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

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.

VENTING & GAUGING | Normal Venting
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.
