Fuel Tank Standards in Kenya: Mild Steel vs Epoxy Finish

Materials: Mild Steel vs Epoxy Finish (The KEBS Role)

The two common options for tank construction are mild steel and epoxy finish. Under fuel tank standards in Kenya, materials must be selected to prevent leaks and resist corrosion over an extended service life. The Kenya Bureau of Standards (KEBS) ensures that materials meet national specifications.

Mild Steel (Primary Construction)

Mild steel is strong and common for building Above-Ground Storage Tanks (ASTs) and Underground Storage Tanks (USTs). To meet fuel tank standards in Kenya, the steel must be of a specific thickness and be correctly welded. For large commercial tanks, these construction standards often reference international codes like API Standard 650 and are enforced locally by KEBS. If not properly protected, mild steel is highly susceptible to rust and eventual leakage.

Epoxy Finish (Corrosion Protection)

Epoxy is a protective coating applied to the steel, usually on the interior and exterior of the tank, to enhance its longevity. It acts as a barrier to stop rust, especially from moisture and corrosive elements within the stored fuel. Using epoxy over steel is a best practice often required to meet fuel tank standards in Kenya for effective corrosion protection.

Installation Requirements

Installation must follow strict safety and engineering rules from fuel tank standards in Kenya to prevent accidents and contamination.

Base and Foundation

Tanks must sit on a solid, level concrete pad or foundation specifically engineered to support the full weight of the tank and its contents. This stops settlement, tipping, and allows for easy inspection.

Distance and Placement

Correct spacing is critical. Tanks must be placed a minimum distance away from buildings, property boundaries, and ignition sources (fire/sparks) as stipulated in fuel tank standards in Kenya to prevent fire spread.

Piping and Valves

All piping must be non-corrosive, securely connected, and pressure-tested. Safety features include emergency shut-off valves and clear marking of fuel lines for different products.

Safety, Compliance, and Licensing (EPRA & NEMA)

Safety is paramount. Compliance involves not only the physical tank structure but also obtaining the necessary permits from the relevant Kenyan regulatory bodies.

Spill Containment (The NEMA Mandate)

You must construct a bund wall or secondary containment system (often a concrete basin) around the tank. This structure must be liquid-tight and capable of holding at least 110% of the tank’s maximum capacity. This is a major requirement enforced by the National Environment Management Authority (NEMA) to prevent soil and water pollution in case of a spill.

Grounding and Venting

All tanks must be properly grounded (earthed) to discharge static electricity, which can cause sparks and fire. Vents must be installed to safely release air pressure and vapour build-up, adhering to fire and safety regulations.

Approvals and Records (The EPRA Licence)

To operate legally, you must secure a Petroleum Storage Licence from the Energy and Petroleum Regulatory Authority (EPRA). This licence requires:

• A Fire Clearance Certificate from the County Government.
• A valid Environmental Impact Assessment (EIA) Licence from NEMA.
• Certification from KEBS confirming the facility conforms to the applicable Kenya Standards (like KS EAS 977:2020 for installation).
• A valid certificate of registration as a workplace from the Directorate of Occupational Safety and Health Services (DOSHS).
• A detailed Emergency Response Plan.

Keep all inspection and calibration records updated to demonstrate that your tank complies with fuel tank standards in Kenya.

Simple Maintenance Tips

Proper care keeps tanks safe and extends their lifespan, aligning with fuel tank standards in Kenya‘s goal of preventing failure.

• Weekly Visual Check: Inspect for external signs of rust, peeling epoxy, leaks, or ground settlement.
• Regular Cleaning: Clean filters and ensure valves are working smoothly and not corroded.
• Corrosion Management: Recoat the tank with epoxy immediately if the protective layer is compromised.
• Calibration & Inspection: Arrange for periodic calibration and professional inspection by certified engineers (often mandated by EPRA and DOSHS).
