Abstract
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.
