OVERVIEW
Inspecting the petroleum markings on tank vehicles and equipment and directing the proper loading and dispensing of petroleum products from assigned vehicles are necessary for the supervision of tank and pump operations.
Lesson Description:
This lesson covers the procedures for inspecting petroleum markings and loading and unloading tank vehicles.
Terminal Learning Objective:
| Action: | Acquire knowledge on the inspection of petroleum markings on tank vehicles and equipment and identify environmental considerations. |
| Condition: | Given subcourse QM5094. |
| Standards: | The soldier must score a minimum of 70 percent on the end of subcourse examination. |
As a petroleum supervisor, you must be able to ensure that vehicles and equipment are properly marked for both safety reasons and to prevent commingling of products.
Tank vehicles include the M49A2C, M131A5C (Figure 1-1), M967, M969, M970, and M978. The driver’s side of the tanker is the roadside, and the passenger side of the tanker is the curbside.
Safety Markings. Vehicles used for the bulk transportation of gasoline, fuel oil, or other flammable liquids will be marked on both sides and on the rear of the body with the word "FLAMMABLE" in 6-inch block letters, and directly below where space permits, or on the same line with the words "NO SMOKING WITHIN 50 FEET" in 3-inch block letters and numerals. On vehicles which are used under tactical conditions, markings will be lusterless white number 37875. Vehicles which are used on public highways in CONUS, whether military or commercial design, must comply with Title 49, Code of Federal Regulations, Section 177.823, which requires the above markings in red lettering on a white background allowing a 1-inch margin all around the lettering. Lettering will be gloss red number 11105 or 11136, and background will be gloss white number 17875. On vehicles customarily used on public highways, the markings may be permanently installed by painting or by use of adhesive-backed decals. Vehicles infrequently used on public highways and camouflaged vehicles will be marked by the use of removable or reversible signs which are securely fastened while in use. Individual vehicles and convoy must comply with the above requirements.
Type of Product Service. Fuel and oil dispensing vehicles and equipment used for servicing aircraft will be marked with the grade of fuel or oil on each side of the tank. Marking will be lusterless white number 37875 in the following sizes:
Tanker Vehicles Colors.
U.S. Army and Registration Numbers.
According to AR 750-58, there is no further requirement to mark vehicles and equipment with the identification legend "U.S. Army." When vehicles and equipment are camouflaged, both the "U.S. Army" and the registration number will be removed from vehicle/equipment exterior.

Bulk Systems. The piping systems are any pipeline or part thereof used to convey liquid petroleum products, including heating fuel and hydrocarbon missile fuels. These may be classified as tank car and tank truck loading and unloading connections; storage tank valves; pump manifold and valves; cross-country pipelines and their points of tie-in with pumping stations; oil tankers’ connections and manifolds; and other similar dispensing outlets. Storage systems include all exposed fixed storage tanks except aircraft and ships.
Bulk petroleum products and hydrocarbon missile fuels are classified by groups. This method assigns a yellow band (or group of yellow bands) to each of eight groups or similar type products in a distinctive and conspicuous manner as a visual aid and shipment to the written identification. The groups and number of bands are:
|
One narrow band |
|
Two narrow bands |
|
Three narrow bands |
|
Four narrow bands |
|
Five narrow bands |
|
Sign (refer to FM 10-67-1 Concepts and Equipment of Petroleum Operations) |
|
Wide band-narrow band-wide |
|
One wide/one narrow band |
The title shall identify the contents by complete nomenclature, type/grade or product, and military symbol (if established).
A NATO symbol number indicates that the product is interchangeable or has an intended use with a particular product produced in one or more of the NATO participating nations. Systems handling products for which a NATO symbol has been established, and are located in an area subject to servicing ground, sea, or air equipment of NATO countries will, in addition to the NATO symbol, include the appropriate U.S. military symbol. Should the product become off-specification in any respect in any excess of the NATO allowable deterioration limits before use, a line of color contrasting with the NATO symbol and the background color will be drawn diagonally across and beyond the rectangle enclosing the NATO symbol. The thickness of this line will be such that it is clearly visible and the NATO symbol is then considered canceled and the product may, if desired, be considered as an emergency substitute to the original product and will be used only under technical advice. The line or system will be promptly remarked when the deteriorated product is replaced. NATO symbols are:
|
F-49 |
|
F-40 |
|
F-44 |
|
F-58 |
|
F-54 |
|
F-34 |
Yellow is assigned as a primary warning for all flammable materials in accordance with the provisions of the basic code, MIL-STD-101. Black and white are used to mark titles across yellow bands. Markings (which include titles, bands, and arrows) will be applied by painting and stenciling or, if desired, by means of decals, elastomeric film, or reflective sheeting. Markings shall be applied at all receiving concessions; at all dispensing outlets; at all tank fill and discharge lines; at locations where line connections are made to manifolds; and at any other locations necessary to assure ready identification of the product in the system.
On 5-gallon cans:
On 55-gallon drums:
On 500-gallon collapsible drums:
Titles will be applied in such a manner as to be clearly visible from operating positions. The black background will have a minimum border three-fourths of an inch wider than lettered area. For piping smaller than three inches in diameter, metal flags or signs securely fastened to the pipe may be used with the appropriate title and product group band(s) lettered thereon. For multiproduct lines, a flag or sign identifying the product currently in transit may be used in lieu of or as a supplement to the yellow band and nomenclature. An arrow painted in yellow may be used to indicate direction of flow of the product in the line. It will appear adjacent to the title and band(s). In instances where a piping system or tankage is buried or inaccessible, and only a valve stem and wheel or gaging hatch are exposed, a metal flag or brass disc will be used as an aid identifying the product in the facility. The flag post may be permanently fixed to the pipeline or tank or in concrete adjacent thereto. The brass identification disc will be placed on top of the valve or gaging hatch. In concrete pits and similar conditions where space will not permit banding and stenciling of the pipe, the vertical band(s) will be painted on the wall adjacent to the pipe. The title of the product will be stenciled horizontally in white across the band(s). Where pit covers are installed, markings may be applied to the top of the covers.
