Description / Abstract:
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.
