• Bunded (double-walled) tanks for spill protection and environmental compliance

1. Read Manufacturer Instructions
   Follow all operational and safety guidelines provided by the bowser manufacturer.
2. Wear PPE (Personal Protective Equipment)
   Use gloves, eye protection, and flame-resistant clothing when handling fuel.
3. Ensure Proper Grounding
   Ground the bowser to prevent static discharge during bulk fuel transfers.
4. Turn Off Engines
   Make sure all vehicles or machinery being refuelled are switched off.
5. Use Certified Components
   Only use nozzles and hoses rated for fuel use; check them for cracks or wear.
6. Avoid Overfilling
   Monitor sight gauges and flow meters to prevent fuel overflow or spillage.
7. Keep Fire Extinguishers Nearby
   A Class B-rated fire extinguisher should be easily accessible at all times.
8. No Ignition Sources
   Enforce a strict no-smoking/no-flame zone around the fuel bowser.

• Regular Inspections
• Check hoses, nozzles, meters, and seals for damage, wear, or leaks.
• Filter Replacements
• Change fuel filters regularly to ensure clean fuel delivery.
• Pump Servicing
• Test the pump motor, seals, and electrical connections for proper function.
• Tank Cleaning
• Clean the fuel tank periodically to remove sludge, water, or algae buildup.
• Flow Meter Calibration
• Recalibrate flow meters as needed to ensure accurate fuel measurement.
• Bunding Inspection (if applicable)
• Inspect bunded areas for cracks, leaks, and sufficient containment capacity.

• • Self-Bunded Tanks: These double-walled tanks have built-in secondary containment to prevent leaks and spills. Ideal for above-ground use on farms, construction sites, and industrial areas. They’re compliant with most Australian safety standards.
  • Single-Skinned Tanks: These tanks consist of a single wall and require separate bunding or containment measures. Typically used in less regulated environments or within containment areas.
  • Portable Diesel Tanks: Small, mobile tanks often mounted on utes, trailers, or trolleys. Suitable for onsite refuelling of vehicles and machinery.
  • Underground Diesel Tanks: Used in commercial fuel stations or large-scale industrial setups. They help save space and protect fuel from temperature fluctuations but require extensive regulatory compliance.
  • Poly Diesel Tanks: Made from high-density polyethylene, these tanks are corrosion-resistant and lightweight, suitable for portable or stationary use.
  • Transport-Approved Tanks (IBC Diesel Tanks): Intermediate Bulk Containers (IBCs) designed for safe and legal transport of diesel under Australian Dangerous Goods (ADG) Code regulations.
  • How Do I Maintain a Diesel Storage Tank?

• • Regular Inspections: Check for corrosion, leaks, cracks, and worn fittings—especially around pumps, valves, and seals.
  • Water Removal: Diesel can absorb moisture, leading to microbial growth and fuel contamination. Drain water from the bottom of the tank regularly.
  • Filter Changes: Replace fuel filters on dispensers and pumps as part of routine service.
  • Tank Cleaning: Clean the inside of the tank periodically to remove sludge, sediment, and microbial build-up (diesel bug).
  • Protect From UV and Heat: For poly and above-ground tanks, use covers or shelters to reduce sun exposure and temperature variations.
  • Fuel Testing: Periodically test stored diesel for water content, microbial activity, and degradation—especially for tanks storing fuel long-term.

• • AS 1940 Compliance: Tanks must comply with AS 1940: The Storage and Handling of Flammable and Combustible Liquids, which sets guidelines for tank construction, placement, bunding, and fire safety.
  • Bund Requirements: Above-ground tanks must have secondary containment (bunds) capable of holding 110% of the largest tank’s capacity to prevent environmental contamination.
  • Ventilation and Signage: Adequate venting, emergency signage, and spill kits are required onsite.
  • Environmental Regulations: Operators must comply with EPA and local council requirements regarding site planning, drainage protection, and spill control.
  • Transport Compliance (ADG Code): Portable and mobile tanks must meet the Australian Dangerous Goods Code requirements if transported.
  • Workplace Health & Safety (WHS): Employers must provide training, maintain safety data sheets (SDS), and manage risks under WHS regulations.

Self-Bunded Diesel Tank

What maintenance is required for self-bunded diesel tanks?

Regular maintenance of self-bunded diesel tanks is essential to ensure fuel quality, prolong equipment life, and meet environmental compliance standards. Key maintenance practices include:

• Routine inspections: Visually check the tank’s inner and outer walls for corrosion, leaks, or structural damage.
• Check fuel levels and usage: Use dipsticks, gauges, or monitoring systems to ensure accurate readings and detect anomalies.
• Remove water and sediment: Diesel can attract water and microbial growth. Drain the water trap periodically and clean out sludge buildup.
• Service pumps and filters: Clean or replace fuel filters regularly to maintain flow and prevent contamination.
• Inspect hoses, fittings, and valves: Look for wear, cracks, or loose connections to prevent fuel leaks or pressure issues.
• Test bund integrity: Ensure the outer bund can contain any leaks from the inner tank and remains structurally sound.
• Document maintenance: Maintain accurate records of inspections, servicing, and repairs for audit and compliance purposes.

Following a scheduled maintenance routine reduces costly downtime, extends equipment lifespan, and maintains diesel purity—especially under harsh Australian conditions.

How do I ensure compliance with safety standards?

To comply with Australian safety and environmental regulations for self-bunded diesel tanks, follow these key steps:

1. Adhere to AS 1940 standards: Ensure that tank design, installation, and maintenance meet the AS 1940 – Storage and Handling of Flammable and Combustible Liquids standard.

2. Site planning approval: Obtain necessary approvals from local councils or environmental authorities before installation.

3. Secondary containment: Ensure the bund can contain at least 110% of the tank's capacity or meets relevant regulations.

4. Proper signage and labelling: Use compliant hazard and fuel identification labels as per WHS requirements.

5. Spill response preparedness: Keep spill kits, fire extinguishers, and safety data sheets (SDS) on site.

6. Scheduled inspections and documentation: Maintain logs of inspections, servicing, and any repairs.

7. Trained personnel: Ensure all staff handling diesel are trained in proper handling and emergency procedures.

These practices help maintain regulatory compliance, improve safety, and minimise business liability.

Can self-bunded diesel tanks be relocated?

Yes, self-bunded diesel tanks are designed for relocation, making them an efficient and cost-effective choice for dynamic job sites. Their integrated double-wall design removes the need for external bunding, simplifying transport and setup.

Key considerations when relocating a tank:

• Drain fuel if required: Some sites or transport companies may require partial or full emptying for safe transport.
• Use designated lifting points: Most tanks feature engineered lifting lugs or forklift pockets to ensure safe handling.
• Conduct reinspections post-move: After relocation, inspect for transport-related damage and verify the condition of pumps, fittings, and the bund.
• Update site compliance: Ensure the new location meets all local environmental and safety requirements.

Self-bunded tanks are ideal for industries like construction, agriculture, and mining—where on-site fuel flexibility is crucial without compromising safety or compliance.
