PEI Class 7 Test study guide
PEI Class 7 Test · Work through your exam, one topic at a time.
The PEI Class 7 credential is one of the Petroleum Equipment Institute's installation and service certifications for people who work on fueling systems and their containment components. It is aimed at technicians, installers, and inspectors whose job involves sumps, spill buckets, and the piping and tank connections that feed them, and at the contractors who supervise that work. The PEI Class 7 Test study guide has 6 sections and about 1,998 words.
01Safety and Environmental Regulations
The Safety and Environmental Regulations domain tests whether you can tie field work to the federal UST rule in 40 CFR Part 280 and to the site-safety rules that govern every task at a fueling facility: fire prevention, vapor control, confined-space entry, excavation, and release reporting. Part 280 is the baseline for notification, installation, release detection, release reporting, closure, and financial responsibility.
351 words, about 2 min02Liquid and Vapor Piping Systems
Piping is the most frequent release point on a UST system, so this domain tests materials, layout, containment, and the testing that proves the line is tight. Common materials: flexible (often double-wall), fiberglass-reinforced plastic, and coated or galvanically protected steel.
355 words, about 2 min03Containment Sumps and Spill Buckets
Sumps and spill buckets are the small containers that catch what drips and drains. The exam tests whether you can tell a liquid-tight container from a wet one, and whether you know the testing clock.
357 words, about 2 min04Tanks and Tank Appurtenances
This domain covers the tank itself and the fittings that make it work: fill, vent, gauge, monitor, pump, overfill prevention, and corrosion protection. Tank construction: fiberglass, coated or clad steel, or steel with cathodic protection (galvanic or impressed current).
311 words, about 2 min05Release Detection and Leak Monitoring
Release detection answers one question every month: is anything escaping? The exam tests methods, thresholds, frequencies, and how you react to an alarm.
306 words, about 2 min06Installation, Testing, and Inspection
This domain tests sequence: what must be done before, during, and after an installation, and what must be inspected and proven before product goes in the tank. Notify the implementing agency before installation, commonly at least 30 days ahead, and follow the manufacturer's written instructions plus PEI RP100 for underground installation.
