API RP 1637:2006 pdf download.Using the API Color-Symbol System to Mark Equipment and Vehicles for Product ldentification at Gasoline Dispensing Facilities and Distribution Terminals.
2.3.3 A black letter “LY’ 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 sLilfur diesel WLSD) and ultra low sulfur kerosene.
2.4.1 Biodiesel shall utilize bronze hexagonal symbol with an outer yellow band. The inner hexagon is marked with black or white lettering designating (he biodiesel blend (e.g.. 82. 85 or B20).
2.5.1 Alcohol-based fuels arc primarily composed of alcohol with some amount of gasoline blended into the produci Where an alcohol based product is ofkred 11w sale in addition to the three primary gasoline grades, the background color shall be bronze. Black or white lettering (with company names or product codes shall be used to further identify the product. For example. ethanol containing IS volume percent gasoline would be labeled “E-85.”
3.1.1 Equipment should be marked with one large symbol or several small oncs Bands shall he used for rounded surfaces, such as on pipelines and loading arms. Symbols should be placed directly on flat areas or put on tags or placards securely attached to the equipment. A sign similar to that shown in Figure I should be placed at strategic locations for easy reference.
3.1.2 This pennanent marking system has limited application to refineries, because products and other materials flowing through piping and tankage change frequently. Companies may. however, elect to apply the equipment marking color-symbol system to points of product transfer such as loading racks.
3.2.1 Fillboxes and fillbox covers shall be clearly identified (see Figure 2). When fillboxes and lillbox covers are identified by means of the marking system, at least one fixed component of the fillbox itself shall be labeled to avoid commingling accidents that might result from mismatching of flilboxes and their covers. The following labeling methods are recommended:
a. Painting or placing a decal on the top of the cover and on the rim of the lillbox.
h. Attaching a tag securely to the flllpipe adapter.
c. Screwing a tag onto the flllbox rim.
d. Fitting a plastic or fiberglass inseil inside the rim of the fillhox.
3.2.2 Product dispensers do not have to be included in this identification program, since individual companies prefer to use their own colors and symbols when relating to the general public. There is. however, no reason not to adapt the marking system to identify dispensers.
3.3.1 Tank truck, tank-car, and marine loading and unloading facilities shall be identified by means of this system (see Figure
3). Markings should be as close as possible to the point of product transfer.
3.3.2 Storage tanks should be identified by means of this marking system. Labels can help prevent product commingling and afford rapid product recognitiomi.
Delivery vehicles are the most important link in the distribution system and are most susceptible to loading and unloading ernws. By identifying faucet valves with marking system tags or placards, operators can readily match the valves with similarly labeled loading and unloading facilities.
