Singapore - Guidelines on the Use of Flammable Refrigerants
Business description
On Apr 1, 2026 the Singapore Civil Defence Force (SCDF) published Circular No. CD/05/03/01 - 'Guidelines on the use of Flammable Refrigerants in Singapore'.
The document serves to consolidate and align the requirements which SCDF has implemented for the various refrigeration and air conditioning (RAC) equipment where flammable refrigerants are allowed for use. It is also presupposed that all other relevant regulatory and statutory requirements will be complied with.
Unless otherwise informed, all other non-listed RAC equipment shall continue to use non-flammable refrigerants. This circular is in effect and supersedes the relevant circulars stated in Table 1 of the Guideline.
For equipment listed in Annex A [Air-Conditioning Equipment/Systems, Refrigeration Equipment, Clothes Drying Equipment], a Declaration of Conformity shall be filled up by the manufacturer/supplier and submitted to SCDF for in-principle approval prior to the sale of equipment.
