Electrostatic Protection System
Comprehensive safety measures for Self Bunded Tanks
The electrostatic protection system of a Self Bunded Tank is a coordinated set of components designed to prevent the buildup and discharge of static electricity—an invisible hazard that can ignite flammable vapors or cause damage to the tank and its contents.
Grounding (Earthing)
- Redirects static charges to the earth through dedicated grounding points
- Uses conductive materials like copper or brass for connections
- Creates a low-resistance path for charges to flow into the earth
- Prevents voltage buildup that could lead to sparks
Conductive Materials and Coatings
- Ensures even distribution of static charge across the tank structure
- Applied to non-conductive surfaces to prevent charge concentration
- Reduces risk of static discharge by spreading charge evenly
- Facilitates easier dissipation through the grounding system
Static Dissipative Hoses and Fittings
- Used during liquid transfer for highly volatile liquids
- Made with conductive fibers to prevent static buildup
- Connected to the tank's grounding system
- Immediately grounds any charge generated during transfer
Static Monitoring Devices
- Tracks charge levels in real time using sensors
- Triggers alerts when charge levels exceed safe thresholds
- Allows proactive intervention before hazards develop
- Enables operators to pause transfers and check connections
Operator Safety Measures
- Requires use of grounding straps or wristbands
- Connects operators to the tank's grounding system
- Prevents static buildup on personnel
- Eliminates risk of human-related static discharge
In summary, the electrostatic protection system of a Self Bunded Tank works through a multi-layered approach: grounding redirects charges to the earth, conductive materials prevent charge concentration, specialized transfer components limit static generation during liquid movement, monitoring devices provide real-time safety checks, and operator tools eliminate human-related risks.
