ULC ANSI/CAN/UL/ULC 2152:2021 STANDARD FOR SAFETY Special Purpose Nonmetallic Containers and Tanks for Specific Combustible or Noncombustible Liquids

1 Scope

1.1 These minimum 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. The requirements address the specific designs, features, limitations, use factors and

other unique characteristics of each type. The types of different special purpose vessels covered by this

Standard are:

a) Liquid Chemical Containers and Tanks designed for stationary storage of combustible or noncombustible

liquids in non-residential applications, intended to be used in accordance with Table

1.1. Liquid chemical tanks are limited to the specific liquid (s) or family of similar liquids and

application(s) to which they are rated;

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 through piping networks

by trained persons using service trucks with pressure or vacuum pumps. These tanks are limited to

Class IIIB oils and fats, and are intended to be installed in cooking oil storage systems used in

commercial kitchens, in accordance with Table 1.1;

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 and water mixtures), windshield washer (alcohol, water and

detergent mixtures), DEF (nominally 1/3 urea and 2/3 water, diesel exhaust solution), and other

optional fluid types typically used in vehicles.

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 and 296);

b) Consumer Portable Fuel Cans in accordance with ASTM F852, Standard Specification for

Portable Gasoline, Kerosene, and Diesel Containers for Consumer Use;

c) Portable Containers and Tanks in accordance with UL 75, Outline of Investigation for Portable

Containers and Tanks for Flammable and/or Combustible Liquids;

d) Commercial Safety Cans in accordance with UL 1313, Standard for Nonmetallic Safety Cans for

Petroleum Products, or ULC/ORD-C30, Safety Containers; or

e) Oil Burner Tanks in accordance with ANSI/CAN/UL/ULC 2258, Standard for Aboveground

Nonmetallic Tanks for Fuel Oil and Other Combustible Liquids.

1.3 All special purpose vessels are factory manufactured atmospheric types of primary, secondary or

diked containment designs. The containment materials are formed from primarily thermoplastic or

thermoset polymers with or without integrated metallic components.

1.4 In addition to requirements for the vessel's structural integrity, material compatibility, environmental

exposures and fire resistance, requirements for optional accessories that may be installed in or on the

tank, such as supports, pumps, heaters, gauges, filters, hoses, valves and controls are also provided in

this Standard.

1.5 These tanks are intended for installation and use in accordance with applicable documents in the

following list:

a) In Canada:

1) National Fire Code of Canada;

2) CCME PN1326, Environmental Code of Practice for Aboveground and Underground

Storage Tank Systems Containing Petroleum and Allied Petroleum Products;

3) Regulations of the authority having jurisdiction; and

b) In the United States:

1) Standard for the Installation of Oil-Burning Equipment, NFPA 31;

2) Flammable and Combustible Liquids Code, NFPA 30; and

3) Code for Motor Fuel Dispensing Facilities and Repair Garages, NFPA 30A, as applicable.

1.6 Any accessories or components not described in 1.4 that are shipped with, attached to, or added to

the tanks are not included in the scope of this Standard. It is intended that the AHJ approve the use and/or

installation of any such accessories or components independent of the conformance of a tank to these

requirements.

1.7 These requirements do not cover 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 scope of this Standard.

1.8 Any common fuel, oil and other liquid terms referenced in this Standard are intended to describe

fluids which are commercially available, and which meet the requirements of a recognized industry

specification, such as documents published by ASTM, SAE or SCE.
