The truthfulness of the information contained in
Treatment procedures for exafluoride this document is guaranteed by the EPD I –
gas ANPA - 7 validation provided by ANPA.

All processes involving the treatment of SF6

follow the procedures set by the “Technical
brochure no.117” of the CIGRE Guide in order to
avoid the leakage of gas in the atmosphere.
ABB organized a world-wide service centers
network which can offer:
- gas recovery service
- supply or leasing of equipment for gas
treatment
- training courses for personnel in charge of
recycling the gas
