Important Changes in Diesel Fuel
Formulation
What You Need to Know About Static Electricity
Risk
The removal of sulfur and other compounds in Ultra
Low Sulfur Diesel (ULSD) fuel decreases its
conductivity and increases its ability to store static
charge. Refineries may have treated the fuel with a
static dissipating additive. However, there are many
factors that can reduce the effectiveness of the
additive over time.
Static charges can build up in ULSD fuel
while it is flowing through fuel delivery
systems. Static electricity discharge
when combustible vapors are present
could result in a fire or explosion.
Therefore, it is important to ensure that
the entire system used to refuel your machine (fuel
supply tank, transfer pump, transfer hose, nozzle,
and others) is properly grounded and bonded.
Consult with your fuel or fuel system supplier to
ensure the delivery system is in compliance with
fueling standards for proper grounding and bonding
practices.
What is Basic Bonding and
Grounding? Why is it Important
During Refueling?
Bonding:
A properly bonded fuel delivery system has an
electrically conductive and unbroken connection
between all components of the fuel delivery system.
Fuel supply tank, transfer pump, transfer hose,
nozzle, and others.
A wire connection from the fuel delivery system
to the machine chassis will equalize the static
electric potential between the two machines,
further reducing the chance of a static electric
discharge.
Grounding:
A properly grounded fuel delivery system has an
electrically conductive connection from the fuel
delivery system tank to earth ground to allow static
and electrical charge dissipation.
