Describes the procedures for safe and environmental compatible handling of SF[6] during installation, commissioning, normal and abnormal operations, disposal at the end-of-life of high-voltage switchgear and controlgear.

The scope of this technical report is to address the procedures for safe and environmental compatible handling of SF₆ during installation, commissioning, normal and abnormal operations, disposal at the end-of-life of high-voltage switchgear and controlgear. Storage and transportation of SF₆ are also covered.

These procedures should be regarded as minimum requirements to ensure the safety of personnel working with SF₆ and to minimize the SF₆ emission to the environment.

This technical report generally applies also to gas mixtures containing SF₆.

NOTE 1 For the use of this technical report, the term “ high voltage?? (reference IEV 601-01-27) is the rated voltage above 1 000 V. However, the term “ medium voltage?? (reference IEV 601-01-28) is commonly used for distribution systems with voltages above 1 kV and generally applied up to and including 52 kV.

NOTE 2 Throughout this technical report, the term “electric power equipment?? stands for “high-voltage and medium voltage switchgear and/or controlgear??.
