Static electricity can cause fires and explosions in chemical industries, so it's important to take precautions to prevent it. Here are some ways to reduce static electricity in chemical processing areas:
Grounding: Grounding equipment is a practical and effective way to reduce static electricity.
Control flow rates: Keep flow rates low or controlled to limit static generation.
Avoid splash filling: Avoid splash filling or misting operations.
Avoid free-falling liquids: Avoid dropping or allowing liquids to fall through the surface of stored liquids.
Use conductive materials: Use conductive flooring, shoe soles, and clothing to dissipate static charges.
Use antistatic additives: Add antistatic additives to liquids like fuel to increase conductivity.
Use inert gases: Add inert gases like helium or argon to areas where sparks might occur.
Use conductive surface coatings: Apply conductive surface coatings to non-conductive parts of the plant.
Maintain humidity: Use industrial humidifiers to maintain a humidity level above 60%.
Use antistatic wrist straps: Use antistatic wrist straps, also known as ESD wrist straps or ground bracelets, to prevent static buildup on the body.
Conduct periodic surveys: Use instruments like a gold leaf electroscope or electrostatic voltmeter to periodically survey static control measures
