1. Pre - operation Inspection
Visual Checks: Before any operation, conduct a thorough visual inspection of the storage fuel tank. Look for signs of corrosion, dents, cracks, or leaks on the tank body, valves, pipes, and fittings. Any visible damage should be reported immediately, and operations should not commence until the issue is resolved.
Instrument Calibration: Verify that all monitoring instruments, such as level gauges, pressure gauges, and temperature sensors, are calibrated correctly. Malfunctioning instruments can lead to over - filling, over - pressurization, or inaccurate fuel inventory management.
2. Filling Operations
Static Elimination: Before connecting the filling hose, ensure that static electricity is eliminated. Use grounding cables to connect the tank and the filling vehicle or equipment. This prevents the build - up of static charges, which could potentially ignite the fuel.
Flow Rate Control: Regulate the filling rate to avoid splashing and foaming. High - speed filling can generate static electricity and increase the risk of fire. Monitor the filling process continuously using the level gauges to prevent over - filling.
Ventilation Management: Ensure proper ventilation in the area during filling. Fuel vapors are flammable and can accumulate, creating an explosive atmosphere. Open vents or use exhaust systems to disperse the vapors.
3. Storage and Maintenance
Temperature and Pressure Control: Regularly monitor the temperature and pressure inside the tank. Extreme temperatures and pressures can cause the fuel to expand or evaporate, leading to leaks or explosions. Install temperature - regulating and pressure - relief devices, and set them to appropriate levels.Corrosion Prevention: Implement a corrosion - prevention program. This may include using corrosion - resistant coatings, inhibitors, or cathodic protection systems. Regularly inspect the tank for signs of corrosion and take appropriate measures to address it.
Spill Response Plan: Have a spill response plan in place. In the event of a fuel spill, immediately activate the plan, contain the spill, and clean it up using appropriate absorbent materials.
4. Emptying Operations
Valve and Hose Checks: Before emptying the tank, check the valves and hoses for any blockages or damage. Ensure that the receiving container is properly grounded and has sufficient capacity.
Monitoring and Shutdown: Monitor the emptying process closely. Once the tank is emptied, close all valves promptly to prevent air or contaminants from entering.
