Tanker Safety Checks Before Every Trip

Petroleum transport is a dangerous-goods operation, and the controls that keep it safe are mostly boring. The pre-trip inspection is the single most important routine in the operation, because it is the last point at which a defect can still be found before a loaded tanker is on a public road.

Walk-Around: Structure and Ground

Drivers check tyres for pressure, tread depth and sidewall damage, and brakes for response and pad wear. Wheel nuts are checked with a torque wrench - a loose wheel is the highest-severity defect in the fleet. The chassis, suspension and any visible leaks are inspected at the same time.

Compartment and Discharge System

Each compartment is opened and inspected for residue, corrosion or damage. Valves, seals, hoses and the discharge outlet are checked for weeping. On a multi-compartment tanker, contamination between compartments is a real risk: diesel residue in a compartment that carried petrol will ruin a customer's load and void the paperwork.

"A tanker that fails any check does not load. There is no exception and no negotiation on that rule."

Emergency and Fire Equipment

Fire extinguishers are checked for pressure and service date. Spill kits and emergency shut-off equipment are present and complete. Drivers confirm they are trained and currently certified for dangerous-goods carriage - certification is tracked centrally and a lapsed certificate takes a vehicle off the road.

Documentation and Load Plan

Before departure the driver confirms the delivery documentation, product, volume and destination match the dispatch order, and that the vehicle is carrying the correct placards and documentation for the product. A mismatch discovered at the other end is an expensive delay for the customer.

Signing the Vehicle Off

The inspection is recorded on a checklist with defects noted and signed by the driver. Any defect routes the vehicle to maintenance - it does not load while the fault is carried informally. That single habit is what separates a tanker fleet that arrives reliably from one that eventually does not.
