It is unlikely that a fire will start at a Diesel tank. However,
the stored diesel must be protected from a fire or heat
source that originates nearby. For this reason fuel tanks
of up to 3,500 litres should be separated from openings,
other than airbricks, in the building by a minimum of 1.8m
and a non-fire rated boundary by a minimum of 760mm.
Where this cannot be achieved, a 30 minute fire rated
barrier should be constructed between the hazard and
the tank, which extends a minimum of 300mm higher and
300mm past each end of the tank. Note that a minimum
separation distance should be maintained between a flue
exit and fire barrier (see flue regulations).
Steel tanks must be mounted on brick or block piers with
a waterproof membrane between the piers of the tank.
diesel storage tanks should not be sited within 1.8m of
boiler flue outlets.
Do not allow household waste or hot ashes container in
vicinity of oil storage tank or boiler flue outlet.
