Class Code: 4740
Per NCCI's Scopes Code Description:
Code 4740 is applied to insureds engaged in the refining of various crude petroleum oils and the drawing off of the petroleum factions which are natural gas, ligroin, gasoline, kerosene, naphtha, fuel oil, lubricating oil and petrochemicals derived from natural or refinery gases or the cracking of petroleum. Crude oils or partially distilled crude oils are received from others via tank cars, or the oils may be piped in from central storage tank farms. Also, tetraethyl lead and catalysts such as sulphuric and hydrofluoric acids and other additives are received from others. At the refinery, some straight-run gasoline may be produced from the crude oil by distillation without the use of cracking or other chemical conversion processes. This preliminary refining operation also may be performed at an oil production location, usually by separate or contract crews. In this operation, known as topping or skimming, the lighter factions containing the gasoline and naphtha are separated from the heavier fuel oil. The lighter products are shipped to a refinery and the residue of the lower faction is sold as fuel oil. Topping operations, regardless of where performed, are contemplated within the scope of this classification. Refining processes are usually controlled from control rooms containing panels with indicating and recording instruments.
In a typical plant, the operations involve distillation, thermal and/or catalytic decomposition, fractionalization, compression, absorption, purification, storing of gaseous materials, alkylation and the storing or loading of the finished products into tank trucks.
Code 4740 also is applied to insureds engaged in the recovery of gasoline from casing head or natural gases. Casing head or natural gases are received from others via tank cars, or the gases may be piped in from gas storage tank farms. A volatile gasoline is obtained by recovering the butane, pentane and hexane hydrocarbons present in small proportion in the casing head or natural gases. It is used in blending to produce a finished gasoline with adjusted volatility.
Code 4740 additionally contemplates risks engaged in the reclaiming, recycling or rerefining of used motor oil.
Massachusetts Refer to Code 8350 for insureds engaged in the reclaiming or recycling of used motor oils exclusively via a cold filtering process. Refining of used motor oil by distillation or other chemical process is properly assigned to Code 4740.
