|Publication Date:||14 February 2006|
This standard shall apply to the following:
Facilities that liquefy natural gas
Facilities that store, vaporize, transfer, and handle liquefied natural gas (LNG)
The training of all personnel involved with LNG
The design, location, construction, maintenance, and operation of all LNG facilities
This standard shall not apply to the following:
Frozen ground containers

All LNG vehicular applications, including fueling of LNG vehicles
Equivalency. Nothing in this standard is intended to prevent the use of systems, methods, or devices of equivalent or superior quality, strength, fire resistance, effectiveness, durability, and safety over those prescribed by this standard.
Technical documentation shall be submitted to the authority having jurisdiction to demonstate equivalency.
The system, method, or device shall be approved for the intended purpose by the authority having jurisdiction.
Retroactivity. The provisions of this standard reflect a consensus of what is necessary to provide an acceptable degree of protection from the hazards addressed in this standard at the time the standard was issued.
Unless otherwise specified, the provisions of this standard shall not apply to facilities, equipment, structures, or installations that existed or were approved for construction or installation prior to the effective date of the standard. Where specified, the provisions of this standard shall be retroactive.
In those cases where the authority having jurisdiction determines that the existing situation presents an unacceptable degree of risk, the authority having jurisdiction shall be permitted to apply retroactively any portions of this standard deemed appropriate.
The retroactive requirements of this standard shall be permitted to be modified if their application clearly would be impractical in the judgement of the authority having jurisdiction and only where it is clearly evident that a reasonable degree of safety is provided.
Metric Practices. Metric units in this standard shall be based on IEEE/ASTM SI 10, Standard for Use of the International System of Units (SI): The Modern Metric System.
Where clearance distances are to be determined, the conversion from U.S. customary units to SI units shall be calculated to the nearest 0.5 m.
Alternate usage of U.S. customary units and SI units on a single project shall not be used to lessen clearance distances.
Referenced Standards. Reference shall be made to both U.S. and Canadian standards, because this standard is prepared for use in both the United States and Canada, as well as in other countries.
Where this standard is adopted, the adoption shall include a statement of whether U.S. or Canadian reference standards shall be used.
If no such statement is made, the user shall use either all available U.S. or all available Canadian reference standards.
If other reference standards are to be used, it shall be so stated.
