Please note: All interim revisions for this edition available at time of your purchase will be included.

These requirements cover shop fabricated, aboveground atmospheric Fire Resistant Tanks intended for storage of stable flammable or combustible liquids that have a specific gravity not greater than 1.0 and that are compatible with the material and construction of the tank.

These tank constructions are intended to limit the heat transferred to the primary tank when the construction is exposed to a 2-hour hydrocarbon pool fire. Tanks appropriately identified by product markings provide protection for the primary tank against projectile impact and vehicle impact.

Fire Resistant Tanks are intended for stationary installation and use in accordance with the Flammable and Combustible Liquids Code, NFPA 30, and the Automotive and Marine Service Station Code, NFPA 30A.

Tanks covered by these requirements are fabricated, inspected, and tested for leakage before shipment from the factory as completely assembled units.

These requirements and tests are not intended to determine a tank?s acceptability for use after fire exposure, vehicle impact, or projectile impact.

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.

A product that contains features, characteristics, components, materials, or systems new or different from those covered by the requirements in this outline, and that involves a risk of fire, electric shock, or injury to persons shall be evaluated using the appropriate additional component and end-product requirements as determined necessary to maintain the acceptable level of safety as originally anticipated by the intent of this outline. A product whose features, characteristics, components, materials, or systems conflict with specific requirements or provisions of this outline cannot be judged to comply with this outline.
