Assessment on the toxicity and appliion risk of …

C 4 F 7 N (fluorinated nitrile) gas mixture has been utilized as the gas insulating medium to replace the most greenhouse gas SF 6 (sulphur hexafluoride). Nowadays, there are few reports on the toxicity mechanism of C 4 F 7 N and studies on the appliion risk of C 4 F 7 N is insufficient. In this paper, we carried out acute toxicity tests for C 4 F 7 N gas systematically.
