Important Safety Information
Preliminary Precautions
You are working in a potentially dangerous environment of flammable fuels, vapors, and high
voltage or pressures. Only trained or authorized individuals knowledgeable in the related
procedures should install, inspect, maintain or service this equipment.
The first and most important information you must know is how to stop all fuel flow to the
pump and island.
Emergency Total Electrical Shut-Off
Locate the switch or circuit breakers that shut-off all power to all fueling equipment,
dispensing devices, and submerged turbine pumps (STPs). These you must operate in the
event of an emergency.
Total Electrical Shut-Off Before Access
Any procedure requiring access to electrical components or the electronics of the dispenser
requires total electrical shut-off of that unit.
NFPA 30A, Section 4-1.2, published by the National Fire Protection Association, requires the
installation of an easily accessible switch or circuit breaker to shut-off the power to all fueling
equipment, dispensing devices and STPs in the event of an emergency. Know the function and
location of this switch or circuit breaker before inspecting, installing, maintaining, or servicing
Gilbarco equipment.
The EMERGENCY STOP, ALL STOP, and PUMP STOP buttons at the cashier’s station
WILL NOT shut off electrical power to the pump/dispenser.
This means that even if you activate these stops, fuel may continue to flow uncontrolled.
You must use the TOTAL ELECTRICAL SHUT-OFF in the case of an emergency and not
only these cashier station “stops.”
