Control of Static Electricity in Chemical Plants

Training Objectives

This course aims to explain:
(1) How electrostatic charge is generated
(2) How to recognize electrostatic discharges that can start fire or explosion in an industrial plant and
(3) The ways to control or eliminate electrostatic generation hazards. The attendees will learn practical techniques based on cases of electrostatic discharge explosions

Training Subjects

• Understanding electrostatic energy: what is static electricity; definitions; why take precautions
• Flammable atmospheres: relevant properties for the static ignition hazards
• Experimental testing: minimum ignition energy; resistivity, charge decay; powders chargeability
• Electrostatic hazards assessment: charge generation mechanisms; charge accumulation; discharging mechanisms
• Electrostatic control: facilities and people grounding; measures to be taken with liquids; measures to be adopted with powders; static electricity eliminators
• Exercise: the attendees will review a chemical production plant and will propose safeguards measures for electrostatic hazards preventing
• Historic cases: description of real incidents and summary of conditions that led to them; description of the measures adopted to prevent recurrence
