.3 cubicles are defined as a sealed, pressurized system
which contains sulfur hexafluoride (SF
6
).
SF

is included in the Kyoto Protocol list of greenhouse gases.
SF
6
has a GWP (
Global Warming Potential
) of 22 200 units.
(TAR, IPCC 2001)
At the end of the product’s life, the SF
6
contained in it
must be recovered for processing and recycling, to prevent
it being released into the atmosphere. Extracting and
handling of SF
6
must be carried out by qualified personnel,
using a sealed piercing system.
For the usage and handling of the SF
6
, the indications listed
