Ergonomic Hazards in Local Fireworks Factories

Stanley Azzopardi Abstract: The objective of this paper is to review the practices, postures and workstations in Maltese fireworks factories which may cause back pain and musculoskeletal disorders to fireworkers. Hazards varying from the toxicity of substances used to produce colours and pyro-effects up to ergonomic adversities that such processes impose upon the workers are …

Characteristics of the Red Colored Flame of Firework Compositions

Dayu Ding, Daichi Tabata and Tadao Yoshida Abstract:: Experiments have been conducted varying the oxygen balance of fi rework compositions and adding a chlorine donor to compositions in order to understand how or why a red fl ame is affected by the oxygen balance and presence of chlorine in the composition. The results show that …

Effects of Variation of Component Content on the Colored Flame of Firework Star Compositions

Kazuomi Itoh, Hideo Watanabe, Dayu Ding and Tadao Yoshida Abstract: The spectra of the colored flames of firework compositions were measured with a spectrometer and processed into chromaticity coordinates. The change in color purity as a function of composition is shown using chromaticity diagrams. Firework star compositions of red, yellow, green and blue were tested. …

Metal–Fluorocarbon Pyrolants: IX. Burn rate and Radiometric Performance of Magnesium/Teflon/Viton (MTV) Modified with Zirconium

Ernst-Christian Koch Abstract: The burn rate, u (mm s−1) of fuel rich magnesium/Teflon/Viton (MTV) is increased by 65% upon addition of zirconium whereas the spectral efficiency Eβ (J g−1 sr−1) is reduced by 15%.   Keywords: Burn rate, zirconium, magnesium, MTV, polytetrafluoroethylene, radiometry, TeflonTM, VitonTM Ref: JPyro, Issue 28, 2009, pp16-18 (J28_16) 

Fireworks on the Sumida River

Damien Liu-Brennan and Tadao Yoshida Abstract: Fireworks (hanabi) were originally displayed on the Sumida River in 1733 as a memorial service for the victims of starvation due to crop failures and plague, and an epidemic of cholera. The fireworks display originated as the “Ryōgoku Kawabiraki Hanabi” (Ryōgoku River-Opening Fireworks) with only 20 fireworks displayed. Although …

Theory of Colored Flame Production

B. E. Douda Abstract: The theories and attributes associated with the production of colored flames are presented. Particular attention is given to flames containing strontium (red), barium (green), sodium (yellow) and copper (green or blue). Thermal excitation of vaporized neutral atoms, molecules and ions is correlated with the emission of atomic, band and ionic spectra. …
