Insulating gas is a colourless and odourless, chemically neutral, inert and
non-inflammable gas which is heavier than air, not toxic and not harmful to
the ozone layer. Detailed information is given in IEC 60376 and IEC 61634.

3.6 Dealing with pressure-retaining components

Pneumatic energy can lead to serious injury.
With damaged individual components, highly pressurised air can escape and cause eye
injuries, for example.
Pressure-retaining components (e.g. adapters, hoses and external containers) may
burst due to overpressure.
