A secondary color warning alerts you to the secondary hazard of a material. The second hazard differs from the primary hazard. These colors appear as arrows (or triangles) on piping systems and as main body, top, or band colors on compressed gas cylinders.

Two decalcomanias may be applied on the shoulder of each cylinder diametrically opposite at right angles to the titles. They should indicate the name of the gas, precautions for handling, and use. A background color corresponding to the primary color warning of the content should be used.

A shatterproof cylinder must be stenciled with the phrase "Non-Shat" longitudinally at 90 degrees from the title. Letters must be black or white and approximately 1 inch in size.
