Reveiw by John Bergman This publication addresses a much wider range of hearing protection issues than explosive noise per se. Despite its being structured specifically around British standards and regulations, its applicability to noise sources of all kinds should make it useful to safety personnel and industrial hygienists in any manufacturing environment. The guide opens …

Review of: Explosives Engineering by Paul W. Cooper
Explosives Engineering Paul W. Cooper Review by: L. Weinman This book is intended as a non-trivial text for those interested in the technology and science that lies behind explosive events and devices. While the book starts with introductions to some very basic chemical concepts, this reviewer is of the opinion that the book’s intended audience …

Review of: Fireworks Principles and Practice by Ronald Lancaster
Fireworks Principles and Practice Ronald Lancaster Review by: Barry Sturman It is unlikely that many readers of these pages have not yet bought a copy of the third edition of the Reverend Ronald Lancaster’s Fireworks Principles and Practice (Chemical Publishing, New York, 1998). Those who have ignored this edition, because they already own first or second …

Review of: Pollution Caused by Fireworks – D. Gnauth White
Pollution Caused by Fireworks D. Gnauth White Review by: Monona Rossol In reference to the letter published in Issue 7, “Another Fog Study” by Monona Rossol, the data Ms. Rossol presented does not support her conclusion. The data indicates that something is happening during the performance to reduce the musicians’ lung function, but the data …

Peak In-Mortar Aerial Shell
K. L. and B. J. Kosanke ABSTRACT: Internal mortar pressures were measured for a range of somewhat typical fireworks aerial shell firing conditions. These data were used to determine the peak shell accelerations produced during firing. Under the conditions investigated, peak aerial shell acceleration ranged from approximately 4 to 16 km/s2 (400 to 1600 times …

Effect of Differing Charcoal Types Upon Handmade Lift Powder
Charles Wilson ABSTRACT: Experimental production of charcoal via the retort method is discussed. Charcoals were made from various substances; of special interest were woods belonging to the Salicaceae (willow) family. Lift powders were made using these charcoals and their performance compared using a device for testing powders under conditions similar to those used for propelling …

Combustion of Ti/C Pyrolants
Michinori Takizuka, Toshio Onda, Takuo Kuwahara, and Naminosuke Kubota ABSTRACT: The thermochemical characteristics of pyrolants composed of titanium (Ti) and carbon (C) were studied in order to develop high energy release materials used for igniters and fireworks. Since the Ti and C reaction occurs only at temperatures above 1200 K, polytetrafluoroethylene (PTFE) was mixed with …

Measurement of the Effectiveness of Various Mitigation Methods at Reducing the Projectile Hazards from Fragmenting Steel Firework Mortar Tubes
S. G. Myatt and M. R. Edwards ABSTRACT: Firework maroon shells were exploded inside mild steel spiral wound mortar tubes with various mitigation systems in place. It was found that the number of fragments was substantially reduced when the tube was prevented from expanding freely by sandbags or by burial of the tube in sand. …

High-Nitrogen Fuels for Low-Smoke Pyrotechnics
David E. Chavez, Michael A. Hiskey and Darren L. Naud* ABSTRACT: It has been demonstrated that the highnitrogen compound, 3,6-dihydrazino-s-tetrazine (DHT), can be utilized as a pyrotechnic fuel requiring small amounts of metal salts for coloring the flame. In addition, DHT pyrotechnic formulations using non-metallic oxidants, specifically ammonium perchlorate and ammonium nitrate, produce little smoke …
