WARNING
If the provisions of EN 12186 and
EN 12279, national regulations or any
specific manufacturer recommendations
are not put into practice before
installation and if purge by inert gas
is not carried out before equipment’s
start-up and shut-down operations,
a potential external and internal
explosive atmosphere can be present in
equipment and gas pressure regulating,
measuring stations or installations.
If a presence of foreign material in the pipelines is
foreseen and purge by inert gas is not carried out,
the following procedure is recommended to avoid any
possible external ignition source inside the equipment
due to mechanical generated sparks:
• Drainage to safe area via drain lines of foreign
materials, if any, by inflow of fuel gas with low
velocity in the pipe-work (5 m/sec.)
