The Nature of Electrostatic Spark Hazards and Practical Measures for Control (AIHce EXP 2022 OnDemand)
Course Description:
Recorded at AIHce EXP 2022

A key concern in facilities working with flammable liquids and powders is the initiation of a flash fire or explosion by electrostatic discharges. A flammable atmosphere is created when a critical amount of a fuel is mixed with air. Ignition of flammable atmospheres can occur when the energy of the ignition source exceeds the minimum ignition energy of the flammable atmosphere. An electrostatic ignition source is a discharge (a spark) resulting from the generation and accumulation of electrostatic charges. Electrostatic charge generation most frequently occurs when any two materials, liquids and/or solids, make contact with each other and then separate. For example, when liquids flow relative to pipe walls or are atomized or when powder particles come into contact with the surfaces of the processing and conveying equipment. Accumulation of electrostatic charge on an object can result in electrostatic discharges. A flash fire or an explosion hazard therefore exists during the transfer, handling, processing (including spraying), and packaging of many flammable liquids and powders. Precautions must be taken to prevent inadvertent ignition and to protect people and/or the facility against the effects of explosions.

Learning Outcomes
At the end of this lecture, attendees will:
  • • Discuss how electrostatic charges are generated in industrial environments.
  • • Recognize those electrostatic hazards that can trigger industrial fires and explosions.
  • • Choose methods to evaluate and control electrostatic charges.
