• Touch a grounded metal object before starting. Always dissipate static charge from
your body before beginning the fuelling process by touching a grounded metal object at
a safe distance away from fuel sources.
• Use a portable container to fill tank. Never fill the engine’s petrol tank directly from the
fuel pump – the engine’s tank is not grounded and the high velocity flow of petrol from
a fuel pump can cause static electric build-up. Use an approved portable container to
transfer to the engine‘s tank.
• Fill container on the ground. Never fill the portable petrol container while it is sitting
inside a vehicle, trailer, trunk, or pick-up truck bed. ALWAYS place container on the
ground to be filled.
• Keep nozzle in contact with container. Keep nozzle in contact with the portable
container at all times while filling. Manually control the flow of petrol. Do NOT rely on
the nozzles lock-open device.
• Use a portable container made of metal or conductive plastic. It will dissipate charge to
ground more readily.
Typical sources of static electric hazards during fuelling
The following objects can accumulate a static electric charge and cause an ignition
spark in typical fuelling situations:
•
Ungrounded tanks/containers.
Any ungrounded fuel tank or container can
accumulate a static electric charge as a result of contact with other objects or friction
during transportation. This static electricity can discharge as a spark to the grounded
petrol dispenser nozzle, as the nozzle is first brought close to the tank/container at the
beginning of the fuelling process.
•
Flowing Petrol.
Most people are not aware that petrol accumulates static
electric charge while flowing through a hose or pipe. This charge then transfers
to and accumulates in the gas tank or container that is being filled. The total amount
of charge accumulation depends on the amount of gas pumped into the container,
the speed withwhich it is pumped, and whether or not the tank/container is grounded.
If sufficient static electric charge accumulates in the fuel tank or container during the
fuelling process, the tank/ container may discharge a spark to the grounded petrol
dispenser nozzle.
•
Persons.
A person dispensing the petrol can carry a static electric charge on their
body, typically resulting from contact with their car seat or electronics. The static
electricity can discharge as a spark between that person’s hand and either the
grounded dispenser nozzle or the fuel tank opening.
