Does my dust collection system need explosion prevention in battery manufacturing?

In most cases, yes — especially if you're working with combustible materials like graphite, carbon black, or aluminum powder. These dusts can ignite when suspended in air and exposed to heat, static discharge, or friction. If your process involves combustible dust in sufficient quantities, NFPA standards (including NFPA 660, NFPA 68 and NFPA 69) require specific explosion protection measures. These may include explosion vents, isolation valves, chemical suppression systems, and proper electrical grounding. Your dust collection system must be designed not only for capture efficiency, but also for compliance with these safety standards.
