Strict Control of Flow Rates & Filling Methods
- Limit friction – strictly control flow rates to reduce friction between fuel and tank walls.
- Bottom filling preferred – minimises splashing and turbulence. If top filling is required, extend the discharge pipe deep into the tank and keep flow exceptionally low until fully submerged to prevent charge clouds.
Essential Grounding & Bonding Protocols
- Ground connection – electrically connect the tank to a dedicated ground rod or grounded metal structure before any fuel transfer.
- Bonding – use conductive cables and clamps to bond the tank to the refuelling equipment, eliminating potential differences between the two.
Mandatory Resting Periods After Transfer
- Allow charge dissipation – after fuel transfer, the fuel remains highly charged and requires time to safely dissipate.
- Strict waiting time – enforce resting periods before any manual measurements, sampling, or gauging, allowing static charges to bleed off through the grounded tank walls and reducing ignition risk.
Optimal Material Selection & Conductivity
- Conductive materials – steel alloys or aluminium allow charges to flow freely rather than accumulating on the surface.
- Internal components – hoses and pumps should be conductive or feature built‑in grounding wires. Anti‑static coatings can also be applied to non‑conductive parts to increase surface conductivity and prevent hazardous buildup.
