Challenges in the Design of Safe
Handling System for Explosive Dust
Nagababu Kurakula and Elangovan Muniyandy
Abstract Powders manufacturing industries have been growing significantly for the
past few decades due to their economic benefits of producing net-shaped or nearnet-shaped components compared with conventional metal-working methods. The
incidents related to fires and explosions due to powders are unfortunately regular
occurrences throughout the world with many injuries to severe injuries and fatalities
every year. It is observed that 30% of the industrial accidents are occurred due to
dust explosions and also happened in the dust collection systems. But there are no
explicit studies carried out on the handling of explosive dust, which are potentially
hazardous with their sensitivities viz., friction, heat, vibration, and impact and static.
Since these are uncommon materials used in the industries; no reliable data has
been established for the safe handling of explosive dust by different dust collectors.
Aerospace and military industries are operating the explosive materials for different
applications. Dust is generated during the manufacturing of various components of
the rocket for space applications. Explosive machining is one of the critical operations in rocket production. Dust generated during explosive grain machining shall be
properly collected and carefully handled to mitigate the associated potential risks.
In order to meet this challenging task of collecting highly hazardous dust, a safe
and healthy collection extraction system is inevitable. To address the above challenge, a suitable dust collection system is designed by considering various critical
parameters. System worthiness for safe handling of dust is verified using risk control
technique ETA. The designed system minimizes the manual cleaning and provides
provision for easy maintenance. This paper deals with the challenges in designing
a suitable collection system for explosive dust and verification its worthiness using
ETA.
