5-gallon cans. All markings on 5-gallon cans should be in three-fourths inch letters. Place the
marking on the can as shown in figure 2-23.
55-gallon drums. All markings on 55-gallon drums should be at least three-fourths of an inch. Mark
the top head of the drum as shown in figure 2-23.
3 500-gallon collapsible drums. All markings on 500-gallon collapsible drums can vary between 1 to 5
inches. Mark both ends of the drum as shown in figure 2-23. Put the filling date on the drum when you're using it for
temporary storage of petroleum fuels.
(c) Method. Mark containers by brushing or spraying yellow stencil paint over a sharply cut stencil. Other
methods of marking may be used in an emergency; however, the markings must be legible and durable. Mark containers
at the time they are filled. If previous markings are clear and correct, the container does not have to be remarked; just
correct the filling date. Before the container is remarked, paint over old markings as specified in MIL-STD-290. Repaint
markings that have been marred.
(2) Marking containers for waste products. Paint over the original markings on these drums with yellow paint
and paint WASTE PRODUCT on the head of the drums. Then, mark each drum to indicate what product is in it. Wear
safety shoes and neoprene gloves when handling empty drums and packaged products and fuels. In addition, the
equipment used within or around the can and drum storage area must be equipped with flame and spark arresters.
