�� PEI/RP1200-17 11. EMERGENCY STOP WARNING: FIRE AND SPILL HAZARD • "Stop" buttons on the point-of-sale con- sole do not shut off all power to the fuel dispensing system. • In an emergency, activate the dedi- cated and stand-alone emergency stop switch/button. 11.1 General. The emergency stop (E -stop) switch also is called the emergency shutoff switch. When activated, the switch disconnects power to: • all dispensing devices on all islands; • all submersible pumps for all fuel grades that serve dispensing devices; • all power, control and signal circuits associated with the dispensing devices and the submersible pumps; • all other non -intrinsically safe electrical equipment in the classified areas surrounding fuel dispensing devices. If more than one E -stop switch is present, test each switch separately for proper operation. NOTE: Intrinsically safe tank system monitor- ing electrical equipment should not be dis- connected by the E -stop. 11.2 Purpose. This test is performed to determine whether every E -stop switch that is installed at a facility is functioning as designed. 11.3 Description of Test. Each E -stop switch is acti- vated and the entire fueling system is checked to verify that power has been disconnected to: • all dispensing devices on all islands; • all submersible pumps for all fuel grades that serve dispensing devices; • all power, control and signal circuits associated with the dispensing devices and the submersible pumps; • all other non -intrinsically safe electrical equipment in the classified areas surrounding fuel dispensing devices. 11.4 Preparation. Ensure that all customer fueling operations have been discontinued. 0 pei.org • FIGURE 111. The E stop should be clearly labeled and located where it is easily accessible. 11.5 Test Equipment. None needed. Observations are made as to whether the equipment has power or does not have power. 11.6 Test Procedure. 1. Ensure that the system is fully powered in normal operating condition. 2. Depress the E -stop switch. 3. Ensure that power has been disconnected from: • all dispensing devices on all islands; • all submersible pumps for all fuel grades that serve dispensing devices; • all power, control and signal circuits associated with the dispensing devices and the submersible pumps; • all other non -intrinsically safe electrical equipment in the class," :�C i—IT I {3' devices.
