UL Standard for Safety Fire Resistant Tanks for Flammable and Combustible Liquids
|Publication Date:||14 March 2000|
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 standard, 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 to determine that the level of safety as originally anticipated by the intent of this standard is maintained. A product whose features, characteristics, components, materials, or systems conflict with specific requirements or provisions of this standard shall not be judged to comply with this standard. Where appropriate, revision of requirements shall be proposed and adopted in conformance with the methods employed for development, revision, and implementation of this standard.
