D Sulphur Hexafluoride (SF6) is a colourless, odourless and non--toxic gas.
D However, it is a gas, which does not maintain life.
This gas is heavier than air and the lower parts such as trenches or cable
troughs can contain a strong concentration of this gas, which could lead to
asphyxia.
NOTE: The maximum permissible concentration on a workstation,
assuming that people stay there 8 hours a day, 5 days a week,
is 1000 ppm (i.e. 0.1%) of the volume. This very low level is a
standard value for all non--toxic gases, which are not usually
present in the atmosphere.
Every recipient containing new SF6 gas should be labelled as indicated
below:
S 7/9 – Keep container tightly closed in a well--
ventilated place.
S 20/21 – When using, do not eat, drink or
smoke.
S 45 – In the event of an acc ident, contac t a
doctor immediately (if possible show the doctor
this label).
S61 -- Avoid release to the env ironment. Refer
to spec ial Ins tructions / Safety Data Sheet.
S 63 – If inhaled, move the victim out of the
contaminated area and keep them still.
