FuelGuard public advisory — South Africa
Farms, fleets and bulk fuel users should test and document every incoming diesel delivery before accepting it into operational stock. A consistent receiving procedure helps identify unexpected density variation, visible contamination and free water before the fuel reaches vehicles or equipment.
Recommended receiving controls
- Confirm the supplier, delivery note, product grade and delivered quantity.
- Take a representative sample before or during transfer.
- Check the sample visually for haze, sediment, separation or free water.
- Measure and record density and temperature using suitable equipment and the applicable reference method.
- Photograph the sample and instrument readings, and retain the result with the delivery record.
- Keep the fuel isolated if the result falls outside the organisation’s approved control range or contamination is suspected.
If a result is unusual
Do not rely on one reading as proof of wrongdoing or non-compliance. Repeat the test, confirm the test method and equipment, preserve a properly labelled sample, notify the supplier and obtain competent technical or laboratory assistance where appropriate.
This advisory is a preventive operational control and does not identify any supplier or allege misconduct.
