Answer:

Friction matches made with white phosphorus as well as those made from phosphorus sesquisulfide can be struck on any suitable surface. They have remained particularly popular in the United States, even when safety matches had become common in Europe, and are still widely used today around the world, including in many developing countries,

for such uses as camping, outdoor activities, emergency/survival situations, and stocking homemade survival kits.

HOWEver, strike-anywhere matches are banned on all kinds of aircraft under the "dangerous goods" classification U.N. 1331, Matches, strike-anywhere.

Safety matches are classified as dangerous goods, "U.N. 1944, Matches, safety". They are not universally forbidden on aircraft; however, they must be declared as dangerous goods and individual airlines or countries may impose tighter restrictions.

Storm matches, also known as lifeboat matches or flare matches, are often included in survival kits. They have a strikeable tip similar to a normal match, but the combustible compound – including an oxidiser – continues down the length of the stick, coating half or more of the entire matchstick. The match also has a waterproof coating (which often makes the match more difficult to light), and often storm matches are longer than standard matches. As a result of the combustible coating, storm matches burn strongly even in strong winds, and can even spontaneously re-ignite after being briefly immersed under water. The pyrotechnics compound burns self-sustained.

modern matches are made of small wooden sticks or stiff paper. One end is coated with a material that can be ignited by frictional heat generated by striking the match against a suitable surface.

Wooden matches are packaged in matchboxes, and paper matches are partially cut into rows and stapled into matchbooks. The coated end of a match, known as the match "head", consists of a bead of active ingredients and binder; often colored for easier inspection. There are two main types of matches: safety matches, which can be struck only against a specially prepared surface, and strike-anywhere matches, for which any suitably frictional surface can be used.
