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 uids 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 uid types typically used in vehicles.
