These requirements cover special purpose nonmetallic containers and tanks (vessels) for specific aboveground use applications for combustible or non-combustible liquids as indicated for each special purpose type, which are intends to address the specific designs, features, limitations, use factors and other unique characteristics of each type. The basic types of different special purpose vessels covered by this Outline are:

a) Liquid Chemical Containers and Tanks designed for stationary storage of combustible or non-combustible liquids in non-residential applications, and are intended to be used in accordance with NFPA 30, Chapter 9 (Storage of Liquids in Containers - General Requirements), Section 9.4 (Acceptable Containers and Tanks). Liquid chemical tanks are limited to the specific liquid(s) or family of similar liquids and application(s) to which they are rated under the evaluation;

b) Cooking Oil Tanks designed for storage of cooking oils and fats typically found in restaurant or similar commercial food preparing applications having engineered transfer systems. These tanks are intended for either delivery of fresh oil and/or collection of waste oils by trained persons using service trucks with pressure or vacuum pumps through piping networks. These tanks are limited to Class IIIB oils & fats, and are intended to be installed in cooking oil storage systems used in commercial kitchens, in accordance with NFPA 1, Chapter 66.19.7 or NFPA 30, Chapter 19.7;

c) Lube Oil Tanks designed for storage, dispensing and collection of Class IIIB motor oils (such as lubricating, transmission, cooling, etc.), working oils (such as hydraulic, brake, steering, cutting, etc.), and other petroleum or synthetic oils with similar chemical and physical properties used in equipment applications; and

d) Vehicle Fluid Tanks for storage, dispensing and collection of non-combustible fluids such as antifreeze/coolants (ethylene-glycol & water mixtures), windshield washer (alcohol, water and detergent mixtures), DEF (nom 1/3 urea and 2/3 water diesel exhaust solution), and other optional fluid types typically used in vehicles.

These requirements do not cover nonmetallic cans, containers or tanks for which there are separately published standards, such as:

a) Bulk Shipping Containers intended for commercial transportation applications in accordance with DOT Hazardous Materials Regulations (Title 49 CFR Parts 100-1999), UN Recommendations on Transport of Dangerous Goods (Part 6), or NMFC (Items 256, 258, 294 & 296);

b) Consumer Portable Fuel Cans in accordance with ASTM Standard Specifications for Gasoline (ASTM F852) or Diesel & Kerosene (ASTM F976), and their Spill Resistant Fueling Systems (ASTM F2234);

c) Portable Containers and Tanks in accordance with UL 75;

d) Commercial Safety Cans in accordance with UL 1313; or

e) Oil Burner Tanks in accordance with UL 2258.

1.3 All special purpose vessels are factory manufactured atmospheric types of primary, secondary or diked containment designs, and are permitted to be constructed in any shape, size or capacity as allowed for each vessel type. The containment materials are formed from primarily thermoplastic or thermoset polymers with or without integrated metallic components. 

In addition to basic requirements for the vessel's structural integrity, material compatibility, environmental exposures and fire resistance, optional requirements for accessories covered in this outline that are installed in/on the tank, such as supports, pumps, heaters, gauges, filters, hoses, valves and controls are permitted in the evaluation. 

Any accessories or components not evaluated under 1.4 that are shipped with, attached to, or added to the tanks are not included in the scope of the vessel's evaluation. It is intended that the AHJ approve the use and/or installation of any such accessories or components independent of the evaluated tank.

These requirements do not cover special evaluations for resistance to hurricanes, tornadoes, earthquakes, floods, or other natural disasters; or large scale fire and excessive damage resistance. In addition, assessment of any damage for continued use after such events, are not included in the evaluation. 

Any common fuel, oil and other liquid terms referenced in this Outline are intended to be those which are commercially available, and which meet a recognized industry specification, such as ASTM, SAE or SCE.
