2. Safety
When using the instrument, it is recommended to wear the following protective
equipment.
Safety goggles in accordance with EN 166, class 2, mechanical
strength class S
Safety goggles must be worn during the entire period when working on
hoses or gas containers (e.g. gas cylinders, tanks).
The safety goggles protect the eyes from any flying particles, escaping
gas and liquid splashes.
Protective gloves against heat in accordance with EN ISO 13732-1
and against cold in accordance with EN ISO 13732-3
The protective gloves must be worn over the entire period when working
on hoses, gas containers (e.g. gas cylinders, tanks) or components which
heat up to over 60 °C [140 °F].

Danger of suffocation caused by insulating gases and gas mixtures
High concentrations of gases can lead to asphyxiation, since breathable air is displaced
from the lungs with the inhalation of gas.
Since SF₆ gas is heavier than air, it collects, especially, at ground level or lower-lying
rooms below the reference level (e.g. cellars). This is particularly dangerous since SF6
gas is colourless and odourless and thus may be imperceptible to people.
