Assessment on the toxicity and application risk of C4F7N: A new SF6 alternative gas

Journal of Hazardous Materials, 2019
C4F7N (fluorinated nitrile) gas mixture has been utilized as the gas insulating medium to replace the most greenhouse gas SF6 (sulphur hexafluoride). Nowadays, there are few reports on the toxicity mechanism of C4F7N and studies on the application risk of C4F7N is insufficient.
