Stripes mean flammable solid (4.1)

Division 4.1 flammable solids use a white placard with seven red vertical stripes, a flame symbol, and a 4. The candy-stripe look is the signature of 4.1.

Do not confuse it with Class 3

Class 3 flammable liquid is a solid red diamond with a flame. Class 4.1 flammable solid is white with red stripes. Both have a flame, so the background pattern (solid red versus red-and-white stripes) is how you tell them apart.

The rest of Class 4

Class 4 also includes Division 4.2 (spontaneously combustible, white top and red bottom) and Division 4.3 (dangerous when wet, blue). Learning the three together prevents mix-ups. Verify in your official manual.
