Refrijerans yo ta dwe gen sekirite akseptab. Sekirite sitou gen ladan toksisite ak flammability. Estanda nasyonal la "Refrigerant Nimero Metod ak Sekirite Klasifikasyon" GB / T 7778-2017 klasifye toksisite a nan frijerans nan klas A (toksisite kwonik), Klas B (segonde toksisite kwonik), flammabilite a divize an Klas 1 (pa gen okenn flanm dife), Gwoup 2L (feb flanmable), Klas 2 (flammable), ak Gwoup 3 (flammable ak eksplozif). Dapre GB / T 7778-2017, sekirite a nan frijent se sibdivize nan kategori 8, setadi: A1, A2L, A2, A3, B1, B2L, B2, ak B3. Pami yo, A1 se pi an sekirite ak B3 se pi danjere a.
Nivo sekirite a nan frijent la:
