The dangers of fireworks

Fireworks are a class of explosive pyrotechnic devices used for entertainment purposes. The most common use of a firework is as part of a fireworks display. A fireworks event is a display of the effects produced by firework devices. Fireworks competitions are also regularly held at a number of places. Fireworks take many forms to produce the four primary effects: noise, light, smoke, and floating materials (confetti for example). They may be designed to burn with colored flames and sparks including red, orange, yellow, green, blue, purple, and silver. Displays are common throughout the world and are the focal point of many cultural and religious celebrations.
Fireworks were invented in ancient China in the 7th century to scare away evil spirits, as a natural extension of one of the Four Great Inventions of ancient China, gunpowder. Such important events and festivities as Chinese New Year and the Mid-Autumn Moon Festival were and still are times when fireworks are guaranteed sights. China is the largest manufacturer and exporter of fireworks in the world.
Fireworks are generally classified as to where they perform, either as a ground or aerial firework. In the latter case they may provide their own propulsion (skyrocket) or be shot into the air by a mortar (aerial shell).
The most common feature of fireworks is a paper or pasteboard tube or casing filled with the combustible material, often pyrotechnic stars. A number of these tubes or cases are often combined so as to make, when kindled, a great variety of sparkling shapes, often variously colored. The skyrocket is a common form of firework. The aerial shell, however, is the backbone of today's commercial aerial display, and a smaller version for consumer use is known as the festival ball in the United States.
Ground fireworks, although less popular than aerial ones, create a stunning exhibition. These types of fireworks can produce various shapes, ranging from simple rotating circles, stars and 3D globes.

The earliest documentation of fireworks dates back to 7th century China where they were first used to frighten away evil spirits with their loud sound and to pray for happiness and prosperity. Chinese children grow up with folk stories about one-footed monsters who could be scared away by roasting bamboo for the purpose of producing a loud bang.

Eventually the art and science of firework making developed into an independent profession. In ancient China, pyrotechnicians (firework-masters) were respected for their knowledge and skill in mounting dazzling displays of light and sound.
In China, fireworks for ceremonies and celebrations were mostly for royalties and the rich before the 14th century. It was only in the Ming Dynasty that any event for common people — a birth, a wedding, a business opening, or a New Year's Eve celebration — became a fitting occasion for fireworks.

Improper use of fireworks may be dangerous, both to the person operating them (risks of burns and wounds) and to bystanders; in addition, they may start fires after landing on flammable material. For this reason, the use of fireworks is generally legally restricted. Display fireworks are restricted by law for use by professionals; consumer items, available to the public, are smaller versions containing limited amounts of explosive material to reduce potential danger. Fireworks may pose a problem for animals, both domestic and wild, who can be terrified by the noise, leading to them running away or hurting themselves on fences or in other ways in an attempt to escape.

Pyrotechnical competitions involving fireworks are held in many countries. One of the most prestigious fireworks competition is the Montreal Fireworks Festival, an annual competition held in Montreal, Quebec, Canada. Another magnificent competition is Le Festival d’Art Pyrotechnique held in the summer annually at the Bay of Cannes in Côte d'Azur, France. The World Pyro Olympics is an annual competition amongst the top fireworks companies in the world. It is held in Manila, Philippines. The event is one of the largest and most intense international fireworks competitions.
