigerants like Ammonia and Hydrogen in small appliances?

Refrigerants like Ammonia and Hydrogen present unique challenges when used in small appliances. While the recovery of most refrigerants is mandated to prevent environmental harm, the specific nature of Ammonia and Hydrogen as refrigerants makes them less suitable for recovery in small appliances.

Ammonia, for example, is typically used in larger industrial refrigeration systems rather than small appliances due to its toxic properties and the necessary safety measures surrounding its use. Hydrogen, while not commonly encountered as a refrigerant, also has safety considerations and is not typically handled in the same manner as traditional refrigerants.

In the context of small appliances specifically, recovering these materials would not only be impractical given their properties but could also pose significant safety risks. Therefore, the appropriate handling of these refrigerants involves alternate methods rather than standard recovery procedures, leading to the understanding that they should not be recovered in such settings.
