1. SCOPE 1.1 This Standard sets forth minimum requirements for steel, non-pressure tanks that
are used for the aboveground storage of flammable and combustible liquids such as gasoline,
fuel oil, or similar products with a relative density not greater than 1.0. NOTE: These tanks may also be used for the storage of used oil. For tanks intended solely for
the collection of used oil, refer to ULC-S652, Standard for Tank Assemblies for the
Collection of Used Oil. 1.2 This Standard covers tanks, which are fabricated, inspected and tested for
leakage before shipment from the factory. 1.3 This Standard covers the construction of tanks for use in stationary installations.
Tanks fabricated in accordance with this Standard are not intended for the transportation of fuel nor are they intended to be transported while containing fuel.
1.4 The installation of such tanks shall be in accordance with, but not limited to, the
following documents: A National Fire Code of Canada, Part 4; B CSA B139, Installation Code for Oil Burning Equipment; C CCME Environmental Code of Practice for Aboveground and Underground
Storage Tank Systems Containing Petroleum and Allied Petroleum
Products; and D Regulations of the appropriate authority having jurisdiction. 1.5 Section 4 of this Standard covers the construction of single wall tanks. Section 5
covers the construction of tanks with secondary containment. 1.6 This Standard also covers aboveground steel, rectangular, non-pressure
workbench tanks for the combined use as a working surface and storage of lubricating oils
having capacities up to and including 2500 L. 1.7 This Standard also covers aboveground steel, rectangular, non-pressure,
generator-base tanks incorporated into the support structure of diesel engine generators and
used for the storage of the generator’s fuel supply. 1.8 This Standard also covers utility tanks designed to allow for relocation as required
by their intended service. These tanks are for installation at locations such as farms,
construction sites, demolition sites, exploration sites, forestry operations and similar locations. 1.9 This Standard does not cover wind loading or seismic loading of tanks. However,
Guidelines for the Maximum Structural Limitations for Vertical Tanks (A2) are included in
Appendix A.
