Measurements of Sound Pressure Levels for Aerial Shell Mortar Firings and Star Shell Bursts
K. L. Kosanke and B. J. Kosanke Abstract: A large number of sound pressure level (SPL) measurements were recorded for the firing and bursting of firework star shells ranging in size from 3 to 6 inch (75 to 150 mm). The results of a series of 400 measurements of SPLs of firework aerial shell mortar firings …

Shellcalc© – 10 years on. A review of progress and application
Tom Smith Abstract: Shellcalc© was originally developed by John Harradine and published by him and the author of this paper in the Journal of Pyrotechnics. Shellcalc© has been significantly developed since its original publication and now provides a wide range of simulations. The program has been used to model potential hazards from firework comets and …

Recycling of Global Consumer Fireworks
Andrew Tang, Andy Y. F. Tang and Paul Z. J. Peng Abstract: Consumer fireworks is one of the two major fireworks sectors, professional display fireworks and consumer fireworks, in the fireworks industry. It is estimated that consumer fireworks occupy about half of the market share in the global fireworks industry. In terms of packaging materials being …

Numerical Simulation and Validation of Pyrotechnic Smoke Emissions
Abdelkarim Habib and Christian Lohrer Abstract: This paper aims at evaluating the practicability of an alternative strategy for the classical assessment of possible hazards aligned with the use of theatrical pyrotechnics especially at indoor venues, where the emission of solid reaction products (aerosols) is an important factor for permission for the use of pyrotechnics at …

Ordering via the EBSCO Subscription Agency
Unfortunately we have terminated our relationship with the subscription agency EBSCO and all future orders via them will need to be processed directly via this website (an automatic process for single issues, single articles etc) or by contacting the publishers direct (for multi-user and institutional subscriptions).
A proposal to quantify trace levels of hexachlorobenzene in fireworks
Tom Smith and Martin Guest Abstract: Hexachlorobenzene, a persistent organic pollutant, may be present in firework compositions from four sources. This paper makes a proposal to determine what “trace” quantities of hexachlorobenzene may be found in firework compositions, particularly those originating in the Far East where HCB usage was common and contamination still exists. Proposals …
