UL 2152-2021 pdf download.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 non- combustible 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.

4.5 CLOSED SECONDARY CONTAINMENT (also known as CLOSED TOP DIKE TANK) – Construction that is external to the primary tank that is designed to prevent the entrance of precipitation and debris into the containment and where the interstitial space is capable of being monitored. 4.6 FUEL – Any flammable liquid having a flash point below 37.8°C (100°F) and a vapour pressure not exceeding 275 kPa (absolute) (40 psi) at 37.8°C (100°F), or any combustible liquid having a flash point at or above 37.8°C (100°F) and below 93.3°C (200°F), and as defined in the National Fire Code of Canada and NFPA 30. A flammable or combustible liquid which is commercially available as an energy source for spark ignition or compression ignition engines, generators, turbines, heaters, or similar equipment; and meets appropriate fuel specifications, such as: a) GASOLINE – General description of various Flammable Class I petroleum distillates and alcohol blends compliant with ASTM D4814, Standard Specification for Automotive Spark-Ignition Engine Fuel, or ASTM D5798, Standard Specification for Ethanol Fuel Blends for Flexible-Fuel Automotive Spark-Ignition Engines, in a range of E0 to E83 or CGSB 3.5, Automotive Gasoline, typically used in spark ignition engines. b) DIESEL – General description of various Combustible Class II petroleum distillates and biodiesel blends compliant with ASTM D975, Standard Specification for Diesel Fuel Oils, or ASTM D7467, Standard Specification for Diesel Fuel Oil, Biodiesel Blend (B6 to B20), or CAN/CGSB 3.517, Diesel Fuel, in a range of B0 to B20 typically used in compression ignition engines.
