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 …
