|Publication Date:||1 March 2019|
|ICS Code (Stationary containers and tanks):||23.020.10|
|ICS Code (Petroleum products and natural gas handling equipment):||75.200|
(REV1) This Standard covers minimum requirements for shop fabricated, aboveground fire tested tank assemblies intended for storage of flammable and combustible liquids that have a specific gravity not greater than 1.0 and that are compatible with the material of the tank.
In addition to this Standard's traditional safety requirements for aboveground steel tanks that primarily evaluate structural integrity and mitigate 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 included in Appendix A.
Tank assemblies constructed to meet this standard are intended to withstand exposure to a 1 h hydrocarbon pool fire.
These tank assemblies are intended for stationary installation and use in accordance with the following:
A National Fire Code of Canada, Part 4;
B CSA B139, Installation Code for Oil Burning Equipment;
C PN1326, Environmental Code of Practice for Aboveground and Underground Storage Tank Systems Containing Petroleum and Allied Petroleum Products;
D The Requirements of the Authority Having Jurisdiction.
Tank assemblies covered by these requirements are fabricated, inspected, and tested for leakage before shipment from the factory as completely assembled units.
These requirements do not address methods of anchoring which may be required to prevent uplift from flooding or movement due to wind or seismic forces.
These requirements do not address either the construction, or attachment means of ladders, stairs, runways, guardrails, platforms, or equipment supports.
(REV1) The Standards for the primary tank to be incorporated into these fire tested tank assemblies are identified in Subsection 4.2, The Primary Tank. As a result of revisions to those Standards 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 included in Appendix A.
(REV1) Except for optional Climate Change Adaptation requirements in Appendix A, these requirements do not cover special evaluations for resistance to, or use after, earthquakes, floods, high wind events, or other natural disasters; or resistance to vehicle impact.
NOTE 1: See the Note at the beginning of Appendix A for further information on the terms "Adaptation" and "Mitigation", as they pertain to Climate Change.
