32 cards. Read the term and the definition here. The deck at the top of this page is optional.
- Fill limit
- The maximum product level a tank may hold, set to leave room for expansion and to allow overfill devices to function before the tank is overfilled.
- Shear valve
- A valve at the dispenser base that closes on impact or fire to isolate the pressurized product line from the dispenser and limit a release.
- Stage II vapor recovery
- A system that captures gasoline vapor displaced from a vehicle tank during refueling and returns it through the dispenser to the storage tank.
- Spill containment bucket
- A container at the fill point sized to hold product that drains from the delivery hose after disconnect, preventing a spill at the surface.
- Breakaway fitting
- A listed device in the dispenser hose assembly that separates at a defined pull force before the hose or fittings fail, and is replaced after actuation.
- Submersible pump relief
- A bypass or relief arrangement on the submersible pump that limits discharge pressure and protects piping when all dispensers are closed.
- Inventory reconciliation
- A comparison of metered dispensed volume and physical inventory change against deliveries; unexplained loss beyond tolerance triggers a leak investigation.
- Secondary containment sump
- A liquid-tight container around piping or dispenser connections that holds leaked product and is tested for tightness before being placed in service.
- Area classification
- The documented designation of locations by Class, Division or Zone, and material group, which determines the electrical equipment permitted in each area.
- Intrinsic safety barrier
- An approved device that limits energy into a hazardous-area circuit so that no spark or thermal effect can ignite the flammable atmosphere under fault conditions.
- Conduit seal
- A listed sealing fitting installed where conduit leaves a classified area, preventing passage of flammable gas or vapor through the conduit system.
- Equipment bonding
- The connection of tanks, piping, dispensers, and the grounding electrode system into one low-impedance path to prevent static and fault potential differences.
- Emergency shutdown
- A function that removes power from dispensers and pumps independently of the point-of-sale controller, activated from clearly marked locations.
- Motor disconnect
- A means to disconnect the motor branch circuit, located within sight of the motor or capable of being locked open for maintenance.
- Automatic tank gauge
- An electronic system that measures product level and temperature, supports inventory control, and can perform leak detection tests.
- Fire extinguisher rating
- A letter and number classification indicating the extinguisher's suitability for a hazard class and its relative extinguishing capacity for that class.
- Oil-water separator
- A treatment unit that removes free oil from runoff before discharge, sized by the design flow rate from the fueling area.
- Overfill prevention device
- A device that restricts or stops delivery before the tank reaches its safe capacity, checked during inspection for activation and drop tube condition.
- Release detection
- Methods such as tightness testing, automatic tank gauging, and interstitial monitoring used to identify a loss of product from a tank or piping system.
- Vapor balance
- A Stage I arrangement in which displaced tank vapor returns to the delivery tanker through a vapor line during product delivery.
- Buoyancy anchor
- A restraint that holds an empty tank down when groundwater rises above the tank bottom, designed for the empty-tank uplift condition.
- Tank bedding
- The prepared material beneath a tank, installed per the manufacturer's instructions and the engineered design to provide uniform support.
- Commissioning
- Pre-service verification including tightness testing, leak detection checks, and functional testing of shutdowns before product is introduced to the system.
- Hold point
- A defined stage in construction, such as before backfill or first delivery, at which work stops until inspection is completed and released.
- As-built drawing
- A record drawing updated during construction to show the installed configuration, including approved deviations from the design documents.
- Tightness test
- A test conducted at the regulated pressure and duration that passes only when no loss beyond the threshold and no unexplained data change occur.
- Line leak detection test
- An annual verification, by simulated leak or manufacturer procedure, that the line leak detector responds at the regulated leak rate.
- Cathodic protection test
- A measurement confirming that impressed-current or sacrificial anode systems keep the tank or piping structure cathodically protected against corrosion.
- Sump tightness test
- A test of secondary containment sumps and interstitial spaces at the required frequency; failure requires repair and retest before service.
- Flash point
- The lowest temperature at which a liquid gives off vapor in sufficient concentration to ignite near its surface, used to classify liquid hazards.
- Authority having jurisdiction
- The organization that adopts and enforces the applicable fire code and referenced standards, determining the edition and requirements in force.
- Class A, B, C operators
- Operator roles defined by UST regulations, each with assigned responsibilities for daily operation, recordkeeping, and emergency response, with documented training.
