Electrostatic Hazards Associated with Liquids and Powder Processing

In many industrial settings, electrostatic hazards are the cause of injury, equipment damage, fires, and explosions. The crucial factor in evaluating these hazards is identifying where in the process electrostatic charge can be generated and accumulated.

This article explores the electrostatic hazards associated with liquid and powder processing. We discuss approaches for properly handling and processing these substances and for controlling risks associated with them, including:

  • Limiting liquid velocity
  • Bonding and grounding
  • Managing hazards during filtration and agitation
  • Charge reduction by humidification
  • Explosion protection
