RE: Installation of a 1500 gallon liquid oxygen tank
The City of Tigard Building Division has reviewed the submitted building plans for the above
referenced address in accordance with the Oregon Structural Specialty Code (OSSC), 1998
edition.
Plans have been submitted and reviewed for the installation of a 1500 gallon liquid oxygen
storage tank.
City Of Tigard is permitting the installation of the concrete pads and anchoring systems for the
storage tank with vaporizer and the down stream working pressure pipe under 150 psi only.
For the tank, vaporizer, and high pressure piping system contact the State of Oregon Boilers and
Pressure Vessels division for any permits necessary.
Location of the tank and fire department access shall be in accordance with Article 50 of the
UFC. Please see attached Letter for fire department requirements.
If you have any questions regarding this review, please contact me at (503) 369 -4171 ext. 2436

Re: Liquid Oxygen Tank at Fought & Co. Steel
Dear Daryl,
The following conditions from NFPA 50 shall apply:
1. If applicable, an excess flow control valve shall be installed in the product line that enters the building
to mitigate the possibility of the entire contents of the tank being liberated into the building.
2. The bulk oxygen storage location shall be permanently placarded to indicate: "OXYGEN — NO
SMOKING — NO OPEN FLAMES."
3. The vaporizer shall be anchored and its connecting piping shall provide for the effects of expansion
and contraction due to temperature changes.
4. The vaporizer and its piping shall be protected on the oxygen and heating medium sections with
safety relief devices.
5. Storage containers, piping, valves, regulating equipment, and other accessories shall be protected
against physical damage and against tampering by the general public. A shutoff valve shall be
located in liquid product withdrawal lines as close to the container as practical.
6. Bulk oxygen storage systems shall be located aboveground out of doors, or shall be installed in a
building of fire - resistive or noncombustible /limited- combustible construction, adequately vented, and
used for that purpose exclusively. The location selected shall be such that containers and associated
equipment shall not be beneath or exposed by the failure of electric power lines, piping containing all
classes of flammable or combustible liquids or piping containing flammable gases.
7. The system shall be located so that it is readily accessible to mobile supply equipment at ground level
and to authorized personnel. Bulk oxygen systems shall not be located on rooftops of buildings or
other structures.
•••• 8. On bulk liquid oxygen storage systems, the tank's liquid delivery connections, pressure relief device
• • • 8wtlsts, and the mobile supply equipment withdrawal connection shall be at least 8 ft from the inlet of
• • un ee rgrou PSewer systems. •
•
• •
• 9. ongraNstored as a liquid, surfacing of noncombustible material shall be provided at ground
level undef NW connections for the storage container and mobile supply equipment. This
•
• • rr22Cof noo8 i ustible surfacing shall be at least 3 ft in diameter from points at ground level where
•• •• leakage of I�q i oxygen might fall during unloading and normal operation of the system. The area •
• • 1Nder the mobilg•supply equipment shall be at least the full width of the vehicle and at least 8 ft in the
•• • • direction of )he vghide axis. For purposes of this standard, asphaltic or bitumastic paving is
• considered tvbe3ombustible. The slope, if any, of such areas shall take into consideration the
• ' • p ossible flgyv of spilled liquid oxygen to adjacent combustible material. If expansion joints are used,
• fille%shall �IISd bb of noncombustible materials.
• ••••
•
10. Where it is necessary to locate a bulk oxygen system on ground lower than all classes of adjacent
flammable or combustible liquid storage, suitable means shall be taken (such as by diking, diversion
curbs, or grading) with respect to the adjacent flammable or combustible liquid storage to prevent
accumulation of liquids under the bulk oxygen system.
11. 50 ft from buildings of wood frame construction.
12. Not less than 1 ft (or other distance to permit system maintenance) from buildings of other than wood
frame construction.
13. At least 10 ft from any opening in walls of adjacent structures. This provision shall apply to all
elements of a bulk oxygen system where the oxygen storage is high pressure gas. Where the storage
is as a liquid, this provision shall apply to only pressure regulators, safety devices, vaporizers,
manifolds, and interconnecting piping.
14. 50 ft from solid materials that bum rapidly, such as excelsior or paper.
15. 25 ft from solid materials that bum slowly, such as coal and heavy timber.
16. 50 ft from places of public assembly.
17. 10 ft from any public sidewalk or parked vehicles.
18. 5 ft from any line of adjoining property that can be built upon.
19. 25 ft from aboveground flammable and combustible liquid storage tanks of up to 1,000 gallon capacity
and 50 ft from aboveground flammable and combustible liquid storage tanks of more than 1,000
gallon capacity.
Please contact me at (503) 612 -7010 with any additional questions.
Sincerely,
Eric T. McMullen
