Before working on the engine, ensure that the
gas content of the air is below 10% of the lower
explosive limit (LEL). Also check the permitted
gas content with reference to local laws and reg-
ulations.
When working on the engine, use warning plates
indicating that work with flammable fuel is in
progress. Warning signs should be written in the
local language. Comply with local regulations on
the design of warning signs. An example of the
design of a warning sign is shown in the illustra-
tion.
Inform all personnel of the basic risks of natural
gas and pure biogas.
Check the grounding of the engine where open
handling of gas takes place, i.e. handling which
may give rise to an explosive atmosphere.
Never attempt to put out a burning gas flame. Try
to stop the flow of gas instead. Move material
that could be ignited by the flame.
Electrical system
WARNING!
Before working on the electrical system, ensure
that the gas content of the air is below 10% of the
lower explosive limit (LEL). Also check the per-
mitted gas content with reference to local laws
and regulations.
Switch off the engine and switch off the power
by disconnecting the electrical cables to the bat-
tery. External power supplies to extra equipment
in the engine must also be disconnected.
Always use Scania spare parts for the fuel and
electrical systems. Scania spare parts are de-
signed to minimise the risk of fire and explosion.
