Investigations on thermokinetic and mechanical sensitivities of fireworks mixtures

Abstract

Fireworks mixtures are highly energetic compounds susceptible to explosive degradations on ignition impact and friction Several accidents during processing storage and transportation have been reported in Indian fireworks manufacturing units An analysis of accident data reported in the fireworks units during 1989 2013 in India has shown that the main cause of an accident is inadequate knowledge of the mechanical thermal and electrostatic sensitivity of fireworks mixtures Nevertheless the sensitivity of newlinea mixture to its explosion cannot be theoretically predicted as it depends on the reactive nature of the mixture components and the conditions employed during its preparation and handling Though Material Safety Data Sheets of pure chemicals are readily available no such data are available for mixtures Additionally the mixture s composition varies from company to company for the same type of application newline
