PEI RP500-19 provides a basic reference that consolidates published and unpublished information from equipment manufacturers, installers, and end users concerning the proper inspection and maintenance of motor vehicle fuel-dispensing equipment. The recommended practice applies to fueling equipment intended to dispense gasoline, diesel and related petroleum products into motor vehicles at commercial and retail fueling facilities. Equipment covered includes all above-grade, liquid- and vapor-handling components from the base of the dispenser cabinet to the nozzle spout.PEI produced this recommended practice to minimize the possibility of fuel-dispensing system failure, to reduce fire hazards, promote fueling safety and minimize environmental problems. Udated in 2019 to include the latest information - the book includes chapters covering definitions, dispenser inspection, documentation, safety and fueling incident response. Chapters are also dedicated to daily, monthly, annual and post-incident fueling system inspections.
