Fireworks are products that can form colors, patterns, and produce sound effects when they are discharged. Firecrackers are products that explode when the main body is exploded and can produce pops, flashes, etc., which are mainly based on auditory effects. Fireworks are developed on the basis of gunpowder. At first, it was a pastime dedicated to the nobility of the nobles. In the Ming and Qing dynasties, the pyrotechnics production technology has developed and become a holiday gift. Fireworks are encouraged every Spring Festival, Lantern Festival and other major events. There are many names of fireworks in China, and the variety of colors and colors is quite mixed. However, the chrysanthemum type is the most popular flower type. After the fireworks entered the sky, the colorful and continuous light agents burned first, followed by the parachutes that followed the fall, the fireworks overlapped, and the night sky was beautifully composed, which formed various beautiful patterns and became the people watching in the 15th month of the first month. aims.
As an inseparable part of folklore, fireworks and firecrackers have always had conflicts with residents' lives and urban security. Since the 1990s, fireworks and firecrackers have been banned in most cities due to the high incidence of accidents in the fireworks industry. With the “restriction of the ban” in the fireworks industry, China's fireworks industry has entered a stage of stable development. Although the fireworks industry has developed and maintained in recent years, the safety of the industry still makes it criticized. Since the product composition contains pyrotechnics with strong lethality, the fireworks and firecrackers industry has a large safety risk in the production process, transportation process, storage process and consumption process.
There is a big gap in the fire safety status of domestic large and small fireworks manufacturers. Large-scale formal fireworks and firecracker production enterprises are generally the key targets for the supervision and management of the government's production safety supervision departments and public security departments. The fire safety facilities and conditions are relatively complete; and because of the large scale of enterprises and investment, due to the consideration of long-term development The company attaches great importance to fire safety work and can strictly abide by all relevant current safety regulations and technical standards, effectively reducing safety risks. Small businesses generally have more serious fire safety hazards. Generally speaking, small-scale enterprises have small capital scales and small-scale production. Most of them are privately run township and village enterprises. The production methods are very irregular, and there are insufficient hardware facilities and employment. The number is large, scattered, and regional. The concentration is low, it is difficult to form an industrial cluster effect, and the safety supervision of high-risk industries is also difficult.
In recent years, the pace of integration of China's fireworks and firecrackers industry has accelerated. Especially under the leadership of the government, some regions have upgraded their industrial status by eliminating large-scale enterprises and supporting advantageous enterprises. Some provinces and cities even directly announced their withdrawal from the fireworks industry. The production areas will also integrate existing enterprises, and the concentration of domestic fireworks industry will become higher and higher. At that time, more funds will be invested in technological development, improve the safety of products, and facilitate the safety supervision of the government. The flammable and explosive nature of the firearm determines that it also poses a certain safety risk during storage and transportation. Seeking the safety of pyrotechnics is one of the ways to develop the industry. Technically, the oxygen balance and combustion temperature of the system can be changed by changing the amount of oxidant and combustibles to control the combustion reaction. At present, the industry's more common method is to replace potassium citrate with potassium permanganate and replace sulfur with sulfur to improve the burning point of pyrotechnics and reduce risks. The tradition of setting off fireworks and firecrackers has a history of more than a thousand years. Every major festival or performance is always a feast of fireworks. However, the safety accidents caused by the fireworks and firecrackers still occur from time to time. The reason is mostly because people are not familiar with the discharge regulations and lack the corresponding knowledge of fire safety. When they celebrate the festive season, they are overly relaxed and vigilant. It can be seen that popularizing the knowledge of fireworks and firecrackers has become a top priority.
