Recommendations to safety guidelines and standards for the use of natural refrigerants

In order to reduce greenhouse gas emissions, cooling technologies based on natural refrigerants with negligible or insignificant effect on the environment and climate have experienced a renaissance in recent years. A variety of highly efficient applications has been developed and has now reached a technical level that makes their use economically viable. Nevertheless, natural refrigerants require careful handling. This guidance document provides a legislative overview for natural refrigerants, technical guidelines, as well as selected practical recommendations. It focusses on safety concerns originating from flammability, toxicity or high working pressures.
