“…As shown in Figures 2 and 4 (Azhagurajan et al 2011). Because potassium compounds in black powder (commonly in the form perchlorate or chlorate) act as the main oxidizers, the corresponding chemical equations (2KClO 3 = 2KCl + 3O 2 and KClO 4 = KCl + 2O 2 ) led to high concentrations of Cl − during burning.…”

“…In the fireworks industry, for preparing the firecracker the following ingredients used like sulfur, potassium nitrate and aluminium with a different ratio. The noise level of the firecracker is monitored by using the sound level meter as per the standard regulations are given in Petroleum and Explosive Safety Organization (PESO) and the standard measurement procedure was followed [10].…”

The objective of the study is to increase the safety, health aspects in the workplace and to reduce the environment pollution which occurred during the burning of firecrackers by changing the chemical composition. The normal flash powder chemical composition used in firework industries are potassium nitrate (60%), Aluminum (20%), and sulfur (20%). During the burning of pyrotechnic composition, it releases harmful gases and it leads to health effects to the human being and it pollutes the environment. Similarly, during the preparation of the cracker, workers are exposed by safety hazards. In this work, the mixing ratio of aforementioned chemical powders are changed and thermal analysis, sensitivity analysis like friction, impact and performance test like noise level of firecrackers are carried out for both existing chemical composition and modified chemical composition and it is compared.

“…Pyrotechnics is the science of using materials capable of undergoing selfcontained and self-sustained exothermic chemical reactions for the production of heat, light, gas, smoke and/or sound. Its etymology stems from the Greek word's pyro ("fire") and tekhnikos ("made by art") [1]. Pyrotechnics include not only the manufacture of fireworks but items such as safety matches, oxygen candles, explosive bolts and fasteners, components of the automotive airbag and gas pressure blasting in mining, quarrying and demolition.…”

Fireworks are a class of low explosive pyrotechnic devices used for aesthetic and entertainment purposes. In our project, we automate the fuse insertion process of the Chinese cracker (Bhijili). In India, the fuse insertion is done by handmade process. Due to handmade process, it creates serious health problems to the labours and it requires more labour, consumes more time. So, we planned to implement this process in a “PLC based automatic machine”. In which we combined Piercing, Dipping and Fuse Insertion. In reference of cracker manufacturing in China, they already had automatic fuse insertion, but they have a different procedure (chemical filling is done after the fuse insertion) compared to our country’s procedure, fuse is inserted after chemical filling. In our automation, we sequence the process of piercing and fuse insertion in an automatic manner. Advantage of our project are, increases productivity, reduced lead time, elimination of setup time, reduce the cost, fewer accident. For an emergency safety to the human and the surroundings, we use the fireball (mono ammonium phosphate) for the occasional fire accident which reduces the concentration of the blast in a few seconds.
