Scope:

1.1 This Standard sets forth the minimum requirements for steel contained tank assemblies that are used for aboveground storage of flammable and combustible liquids such as gasoline, fuel oil, or similar products with a relative density not greater than 1.0.

1.2 This Standard does not cover requirements for accessory devices and appurtenances such as overfill protection, spill containment and sumps.

1.3 This Standard does not cover open secondary containments with or without integral primary tanks per ULC/ORD C142.20.

 

1.4 (REV1) The Standard for the primary tank to be incorporated into these tank assemblies is identified in Subsection 4.1, The Primary Tank. As a result of revisions to that Standard published in 2019, in addition to traditional safety requirements for tanks that primarily evaluate functional operation, structural integrity, and mitigate fire & environmental hazards from loss of liquid containment under expected normal conditions; optional construction and/or performance requirements, and associated ratings, intended to address more severe conditions associated with the effects of Climate Change are now specified in an optional Climate Change Adaptation Appendix in each of those Standards

Project need:

Members of S600A, ULC Standards Committee on Stationary Steel Storage Containers for Flammable and Combustible Liquids, have submitted proposals regarding CAN/ULC-S653 to update the document.
