Static Electricity Prevention Guide
Proper grounding procedures are essential for preventing static electricity hazards during fuel transfer operations
Select Appropriate Grounding Device
The adaptability of the grounding device is the foundation of effective static electricity prevention. Prioritize using a dedicated anti-static grounding clamp with high conductivity.
The clamp must fit snugly against metal parts of the tank to prevent poor contact. The grounding wire must be a copper-core cable with proper cross-sectional area and oil-resistant, wear-resistant insulation.
- Use dedicated anti-static grounding clamps
- Ensure clamp fits snugly on metal surfaces
- Select copper-core cables with proper specifications
- Use oil-resistant and wear-resistant cable insulation
Always verify that grounding equipment meets industry standards and is specifically designed for fuel handling environments.
Follow Standard Grounding Procedures
Proper operating procedures ensure effective grounding. Before grounding, clean oil and rust from the tank grounding area to ensure a clean metal surface for optimal conductivity.
Securely attach the grounding clamp to the metal body, avoiding coated or painted areas. If using a grounding electrode, ensure it is sufficiently deep into the ground and properly connected.
- Clean grounding area of oil, rust, and debris
- Attach clamp directly to bare metal surfaces
- Avoid painted or coated areas
- Ensure proper depth for grounding electrodes
Never attach grounding clamps to plastic components or painted surfaces as this will prevent effective static discharge.
Regularly Check Grounding Effectiveness
Regular inspections are crucial to maintaining grounding functionality. Before each use, check the grounding clamp for looseness or cable damage.
Use a ground resistance tester to verify the ground loop resistance meets safety standards. During operation, monitor for vibration and immediately address any grounding anomalies.
- Inspect clamps and cables before each use
- Test ground resistance regularly
- Monitor for vibration during operation
- Stop operations immediately if anomalies are detected
Establish a regular testing schedule and maintain detailed records of all grounding system inspections and tests.
Special Scenario Grounding Procedures
Special scenarios require targeted grounding protection. In dry environments, conduct grounding checks more frequently as static electricity accumulates more easily.
After moving tanks, always reconfirm grounding effectiveness. In areas with strong electromagnetic interference, check for impacts on the grounding system and implement shielding if needed.
- Increase inspection frequency in dry conditions
- Reconfirm grounding after tank movement
- Check for electromagnetic interference effects
- Implement shielding measures when necessary
Low humidity conditions significantly increase static electricity risks. Always implement enhanced grounding measures in dry environments.
