24、commended practice describes a system for marking equipment used to store and handle bulk petroleum, alcohol-blended petroleum and biodiesel products. The marking system described in this recommended practice does not cover aviation fuels. Marking systems for aviation fuels are described in API/IP S
25、tandard 1542, Identification Markings for Dedicated Aviation Fuel Manufacturing and Distribution Facilities, Airport Storage and Mobile Fuelling Equipment. 1.1.2 A uniform and easily understood identification system facilitates petroleum industry operations. Such a system helps to prevent mixing of
26、multiple products, particularly gasoline with distillates, different grades of unleaded gasoline, gasoline contain-ing alcohol or alcohol containing gasoline versus neat (undiluted) gasoline and distillates containing different sulfur contents.1.1.3 The principal purpose of a marking system is to id
27、entify product transfer points for tank-truck loading and unloading at distribution terminals and retail outlets, and to prevent errors in product handling. Personnel who handle products may make the mistake of “cross-dumping” (commingling) products because these personnel rely on memory rather than
28、 on written records.Gasoline blended to a required Reid Vapor Pressure (RVP) should always remain segregated from gasoline containing alcohol or alcohol containing gasoline as there is a potential for the commingling of the alcohol blend with the neat gasoline. This may result in a violation of vola
29、tility limits imposed on gasoline in certain areas of the country.Ultra low sulfur distillates may be contaminated by higher level distillates and should be handled appropriately to prevent con-tamination. Increased risk of contamination could also be associated with truck transport from the termina
30、l and at retail outlets. API Recommended Practice 1007, Loading and Unloading of MC 306/DOT 406 Cargo Tank Motor Vehicles provides guidelines for preventing contamination. 1.1.4 Personnel who handle products should be trained in and familiar with any identification system used to designate prod-ucts
31、.1.2 SUPPORT OF THE SYSTEM1.2.1 The equipment marking color-symbol system described in this recommended practice facilitates easy identification of products by means of colors, symbols and alphanumeric designations. The following additional measures are recommended to support the system:a. Providing
32、 charts to identify permanent locations of products at a facility (e.g. storage tank, loading arm, etc.).b. Using stencils, decals, or metal or plastic tags to identify product names on equipment.1.2.2 The marking system should be the primary means of identification. Names or product code numbers ar
33、e helpful when a program is initiated, but these should be used as secondary means of identification. Many names contain words common to other products, which can result in incorrect identification; for example, unleaded products may be super unleaded, regular unleaded, or either of these with an ex
34、tender such as ethanol. Company names and product code numbers should be used wherever they are needed to supplement the marking system.1.3 REFERENCED PUBLICATIONSThe following standards, codes, and specifications are cited herein:APIRP 1615 Installation of Underground Petroleum Storage SystemsAPI/I

36、ederal Regulations, Section 279)SECTION 2ELEMENTS OF THE SYSTEM2.1 GENERAL (SEE FIGURE 1)2.1.1 The majority of colors used in this equipment marking color-symbol system remain unchanged from those found in the Second Edition (September 1995). The third edition reflects the industrys changing needs a
37、s a result of the introduction of ultra low sulfur distillates. The previous version included additions to address handling and safety requirements for oxygenated and alcohol-based fuels and slop or waste oil. Additionally, monitoring or observation well identification (as established in API Rec-omm
38、ended Practice 1615) is included here to complete the reference. Only easily distinguishable colors are used; this system does not attempt to define color shades.2.1.2 In the equipment marking color-symbol system, a circle outline represents a gasoline product, a hexagon outline repre-sents a distil
39、late-based product and an elongated pentagon represents an alcohol-blended product. 2.1.3 Superimposed crosses, bars and alpha-numeric designations for product names are used to further distinguish products. 2.1.4 Vapor-recovery connections and manholes are marked with orange circles. The gasoline s
40、ymbol, the circle, is used because the principal environmental concern is with gasoline vapors.Note: Used oil is identified by a purple square. White lettering may be used to supplement the marking system.U.S. EPAs Used Oil Manage-ment Standards (40 Code of Federal Regulations, Section 279) provide
41、additional labeling requirements for used oil storage at generator, trans-fer, or processing and refining facilities.2.1.5 Consistent with API Recommended Practice 1615, monitoring or observation wells are identified with a black equilateral triangle on a white background.2.2 GASOLINE2.2.1 All gasol
42、ine is identified with a circular marking. The marking system does not attempt to classify all the gasoline manu-factured by all the companies that operate refineries. At least five grades of unleaded gasoline are marketed under such names as super premium, premium, mid-regular, regular, and sub-reg
43、ular. In addition, octane can vary by geographical location, season of the year, and refinery batch. The marking system provides for three grades of unleaded gasoline. The gasoline with the highest octane is marked red, the one with the lowest octane is marked white, and any intermediate grade is ma
44、rked blue. This arrange-ment may present a problem in cases in which product is exchanged between two companies, where one company markets three grades of leaded gasoline and the other markets only two. In such cases, product names, octane ratings, or brand code numbers should be used to supplement
45、the marking system. The white crosses on red and blue backgrounds and the black cross on the white background were originally added to identify unleaded gasoline.2.2.2 Also critical in the transfer of bulk gasoline is the differentiation of neat gasoline from gasoline containing oxygenates. This is
46、of particular concern where there are volatility limitations or restrictions regarding the use of such extenders or oxygen-ates. Most areas require the notation of such oxygenated gasoline in transfer or shipping documents. It is an option for the opera-tor to use the appropriate gasoline symbol sur
47、rounded by a white circle for high grade and middle grade and a black circle for low grade to indicate gasoline containing extenders or oxygenates. 2.3 DISTILLATES2.3.1 All distillates are identified with a hexagonal marking. For low sulfur distillate identification, diesel is yellow, No. 1 fuel oil
48、 is purple with a yellow horizontal stripe, No. 2 fuel oil is green, and kerosene is brown. Grades of diesel fuel and kerosene and grades of fuel oil beyond Nos. 1 and 2 are not identified. Individual companies may want to use other means of identification to label these products (see 1.2.2).2.3.2 A
49、 blue horizontal stripe is added to the low-sulfur distillate color-code symbols identified in 2.3.1 to identify high-sulfur distillates.1Environmental Protection Agency, U.S. Government Printing Office, Washington, D.C.07USING THE API COLOR-SYMBOL SYSTEM TO MARK EQUIPMENT AND VEHICLES FOR PRODUCT IDENTIFICATION 32.3.3 A black letter “U” is added to the low-sulfur distillate color-code symbols identities in 2.3.1 to identify ultra low sulfur distillates. This applies to ultra low sulfur diesel (ULSD) and ultra low sulfur kerosene. 2.4 BIODIESEL 2.4.1 Biodiesel shall utilize bronze he
