Hazard Assessment and Effect of Nano-Sized Oxidizer on Sound Level Analysis of Firecrackers
T. L.Thanulingam, A. Jeya Rajendran, P. Karlmarx, K. Subramanianc and A. Azhagurajan Abstract: Nano-sized sulphur and oxidizers were synthesized by the ball mill method and the size was determined using a particle size analyzer. Pyrotechnic mixtures of compositions using five different oxidizers: potassium nitrate (KNO3), potassium perchlorate (KClO4), barium nitrate (Ba(NO3)2), strontium nitrate (Sr(NO3)2) and bismuth …

Emissions of Reaction Products and Sound from Outdoor and Indoor Firework Displays
Andreas Dutschke, Stefan Seeger, Lutz Kurth, Ulrich Pannea, and Christian Lohrer Abstract: This work presents results of investigations towards the emission of chemical reaction products and sound pressure during an outdoor and an indoor firework display. Potentially harmful and toxic gases, and aerosols, were measured as well as sound pressures. Aerosols were measured with a …

Pyrotechnically Relevant Salts of 1-(2-Chloroethyl)-5-nitriminotetrazole – Synthesis and Coloring Properties
Thomas M. Klapötke, Jörg Stierstorfer and Karina R. Tarantika Abstract: agents. Salts of strontium are responsible for a red green one and copper salts, only combined with a chlorine donor, are able to yield a blue To investigate the possibility of reducing the amount of metal in pyrotechnic formulations producing colored 1-(2-chloroethyl)-5-nitriminotetrazolato- nitrimino tetrazolate and trans-[diammine-bis{1-(2-chloroethyl)-5-nitrimino …

A New And Fast Method Of Evaluating Powder Energy
Andrew Tang, Hilary Chen and Andy Tang Abstract: In the fireworks or pyrotechnics industry, black powder (nitrate–sulphur–charcoal) is a traditional and commonly used base for creating other chemical compositions. Due to the large variety of pyrotechnic effects, the creation of such different compositions that meet so many needs has led to many different formulations. The …

Burn Rates of Clusters of Colored Sparklers
K. L. and B. J. Kosanke ABSTRACT: In recent years it has become generally known that clusters of sparklers burn at substantially greater rates than individual sparklers. However, except for a previous article by the authors, little if any quantitative data has been presented on this subject. As background information, that article contained a brief …

Pyrotechnic Ignition and Propagation: A Review
K. L. and B. J. Kosanke ABSTRACT: The ideal pyrotechnic is completely stable in storage and handling, yet performs its mission completely, with absolute reliability, upon demand. Many accidents in pyrotechnics are the result of unintentional ignitions during handling and storage. There can also be serious safety ramifications of ignition and propagation failures of pyrotechnic …
