Comparison of national “safety distances” at professionally fired firework displays and distances derived from ShellCalc©

Tom Smith & Christian Lohrer Abstract: There is a wide variety of approaches across the world in determining appropriate “safety distances” for firework displays. Comparison of the different national approaches and distances for shells derived from ShellCalc© highlights the variety and derivation of the “safety distances” adopted and these distances are related to the various …

Green Pyrotechnic Formulations Based on Metal-Free and Nitrogen-Rich Tetrazolylborate Salts

Thomas M. Klapötke, Magdalena Rusan and Jörg Stierstorfer Abstract: The investigation of green-burning boron-based compounds as colorants in pyrotechnic formulations as an alternative for environmentally and health hazardous barium nitrate is reported here. Metal-free and nitrogen-rich dihydrobis(5-aminotetrazolyl)borate salts and dihydrobis(1,3,4-triazolyl)borate salts have been synthesized and characterized by NMR spectroscopy, elemental analysis, mass spectrometry and vibrational …

Quantification of Visible Aerosols from Pyrotechnics: Metal and Metal Compound Additives

Rene Yo Abe, Yoshiaki Akutsu, Akihiro Shimada and Takehiro Matsunaga Abstract: The effect of metal and metal compounds commonly used in pyrotechnics on visible aerosol development at high relative humidity has been investigated in combustion experiments using a combustion chamber. Ammonium perchlorate/ hydroxyl-terminated polybutadiene as oxidant/fuel system allowed aerosols generated from the additives to be …
