Circular on Safety of Flammable Refrigerants
In view of the recent upward trend of using the low global warming potential but flammable refrigerants in air-conditioning and refrigeration equipment in some parts of the world, EMSD would like to re-circulate the circular to draw your particular attention.
Moreover, you are welcome to visit a Flammable Refrigerant Safety Website which provides information of flammable refrigerants used in air-conditioning and refrigeration equipment in Hong Kong. The web link is attached below for your easy access:-
