Safety Requirements and Hazards in Manufacturing of Carbonaceous Smoke Pyrotechnic Composition

摘要

Smoke composition are used in military warfares for various tactical roles. One of such screening composition has carbonaceous substance in form of pitch coal tar, along with sulphur, potassium nitrate, glue and Borax. The process of manufacture of composition involves making of pre-mix of various dry powder ingredients followed by slow addition of this premix to pre-melted pitch coal tar and glue in incorporator. The safety evaluation are made on the basis of the experimental data generation on this composition-by following conventional test methods like friction to direct mechanical shock, sensitiveness to friction temperature of Ignition, Behaviour of inflammation, chemical stability and environmental effects during manufacture. This paper underlines the hazards involved and its safety requirements during manufacture of composition.
