M-80 (explosive)
M-80s are an American class of large powerful firecrackers, sometimes called salutes. M-80s were originally made in the early 20th century by the U.S. military to simulate explosives or artillery fire; later, M-80s were manufactured as fireworks. Traditionally, M-80s were made from a small cardboard tube, often red, approximately 1 1⁄2 inches (3.8 cm) long and 9⁄16 inch (1.4 cm) inside diameter, with a fuse or wick coming out of the side; this type fuse is commonly known as cannon fuse or Visco fuse, after a company responsible for standardizing the product. The tubes often hold approximately 2½–3 grams of pyrotechnic flash powder; many sources state that an M-80 carries 3 grams of powder.
M-80s are not authorized under the law, thus making importation, possession, transportation, storage or manufacturing illegal in Canada. Firecrackers, including the M-80, can be purchased from Native Reserves in Canada, as they have different governing laws.
Due to potential property damages and bodily harm that can be caused by M-80s, Class C fireworks—now known as consumer fireworks (class 1.4G), as opposed to display fireworks (which were Class B, and are now 1.3G)— civilians require a license, issued by federal authorities, for pyrotechnic devices containing a charge in excess of 50 milligrams of pyrotechnic flash powder. In 1966, M-80s and cherry bombs were restricted by the United States Consumer Product Safety Commission (CPSC) and the Child Protection Act of 1966. In 1975, U.S. federal regulations were passed to limit all consumer-grade fireworks available for general sale to the public in the United States to a maximum of 50 milligrams flash powder, down from a previous maximum of 200 milligrams. However Firecrackers mounted onto a rocket stick, or other aerial firework devices, such as rockets, Roman candles, and cakes etc., may still have significantly more, up to 130 mg, or more, depending on device and classification, and can be legally purchased by any American civilian citizen.
