TANKS | Shop-Fabricated Tanks

Shop-fabricated tanks are small enough to be produced

in a tank shop and delivered to the site.

• Atmospheric Pressure Tanks—0-1 PSI operating pressure.

• Horizontal Tank: The length of the shall not be greater than 6

times its diameter. Tank diameters exceeding 144 inches shall

not exceed 72 feet in length. July 19, 2013 (UL 142).

• Vertical Tank: The shell height shall not be more than 50 feet and

shall not exceed 60,000 gallons. July 19, 2013 (UL 142)

UL 2583Certified Emergency Vents

UL 2583, an Outline of Investigation for Fuel TankAccessories, is a revised testing protocol in whichemergency vents have been given their ownsection and set of requirements. This is an updatefrom the previous listing requirements to includemodern automotive fuel compatibility andestablish a standard testing protocol.

Effective January 1, 2015



UL 2583

• D975 Diesel (Max B5)• D7467 Low Blend Biodiesel (Max D20)• D4814 Low Blend Ethanol (Max E10)• D5798 High Blend Ethanol (E51-E83)• D4814/D5798 Mid Range Ethanol (E11-E50)



VENTING & GAUGING | Normal Venting





• Normal Venting—Venting Under “Normal” (Non-Emergency)

Conditions

o Open vent allows free movement of air in and out of tank.

Rain hood keeps water out.

Vent height determined by authority having jurisdiction.

Screen keeps bugs and debris out of tank.

Vents outward and upward.



o Pressure/Vacuum Vent (Conservation Vent)—Poppeted

control of relief.

Typical setting 2 oz. – 8 oz. Pressure/1 oz. Vacuum.

Conserves product and reduces vapor discharge.

Vents outward and upward.

UL 2583



o Combination PV Vent/Overfill Alarm

Utilizes only one tank opening.

Audible alarm at high level.



• Flame Arrestor—Prevents the transmission of

heat and/or an ignition source into the tank.

Open Vent Arrestor

Pressure Vacuum Vent

Arrestor





Sizing Normal Vents with Emergency Vents

The emergency vent relief setting should be higher than the

normal vent relief setting.
