The information contained herein is in no way intended to address all safety concerns and/or code requirements associated with the installation or use of abovegroundtanks or associated equipment. This information is provided solely as a guide to the end user during the planning process for an Areo Power installation and will require adjustment as necessitated by local codes and authorities. Areo Power Unitized Fueler, Inc. recommends utilizing the services of a Professional Engineer familiar with national, provincial and local codes to define all requirements and obtain necessary permits prior to installation.


Depending on the characteristics of the fluid being stored, it is necessary to locate aboveground at some minimum distance to property lines, buildings, public ways, etc. and between adjacent tanks. Generally accepted setback distances for tanks storing flammable or combustible are outlined in NFPA 30.


All Areo Power tanks are supplied with an emergency venting device to relieve tank pressure in the case of over pressurization. The total emergency venting capacity required for the Areo tank is the sum of the emergency and normal vent capacities. It is therefore very important that the installer use a normal vent pipe size equal to the nominal diameter of the vent fitting indicated on the tank drawing. The normal vent pipe should terminate at least 12' above grade or 4' above the tank surface, whichever is greater. Vent pipes should also be 5' from any building opening and not located so that vapors may be trapped under eaves or other obstructions. Vent caps should be designed to direct vapors up or horizontally away from the tank or any adjacent obstructions.

Concrete Pad Foundation

It is recommended that a concrete pad foundation be used for all Areo-Power aboveground tanks. A typical specification is 8 inch thick concrete reinforced with 6"x 6", #10 x #10 WWM. The concrete should have a compressive strength of 3500 psi at 28 days. Pad dimensions should be at least 12 inches larger than the tank footprint dimensions all around. In flood plain areas, it is recommended that the tank and dike be secured to the concrete pad to prevent float-off.

Tank Barriers

Depending on the location, it may be necessary to protect the tank and associated equipment from vehicular impact. Bollards, "jersey barriers" or highway guardrail is commonly used for this purpose. Bollards are normally specified as 6" schedule 40 pipe 4' above ground, 2' under, filled with concrete and anchor in 2' diameter, 2' deep concrete. Maximum spacing between barriers is usually 5' and the distance from thetank is usually between 3' and 5'.


Areo Power recommends using suction pumps for dispensing whenever possible. An anti-syphon valve should always be used with suction pumps and should always be at the highest point in the suction piping system (usually at the tank fitting). When this type of system is used the dispenser can be located on the tank or on the pump platform. If a pressurized system is being used (submersible pump) appropriate impact, check and normally closed solenoid valve should be used along with underground piping and concrete dispenser island. Areo Power recommends the use of a "breakaway coupling" on hoses for all dispensing applications.


Filling is normally done at the fill containment chamber at the top of the staircase. A drop tube (fill pipe) is recommend and should terminate within 6" of the tank bottom. Some jurisdictions may require a gauge, vent whistle, high level alarm and/or fill limiting device be installed in aboveground tanks. These items are available through Areo-Power and can be shipped loose with the tank.

Leak Monitoring

The design of the Areo Power tank allows for visible monitoring of the containment dike. Some jurisdictions, however require the use of electronic leak monitoring systems. These items are also available through Areo-Power and can be shipped loose with the tank.


Flammable and Combustible liquid tanks require hazardous location electrical work. All electrical equipment for use in this area should be listed for hazardous locations use. Equipment not rated for hazardous locations must be located outside of the hazardous zones described in NFPA 30A, the National Electrical Code and by the authority having jurisdiction. An emergency electrical disconnect marked "EMERGENCY SHUTOFF SWITCH" should also be mounted in a location visible from the dispenser. Electrical grounding may be required in some locations. Areo Power tanks can be supplied with grounding lugs to aid in fulfilling this requirement.
