72 Effectively controlling workplace conditions Before Installation of Containment Equipment • Manual charging of powders into reactor and mixing vessel. • Potential employee exposure exists due to generation of airborne particulates during manual charging. • Supplied air breathing suit was primary line of defense. Powder Transfer System with Drum Containment System After Installation of Containment Equipment • Reduction in employee exposure during handling of powders. • Minimized manual intervention. • Charging of powder via Drum Containment System (DCS) and Powder Transfer System (PTS) • Minimization of dust explosion. • Capability of handling powders having OEL less than 1 µg/m3. Actions Taken • Mapping of containment equipment based on operations performed. • Powder Transfer System, Isocharge, Drum Containment System to charge solids. • Continuous Liner ports during unloading via ANFD. • Dispensing isolator for dispensing of powder at warehouse. • Recipe based automated distant control system for manufacturing operation.
